Background: Adolescence is a critical period for preventing substance use and mental health concerns, often targeted through separate school-based programs. However, co-occurrence is common and is related to worse outcomes. This study explores prevention effects of leading school-based prevention programs on co-occurring alcohol use and psychological distress. Methods: Data from two Australian cluster randomized trials involving 8576 students in 97 schools were harmonized for analysis. Students received either health education (control) or one of five prevention programs (e.g. Climate Schools, PreVenture) with assessments at baseline and 6, 12, 24, and 30 or 36 months (from ages ~13–16). Multilevel multinomial regressions were used to predict the relative risk ratios (RRs) of students reporting co-occurring early alcohol use and psychological distress, alcohol use only, distress only, or neither (reference) across programs. Results: The combined Climate Schools: Alcohol and Cannabis and Climate Schools: Mental Health courses (CSC) as well as the PreVenture program reduced the risk of adolescents reporting co-occurring alcohol use and psychological distress (36 months RRCSC = 0.37; RRPreVenture = 0.22). Other evaluated programs (excluding Climate Schools: Mental Health) only appeared effective for reducing the risk of alcohol use that occurred without distress. Conclusions: Evidence-based programs exist that reduce the risk of early alcohol use with and without co-occurring psychological distress, though preventing psychological distress alone requires further exploration. Prevention programs appear to have different effects depending on whether alcohol use and distress present on their own or together, thus suggesting the need for tailored prevention strategies.

BackgroundHigh rates of cannabis and illicit drug use are experienced by young people during the final stages of neurodevelopment (aged 15-24 years), a period characterized by high neuroplasticity. Frequent drug use during this time may interfere with neurophysiological and neuropsychological development pathways, potentially leading to ongoing unfavorable neuroadaptations. The dose-response relationship between illicit drug use, exposure, and individual neurodevelopmental variation is unknown but salient with global shifts in the legal landscape and increasingly liberal attitudes and perceptions of the harm caused by cannabis and illicit drugs. ObjectiveThis systematic review aims to synthesize longitudinal studies that investigate the effects of illicit drug use on structural, functional, and cognitive brain domains in individuals under the neural age of adulthood (25 years). This protocol outlines prospective methods that will facilitate an exhaustive review of the literature exploring pre- and post-drug use brain abnormalities arising during neurodevelopment. MethodsFive electronic databases (Medline, Embase, PsycINFO, ProQuest Central, and Web of Science) will be systematically searched between 1990 and 2019. The search terms will be a combination of MeSH (Medical Subject Headings), with keywords adapted to each database. Study reporting will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and if relevant, study quality will be assessed using the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) approach. Eligible studies are those that sampled youth exposed to cannabis or illicit drugs and employed neurophysiological or neuropsychological assessment techniques. Studies will be excluded if participants had been clinically diagnosed with any psychiatric, neurological, or pharmacological condition. ResultsThis is an ongoing review. As of February 2020, papers are in full-text screening, with results predicted to be complete by July 2020. ConclusionsIntegrating data collected on the three brain domains will enable an assessment of the links between structural, functional, and cognitive brain health across individuals and may support the early detection and prevention of neurodevelopmental harm.

BackgroundDespite evidence of increasing harms and community concern related to the drug crystal methamphetamine (“ice”), there is a lack of easily accessible, evidence-based information for community members affected by its use, and to date, no evidence-based mobile apps have specifically focused on crystal methamphetamine. ObjectiveThis study aims to describe the co-design and beta testing of a mobile app to provide evidence-based, up-to-date information about crystal methamphetamine to the general community. MethodsA mobile app about crystal methamphetamine was developed in 2017. The development process involved multiple stakeholders (n=12), including technology and drug and alcohol experts, researchers, app developers, a consumer expert with lived experience, and community members. Beta testing was conducted with Australian general community members (n=34), largely recruited by the Web through Facebook advertising. Participants were invited to use a beta version of the app and provide feedback about the content, visual appeal, usability, engagement, features, and functions. In addition, participants were asked about their perceptions of the app’s influence on awareness, understanding, and help-seeking behavior related to crystal methamphetamine, and about their knowledge about crystal methamphetamine before and after using the app. ResultsThe vast majority of participants reported the app was likely to increase awareness and understanding and encourage help-seeking. The app received positive ratings overall and was well received. Specifically, participants responded positively to the high-quality information provided, usability, and visual appeal. Areas suggested for improvement included reducing the amount of text, increasing engagement, removing a profile picture, and improving navigation through the addition of a “back” button. Suggested improvements were incorporated prior to the app’s public release. App use was associated with an increase in perceived knowledge about crystal methamphetamine; however, this result was not statistically significant. ConclusionsThe Cracks in the Ice mobile app provides evidence-based information about the drug crystal methamphetamine for the general community. The app is regularly updated, available via the Web and offline, and was developed in collaboration with experts and end users. Initial results indicate that it is easy to use and acceptable to the target group.

BackgroundAmid considerable community concern about the prevalence and harms associated with the use of crystal methamphetamine (“ice”), the increased use of smartphones to access health information and a growing number of available smartphone apps related to crystal methamphetamine, no previous reviews have examined the content and quality of these apps. ObjectiveThis study aims to systematically review existing apps in the iTunes and Google Play Stores to determine the existence, composition, and quality of educational smartphone apps about methamphetamines, including ice. MethodsThe iTunes and Google Play Stores were systematically searched in April 2017 for iOS Apple and Android apps, respectively. English-language apps that provided educational content or information about methamphetamine were eligible for inclusion. Eligible apps were downloaded and independently evaluated for quality by 2 reviewers using the Mobile Application Rating Scale (MARS). ResultsA total of 2205 apps were initially identified, of which 18 were eligible and rated using the MARS. The mean MARS quality total score for all rated apps was 3.0 (SD 0.6), indicating poor to acceptable quality. Overall, mean scores were the highest for functionality (mean 4.0, SD 0.5) and lowest for engagement (mean 2.3, SD 0.7). ConclusionsThis study demonstrates a shortage of high-quality educational and engaging smartphone apps specifically related to methamphetamine. The findings from this review highlight a need for further development of engaging and evidence-based apps that provide educational information about crystal methamphetamine.

Objective: Rising rates of mental illness in young people over recent decades are a trend that represents a wake-up call across the globe. The causes of this increase are not known. We also know little about effective interventions or implementation strategies to prevent depression in either youth or adults. The need for the prevention of mental ill health represents an outstanding research opportunity for our field., Method: This conceptual article identifies current challenges in our field, provides potential solutions, and suggests the most promising avenues for future solutions and how we might investigate them., Results: Key challenges include the following: poor implementation with low fidelity; methodological challenges related to appropriate sampling, time frames, interventions, and active controls; and lack of fit between interventions and their context. Potential solutions include the following: supplementing trials with evidence from large-scale epidemiological studies, establishing prevention models that work at scale including those that address social determinants and show effectiveness in low- and middle-income countries, building capacity in methods, and strengthening geographically dispersed networks of prevention researchers and practitioners., Conclusions: There are major challenges in conducting prevention research and demonstrating effects. New perspectives and collaborations are needed to overcome existing barriers. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Aims: Prompt initial contact with a treatment provider is a critical first step in seeking help for a mental or substance use disorders (SUDs). The aim of the current study was to provide estimates of patterns and predictors of delay in making initial treatment contact based on the recently completed Australian National Survey of Mental Health and Wellbeing., Methods: Data came a nationally representative epidemiological survey of n = 15,893 Australians. Measures included DSM-IV lifetime diagnoses of mood (MD), anxiety (AD) and SUDs; age of disorder onset; and age of first treatment contact. Correlates of treatment delay were examined., Results: SUDs exhibited the lowest lifetime treatment rate (27%), compared to MD (94%) and ADs (85%). Individuals with AD experienced the longest delay in seeking treatment (Mdn = 11 years), followed by those with SUDs (Mdn = 8 years) and MDs (Mdn = 3 years). Females had higher odds of seeking treatment for MD and AD but lower odds for SUDs. Recent birth cohorts showed increased treatment seeking across disorders, and higher education was associated with increased treatment seeking for MD and AD. Age of onset, country of birth and co-occurring disorders had mixed associations with treatment seeking., Conclusions: The study reveals stark disparities in treatment-seeking behaviour and delays across mental and substance use disorders, with a pronounced underutilization of services for SUDs. Additionally, attention should be directed towards early intervention for individuals with earlier symptom onset, those from earlier cohorts and those with co-occurring SUDs.

In this article, we evaluate the current state of universal school-based mental health prevention. We argue that the field is at another pivotal turning point, with many unanswered questions. As youth mental health issues rise in prominence and prevalence, schools increasingly adopt mental health and well-being programmes. However, recent large-scale trials have reported varied effects, raising questions about their effectiveness. We critically analyse these findings and place them in a global context. We contend results in high-income countries should not be seen as a failure of universal prevention overall and unpack key learnings from trials that have not found significant preventive effects. A comprehensive perspective of the data reveals both negative and positive aspects, as well as some signposts for the way forward. We advocate for programme adaptation based on feedback, embracing proportionate universalism and exploring alternative prevention strategies without discarding universal prevention. We urge continued research with stakeholder involvement, emphasising a nuanced approach to universal school-based mental health prevention, is urgently needed to move the field forward., (© 2025 The Author(s).

Background: Preventure is a selective school-based personality-targeted program that has shown long-term benefits in preventing student alcohol use, internalising and externalising problems when delivered by psychologists. In this first Australian randomised controlled trial of school staff implementation of Preventure, we aimed to examine i) acceptability, feasibility, and fidelity and ii) effectiveness of Preventure on student alcohol use, internalising, and externalising symptoms., Methods: A cluster-randomised controlled implementation trial was conducted in Sydney, Australia and was guided by the RE-AIM framework (Glasgow et al. 1999); which measures reach, effectiveness, adoption, implementation, and maintenance. Schools were randomly assigned to either the Preventure intervention or active control (health education as usual). Nominated school staff from intervention schools received training and delivered the program to students with elevated scores on one of four personality types targeted in the program. School staff completed surveys on RE-AIM measures, which were analysed using descriptive statistics and thematic analysis. Students completed surveys at baseline and six months post-intervention; mixed-effects regression examined intervention by time interactions on alcohol use, internalising and externalising problems, at six-month follow-up. The study was prospectively registered with the Australian New Zealand Clinical Trials Registry (ACTRN12620000790943, registration date 6 August 2020)., Results: 553 students across 8 schools participated in the baseline survey. Of these, 40% had elevated scores on one of the four personality profiles, resulting in 220 students in the current study (102 students in intervention schools, 118 students in control schools; mean age 13.6, 45.7% female). Most RE-AIM domains showed high ratings, with school staff showing good adherence and confidence in delivery. However, teachers reported difficulties with feasibility, particularly a lack of time. Student outcomes: There were significant improvements in depression and conduct problems across both intervention and control across time. There were no significant main or interaction effects of the intervention on student alcohol use, internalising, or externalising problems., Discussion: Teachers and students rated the program highly. However, concerns around feasibility may limit teacher-led application of the program in the Australian context. Alternative approaches, such as delivery by dedicated personnel within schools without a teaching load, may be critical in implementing such evidence-based interventions at scale., Trial Registration: The study was prospectively registered with the Australian New Zealand Clinical Trials Registry, registration number: ACTRN12620000790943, registration date: 6 August 2020., Competing Interests: Declarations. Ethics approval and consent to participate: In accordance with the Declaration of Helsinki and Australian National Statement on Ethical Conduct in Human Research, ethical approval was obtained from the University of Sydney Human Research Ethics Committee (2019/792), and the approval body for New South Wales (NSW) public (state) schools (State Education Research Applications Process).

Issue Addressed: Substance use and mental illness remain critical issues for young Australians, however, engagement with evidence-based health resources is challenging among this age group. This study aimed to develop engaging, useful digital health resources, underpinned by neuroscience principles, to build awareness of the harms of electronic cigarettes (e-cigarettes) and concurrent alcohol and antidepressant use., Methods: A mixed-methods approach was adopted to co-design two evidence-based videos resources. The resources were co-designed with the Matilda Centre's Youth Advisory Board Centre's Youth Advisory Board through a series focus groups and individual feedback reviews. Young people residing in New South Wales were then invited to complete a survey to evaluate the usefulness, relatability and impact on perceived harms associated with each substance pre- and post-viewing resources., Results: A total of 100 participants completed the survey (mean age = 21.5 years, SD = 2.77, 42% Female, 2% Non-binary). The animated videos were well received, with the large majority (91% and 87% respectively) of participants rating them 'excellent' or 'very good'. After viewing the videos, there was a significant increase in the perception of harm associated with e-cigarette use, monthly (t(99) = 2.76, p = .003), weekly (t(99) = 4.82, p < .001) and daily (t(99) = 4.92, p < .001), and consuming alcohol whilst taking antidepressants both weekly (t(100) = 2.93, p = .004) and daily (t(100) = 3.13, p = .002)., Conclusions: This study describes a successful co-design process demonstrating how meaningful involvement of young people, alongside traditional research methods, can produce substance use prevention resources that are useful, engaging and increase knowledge of harms among young people. SO WHAT?: To achieve meaningful public health impact researchers, experts and digital creators can work together to co-create substance use educational materials that are engaging, well-liked, while imparting important health knowledge., (© 2024 The Author(s).

Introduction: Barriers to help-seeking for illicit drug use cross psychosocial (e.g., knowledge of where to seek help, attitudinal beliefs like being afraid of what people will think) and structural (e.g., service availability) domains. Along with people who use illicit drugs, it is important to consider the perspectives of other key groups who are often involved in the help-seeking and recovery process. This study aimed to examine the perceived barriers to help-seeking for people who use crystal methamphetamine ('ice') among key groups (people who use crystal methamphetamine, families and friends, health workers) as well as the general community., Methods: A cross-sectional online survey open to all Australian residents (aged ≥18 years) was conducted November 2018-March 2019. Four key groups of interest were recruited to examine and compare perceived barriers to help-seeking for crystal methamphetamine use., Results: Participants (n = 2108) included: people who use/have used crystal methamphetamine (n = 564, 39%), health workers (n = 288, 26.8%), affected family/friends (n = 434, 13.7%) and general community (n = 822, 20.6%). People who used crystal methamphetamine demonstrated increased odds of reporting attitudinal (OR 1.35; 1.02-1.80) or structural (OR 1.89; 1.09-3.27) barriers, or a previous negative help-seeking experience (OR 2.27; 1.41-3.66) compared to knowledge barriers. Health workers demonstrated decreased odds of reporting attitudinal compared to knowledge barriers (OR 0.69; 0.50-0.95)., Discussion and Conclusions: Perceived barriers to seeking help for crystal methamphetamine use differed among key groups involved in treatment and recovery. Acknowledging and addressing the mismatches between key groups, through targeted interventions may better support people to seek help for crystal methamphetamine use., (© 2024 The Author(s).

Background: Mental disorders are the leading cause of disease burden among youth. Effective prevention of mental disorders during adolescence is a critical public health strategy to reduce both individual and societal harms. Schools are an important setting for prevention; however, existing universal school-based mental health interventions have shown null, and occasionally iatrogenic, effects in preventing symptoms of common disorders, such as depression and anxiety., Objective: This study aims to report the adaptation process of an established, universal, school-based prevention program for depression and anxiety, OurFutures Mental Health. Using a 4-stage process; triangulating quantitative, qualitative, and evidence syntheses; and centering the voices of young people, the revised program is trauma-informed; lesbian, gay, bisexual, transgender, nonbinary, queer, questioning, and otherwise gender and sexuality diverse (LGBTQA+) affirmative; relevant to contemporary youth; and designed to tailor intervention dosage to those who need it most (proportionate universalism)., Methods: Program adaptation occurred from April 2022 to July 2023 and involved 4 stages. Stage 1 comprised mixed methods analysis of student evaluation data (n=762; mean age 13.5, SD 0.62 y), collected immediately after delivering the OurFutures Mental Health program in a previous trial. Stage 2 consisted of 3 focus groups with high school students (n=39); regular meetings with a purpose-built, 8-member LGBTQA+ youth advisory committee; and 2 individual semistructured, in-depth interviews with LGBTQA+ young people via Zoom (Zoom Video Communications) or WhatsApp (Meta) text message. Stage 3 involved a clinical psychologist providing an in-depth review of all program materials with the view of enhancing readability, improving utility, and normalizing emotions while retaining key cognitive behavioral therapy elements. Finally, stage 4 involved fortnightly consultations among researchers and clinicians on the intervention adaptation, drawing on the latest evidence from existing literature in school-based prevention interventions, trauma-informed practice, and adolescent mental health., Results: Drawing on feedback from youth, clinical psychologists, and expert youth mental health researchers, sourced from stages 1 to 4, a series of adaptations were made to the storylines, characters, and delivery of therapeutic content contained in the weekly manualized program content, classroom activities, and weekly student and teacher lesson summaries., Conclusions: The updated OurFutures Mental Health program is a trauma-informed, LBGTQA+ affirmative program aligned with the principles of proportionate universalism. The program adaptation responds to recent mixed findings on universal school-based mental health prevention programs, which include null, small beneficial, and small iatrogenic effects. The efficacy of the refined OurFutures Mental Health program is currently being tested through a cluster randomized controlled trial with up to 1400 students in 14 schools across Australia. It is hoped that the refined program will advance the current stalemate in universal school-based prevention of common mental disorders and ultimately improve the mental health and well-being of young people in schools., (©Lucinda Grummitt, Sasha Bailey, Erin V Kelly, Louise Birrell, Lauren A Gardner, Jillian Halladay, Cath Chapman, Jack L Andrews, Katrina E Champion, Emily Hunter, Lyra Egan, Chloe Conroy, Raaya Tiko, An Nguyen, Maree Teesson, Nicola C Newton, Emma L Barrett.

Objective: Being a mother of a young child may be protective against alcohol misuse for some, but not all, women. This is the first study to identify the mental health and psychosocial correlates of alcohol misuse among postpartum mothers., Method: Mothers with a child younger than 12 months ( n = 319) were recruited via social media to complete a cross-sectional online survey. Two hierarchical logistic regressions examined unique factors associated with heavy episodic drinking and hazardous alcohol use, including sociodemographic, poor mental health, and psychosocial factors., Results: On average, mothers drank alcohol at low levels (4 drinking days, nine standard drinks in the past month). One in 10 (11.6%) reported heavy episodic drinking during this time, and 1 in 12 (8.5%) were drinking at hazardous or greater levels. In the final models, older age and more severe postpartum anxiety were associated with a higher likelihood of hazardous drinking (odds ratio [OR] = 1.37, 1.09, respectively), whereas breastfeeding was associated with lower odds of heavy episodic drinking (OR = 0.29). Greater perceived social support was associated with lower odds of heavy episodic (OR = 0.56) and hazardous (OR = 0.39) drinking, whereas higher coping-with-anxiety and social-drinking motives were associated with greater odds of both forms of alcohol misuse (ORs = 3.51-10.40). Conformity drinking motives (e.g., drinking to avoid social rejection) were negatively associated with heavy episodic drinking (OR = 0.24)., Conclusions: Maternal anxiety, coping-with-anxiety and social-drinking motives, and reduced social support are important factors associated with postpartum alcohol misuse. These modifiable factors are potential targets for screening and intervention for mothers who may need additional support and preventative care., Competing Interests: The authors have no conflicts of interest to declare.

Background: The CSC study found that the universal delivery of a school-based, online programme for the prevention of mental health and substance use disorders among adolescents resulted in improvements in mental health and substance use outcomes at 30-month follow-up. We aimed to compare the long-term effects of four interventions-Climate Schools Combined (CSC) mental health and substance use, Climate Schools Substance Use (CSSU) alone, Climate Schools Mental Health (CSMH) alone, and standard health education-on mental health and substance use outcomes among adolescents at 72-month follow-up into early adulthood., Methods: This long-term study followed up adolescents from a multicentre, cluster-randomised trial conducted across three states in Australia (New South Wales, Queensland, and Western Australia) enrolled between Sept 1, 2013, and Feb 28, 2014, for up to 72 months after baseline assessment. Adolescents (aged 18-20 years) from the original CSC study who accepted contact at 30-month follow-up and provided informed consent at 60-month follow-up were eligible. The interventions were delivered in school classrooms through an online delivery format and used a mixture of peer cartoon storyboards and classroom activities that were focused on alcohol, cannabis, anxiety, and depression. Participants took part in two web-based assessments at 60-month and 72-month follow-up. Primary outcomes were alcohol use, cannabis use, anxiety, and depression, measured by self-reported surveys and analysed by intention to treat (ie, in all students who were eligible at baseline). This trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12613000723785), including the extended follow-up study., Findings: Of 6386 students enrolled from 71 schools, 1556 (24·4%) were randomly assigned to education as usual, 1739 (27·2%) to CSSU, 1594 (25·0%) to CSMH, and 1497 (23·4%) to CSC. 311 (22·2%) of 1401 participants in the control group, 394 (26·4%) of 1495 in the CSSU group, 477 (37·%) of 1289 in the CSMH group, and 400 (32·5%) of 1232 in the CSC group completed follow-up at 72 months. Adolescents in the CSC group reported slower year-by-year increases in weekly alcohol use (odds ratio 0·78 [95% CI 0·66-0·92]; p=0·0028) and heavy episodic drinking (0·69 [0·58-0·81]; p<0·0001) than did the control group. However, significant baseline differences between groups for drinking outcomes, and no difference in the predicted probability of weekly or heavy episodic drinking between groups were observed at 72 months. Sensitivity analyses increased uncertainty around estimates. No significant long-term differences were observed in relation to alcohol use disorder, cannabis use, cannabis use disorder, anxiety, or depression. No adverse events were reported during the trial., Interpretation: We found some evidence that a universal online programme for the prevention of anxiety, depression, and substance use delivered in early adolescence is effective in reducing the use and harmful use of alcohol into early adulthood. However, confidence in these findings is reduced due to baseline differences, and we did not see a difference in the predicted probability of drinking between groups at 72-month follow-up. These findings suggest that a universal prevention programme in adolescence is not sufficient to have lasting effects on mental health and substance use disorders in the long term. In addition to baseline differences, substantial attrition warrants caution in interpretation and the latter factor highlights the need for future long-term follow-up studies to invest in strategies to increase engagement., Funding: Australian National Health and Medical Research Council., Competing Interests: Declaration of interests MT and NCN are two of the developers of the OurFutures programmes (formerly Climate Schools) and are members of the OurFutures Institute, a not-for-profit charity that distributes the OurFutures programmes to maximise social wellbeing.

Aims: The aim of this study was to measure the effectiveness of an on-line, neuroscience-based harm reduction intervention (The Illicit Project) on substance use, harms and knowledge over a 12-month period., Design: We used a two-arm cluster-randomized controlled trial., Setting: The study was conducted at eight secondary schools across New South Wales, Australia., Participants: A total of 950 (mean age = 15.9; standard deviation = 0.68) in grades 10-12 at participating schools in 2020 took part., Intervention and Comparator: The Illicit Project intervention group (schools = five, n = 681) received an on-line, universal substance use and harm reduction programme over three classes. The active control group (schools = three, n = 269) received school-based health education as usual., Measurements: Self-report questionnaires assessed primary [alcohol, nicotine, cannabis, 3,4-methylenedioxymethamphetamine (MDMA), cocaine and prescription drug misuse] and secondary outcomes (alcohol-related harms and drug literacy) at baseline and the 6- and 12-month follow-up assessment., Findings: Approximately 63% (n = 595) of the sample completed the 12-month follow-up assessment, including 58% of the intervention group (n = 396/679) and 66% of the active control group (n = 179/271). Participants in the intervention group had slower annual increases in binge drinking [odds ratio (OR) = 0.33, 95% confidence interval (CI) = 0.12-0.89], nicotine use (OR = 0.80, 95% CI = 0.52-1.23), MDMA use (OR = 0.14, 95% CI = 0.02-1.00), cocaine use (OR = 0.06, 95% CI = 0.01-0.64) and prescription drug misuse (OR = 0.07, 95% CI = 0.01-0.54) compared with the active control group. There was limited evidence of an intervention effect on cannabis use and alcohol-related harm (P > 0.5). The secondary outcomes showed that the intervention group maintained higher levels of drug literacy knowledge (β = 3.71, 95% CI = 1.86-5.56) and harm reduction help-seeking skills (β = 1.55, 95% CI = 0.62-2.48) compared with the active control group., Conclusion: The Illicit Project (an on-line, neuroscience-based substance use harm reduction intervention) was effective in slowing the uptake of risky substance use and improving drug literacy skills among late secondary school students in Australia, compared with school-based health education as usual., (© 2023 The Authors.

Background: This review evaluated the existing literature exploring the effects of arts-inclusive programs (AIPs) on the mental health and wellbeing of young children. AIPs include activities, programs, or interventions containing creative arts., Methods: Literature searches were conducted across three databases (SCOPUS, psycINFO, and ERIC). The search was restricted to studies reporting outcomes of children 0-6 years., Results: Nine studies were included in the review (3,671 participants). Three key themes were identified: music-related ( n  = 4); artmaking ( n  = 3); and storytelling/drama ( n  = 2). All included studies reported positive outcomes on children's wellbeing following engagement in AIPs., Discussion: This review found emerging evidence demonstrating positive impacts of arts engagement on the wellbeing of children aged 0-6. However, most studies were low quality and used varying outcome measures. The review is one of the first to highlight the lack of high-quality studies on the relationship between AIPs and wellbeing in young children.

Background: The use of generative artificial intelligence, more specifically large language models (LLMs), is proliferating, and as such, it is vital to consider both the value and potential harms of its use in medical education. Their efficiency in a variety of writing styles makes LLMs, such as ChatGPT, attractive for tailoring educational materials. However, this technology can feature biases and misinformation, which can be particularly harmful in medical education settings, such as mental health and substance use education. This viewpoint investigates if ChatGPT is sufficient for 2 common health education functions in the field of mental health and substance use: (1) answering users' direct queries and (2) aiding in the development of quality consumer educational health materials., Objective: This viewpoint includes a case study to provide insight into the accessibility, biases, and quality of ChatGPT's query responses and educational health materials. We aim to provide guidance for the general public and health educators wishing to utilize LLMs., Methods: We collected real world queries from 2 large-scale mental health and substance use portals and engineered a variety of prompts to use on GPT-4 Pro with the Bing BETA internet browsing plug-in. The outputs were evaluated with tools from the Sydney Health Literacy Lab to determine the accessibility, the adherence to Mindframe communication guidelines to identify biases, and author assessments on quality, including tailoring to audiences, duty of care disclaimers, and evidence-based internet references., Results: GPT-4's outputs had good face validity, but upon detailed analysis were substandard in comparison to expert-developed materials. Without engineered prompting, the reading level, adherence to communication guidelines, and use of evidence-based websites were poor. Therefore, all outputs still required cautious human editing and oversight., Conclusions: GPT-4 is currently not reliable enough for direct-consumer queries, but educators and researchers can use it for creating educational materials with caution. Materials created with LLMs should disclose the use of generative artificial intelligence and be evaluated on their efficacy with the target audience., (©Sophia Spallek, Louise Birrell, Stephanie Kershaw, Emma Krogh Devine, Louise Thornton.

Background: Although it is well known that adolescents frequently turn to their friends for support around mental health and substance use problems, there are currently no evidence-based digital programs to support them to do this., Objective: The aim of this study was to evaluate the efficacy of the Mind your Mate program, a digital peer-support program, in improving mental health symptoms, reducing the uptake of substance use, and increasing help seeking. The Mind your Mate program consists of a 40-minute web-based classroom lesson and a companion smartphone mobile app. The active control group received school-based health education as usual., Methods: A cluster randomized controlled trial was conducted with 12 secondary schools and 166 students (mean age 15.3, SD 0.41 years; 72/166, 43.4% female; and 133/166, 80.1% born in Australia). Participants completed self-reported questionnaires assessing symptoms of mental health (depression, anxiety, and psychological distress), substance use (alcohol and other drug use), and help-seeking measures at baseline and at 6-month and 12-month follow-ups., Results: Students who received the Mind your Mate program had greater reductions in depressive symptoms over a 12-month period than controls (b=-1.86, 95% CI -3.73 to 0.02; Cohen d=-0.31). Anxiety symptoms decreased among students in the intervention group; however, these reductions did not meet statistical significance thresholds. No differences were observed in relation to psychological distress or help-seeking., Conclusions: Small to moderate reductions in depression symptoms were observed among students allocated to receive the Mind your Mate intervention. Although the current results are encouraging, there is a need to continue to refine, develop, and evaluate innovative applied approaches for the prevention of mental disorders in real-world settings., Trial Registration: Australian New Zealand Clinical Trials Registry (ANZCTR) ACTRN12620000753954; https://anzctr.org.au/Trial/Registration/TrialReview.aspx?ACTRN=12620000753954., International Registered Report Identifier (irrid): RR2-10.2196/26796., (©Louise Birrell, Jennifer Debenham, Ainsley Furneaux-Bate, Katrina Prior, Sophia Spallek, Louise Thornton, Catherine Chapman, Nicola Newton.

Background: Lifetime trajectories of mental ill-health are often established during adolescence. Effective interventions to prevent the emergence of mental health problems are needed. In the current study we assessed the efficacy of the cognitive behavioural therapy (CBT)-informed Climate Schools universal eHealth preventive mental health programme, relative to a control. We also explored whether the intervention had differential effects on students with varying degrees of social connectedness., Method: We evaluated the efficacy of the Climate Schools mental health programme (19 participating schools; average age at baseline was 13.6) v. a control group (18 participating schools; average age at baseline was 13.5) which formed part of a large cluster randomised controlled trial in Australian schools. Measures of internalising problems, depression and anxiety were collected at baseline, immediately following the intervention and at 6-, 12- and 18-months post intervention. Immediately following the intervention, 2539 students provided data on at least one outcome of interest (2065 students at 18 months post intervention)., Results: Compared to controls, we found evidence that the standalone mental health intervention improved knowledge of mental health, however there was no evidence that the intervention improved other mental health outcomes, relative to a control. Student's social connectedness did not influence intervention outcomes., Conclusion: These results are consistent with recent findings that universal school-based, CBT-informed, preventive interventions for mental health have limited efficacy in improving symptoms of anxiety and depression when delivered alone. We highlight the potential for combined intervention approaches, and more targeted interventions, to better improve mental health outcomes.

Background: Physical inactivity is a preventable risk factor for several chronic diseases and one of the driving forces behind the growing global burden of disease. Recent evidence has shown that interventions using mobile smartphone apps can promote a significant increase in physical activity (PA) levels. However, the accuracy and reliability of using apps is unknown., Objective: The aim of our review was to determine the accuracy and reliability of using mobile apps to measure PA levels in young people. We conducted a systematic review guided by PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)., Methods: Studies published from 2007 to 2020 were sourced from 8 databases-Ovid MEDLINE, Embase (Elsevier), Cochrane Library (Wiley), PsychINFO (EBSCOhost), CINAHL (EBSCOhost), Web of Science (Clarivate), SPORTDiscus (EBSCOhost), and IEEE Xplore Digital Library database. Studies were conducted in young people aged 10-24 years and without chronic illnesses, who evaluated a mobile app's ability to measure PA. Primary outcomes included validity, reliability, and responsiveness of the measurement approach. Duplicate screening was conducted for eligibility, data extraction, and assessing the risk of bias. Results were reported as a systematic review. The main physical activity measures evaluated for each study were the following: total PA time (min/day or min/week), total moderate to vigorous PA per week, daily step count, intensity measure (heart rate), and frequency measure (days per week)., Results: Of the 149 identified studies, 5 met the inclusion criteria (322 participants, 176 female; mean age 14, SD 3 years). A total of 3 studies measured criterion validity and compared PA measured via apps against PA measured via an Actigraph accelerometer. The 2 studies that reported on construct validity identified a significant difference between self-reported PA and the objective measure. Only 1 of the 5 apps examined was available to the public, and although this app was highly accepted by young people, the app recorded PA to be significantly different to participants' self-reported PA., Conclusions: Overall, few studies assess the reliability, validity, and responsiveness of mobile apps to measure PA in healthy young people, with studies typically only reporting on one measurement property. Of the 3 studies that measured validity, all concluded that mobile phones were acceptable and valid tools. More research is needed into the validity and reliability of smartphone apps to measure PA levels in this population as well as in populations with other characteristics, including other age groups and those with chronic diseases., Trial Registration: PROSPERO CRD42019122242; https://www.crd.york.ac.uk/prospero/display&#95;record.php?RecordID=122242., (©Belinda Parmenter, Claire Burley, Courtney Stewart, Jesse Whife, Katrina Champion, Bridie Osman, Nicola Newton, Olivia Green, Annie B Wescott, Lauren A Gardner, Rachel Visontay, Louise Birrell, Zachary Bryant, Cath Chapman, David R Lubans, Matthew Sunderland, Tim Slade, Louise Thornton.

Background: Digital technologies and mobile interventions are possible tools for prevention initiatives to target the substantial social and economic impacts that anxiety, mood, and substance use disorders have on young people., Objective: This paper described the design and development of the Mind your Mate program, a smartphone app and introductory classroom lesson enhancing peer support around the topics of anxiety, depression, and substance use for adolescents., Methods: The development of Mind your Mate was an iterative process conducted in collaboration with adolescents (n=23), experts, school staff, and software developers. The development process consisted of 3 stages: scoping; end-user consultations, including a web-based survey and 2 focus groups with 23 adolescents (mean age 15.9, SD 0.6 years); and app development and beta-testing., Results: This process resulted in a smartphone peer support app and introductory classroom lesson aimed at empowering adolescents to access evidence-based information and tools to better support peers regarding mental health and substance use-related issues. The program contains links to external support services and encourages adolescents to reach out for help if they are concerned about themselves or a friend., Conclusions: The Mind your Mate program was developed in collaboration with a number of key stakeholders in youth mental health, including adolescents. The resulting program has the potential to be taken to scale to aid prevention efforts for youth mental health and substance use. The next step is to conduct a randomized controlled trial testing the feasibility, acceptability, and efficacy of the program., (©Louise Birrell, Ainsley Furneaux-Bate, Jennifer Debenham, Sophia Spallek, Nicola Newton, Catherine Chapman.
