Background: Mental health problems are common among university students, yet many students do not seek professional help. Digital mental health interventions can increase students' access to support and have been shown to be effective in preventing and treating mental health problems. However, little is known about the extent to which students implement therapeutic skills from these programs in everyday life (ie, skill enactment) or about the impact of skill enactment on outcomes., Objective: This study aims to assess the effects of a low-intensity video-based intervention, Uni Virtual Clinic Lite (UVC-Lite), in improving skill enactment relative to an attention-control program (primary aim) and examine whether skill enactment influences symptoms of depression and anxiety (secondary aim). The study also qualitatively explored participants' experiences of, and motivations for, engaging with the therapeutic techniques., Methods: We analyzed data from a randomized controlled trial testing the effectiveness of UVC-Lite for symptoms of depression and anxiety among university students with mild to moderate levels of psychological distress. Participants were recruited from universities across Australia and randomly assigned to 6 weeks of self-guided use of UVC-Lite (243/487, 49.9%) or an attention-control program (244/487, 50.1%). Quantitative data on skill enactment, depression, and anxiety were collected through baseline, postintervention, and 3- and 6-month follow-up surveys. Qualitative data were obtained from 29 intervention-group participants through open-ended questions during postintervention surveys (n=17, 59%) and semistructured interviews (n=12, 41%) after the intervention period concluded., Results: Mixed model repeated measures ANOVA demonstrated that the intervention did not significantly improve skill enactment (F 3,215.36 =0.50; P=.68). Skill enactment was also not found to influence change in symptoms of depression (F 3,241.10 =1.69; P=.17) or anxiety (F 3,233.71 =1.11; P=.35). However, higher levels of skill enactment were associated with lower symptom levels among both intervention and control group participants across time points (depression: F 1,541.87 =134.61; P<.001; anxiety: F 1,535.11 =73.08; P<.001). Inductive content analysis confirmed low levels of skill enactment among intervention group participants. Participants were motivated to use techniques and skills that were perceived to be personally relevant, easily integrated into daily life, and that were novel or had worked for them in the past., Conclusions: The intervention did not improve skill enactment or mental health among students with mild to moderate psychological distress. Low adherence impacted our ability to draw robust conclusions regarding the intervention's impact on outcomes. Factors influencing skill enactment differed across individuals, suggesting that it may be necessary to tailor therapeutic skills and engagement strategies to the individual user. Theoretically informed research involving collaboration with end users is needed to understand the processes underlying skill enactment in digital mental health interventions., Trial Registration: Australian New Zealand Clinical Trials Registry ACTRN12621000375853; https://tinyurl.com/7b9ar54r., (©Hayley M Jackson, Philip J Batterham, Alison L Calear, Jeneva L Ohan, Louise M Farrer.

Background: Numerous studies have demonstrated the effectiveness of digital interventions for improving the mental health of university students. However, low rates of engagement with these interventions are an ongoing challenge and can compromise effectiveness. Brief, transdiagnostic, web-based video interventions are capable of targeting key mental health and related issues affecting university students and may be more engaging and accessible for this population., Objective: This study used a 2-arm randomized controlled trial to evaluate the effectiveness of Uni Virtual Clinic-Lite (UVC-Lite), a fully automated, transdiagnostic, web-based video intervention, relative to an attention-control condition. The primary outcomes were symptoms of depression and generalized anxiety disorder. The secondary outcomes included psychological distress, social anxiety symptoms, body appreciation, quality of life, well-being, functioning, general self-efficacy, academic self-efficacy, and help seeking. Program use (intervention uptake and engagement) and satisfaction were also assessed., Methods: University students (n=487) with mild to moderate symptoms of distress were recruited from universities across Australia and randomly allocated to receive access to the UVC-Lite intervention or an attention-control condition targeting general health for a period of 6 weeks. UVC-Lite includes 12 modules, each comprising a brief animated video and an accompanying exercise. Of the 12 modules, 7 also included a brief symptom screening quiz. Outcomes were assessed at baseline, postintervention, and 3- and 6-months postintervention., Results: The primary and secondary outcomes were analyzed on an intention-to-treat basis using mixed models repeated measures ANOVA. The intervention was not found to be effective relative to the control condition on any of the primary or secondary outcomes. While 67.9% (114/168) of participants accessed at least 1 module of the intervention, module completion was extremely low. Subgroup analyses among those who engaged with the program (completed at least 1 video) and those with higher baseline distress (Distress Questionnaire-5 score ≥15) did not reveal any differences between the conditions over time. However, uptake (accessing at least 1 video) and engagement (completing at least 1 video) were higher among those with higher baseline symptoms. Satisfaction with the intervention was high., Conclusions: The UVC-Lite intervention was not effective relative to a control program, although it was associated with high satisfaction among students and was not associated with symptom deterioration. Given the challenges faced by universities in meeting demand for mental health services, flexible and accessible interventions such as UVC-Lite have the potential to assist students to manage symptoms of mental health problems. However, low uptake and engagement (particularly among students with lower levels of symptomatology) are significant challenges that require further attention. Future studies should examine the effectiveness of the intervention in a more highly symptomatic sample, as well as implementation pathways to optimize effective engagement with the intervention., Trial Registration: Australian New Zealand Clinical Trials Registry ACTRN12621000375853; https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=380146., (©Louise M Farrer, Hayley M Jackson, Amelia Gulliver, Alison L Calear, Liana Leach, Penelope Hasking, Natasha Katruss, Philip J Batterham.

Background: The acquisition of knowledge and use of skills from digital mental health interventions (DMHIs) are considered important for effectiveness. However, our understanding of user experiences implementing skills learned from these interventions is limited, particularly outside of research trials. This qualitative study aimed to investigate how community users learn and apply knowledge and skills from DMHIs based on cognitive behavioural therapy (CBT) in daily life. The study also examined factors influencing the selection and use of skills and explored perceived changes in mental health resulting from the intervention., Methods: Thirteen adults aged 26 to 66 years (10 females) were recruited using social media advertising and participated in semi-structured interviews by telephone or videoconference. All participants were living in Australia and had used a digital CBT program within the past 3 months. Interviews lasted on average 45 min. Transcripts were analysed using theoretical thematic analysis., Results: Participants demonstrated high levels of program engagement. Findings were organised into three topics with six major themes. Participants reported that their chosen intervention reinforced existing knowledge and fostered new skills and insights (Topic 1, Theme 1: knowledge consolidation). Most described actively applying skills (Topic 1, Theme 2: active approach to skill enactment), although the extent of learning and range of skills enacted varied across participants. Influences on skill selection included the perceived relevance of intervention strategies to the user's needs and personal characteristics (Topic 2, Theme 1: relevance of intervention strategies), as well as the perceived or experienced effectiveness of those strategies (Topic 2, Theme 2: perceived and experienced benefit). Challenges to ongoing skill enactment included time scarcity, prioritisation difficulties, and lack of motivation (Topic 2, Theme 3: navigating time constraints and low motivation). Improvements in mental health were generally modest and attributed mainly to participants' proactive efforts (Topic 3, Theme 1: perceived changes)., Conclusions: DMHIs may reinforce existing understanding of psychotherapeutic strategies, offer new knowledge, and encourage the application of skills in everyday life among community users who actively engage with these interventions. Future research should prioritise personalising DMHIs and investigating methods to optimise the acquisition, retention, and sustained application of knowledge and skills., (© 2024. The Author(s).)

Introduction: Rates of help-seeking for mental disorders and suicide are low among children and adolescents. Parents are viewed as gatekeepers for their care, yet they may lack the knowledge and skills to identify needs or facilitate service access. The primary aim is to test the effect of a new gatekeeper resource for parents and caregivers on their self-efficacy to recognise, respond and access support for mental health problems and suicide risk in their child., Methods and Analysis: A two-arm randomised controlled trial will compare an online mental health and suicide gatekeeper resource for parents and caregivers to a waitlist control. Australian parents of children aged 5-17 years recruited through social media and community advertising will participate in an online trial. Participants randomised to the intervention condition will be emailed the resource to work through at their own pace. The resource consists of three sections providing parents and caregivers with confidence, knowledge and skills to recognise and respond to mental health problems and suicide risk in their child, as well as support them in accessing professional help. The primary outcome measure is self-efficacy to recognise, respond and provide support for mental health problems and suicide risk, while secondary outcomes include perceived knowledge, stigma, literacy, help-seeking attitudes, intentions and barriers. Data will be collected at preintervention, postintervention (4 weeks after accessing the resource) and 12-week follow-up. Primary analyses will compare changes in self-efficacy in the intervention condition relative to the waitlist control using mixed-model repeated measures analyses., Ethics and Dissemination: The ethical aspects of the study were approved by the Australian National University Human Research Ethics Committee (Protocol 2023/195). If effective, the resource will fill an important gap in resources for parents, with the potential for dissemination through school groups, community organisations and clinical settings., Trial Registration Number: Australian New Zealand Clinical Trials Registry, ACTRN12623000933651., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Introduction: This study aimed to investigate the mechanisms of the development of suicidal ideation and its moderating and protective factors. Drawing on the Interpersonal-psychological theory of suicide, we proposed that disruptions to belongingness, in conjunction with tolerance of health risk, may influence the development of suicidal ideation above and beyond psychosocial changes such as disruptions to finances and work., Methods: The study involved a longitudinal investigation of an Australian representative sample reporting suicidal ideation fortnightly for 12 weeks between March and June 2020., Results: The results indicated that participants who reported higher levels of belongingness, mastery, and intolerance of health risk were less likely to experience suicidal ideation and had lower severity of suicidal ideation. Mastery significantly strengthened the negative link between belongingness and the incidence of suicidal ideation, while agreeableness significantly strengthened the negative link between belongingness and the severity of suicidal ideation over time., Conclusion: The findings suggest that supporting effective social connectedness during times of isolation and promoting self-efficacy, mastery, and regulation of risk tolerance, may be crucial for suicide prevention and therapeutic intervention., (© 2024 The Authors.

Background: Two of the most common modifiable barriers to help-seeking for mental health problems during adolescence are stigma and poor mental health literacy. However, relatively little is known about stigma as it relates to suicide, and knowledge about suicidality in this age group., Aims: To assess levels of suicide literacy and suicide attitudes in an adolescent sample, and to identify correlates of these constructs., Methods: Data were drawn from the pre-intervention survey of the Sources of Strength Australia Project. A total of 1019 adolescents aged between 11 and 17 years participated. Suicide literacy and attitudes were measured alongside potential correlates including psychological distress, suicidal ideation, mastery, previous exposure to suicidal thinking and behaviour, and demographics., Results: Participants more strongly endorsed attitudes attributing suicide to isolation/depression, compared to attitudes glorifying or stigmatising suicide. Gaps in knowledge about suicide included the risk factors, signs and symptoms. Key correlates of suicide attitudes and literacy included age, gender and cultural background., Conclusion: Findings highlight the need for further education activities in schools and public awareness campaigns that address the gaps in suicide knowledge and attitudes. Such activities would assist in the identification of suicide risk among young people and improve help-seeking in this population.

Purpose: As environmental disasters become more common and severe due to climate change, there is a growing need for strategies to bolster recovery that are proactive, cost-effective, and which mobilise community resources., Aims: We propose that building social group connections is a particularly promising strategy for supporting mental health in communities affected by environmental disasters., Methods: We tested the social identity model of identity change in a disaster context among 627 people substantially affected by the 2019-2020 Australian fires., Results: We found high levels of post-traumatic stress, strongly related to severity of disaster exposure, but also evidence of psychological resilience. Distress and resilience were weakly positively correlated. Having stronger social group connections pre-disaster was associated with less distress and more resilience 12-18 months after the disaster, via three pathways: greater social identification with the disaster-affected community, greater continuity of social group ties, and greater formation of new social group ties. New group ties were a mixed blessing, positively predicting both resilience and distress., Conclusions: We conclude that investment in social resources is key to supporting mental health outcomes, not just reactively in the aftermath of disasters, but also proactively in communities most at risk., (© 2023.

Background: Body satisfaction is associated with mental health and well-being in adults. However, prospective studies are needed to better understand its protective effects, and in whom these are most beneficial. This study investigated body satisfaction as a predictor of depressive symptoms, generalised anxiety, and well-being in a representative Australian sample collected during the initial COVID-19 lockdown. Two emotion regulation strategies - cognitive reappraisal and expressive suppression - were also tested as moderating variables., Methods: The sample comprised 684 adults aged 19 to 87 years who completed three primary waves of data spanning two months [Wave 3 (W3), W4 and W7] from the Australian National COVID-19 Mental Health, Behaviour and Risk Communication Survey., Results: Hierarchical multiple regression models controlling for demographic and COVID-19 risk factors, as well as W3 for each outcome variable, indicated that W3 body satisfaction predicted greater W7 well-being, and fewer W7 depressive symptoms and greater W7 well-being in participants reporting low levels of W4 cognitive reappraisal. No moderation for W4 expressive suppression was observed, nor predictive relationships between W3 body satisfaction and W7 anxiety., Limitations: The two-month follow-up period precludes conclusions relating to the longer-term protective effects of body satisfaction within and beyond the pandemic context. Examination of focal relationships in clinical samples, and inclusion of broader indices of body image, emotion regulation and mental health, is needed in future studies., Conclusions: Findings suggest body satisfaction warrants attention in community well-being promotion in adults, and may be particularly beneficial for those lack adaptive emotion regulation strategies., Competing Interests: Declaration of competing interest None to declare., (Copyright © 2024 The Authors.

Background: Mental disorders are common in childhood, but many young people do not receive adequate professional support. Help-seeking interventions may bridge this treatment gap, however, there is limited research on interventions for primary-school children. This study aims to evaluate the effectiveness of an emotion literacy program at increasing literacy, reducing stigma, and promoting help-seeking in children aged 8-10 years., Methods and Analysis: A two-arm pragmatic cluster-controlled trial will compare Thriving Minds, an emotion literacy program for middle primary school children, to a wait-list control condition. Children aged 8-10 years will be recruited from approximately 12 schools (6 intervention schools/6 wait-list control) to participate in Thriving Minds via direct invitation by the program delivery service. Allocation to the intervention condition will be pragmatically, by school. Children will receive the intervention over two 50-minute sessions, across two weeks. Using story books and interactive discussion, the program aims to develop children's knowledge of their own and other's emotional experiences and emotion regulation strategies (self-care and help-seeking). The primary outcome is help-seeking intentions. Secondary outcomes include help-seeking knowledge, attitudes, and behaviours, emotion knowledge and attitudes, and stigma. Children will complete surveys at pre-intervention, post-intervention (one week after the program) and 12-week follow-up. Additional satisfaction data will be collected from teachers in intervention schools via surveys (post-intervention and 3-month follow-up) and semi-structured interviews (after follow-up), and selected children via focus groups (12-week follow-up). Analyses will compare changes in help-seeking intentions relative to the waitlist control condition using mixed-model repeated-measures analyses to account for clustering within schools., Discussion: With demonstrated effectiveness, this universal emotion literacy program for promoting help-seeking for mental health could be more widely delivered in Australian primary schools, providing a valuable new resource, contributing to the mental health of young people by improving help-seeking for early mental health difficulties., Trial Registration: Australian New Zealand Clinical Trials Registry, ACTRN12623000910606 Registered on 24 August 2023., (© 2024.

Witnessing degradation and loss to one's home environment can cause the negative emotional experience of solastalgia. We review the psychometric properties of the 9-item Solastalgia subscale from the Environmental Distress Scale (Higginbotham et al. (EcoHealth 3:245-254, 2006)). Using data collected from three large, independent, adult samples (N = 4229), who were surveyed soon after the 2019/20 Australian bushfires, factor analyses confirmed the scale's unidimensionality, while analyses derived from Item Response Theory highlighted the poor psychometric performance and redundant content of specific items. Consequently, we recommend a short-form scale consisting of five items. This Brief Solastalgia Scale (BSS) yielded excellent model fit and internal consistency in both the initial and cross-validation samples. The BSS and its parent version provide very similar patterns of associations with demographic, health, life satisfaction, climate emotion, and nature connectedness variables. Finally, multi-group confirmatory factor analysis demonstrated comparable construct architecture (i.e. configural, metric, and scalar invariance) across validation samples, gender categories, and age. As individuals and communities increasingly confront and cope with climate change and its consequences, understanding related emotional impacts is crucial. The BSS promises to aid researchers, decision makers, and practitioners to understand and support those affected by negative environmental change., (© 2024. The Author(s).)

Objective: There is limited evidence of the direct effects of COVID-19 infection on mental health, and whether these are influenced by vaccination or physical health symptoms. We aimed to investigate the relationships of COVID-19 infection, current symptom presentation, and vaccination status with mental health symptoms in adults., Study Design and Setting: A cross-sectional sample of the Australian adult population that was representative by age, gender, and location was recruited through market research panels (N = 1407, 51.3% female, mean age 47.9 years). Hierarchical regression analyses were used to examine the associations of COVID-19 infection history and current COVID-19 symptoms with symptoms of depression (Patient Health Questionnaire-9), generalized anxiety (Generalized Anxiety Disorder-7) and social anxiety (Mini-Social Phobia Inventory)., Results: COVID-19 infection was associated with significantly higher depression and anxiety symptoms, but only in those who were not fully vaccinated. Current experience of COVID-related symptoms was associated with significantly higher depression and anxiety symptoms, and attenuated the direct effect of infection on mental health outcomes to non-significance., Conclusion: COVID-19 infection may be associated with increased mental health symptoms. However, the effects of infection on mental health were primarily evident in those who were not fully vaccinated and were explained by greater physical health problems associated with COVID-19 infection. The findings reinforce the efficacy of vaccination for reducing physical and mental health symptoms following infection., Competing Interests: Declaration of competing interest The authors have no competing interests to report., (Copyright © 2024 The Authors.

Aims: We assessed the mental health effects of Australia's 2019-2020 bushfires 12-18 months later, predicting psychological distress and positive psychological outcomes from bushfire exposure and a range of demographic variables, and seeking insights to enhance disaster preparedness and resilience planning for different profiles of people., Methods: We surveyed 3083 bushfire-affected and non-affected Australian residents about their experiences of bushfire, COVID-19, psychological distress (depression, anxiety, stress, post-traumatic stress disorder) and positive psychological outcomes (resilient coping, wellbeing)., Results: We found high rates of distress across all participants, exacerbated by severity of bushfire exposure. For people who were bushfire-affected, being older, having less financial stress, and having no or fewer pre-existing mental disorders predicted both lower distress and higher positive outcomes. Being male or having less income loss also predicted positive outcomes. Severity of exposure, higher education and higher COVID-19-related stressors predicted both higher distress and higher positive outcomes. Pre-existing physical health diagnosis and previous bushfire experience did not significantly predict distress or positive outcomes., Recommendations: To promote disaster resilience, we recommend investment in mental health, particularly for younger adults and for those in rural and remote areas. We also recommend investment in mechanisms to protect against financial distress and the development of a broader definition of bushfire-related impacts than is currently used to capture brushfires' far-reaching effects., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article.

Effective implementation strategies are important for take-up of programs in schools. However, to date, few implementation strategies have been co-designed with teachers and support staff (including principals) in Australia. The aim of this study was to iteratively co-design multiple implementation strategies to enhance the delivery of mental health prevention program, PAX Good Behaviour Game, in New South Wales primary schools. The secondary aim was to evaluate the acceptability of the implementation strategies from the perspective of school staff. Twenty-nine educational staff (including principals) informed the co-design of the implementation strategies across three phases. Phase 1 involved a rapid review of the literature and stakeholder meetings to agree upon potential evidence-based strategies. Phase 2 involved focus group discussions with educational staff to co-design implementation strategies. Phase 3 involved semi-structured interviews with school staff to assess strategy acceptability after implementation at 6-months post-baseline. Data were analysed using deductive, framework analysis. The final co-designed intervention included nine implementation strategies accessible through a toolkit delivered to the school's leadership team. These strategies were deemed acceptable in school settings that experienced periods of both face-to-face and remote learning due to the changing COVID-19 situation in 2021. This paper contributes to the implementation literature by transparently reporting how educational staff-informed implementation strategies were iteratively co-designed. This will provide a roadmap for other researchers to co-design implementation strategies to further support the delivery of evidence-based prevention programs in schools., (© 2023. The Author(s).)

Background: The factors that influence transition from suicidal ideation to a suicide attempt or remission of suicidal thoughts are poorly understood. Despite an abundance of research on risk factors for suicidal ideation, no large-scale longitudinal population-based studies have specifically recruited people with suicidal ideation to examine the mechanisms underlying critical transitions to either suicide attempt or recovery from suicidal ideation. Without longitudinal data on the psychological, behavioural, and social determinants of suicide attempt and the remission of suicidal ideation, we are unlikely to see major gains in the prevention of suicide., Aim: The LifeTrack Project is a population-based longitudinal cohort study that aims to identify key modifiable risk and protective factors that predict the transition from suicidal ideation to suicide attempt or remission of suicidal ideation. We will assess theory-informed risk and protective factors using validated and efficient measures to identify distinct trajectories reflecting changes in severity of suicidal ideation and transition to suicide attempt over three years., Methods: A three-year prospective population-based longitudinal cohort study will be conducted with adults from the general Australian population who initially report suicidal ideation (n = 842). Eligibility criteria include recent suicidal ideation (past 30 days), aged 18 years or older, living in Australia and fluent in English. Those with a suicide attempt in past 30 days or who are unable to participate in a long-term study will be excluded. Participants will be asked to complete online assessments related to psychopathology, cognition, psychological factors, social factors, mental health treatment use, and environmental exposures at baseline and every six months during this three-year period. One week of daily measurement bursts (ecological momentary assessments) at yearly intervals will also capture short-term fluctuations in suicidal ideation, perceived burdensomeness, thwarted belongingness, capability for suicide, and distress., Conclusion: This study is intended to identify potential targets for novel and tailored therapies for people experiencing suicidal ideation and improve targeting of suicide prevention programs. Even modest improvements in current treatments may lead to important reductions in suicide attempts and deaths., Study Registration: Australian New Zealand Clinical Trials Registry identifier: ACTRN12623000433606., (© 2023.

Suicide is the leading cause of death among Australian young people, yet rates of help-seeking for suicidal ideation and behaviors in this population are concerningly low. In this study, the relationships between parental suicide stigma, parental suicide literacy, and their attitudes and intentions toward seeking professional help for their child if they were to express thoughts of suicide are investigated. Understanding this influence is critical given parents are key facilitators of their child's access to and engagement with professional mental health services. An online survey was administered to 302 parents of children aged-12-18 (M age  = 45.36, SD age  = 6.23; 91.4% female). Parental suicide stigma was significantly associated with more negative help-seeking attitudes and lower help-seeking intentions. Other significant predictors of more positive help-seeking attitudes included parental self-efficacy and having a child with no history of suicidal ideation. Higher help-seeking intentions were associated with female gender, living in an urban area, and positive help-seeking attitudes. Parental suicide literacy was not significantly associated with help-seeking. Practically, outcomes of this study may inform the development and implementation of targeted education programs to increase parental help-seeking for their children., (© 2023. The Author(s).)

Background: Child anxiety disorders are highly prevalent yet undertreated. As parents are often 'gatekeepers' to children receiving treatment and support, this study aimed to investigate modifiable parental factors affecting professional help-seeking for their children from general practitioners (GPs), psychologists, and paediatricians., Methods: In this study, 257 Australian parents of children aged 5-12 years with elevated anxiety symptoms completed a cross-sectional online survey. The survey assessed help-seeking from a GP, psychologist, and paediatrician (General Help Seeking Questionnaire), as well as anxiety knowledge (Anxiety Literacy Scale), help-seeking attitudes (Attitudes Toward Seeking Professional Psychological Help), personal stigma (Generalised Anxiety Stigma Scale) and self-efficacy (Self-Efficacy in Seeking Mental Health Care)., Results: 66.9% of participants had sought help from a GP, 61.1% from a psychologist, and 33.9% from a paediatrician. Help-seeking from a GP or psychologist was associated with lower personal stigma (p = .02 and p = .03 respectively). Participants who sought help from a psychologist also had more positive attitudes toward seeking professional support (p = .01). Conversely, knowledge of anxiety disorders and self-efficacy were not associated with help-seeking from any source., Limitations: Limitations of the study include the representativeness of our sample (female gender, higher education level); unexplained variance potentially accounted for by other factors (e.g., structural barriers); lack of prior validation of measures in a parent sample., Conclusions: This research will inform the development of public health policy and psychoeducation interventions for parents, to reduce personal stigma and increase positive attitudes towards professional help-seeking, in turn improving help-seeking for child anxiety., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to declare., (Copyright © 2023 The Authors.

Objectives: The Future Proofing Study (FPS) was established to examine factors associated with the onset and course of mental health conditions during adolescence. This paper describes the design, methods, and baseline characteristics of the FPS cohort., Methods: The FPS is an Australian school-based prospective cohort study with an embedded cluster-randomized controlled trial examining the effects of digital prevention programs on mental health. Data sources include self-report questionnaires, cognitive functioning, linkage to health and education records, and smartphone sensor data. Participants are assessed annually for 5 years., Results: The baseline cohort (N = 6388, M = 13.9 years) is broadly representative of the Australian adolescent population. The clinical profile of participants is comparable to other population estimates. Overall, 15.1% of the cohort met the clinical threshold for depression, 18.6% for anxiety, 31.6% for psychological distress, and 4.9% for suicidal ideation. These rates were significantly higher in adolescents who identified as female, gender diverse, sexuality diverse, or Aboriginal and/or Torres Strait Islander (all ps < 0.05)., Conclusions: This paper provides current and comprehensive data about the status of adolescent mental health in Australia. The FPS cohort is expected to provide significant insights into the risk, protective, and mediating factors associated with development of mental health conditions during adolescence., (© 2022 The Authors.

Background: Social distancing requirements due to the COVID-19 pandemic saw a rapid increase in the delivery of telehealth consultations as an alternative to face-to-face health care services., Objective: The aims of this study were to assess the use and acceptability of telehealth during the early stages of the pandemic and identify factors associated with telehealth avoidance during this period., Methods: Data were obtained from waves 4 and 7 of a longitudinal survey designed to assess the impact of the COVID-19 pandemic on the health and behavior of a representative sample of Australian adults. Participants reported on their use or avoidance of telehealth during the assessment period, as well as the mode of telehealth used and acceptability., Results: Approximately 30% of participants reported using telehealth during the assessment periods, with the most common telehealth modality being the telephone. Acceptance of telehealth was generally high and was higher among those who used telehealth compared with those who did not. Approximately 18% of participants reported avoiding health care due to telehealth. Across assessment waves, avoidance was associated with younger age, speaking a language other than or in addition to English, having a current medical diagnosis, and lower levels of telehealth acceptability., Conclusions: While most participants in this study were accepting of telehealth services, there remain barriers to use, especially among those from particular sociodemographic groups. At a population level, avoidance of health services in nearly one in five adults may have considerable long-term impacts on morbidity and potentially mortality. Targeted efforts to promote engagement with telehealth services are critical if these adverse outcomes are to be avoided, particularly during periods when access to face-to-face services may be limited., (©Louise M Farrer, Philip J Batterham, Amelia Gulliver, Alyssa Morse, Alison L Calear, Sonia McCallum, Michelle Banfield, Yiyun Shou, Eryn Newman, Amy Dawel.

The risk of suicidal behaviour in Australia varies by age, sex, sexual preference and Indigenous status. Suicide stigma is known to affect suicide rates and help-seeking for suicidal crises. The aim of this study was to investigate the sociodemographic correlates of suicide stigma to assist in prevention efforts. We surveyed community members and individuals who had attended specific emergency departments for suicidal crisis. The respondents were part of a large-scale suicide prevention trial in New South Wales, Australia. The data collected included demographic characteristics, measures of help-seeking and suicide stigma. The linear regression analyses conducted sought to identify the factors associated with suicide stigma. The 5426 participants were predominantly female (71.4%) with a mean (SD) age of 41.7 (14.8) years, and 3.9% were Indigenous. Around one-third of participants reported a previous suicide attempt (n = 1690, 31.5%) with two-thirds (n = 3545, 65.3%) seeking help for suicidal crisis in the past year. Higher stigma scores were associated with Indigenous status (β 0.123, 95%CI 0.074-0.172), male sex (β 0.527, 95%CI 0.375-0.626) and regional residence (β 0.079, 95%CI 0.015-0.143). Lower stigma scores were associated with younger age (β -0.002, 95%CI -0.004--0.001), mental illness (β -0.095, 95%CI -0.139 to -0.050), male bisexuality (β -0.202, 95%CI -0.351 to -0.052) and males who glorified suicide (β -0.075, 95%CI -0.119 to -0.031). These results suggested that suicide stigma differed across the community, varying significantly by sex, sexual orientation and Indigenous status. Targeted educational programs to address suicide stigma could assist in suicide prevention efforts.

Background: Suicide plans and attempts rarely occur without prior suicidal ideation but are hard to predict. Early intervention efforts need to focus on subgroups of the population who are more likely to transition from ideation to suicidal plans and attempts. The current study utilised data from a large nationally representative sample to investigate the time taken to transition and the demographic and mental health correlates of transitioning to suicidal plans and attempts among those with suicidal ideation., Methods: Data were from 1237 Australians aged 16-85 years who reported suicidal thoughts at some point in their life. Discrete time survival analysis was used to retrospectively examine the time in years and correlates of transitioning from suicidal ideation to suicide plans and suicide attempt., Results: The majority of those who transitioned to suicide plans or attempts typically did so within 2 years of first experiencing suicidal ideation. Several factors were independently associated with increased speed to transition, including alcohol use disorder, drug use disorder, major depressive episode, obsessive compulsive disorder, sexual minority status, and non-urban location. Older age, being male, older age of first ideation and greater family support were associated with a slower transition., Conclusion: The current study suggests that pre-existing mental or substance use disorders, particularly drug use disorder, as well as sexual minority status, sex and greater family support play an important role in the transition from suicidal ideation to plans or attempts. These results highlight the potential importance of suicide prevention programs that aim to improve social connectedness.

Students transitioning from secondary school to university may experience unique issues that impact their mental health. There is limited research, however, on what drives first year students to seek professional help for mental health problems. There is also a current lack of knowledge about the factors that may be associated with engagement with university life in students transitioning to university, and how engagement may be related to help seeking attitudes and behaviours in a first year university population. Data ( N = 165) were drawn from two waves (Wave 1, February 2021, and Wave 4, June 2021) of a longitudinal study of Australian university students commencing study for the first time, which included measures of engagement, belonging, stigma and help seeking intentions and behaviours. The results showed that students with higher levels of depression stigma prior to commencing university at Wave 1 had less positive attitudes towards help seeking at Wave 4. Students had increased odds of seeking help for a mental health problem in Wave 4 if they had moved away for university, reported higher levels of mental health literacy or willingness to disclose, had lower levels of engagement with university life and were experiencing higher levels of general psychological distress. Students experiencing higher thwarted belongingness were also found to have lower levels of engagement with university at Wave 4. Both thwarted belongingness and stigma were found to be associated with engagement with university and help seeking behaviours and should be examined further.

Objective: The present study examined behavioral responses during the coronavirus disease 2019 (COVID-19) pandemic and the role of dispositional risk tolerance in the Australian context., Method: The study involved a six-wave longitudinal investigation with a nationally representative sample of Australians ( N = 1,296). Dispositional risk tolerance was measured at Wave 1 and participants' anxiety level and self-report implementation of 10 COVID actions was assessed in each wave. Autoregressive multinomial regression models were estimated to assess the unique contribution of risk tolerance to the longitudinal change of participants' implementation of COVID actions., Results: The results revealed a high implementation rate for protective actions when Australia had a peak in the severity of the COVID-19 pandemic and subsequently declined with the easing threat of the pandemic. Individuals' dispositional risk tolerance significantly predicted transition to, and endorsement of, protective actions. Participants who had low risk tolerance were more likely to remain at the state of implementing COVID-19 measures than being in, or transitioning to, other states., Conclusions: The findings suggest that when encouraging protective actions, governments and public authorities should acknowledge variability in the community in responding to risk and consider measures in addition to risk messaging to encourage protective actions among individuals with a high level of risk tolerance.

Background: Suicide is the leading cause of death among young Australians, therefore identifying factors that increase risk is important. The aims of this study was to investigate the association between personality domains and suicidal ideation, plans and attempts in a community-based sample of adolescents., Methods: 1428 students from thirteen secondary schools in Australia completed a survey consisting of demographic information (gender and age), personality risk across four domains (Hopelessness, Impulsivity, Sensation Seeking and Anxiety Sensitivity) as measured by the Substance Use Risk Profile Scale, and psychological distress measured by the Distress Questionnaire 5 scale. Outcome measures included suicidal ideation, plans and attempts measured by the Youth Risk Behavior Survey., Results: Students were aged between 11 and 17 years old (mean: 13.3, SD = 1.2) with 59% identifying as female. Proportions of participants reporting suicidal ideation, plans and at least one attempt were 14%, 9% and 7% respectively. Hopelessness was associated with twice the odds (OR = 3.1 and 2.9) of suicidal thoughts and plans respectively. Hopelessness also had 45% increased odds for suicide attempt (OR = 2.1), however this was not significant in the suicidal ideation sub-group. Impulsivity and sensation seeking were associated with suicidal ideation (OR = 1.3), while only impulsivity was associated with attempt (OR = 1.5)., Limitations: The study was cross-sectional, considered suicidal thoughts and behaviors in past 12 months only and used one measure of personality., Conclusions: Personality traits may be important for determining suicide risk in adolescents. Developing screening and interventions targeting personality may have implications for the detection and prevention of suicide., (Copyright © 2022 Elsevier B.V. All rights reserved.)

Background: The COVID-19 pandemic has resulted in disruptions across many life domains. The distress associated with the pandemic itself, and with public health efforts to manage the outbreak, could result in increased alcohol use. This study aimed to quantify changes in alcohol use during the early stages of the pandemic and factors associated with different patterns of use., Methods: Data were obtained from a longitudinal survey of a representative Australian adult sample (N = 1296, 50% female, M age  = 46.0) conducted from March to June 2020, during the first wave of the COVID-19 outbreak in Australia. Change in alcohol consumption was examined using Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) scores from waves one, three, five, and seven of the study, each 4 weeks apart. Factors associated with alcohol consumption were examined, including depression (PHQ-9) and anxiety (GAD-7) symptoms, health risk tolerance, stress and coping, work and social impairment (WSAS), COVID impacts, and sociodemographic variables. We tested changes in alcohol use across the full sample using a mixed effects repeated measure ANOVA model and a multinomial logistic regression to identify factors assessed at wave 1 that were independently associated with alcohol use., Results: There was no significant change in AUDIT-C scores across the study. For most participants, alcohol use did not increase during the early phase of the COVID-19 pandemic in Australia. COVID-19 exposure, higher perceived coping, depression symptoms, and male gender were associated with greater odds of increasing or elevated levels of alcohol use. Social changes, which included working from home, had mixed effects on alcohol consumption., Conclusions: Although no evidence was found for increased alcohol use overall during the early months of the pandemic, several factors were associated with alcohol consumption at risky levels. Greater understanding of motivations for drinking across public and private contexts, along with targeted support for high-risk groups, could assist in reducing harm associated with alcohol consumption., (© 2022 by the Research Society on Alcoholism.)

Background: The COVID-19 outbreak has spread to almost every country around the world and caused more than 3 million deaths. The pandemic has triggered enormous disruption in people's daily lives with profound impacts globally. This has also been the case in Australia, despite the country's comparative low mortality and physical morbidity due to the virus. This scoping review aims to provide a broad summary of the research activity focused on mental health during the first 10 months of the pandemic in Australia., Results: A search of the Australian literature was conducted between August-November 2020 to capture published scientific papers, online reports and pre-prints, as well as gaps in research activities. The search identified 228 unique records in total. Twelve general population and 30 subpopulation group studies were included in the review., Conclusions: Few studies were able to confidently report changes in mental health driven by the COVID-19 context (at the population or sub-group level) due to a lack of pre-COVID comparative data and non-representative sampling. Never-the-less, in aggregate, the findings show an increase in poor mental health over the early period of 2020. Results suggest that young people, those with pre-existing mental health conditions, and the financially disadvantaged, experienced greater declines in mental health. The need for rapid research appears to have left some groups under-researched (e.g. Culturally and Linguistically Diverse populations and Indigenous peoples were not studied), and some research methods under-employed (e.g. there was a lack of qualitative and mixed-methods studies). There is a need for further reviews as the follow-up results of longitudinal studies emerge and understandings of the impact of the pandemic are refined., (© 2022. The Author(s).)

Background: The uptake of professional mental health services among people with suicidal ideation remains low, yet few community-based studies have characterised modifiable individual barriers to service use. Our aims were (1) to identify factors associated with use of professional mental health services among people experiencing suicidal ideation, and (2) to distinguish subgroups with varying levels of service use., Methods: 1462 Australian adults (78.8% female) were recruited online to participate in a cross-sectional survey. Logistic regression analysis was used to identify factors associated with professional service use. A decision tree model was used to identify subgroups with varying rates of professional service use., Results: Most participants (62%) had used professional services for mental health concerns in the past 12 months. Greater rates of service use were observed in participants who were middle aged, spoke English, disclosed to informal sources or helplines, met criteria for a mental health disorder, had higher levels of entrapment, psychological distress, and disinhibition, and lower levels of detachment and antagonism. At the terminal nodes of the decision tree analysis, service use ranged from 21% to 94%. The most important determinants of service use were meeting criteria for a mental disorder and disclosure of suicidal ideation to family/friends and helplines., Conclusion: These findings suggest that interventions to support the safe disclosure of suicidal ideation may assist in increasing service use. There is also the need for services that meet the needs of individuals who do not meet criteria for a mental health condition., (Copyright © 2022 Elsevier B.V. All rights reserved.)

Background: Self-guided web-based programs are effective; however, inadequate implementation of these programs limits their potential to provide effective and low-cost treatment for common mental health problems at scale. There is a lack of research examining optimal methods for the dissemination of web-based programs in the community., Objective: This study aimed to compare the uptake, reach, relative costs, and adherence associated with 3 community-based pathways for delivering a low-intensity web-based transdiagnostic mental health program. The 3 dissemination pathways were social media advertising, advertising in general practice, and advertising in pharmacies., Methods: Participants were recruited on the web, from general practices, or from community pharmacies; completed a screener for psychological distress; and were offered the 4-week FitMindKit program-a 12-module psychotherapeutic intervention. Uptake was defined as the number of participants who enrolled in the web-based program; reach was defined as the rate of uptake per exposure; and costs were calculated based on staff time, equipment, and advertising. Adherence was assessed as the number of modules of FitMindKit completed by the participants., Results: Uptake comprised 1014 participants who were recruited through the 3 dissemination pathways: on the web (991/1014, 97.73%), in general practice (16/1014, 1.58%), and in pharmacy (7/1014, 0.69%). Reach was highest for social media: 1 in every 50 people exposed to web-based advertising took up the intervention compared with 1 in every 441 in general practitioner clinics and 1 in every 1708 in pharmacies. The dissemination cost was US $4.87 per user on social media, US $557 per user for general practitioner clinics, and US $1272 per user for pharmacy dissemination. No significant differences in adherence were observed between the conditions, whereas all pathways showed an underrepresentation of men and linguistic diversity., Conclusions: The web-based dissemination pathway was the most efficient and cost-effective for delivering a self-guided internet-based mental health program to people in the community. More research is needed to identify how best to engage men and those with culturally diverse backgrounds in web-based interventions., Trial Registration: Australian New Zealand Clinical Trials Registry ACTRN12618001688279; https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=376113., (©Philip J Batterham, Amelia Gulliver, Ella Kurz, Louise M Farrer, Christiaan Vis, Josien Schuurmans, Alison L Calear.

Objective: The direct and indirect mental health impacts of the COVID-19 pandemic are considerable. However, it is unclear how suicidal ideation was affected in communities during the acute lockdown phase of the pandemic, and over the longer-term. This study provides longitudinal data on the prevalence of, and risk factors for, suicidal ideation in the Australian national population, during the pandemic., Method: The Australian National COVID-19 Mental Health and Risk Communication Survey assessed a nationally representative sample of Australian adults (N = 1296) fortnightly for 12 weeks from late-March to June 2020 (7 waves), and again in March 2021 (wave 8). Cox proportional hazards models examined demographic and pandemic-related risk factors for suicidal ideation over time., Results: Prevalence of suicidal ideation was high but steady at ∼18% across the acute lockdown phase of the pandemic, and 16.2% in March 2021. People who had direct experience with COVID-19 (tested, diagnosed, or contact with someone who was diagnosed) had increased risk for suicidal ideation. Higher pandemic-related work and social impairment, recent adversity, loneliness, and being younger were also associated with increased risk of suicidal ideation over time., Conclusion: Both the direct and indirect impacts of COVID-19 were associated with increased risk for suicidal ideation over time, although prevalence did not vary over time. The high prevalence of suicidal ideation in our sample flags a critical need for accessible mental health support, and findings provide insights into the factors placing people at risk during the pandemic., (Copyright © 2022.

The 2019-20 bushfires that raged in eastern Australia were an overwhelming natural disaster leading to lives lost or upended, and communities destroyed. For almost a month, Canberra, Australia's capital city in the Australian Capital Territory (ACT), was obscured by smoke from fires which threatened the outer suburbs. While smoke itself is experientially different from many natural disasters, it nevertheless poses a significant public health threat. As the impact of extended bushfire smoke in an urban setting is relatively unexplored we aimed to capture the individual and community-level experiences of the event and their importance for community and social functioning. We responded rapidly by conducting semi-structured interviews with a range of Canberra residents who, due to their personal or social circumstances, were potentially vulnerable to the effects of the smoke. Three major themes emerging from the narratives depicted disruption to daily life, physical and psychological effects, and shifting social connectedness. This study highlighted the ambiguous yet impactful nature of a bushfire smoke event, and identified four simple key messages that may be critically relevant to policy making in preparation for similar smoke events in the future., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Williamson, Banwell, Calear, LaBond, Leach, Olsen, Walsh, Zulfiqar, Sutherland and Phillips.)

Background: Suicide is a significant public health problem and there is a clear need for interventions to improve help seeking for suicide and psychological distress in young people. This trial aimed to assess the effectiveness of the school-based Sources of Strength program in increasing help-seeking intentions and behaviours in adolescents., Methods: A cluster, randomised controlled trial was conducted in 13 Australian secondary schools (N = 1633), with each school randomly allocated to the intervention (n = 7) or wait-list control condition (n = 6). Participants in the intervention condition received the Sources of Strength program over two years and all participants completed self-report measures of help-seeking intentions and behaviour at four time-points. Staff and students in the intervention condition also provided qualitative feedback on the perceived impact of the program., Results: Mixed model repeated measures analyses demonstrated no significant effect of the Sources of Strength program on help-seeking intentions or behaviour at post-intervention or 6- or 18-month follow-up. Staff and students reported, through qualitative feedback, that the program increased awareness of and openness to help seeking and promoted a common language and school community., Limitations: The current study only included self-report measures that may have been influenced by situational factors or biases., Conclusions: Although the Sources of Strength program may have increased awareness of help seeking, there was no evidence that it is effective in increasing help-seeking intentions or behaviours in this cohort. The program may be more suitable for schools in disadvantaged areas where there may be limited existing connections to trusted adults., (Copyright © 2021 Elsevier B.V. All rights reserved.)

Background: The COVID-19 pandemic has been highly disruptive, with the closure of schools causing sudden shifts for students, educators and parents/caregivers to remote learning from home (home-schooling). Limited research has focused on home-schooling during the COVID-19 pandemic, with most research to date being descriptive in nature. The aim of the current study was to comprehensively quantify the psychosocial impacts of home-schooling on parents and other caregivers, and identify factors associated with better outcomes., Methods: A nationally representative sample of 1,296 Australian adults was recruited at the beginning of Australian COVID-19 restrictions in late-March 2020, and followed up every two weeks. Data for the current study were drawn from waves two and three. Surveys assessed psychosocial outcomes of psychological distress, work and social impairment, and wellbeing, as well as a range of home-schooling factors., Results: Parents and caregivers who were home-schooling during the COVID-19 pandemic experienced significantly higher levels of psychological distress and work/social impairment compared to those who were not home-schooling or had no school-aged children. A current mental health diagnosis or lower levels of perceived support from their child's school negatively affected levels of psychological distress, work and social impairment, and wellbeing in parents and caregivers involved in home-schooling., Conclusions: The mental health impacts of home-schooling were high and may rise as periods of home-schooling increase in frequency and duration. Recognising and acknowledging the challenges of home-schooling is important, and should be included in psychosocial assessments of wellbeing during periods of school closure. Emotional and instrumental support is needed for those involved in home-schooling, as perceived levels of support is associated with improved outcomes. Proactive planning by schools to support parents may promote better outcomes and improved home-schooling experiences for students., (© 2022. The Author(s).)

Background: COVID-19 lockdowns have resulted in school closures worldwide, requiring curriculum to be delivered to children remotely (home schooling). Qualitative evidence is needed to provide important context to the positive and negative impacts of home schooling and inform strategies to support caregivers and children as the pandemic continues. This study aimed to explore the experiences of home schooling caregivers at multiple time-points during the pandemic., Methods: Data were obtained from a longitudinal survey of a representative Australian sample conducted over 8 waves during 2020 and 2021. Participants who had home schooled at least one child during COVID-19 completed open-ended questions at Wave 4 (May 2020; n = 176), Wave 7 (June 2020; n = 145), and Wave 8 (March 2021; n = 57). Participants were asked to describe what they found positive and challenging about home schooling (Wave 4), what they would do differently if they home schooled their children again (Wave 7), and the longer-term impacts of home schooling on caregivers and children (Wave 8)., Results: 91% of participants at Wave 4 reported at least one positive and/or negative aspect of home schooling. At Wave 8, 32% and 29% of participants reported no long-term positive or negative impacts of home schooling respectively. Using a qualitative content analysis approach, six themes were developed from the data, encompassing the impacts of home schooling on parents, and the perceived impacts on children. Impacts on parents included connecting with children, managing the work-life-school balance, and the challenge of home schooling when parents are not teachers. Perceived impacts on children included: quieter and safer learning at home, and the negatives of managing schoolwork load and social isolation. At Wave 7, 56 participants (44%) identified at least one thing they would do differently., Conclusions: Despite some participants reporting positive experiences associated with home schooling, it remains challenging for many parents and their children. Supports for parents and children engaged in home schooling should provide clear and flexible guidance on how to balance schoolwork with other competing demands, assist parents who lack confidence in supporting their children's remote learning, and address risks associated with social isolation., (© 2022.

The 2019-20 bushfire season in south-eastern Australia was one of the most severe in recorded history. Bushfire smoke-related air pollution reached hazardous levels in major metropolitan areas, including the Australian Capital Territory (ACT), for prolonged periods of time. Bushfire smoke directly challenges human health through effects on respiratory and cardiac function, but can also indirectly affect health, wellbeing and quality of life. Few studies have examined the specific health effects of bushfire smoke, separate from direct effects of fire, and looked beyond physical health symptoms to consider effects on mental health and lifestyle in Australian communities. This paper describes an assessment of the health impacts of this prolonged exposure to hazardous levels of bushfire smoke in the ACT and surrounding area during the 2019-20 bushfire season. An online survey captured information on demographics, health (physical and mental health, sleep) and medical advice seeking from 2,084 adult participants (40% male, median age 45 years). Almost all participants (97%) experienced at least one physical health symptom that they attributed to smoke, most commonly eye or throat irritation, and cough. Over half of responders self-reported symptoms of anxiety and/or feeling depressed and approximately half reported poorer sleep. Women reported all symptoms more frequently than men. Participants with existing medical conditions or poorer self-rated health, parents and those directly affected by fire (in either the current or previous fire seasons) also experienced poorer physical, mental health and/or sleep symptoms. Approximately 17% of people sought advice from a medical health practitioner, most commonly a general practitioner, to manage their symptoms. This study demonstrated that prolonged exposure to bushfire smoke can have substantial effects on health. Holistic approaches to understanding, preventing and mitigating the effects of smoke, not just on physical health but on mental health, and the intersection of these, is important. Improved public health messaging is needed to address uncertainty about how individuals can protect their and their families health for future events. This should be informed by identifying subgroups of the population, such as those with existing health conditions, parents, or those directly exposed to fire who may be at a greater risk., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Rodney, Swaminathan, Calear, Christensen, Lal, Lane, Leviston, Reynolds, Trevenar, Vardoulakis and Walker.)

Background: Psychosocial, self-guided, internet-based programs are effective in treating depression and anxiety. However, the community uptake of these programs is poor. Recent approaches to increasing engagement (defined as both uptake and adherence) in internet-based programs include brief engagement facilitation interventions (EFIs). However, these programs require evaluation to assess their efficacy., Objective: The aims of this hybrid implementation effectiveness trial are to examine the effects of a brief internet-based EFI presented before an internet-based cognitive behavioral therapy self-help program (myCompass 2) in improving engagement (uptake and adherence) with that program (primary aim), assess the relative efficacy of the myCompass 2 program, and determine whether greater engagement was associated with improved efficacy (greater reduction in depression or anxiety symptoms) relative to the control (secondary aim)., Methods: A 3-arm randomized controlled trial (N=849; recruited via social media) assessed the independent efficacy of the EFI and myCompass 2. The myCompass 2 program was delivered with or without the EFI; both conditions were compared with an attention control condition. The EFI comprised brief (5 minutes), tailored audio-visual content on a series of click-through linear webpages., Results: Uptake was high in all groups; 82.8% (703/849) of participants clicked through the intervention following the pretest survey. However, the difference in uptake between the EFI + myCompass 2 condition (234/280, 83.6%) and the myCompass 2 alone condition (222/285, 77.9%) was not significant (n=565; χ 2 1 =29.2; P=.09). In addition, there was no significant difference in the proportion of participants who started any number of modules (1-14 modules) versus those who started none between the EFI + myCompass 2 (214/565, 37.9%) and the myCompass 2 alone (210/565, 37.2%) conditions (n=565; χ 2 1 <0.1; P=.87). Finally, there was no significant difference between the EFI + myCompass 2 and the myCompass 2 alone conditions in the number of modules started (U=39366.50; z=-0.32; P=.75) or completed (U=39494.0; z=-0.29; P=.77). The myCompass 2 program was not found to be efficacious over time for symptoms of depression (F 4,349.97 =1.16; P=.33) or anxiety (F 4,445.99 =0.12; P=.98). However, planned contrasts suggested that myCompass 2 may have been effective for participants with elevated generalized anxiety disorder symptoms (F 4,332.80 =3.50; P=.01)., Conclusions: This brief internet-based EFI did not increase the uptake of or adherence to an existing internet-based program for depression and anxiety. Individuals' motivation to initiate and complete internet-based self-guided interventions is complex and remains a significant challenge for self-guided interventions., Trial Registration: Australian New Zealand Clinical Trials Registry ACTRN12618001565235; https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=375839., (©Philip J Batterham, Alison L Calear, Matthew Sunderland, Frances Kay-Lambkin, Louise M Farrer, Helen Christensen, Amelia Gulliver.

Objectives: To estimate initial levels of symptoms of depression and anxiety, and their changes during the early months of the COVID-19 pandemic in Australia; to identify trajectories of symptoms of depression and anxiety; to identify factors associated with these trajectories., Design, Setting, Participants: Longitudinal cohort study; seven fortnightly online surveys of a representative sample of 1296 Australian adults from the beginning of COVID-19-related restrictions in late March 2020 to mid-June 2020., Main Outcome Measures: Symptoms of depression and anxiety, measured with the Patient Health Questionnaire (PHQ-9) depression and Generalised Anxiety Disorder (GAD-7) scales; trajectories of symptom change., Results: Younger age, being female, greater COVID-19-related work and social impairment, COVID-19-related financial distress, having a neurological or mental illness diagnosis, and recent adversity were each significantly associated with higher baseline depression and anxiety scores. Growth mixture models identified three latent trajectories for depression symptoms (low throughout the study, 81% of participants; moderate throughout the study, 10%; initially severe then declining, 9%) and four for anxiety symptoms (low throughout the study, 77%; initially moderate then increasing, 10%; initially moderate then declining, 5%; initially mild then increasing before again declining, 8%). Factors statistically associated with not having a low symptom trajectory included mental disorder diagnoses, COVID-19-related financial distress and social and work impairment, and bushfire exposure., Conclusion: Our longitudinal data enabled identification of distinct symptom trajectories during the first three months of the COVID-19 pandemic in Australia. Early intervention to ensure that vulnerable people are clinically and socially supported during a pandemic should be a priority., (© 2021 AMPCo Pty Ltd.)

Background: The interpersonal-psychological theory of suicidal behavior (IPTS) posits that the joint presence of perceived burdensomeness (PB), thwarted belongingness (TB), and capability for suicide (CS) is necessary for suicide attempt. Emerging evidence demonstrates these effects are not consistently observed. Psychopathology may independently impact on the explanatory power of the IPTS constructs., Aims: The aims of the current study were to assess whether the inclusion of psychopathology indicators into the IPTS explains additional variance in recent suicide attempt and to assess the relative influence of interpersonal-psychological constructs versus mental illness on suicide attempt., Method: Australian adults (N = 1,323; 77% female) who reported suicidal ideation in the past year were recruited using social media advertising to complete an online cross-sectional survey., Results: None of the predicted IPTS interactions was significantly associated with recent suicide attempt, although PB and CS had significant independent associations. The addition of psychopathology indicators to the IPTS model explained significant additional variation in suicide attempt (18% vs. 14%)., Conclusions: The influence of psychopathology on suicide attempt may be insufficiently explained by interpersonal-psychological constructs. The IPTS may have greater explanatory power to identify transitions from suicidal ideation to suicide attempt after accounting for mental illness., (© 2020 The American Association of Suicidology.)

Objective: To assess associations between physical, mental, and social well-being and suicide and self-harm in a community-based sample of older adults., Methods: Using a cohort design, questionnaire data from 102,880 individuals aged 65 years or older living in New South Wales, Australia during 2006-2009 were linked to hospital and cause-of-death databases until 2017. Poisson regressions obtained adjusted incidence rate ratios (IRRs)., Results: One hundred nine suicides and 191 deliberate self-harm (DSH) events occurred. Compared to those reporting excellent/good overall health, older adults reporting fair overall health had higher suicide rates (IRR = 2.8, 95% confidence interval: 1.8-4.4). Also, suffering from physical limitations was associated with higher rates of suicide. A fair versus excellent/good memory was associated with higher rates of suicide (IRR = 2.0, 1.3-3.3). Male erectile dysfunction was linked to self-harm (IRR = 2.8, 1.0-7.7). Suicide rates were elevated with baseline Kessler-10 scores of 20-50 versus 10-15 (IRR = 5.0, 2.9-8.9); the corresponding IRR for DSH was 2.9 (1.8-4.8). Elevated rates were observed for both self-reported depression and anxiety. Poor versus excellent/good quality of life was associated with suicide (IRR = 4.3, 1.7-10.7) and achieving less than desired to due to emotional problems was linked to self-harm (IRR = 1.8 1.3-2.4). Rates of suicide ande DSH were lower in those with ≥5 people to depend on versus one (suicide: IRR = 0.5, 0.3-0.9; DSH: IRR = 0.5, 0.3-0.7)., Conclusions: Older adults experiencing health problems, including those relating to overall health or memory, and those with psychological distress had elevated rates of suicidal behavior. Rates of subsequent self-harm and/or death by suicide were elevated in participants with small social networks., (© 2020 John Wiley & Sons Ltd.)

Objective: To test the effectiveness of a male-targeted upstream public health intervention in increasing help-seeking intentions for mental disorders and suicide in an adolescent population., Method: A two-arm controlled trial was conducted with 10 schools in the Australian Capital Territory. A total of 594 male adolescents aged between 16 and 18 years participated in the study. Participants in the intervention condition received the single session Silence is Deadly program, while participants in the control condition completed usual classes. All participants completed a pre-intervention, post-intervention, and a 6- to 12-week follow-up survey assessing help-seeking intentions, attitudes, and behaviors., Results: At follow-up, the Silence is Deadly program was found to significantly increase help-seeking intentions from friends, which was in line with the program's messaging to seek help from and provide support to friends in times of distress or suicide risk. The program did not have an effect on help-seeking intentions for other sources of help or on help-seeking attitudes and behavior., Conclusions: The present study provides preliminary support for male-targeted public health interventions for suicide that use male-focused norming and role modeling to improve help-seeking in this population., (© 2020 American Association of Suicidology.)

Objective: Previous research suggests that sleep disturbance is associated with suicidal ideation and suicide attempt. However, few studies have accounted for the presence of multiple mental disorders and interpersonal factors associated with suicide risk. Furthermore, limited research has examined which aspects of sleep disturbance are most strongly associated with suicidal thoughts and attempts., Method: A large community-based sample of Australian adults (n = 3,618; 81% female; 37% reporting ideation) completed a comprehensive survey assessing suicidal thoughts and behaviours, sleep disturbance, common mental disorders and interpersonal risk factors. Sleep disturbance was assessed using the 6-item PROMIS sleep disturbance scale and suicidality was measured using the Psychiatric Symptom Frequency Scale. Analyses were adjusted for age, sex, perceived burdensomeness, thwarted belongingness, and clinical caseness for six mental disorders, including major depression., Results: After accounting for mental health, demographic and interpersonal characteristics, increasing sleep disturbance was significantly associated with higher odds of both suicidal ideation (OR=1.17 for one-SD increase in PROMIS-SD), and suicide attempt (OR=1.33 for one-SD increase in PROMIS-SD). Of the specific indicators of sleep disturbance, only sleep onset (difficulties falling asleep) had a significant independent association with both suicidal ideation (p < 0.001) and suicide attempt (p = 0.047)., Conclusions: Sleep disturbance is independently associated with greater risk of suicidal thoughts and behaviours. Sleep disturbance is highly modifiable, so sleep interventions for people with suicide risk and sleep problems may provide an effective and efficient approach to suicide prevention in the community., (Copyright © 2020.

Purpose: The aim of this study was to examine the relation of mental, physical, and social wellbeing measures to death by suicide and self-harm (SH)., Methods: Using a cohort design, questionnaire data on 266,324 responders aged ≥ 45 years, living in NSW, Australia were linked to hospital and death databases during 2006-2017. Adjusted incidence rate ratios (IRR) were calculated., Results: Overall, 212 suicides and 723 SH episodes were observed. A dose-response relationship with suicidal behaviour was found for Kessler-10 Psychological Distress Scale; IRRs of 4.5 (95% CI 2.4-8.3) for suicide and 8.3 (95% CI 6.5-10.7) for SH were observed for scores of high versus low distress. Elevated rates were also observed for those reporting poor versus good or excellent health (suicide, IRR: 3.8, 95% CI 2.2-6.9; SH, IRR: 4.5 95% CI 3.4-6.1); being dependent versus not dependent on help with daily tasks (suicide, IRR: 2.4 95% CI 1.5-3.7; SH, IRR: 2.6 95% CI 2.0-3.3); being a current smoker (suicide, IRR: 1.8, 95% CI 1.1-2.9; SH, IRR: 2.9 95% CI 2.3-3.5) having versus not having male erectile problems (SH, IRR: 1.9 95% CI 1.4-2.5). Participants with ≥ 5 people versus one person to depend on had reduced suicidal behaviour (suicide, IRR: 0.5 95% CI 0.3-0.7, SH, IRR: 0.5 95% CI 0.4-0.6)., Conclusions: An active social network was linked to lower rates of suicide and self-harm. Adverse health, dependence on help, psychological distress were associated with higher rates of suicide and self-harm, while erectile problems were linked to an elevated rate of self-harm.

Background: It is well established that racism is a fundamental contributor to poor health and inequities. There is consistent evidence of high exposure to discrimination among Aboriginal and Torres Strait Islander (Indigenous Australian) peoples, but impacts have not been fully quantified, in part due to limited measurement tools. We aim to validate instruments developed to measure interpersonal discrimination., Methods: Instruments were discussed at five focus groups and with experts, and field tested in developing Mayi Kuwayu: The National Study of Aboriginal and Torres Strait Islander Wellbeing. Data from 7501 baseline survey participants were analysed. Acceptability was assessed according to extent of missingness, construct validity using exploratory and confirmatory factor analysis, and reliability using Cronbach's alpha. Associations between each instrument and outcomes conceptually understood to be closely (community-level racism) or less closely (family wellbeing) related were quantified to test convergent and discriminant validity., Results: An 8-item instrument captures experiences of discrimination in everyday life and a 4-item instrument experiences in healthcare, each followed by a global attribution item. Item missingness was 2.2-3.7%. Half (55.4%) of participants reported experiencing any everyday discrimination, with 65.7% attributing the discrimination to Indigeneity; healthcare discrimination figures were 34.1% and 51.1%. Items were consistent with two distinct instruments, differentiating respondents with varying experiences of discrimination. Scales demonstrated very good reliability and convergent and divergent validity., Conclusion: These brief instruments demonstrate face validity and robust psychometric properties in measuring Aboriginal and Torres Strait Islander adults' experiences of interpersonal discrimination in everyday life and in healthcare. They can be used to quantify population-level experiences of discrimination, and associated wellbeing consequences, and monitor change.

Objective: Few measures have been developed to assess the efficacy of community-based suicide prevention and recovery services. The current study aimed to develop a scale to provide accurate assessment and monitoring of functional recovery for people following a recent suicide attempt at The Way Back Support Service in Australia., Method: The study was conducted in multiple iterative stages: (1) literature review to identify existing scales; (2) structured informant interview with people with lived experience of a suicide attempt; (3) expert survey of researchers, clinicians, and people with lived experience on relevance and acceptability of candidate items; and (4) quantitative survey of the pilot scale to assess psychometric properties., Results: An 11-item scale assessing recovery in people who have recently attempted suicide was demonstrated to be a unidimensional measure with sound psychometric properties (α = 0.94). The scale was highly acceptable to researchers, clinicians, and people with lived experience. A short-form 6-item scale was also developed., Conclusions: The Functioning and Recovery Scale is likely to be useful for evaluating suicide prevention programs. No existing scale captures the broad construct of psychosocial functioning with sound psychometric rigor and the involvement of people with lived experience of suicide attempt., (© 2020 The American Association of Suicidology.)

Objectives: The current study aimed to investigate the psychometric properties of the DSM-5 dimensional severity scales for social anxiety disorder (SAD) and panic disorder (PD) using a past 30 day timeframe., Methods: Data were from a sample of 1,052 Australian community dwelling adults (aged 18 years or older) recruited using online advertisements. Respondents completed the DSM-5 severity scales for SAD and PD as well as a range of additional widely used self-administered scales for SAD and PD in the past 30 days prior to the survey., Results: Both scales exhibited high internal consistency (alpha>=0.94) and a strong general factor that justified unidimensional item response analysis (OmegaH=0.96). There was no evidence of significant local dependence amongst item pairs after accounting for the single factor. Similarly, there was no evidence for meaningful differential item functioning of the scales across sex, age, education level, and residential location. There was high convergent validity (0.71 - 0.85) amongst conceptually related scale and moderate to high correlations (0.54 - 0.80) between conceptually unrelated scales., Conclusions: These findings provide support for the use of past month versions of the DSM-5 severity scales for SAD and PD by researchers and clinicians to inform and supplement diagnostic decisions., Competing Interests: Declaration of Competing Interest The authors wish to declare no conflict of interest including financial and personal relationships with other people or organisations that could inappropriate influence this work., (Copyright © 2020 Elsevier B.V.

Introduction: For individuals presenting to the emergency department (ED) for a suicide attempt, the period after discharge from hospital is marked by heightened vulnerability for further suicide attempts. Effective care following a suicidal crisis has the potential to significantly decrease this risk. The current study aims to examine the impact of the LifeSpan multilevel suicide prevention model on experiences of care following a suicidal crisis. Perspectives from healthcare consumers (individuals who have presented to the ED following a suicidal crisis), carers, and health professionals will be explored. The LifeSpan model is currently being evaluated as a high-fidelity trial in four geographically defined regions in New South Wales, Australia., Methods and Analysis: This study will use a mixed methods prospective cohort design. Quantitative data collection includes a structured survey, administered to healthcare consumers from LifeSpan sites and control sites. Two cohorts of healthcare consumers will be recruited 12 months apart with baseline assessment occurring within 18 months of the ED presentation, and follow-up 12 months after the initial assessment. Survey participants will be recruited online and through participating EDs, mental health organisations and aftercare services. Qualitative interview data from healthcare consumers, carers who have accompanied a loved one to the ED following a suicidal crisis and health professionals who provide care to people at risk of suicide will be collected concurrently with the recruitment of the first cohort of survey participants. Purposive and convenience sampling techniques will be used for recruitment of interview participants. The primary outcome for this study will be healthcare consumers' experiences of service provided at the ED. Analysis will be undertaken of the change over time within LifeSpan sites, as well as between LifeSpan sites and control sites, using mixed effects repeated measures models as principal means of data analysis., Ethics and Dissemination: This research has been approved by the Hunter New England Human Research Ethics Committee (HREC/17/HNE/144). Results will be disseminated via conferences and peer-reviewed journals., Trial Registration Number: ACTRN12617000457347., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Background: This study evaluated the acceptability and effectiveness of a relationship-focussed mobile phone application (WeClick) for improving depressive symptoms and other mental health outcomes in adolescents., Methods: A randomised controlled trial involving 193 youth (M age: 14.82, SD: 0.94, 86.5% female) from Australia was conducted. Youth were recruited via the Internet and randomly allocated to the intervention or a 4-week wait list control condition, stratified for age and gender. The primary outcome was change in depressive symptom scores measured using the Patient Health Questionnaire for Adolescents (PHQ-A) at baseline, 4-week post-test and 12-week follow-up. Secondary outcomes included anxiety, psychological distress, wellbeing, help-seeking intentions for mental health, social self-efficacy and social support. Participants in the intervention condition received access to the intervention for four weeks. Thematic analysis was utilised to identify and examine acceptability., Results: The change in PHQ-A scores from baseline to 4-week post-test did not differ significantly (d = 0.26, p = .138) between the intervention (Mchange = -2.9, SD = 5.3) and wait list control conditions (Mchange = -1.7, SD = 4.3). However, significant between-group improvements were observed in wellbeing (d = 0.37, p = .023), help-seeking intentions (d = 0.36, p = .016) and professional help-seeking intentions for mental health problems (d = 0.36, p = .008). Increases in help-seeking intentions were sustained at follow-up in the intervention condition. No differential effects were found for generalised anxiety, separation anxiety, social self-efficacy or for any social support outcomes. Over 90% of participants indicated the app was enjoyable, interesting and easy to use. The app provided 'advice and direction' (n = 42; 46.15%), an 'opportunity for self-reflection' (n = 33; 36.3%) and 'normalised experiences' (n = 21; 23.1%)., Conclusions: The WeClick app was found to be effective for improving wellbeing and help-seeking intentions for mental health in adolescents. A larger, adequately powered trial is now required to establish differential effects on depressive symptoms. This trial was registered with the Australian New Zealand Clinical Trials Registry (ANZCTR): ACTRN12618001982202., (© 2020 The Authors.

Background: People who are at elevated risk of suicide stand to benefit from internet-based interventions; however, research in this area is likely impacted by a range of ethical and practical challenges. The aim of this study was to examine the ethical issues and practical barriers associated with clinical studies of internet-based interventions for suicide prevention., Method: This was a mixed-methods study involving two phases. First, a systematic search was conducted to identify studies evaluating internet-based interventions for people at risk of suicide, and information pertaining to safety protocols and exclusion criteria was extracted. Second, investigators on the included studies were invited to complete an online survey comprising open-ended and forced-choice responses. Quantitative and qualitative methods were used to analyse the data., Results: The literature search identified 18 eligible studies, of which three excluded participants based on severity of suicide risk. Half of the 15 suicide researchers who participated in the survey had experienced problems obtaining ethics approval, and none had encountered adverse events attributed to their intervention. Survey respondents noted the difficulty of managing risk in online environments and the limitations associated with implementing safety protocols, although some also reported increased confidence resulting from the ethical review process. Respondents recommended researchers pursue a collaborative relationship with their research ethics committees., Conclusion: There is a balance to be achieved between the need to minimise the risk of adverse events whilst also ensuring interventions are being validated on populations who may be most likely to use and benefit from them (i.e., those who prefer anonymity). Further research is required to obtain the views of research ethics committees and research participants on these issues. Dialogue between researchers and ethics committees is necessary to address the need to ensure safety while also advancing the timely development of effective interventions in this critical area.

Background: Despite increasing investment in suicide prevention, Australian suicide rates have increased steadily in the past decade. In response to growing evidence for multicomponent intervention models for reducing suicide, the LifeSpan model has been developed as the first multicomponent, evidence-based, system-wide approach to suicide prevention in Australia. The LifeSpan model consists of nine evidence-based strategies. These include indicated, selective and universal interventions which are delivered simultaneously to community and healthcare systems over a 2-year implementation period. This study will evaluate the effectiveness of the LifeSpan model in reducing suicide attempts and suicide deaths in four geographically defined regions in New South Wales, Australia., Methods: We outline the protocol for a stepped-wedge, cluster randomized controlled trial. Following a 6-month transition phase, the trial sites will move to the 2-year active implementation phase in 4-monthly intervals with evaluation extending a minimum of 24 months after establishment of the full active period. Analysis will be undertaken of the change attributable to the invention across the four sites. The primary outcome for the study is the rate of attempted suicide in the regions involved. Rate of suicide deaths within each site is a secondary outcome., Discussion: If proven effective, the LifeSpan model for suicide prevention could be more widely delivered in Australian communities, providing a valuable new approach to tackle rising suicide rates. LifeSpan has the potential to significantly contribute to the mental health of Australians by improving help-seeking for suicide, facilitating early detection, and improving aftercare to reduce re-attempts. The findings from this research should also contribute to the evidence base for multilevel suicide prevention programs internationally., Trial Registration: Australia New Zealand Clinical Trials Register, ID: ACTRN12617000457347.

The current study developed and examined the performance of a computerized adaptive version of the Social Interaction Anxiety and Social Phobia Scales (SIAS/SPS) and compared results with a previously developed static short form (SIAS-6/SPS-6) in terms of measurement precision, concordance with the full forms, and sensitivity to treatment. Among an online sample of Australian adults, there were relatively minor differences in the performance of the adaptive tests and static short forms when compared with the full scales. Moreover, both adaptive and static short forms generated similar effect sizes across treatment in a clinical sample. This provides further evidence for the use of static or adaptive short forms of the SIAS/SPS rather than the lengthier 20-item versions. However, at the individual level, the adaptive tests were able to maintain an acceptable level of precision, using few items as possible, across the severity continua in contrast to the static short forms.

Background: Limited research has been conducted to quantify the level of disability and health related quality of life (HRQoL) associated with suicidal thoughts and behaviour. The aims of the current study were to (1) describe levels of disability and HRQoL in an Australian sample of adults with suicidal ideation, (2) examine the effect of zero, one, or more than one previous suicide attempt on disability and HRQoL, and (3) describe the demographic and clinical characteristics associated with disability and HRQoL., Method: Data for the current study is drawn from the baseline assessment of the Healthy Thinking trial that evaluated the effectiveness of an online self-help program for suicidal thoughts in an Australian adult community sample (n = 418). Measures of disability, quality of life, clinical symptoms, suicidality and demographic variables were included., Results: The mean disability score for the overall sample was 19.2 (SD = =8.9), while the mean perceived physical health score was 40.7 (SD = =6.5) and the mean perceived mental health score was 36.1 (SD = =5.9). Higher levels of disability and lower levels of perceived physical health were associated with multiple suicide attempts compared to one or no history of suicide attempt., Limitations: Limitations included the limited generalisability of results, the use of self-report to assess suicide attempts, and the use of cross-sectional data., Conclusion: Suicidal thoughts and behaviours are associated with high levels disability and low levels of perceived physical and mental health. Early intervention programs are needed to reduce the high levels of burden associated with suicidality., Competing Interests: Declaration of Competing Interest BvS and HC are authors of the web-based self-help program mentioned in this manuscript.

Objective: The aim of the current study was to use a 23-item bank of self-reported symptoms of suicidal thoughts and behaviors to develop new brief measures of suicide risk using data-driven methods. Collectively referred to as the Rapid Measurement Toolkit for Suicidality (RMTS), the new brief static and adaptive measures would allow more efficient screening for suicide risk in clinical and research settings., Method: Data for the current study consist of 3,175 Australian adults who form the development sample and 3,755 Australian adults who form the validation sample. Both samples were independently recruited online using Facebook advertisements. Item response theory (IRT) was applied to the 23-item suicide item bank to develop a brief static dimensional measure and to simulate various computerized adaptive algorithms., Results: A 5-item brief static dimensional screener was developed, which performed as well as the commonly used Suicidal Behaviors Questionnaire-Revised (SBQ-R), with marginally greater sensitivity and more information across the continuum of suicidality. An adaptive screener required a mean of 6.2 items and correlated 0.98 with the full item bank., Conclusions: The RMTS provides reliable and valid brief static and adaptive screeners for the measurement of suicide risk in community, research, and clinical settings., (© 2019 The American Association of Suicidology.)
