Research on climate anxiety is rapidly growing, with ongoing exploration of population prevalence, contributing factors, and mitigation strategies that transform anxiety into helpful action. What remains unclear is whether and how to delineate climate anxiety from mental ill health. A limited conceptualization of climate anxiety restricts efforts to identify and support those adversely affected. This paper draws on psychological and existential theories to propose a theoretical model of climate anxiety and coping, extending previous conceptualizations. The model theorizes that climate change evokes an existential conflict that manifests affectively as climate anxiety (and other emotional experiences), wherein cognitive and behavioral coping processes are activated. These processes fall on a continuum of adaptivity, depending on functional impact. Responses might range from meaningful engagement with activities that address climate change to maladaptive strategies that negatively impact personal, social, and occupational functioning. Applications of this model in research and practice are proposed. [ABSTRACT FROM AUTHOR]

Introduction: The 10-item Kessler Psychological Distress Scale (K10) is used to screen adolescents for mental disorders in Australian clinical practice; however, there are no Australian adolescent normative data. Methods: Data were drawn from a nationally representative sample (N = 2964) of Australian adolescents (11–17 years). This study had three aims: (1) to examine concurrent validity between the K10 and Strengths and Difficulties Questionnaire (SDQ) emotional symptoms subscale, (2) to establish normative Australian adolescent K10 data and (3) to determine optimal K10 cut-off scores for screening for major depressive disorder (MDD) via receiver operator characteristic curve analysis and stratum-specific likelihood ratios. Results: The K10 and SDQ emotional symptoms scales were moderately correlated (rs = 0.63, p < 0.001). Older female adolescents reported higher total K10 scores compared with younger female adolescents (15–17 years: M = 20.2, standard error [SE] = 0.3; 11–14 years: M = 16.8, SE = 0.3) and male adolescents (11–14 years: M = 16.6, SE = 0.2; 15–17 years: M = 16.0, SE = 0.2). K10 scores to optimally discriminate those with and without MDD varied by age and sex and had low specificities. Stratum-specific likelihood ratios indicated adolescents with a K10 score of ≥ 30 will have a 12.9 (95% confidence interval = [10.2, 16.2]) increased likelihood of MDD. Conclusion: The K10 has utility for assessing psychological distress in health care and epidemiological research in Australian adolescents. Adolescents with K10 scores in the 'very high' range are at increased risk of MDD. Further assessment of these young people is indicated to identify those with or at risk of developing MDD.

Objective: Differences between adolescent self-reported and parent-reported emotional and behavioural difficulties may influence psychiatric epidemiological research. This study examined concordance between adolescents and their parents about mental health symptoms using the Strengths and Difficulties Questionnaire. Methods: The study comprised a randomly selected, nationally representative sample of adolescents aged 11–17 years who participated in the Second Australian Child and Adolescent Survey of Mental Health and Wellbeing (N = 2967). Matched adolescent and parent responses across the five Strengths and Difficulties Questionnaire subscales (emotional problems, hyperactivity, peer problems, conduct problems and prosocial behaviour), as well as total difficulties and total impact scores were examined to estimate concordance. Concordance patterns were analysed by sex, after stratifying the sample by age group (younger adolescents: 11–14 years; older adolescents: 15–17 years). Results: Concordance was 86.7% for total difficulties, 77.5% for total impact and ranged from 82.4% to 94.3% across the five Strengths and Difficulties Questionnaire subscales. There were no differences in concordance between sexes on the total difficulties score. Older females were more likely to disagree with their parents about emotional problems compared to males of the same age. Younger males were more likely to disagree with their parents compared to same-aged females about peer problems, hyperactivity, conduct problems and prosocial skills, as well as the impact of their problems. Older males were more likely to disagree with their parents about their prosocial skills compared to older females. Conclusion: Overall, concordance between adolescents and parents on the Strengths and Difficulties Questionnaire was largely driven by the high proportion of respondents who reported having no problems. Discordance on a subscale increased as the prevalence of problems in a sex and age demographic subgroup increased. These findings highlight the need for a multi-informant approach to detect emotional and behavioural difficulties in adolescents, particularly when assessing the impact of symptoms, as this subscale had the lowest concordance.

This study examined rates of mental health disorders and health risk behaviors in people with diverse gender identities and associations with five types of child maltreatment. We used data from the Australian Child Maltreatment Study (ACMS), a nationally representative survey of Australian residents aged 16 years and more, which was designed to understand the experience of child maltreatment (physical abuse, sexual abuse, emotional abuse, neglect, exposure to domestic violence). Mental disorders—major depressive disorder, generalized anxiety disorder (GAD), alcohol use disorder, post-traumatic stress disorder (PTSD), and health risk behaviors—smoking, binge drinking, cannabis dependence, self-harm, and suicide attempt in the past 12 months were assessed. People with diverse gender identities who experienced child maltreatment were significantly more likely to have GAD (43.3%; 95% CI [30.3, 56.2]) than those who had experienced child maltreatment who were either cisgender men (13.8%; [12.0, 15.5]) or cisgender women (17.4%; [15.7, 19.2]). Similarly, higher prevalence was found for PTSD (21.3%; [11.1, 31.5]), self-harm (27.8%; [17.1, 38.5]) and suicide attempt (7.2%; [3.1, 11.3]) for people with diverse gender identities. Trauma-informed approaches, attuned to the high likelihood of any child maltreatment, and the co-occurrence of different kinds may benefit people with diverse gender identities experiencing GAD, PTSD, self-harm, suicidal behaviors, or other health risk behaviors.

This study presents the most comprehensive national prevalence estimates of diverse gender and sexuality identities in Australians, and the associations with five separate types of child maltreatment and their overlap (multi-type maltreatment). Using Australian Child Maltreatment Study (ACMS) data ( N = 8503), 9.5% of participants identified with a diverse sexuality and .9% with a diverse gender. Diverse identities were more prevalent in the youth cohort, with 17.7% of 16-24 years olds identifying with a diverse sexuality and 2.3% with a diverse gender. Gender and sexuality diversity also intersect - for example, with women (aged 16-24 and 25-44) more likely than men to identify as bisexual. The prevalence of physical abuse, sexual abuse, emotional abuse, neglect and exposure to domestic violence was very high for those with diverse sexuality and/or gender identities. Maltreatment was most prevalent for participants in the youth cohort with diverse gender identities (90.5% experiencing some form of child maltreatment; 77% multi-type maltreatment) or diverse sexualities (85.3% reporting any child maltreatment; 64.3% multi-type maltreatment). The strong association found between child maltreatment and diverse sexuality and gender identities is critical for understanding the social and mental health vulnerabilities of these groups, and informing services needed to support them., 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.

This study compared differences in cardiovascular (CV) risk factor responses between males and females following endurance (END) and resistance (RES) training. We present the frequency of responders to each training modality and the magnitude of response. Using a randomized crossover design, 68 healthy adults [age: female (F): 24.5 ± 4.6; male (M): 27.3 ± 6.6] completed 3 mo of RES and END, with 3 mo washout. Peak oxygen consumption (V̇o 2peak ), strength, body composition, blood pressure, glucose, insulin, and lipids were measured. V̇o 2peak (L/min) significantly increased in both sexes following END, but not RES. The magnitude of change was larger in males (F: +0.20 L/min; M: +0.32 L/min), although this did not achieve statistical significance ( P = 0.051). Strength significantly increased in both sexes following RES ( P < 0.01), with a larger increase in males (Leg press: F: +39 kg; M: +63 kg; P < 0.05). Lean mass significantly increased in both sexes ( P < 0.01) following RES and fat mass decreased in females following END ( P = 0.019). The change in C-reactive protein following END was significantly different between sexes (F: -0.4 mg/L; M: +0.5 mg/L; P = 0.035). There were no differences between sexes in the proportion of individuals who responded positively to any variable following RES or END; differences between sexes were due to the magnitude of change. Males had a larger increase in V̇o 2peak following END and strength following RES. There were no sex differences in other CV risk factors. This suggests differences in physiological responses to strength and V̇o 2peak may not translate to changes in CV risk in healthy subjects. NEW & NOTEWORTHY This study investigated sex differences in cardiovascular risk factors in response to different exercise training modalities. Males had a larger improvement in peak oxygen consumption following endurance training and strength following resistance training compared with females. These changes in peak oxygen consumption and strength did not translate to changes in other cardiovascular risk factors. Despite the greater magnitude of change in males, there were no sex differences in the proportion of individuals who responded to training.

Purpose: No previous study has described sex differences in chronic cardiac adaptation in response to distinct modalities of exercise training in humans., Methods: Cardiac magnetic resonance imaging (1.5 T) was used to assess left ventricular (LV) outcomes in 78 untrained subjects (46F, 26 M; 26.1 ± 5.4 yr). Subjects underwent 3 months of closely supervised and monitored resistance (RES) and endurance (END) training, separated by a 3-month washout period., Results: LV mass (LVM) increased in response to END in both sexes (females △3.98 ± 7.98 g, P = 0.002; males △5.99 ± 10.67 g, P = 0.005), whereas LV end-diastolic volume (EDV) increased in males (△7.48 ± 11.91 mL, P = 0.002) but not females (△1.54 ± 10.49 mL, P = 0.373). In response to RES, LVM and EDV did not increase in either sex. The proportion of subjects exhibiting a positive response to training (i.e., a change >0) for LVM and EDV did not differ between sexes for either training modality., Conclusion: Eccentric hypertrophy in response to END training was more apparent in males than females, whereas there were no notable cardiac changes between sexes for RES training. The proportion of low versus high responders to training was not sex specific for LVM or EDV in response to either commonly prescribed exercise training modality., (Copyright © 2021 by the American College of Sports Medicine.)
