Multilevel risk and protective factors for self-harm, suicidal ideation and suicide attempt in adolescents / Alison L. CALEAR in Journal of Child Psychology and Psychiatry, 67-5 (May 2026)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 67-5 (May 2026) . - p.609-619 Titre : Multilevel risk and protective factors for self-harm, suicidal ideation and suicide attempt in adolescents Type de document : texte imprimé Auteurs : Alison L. CALEAR, Auteur ; Philip J. BATTERHAM, Auteur ; Aliza WERNER-SEIDLER, Auteur ; Kate MASTON, Auteur ; Michelle TOROK, Auteur ; Bridianne O'DEA, Auteur ; Mark E. LARSEN, Auteur ; Helen CHRISTENSEN, Auteur Article en page(s) : p.609-619 Langues : Anglais (eng) Mots-clés : Suicide  self-harm  adolescent  risk factors  protective factors Index. décimale : PER Périodiques Résumé : Background Better characterising risk and protective factors for suicidal distress and self-harm in adolescents may facilitate better targeting of interventions that address underlying vulnerabilities. However, few previous longitudinal studies have: (1) sufficient power to identify key risk and protective factors, (2) limited representativeness to the community and (3) accounted for multilevel factors (individual, family, community). This study aimed to assess prevalence and identify risk and protective factors for self-harm, suicidal ideation and suicide attempts in a large cohort of Australian adolescents. Methods Data from 4,122 adolescents from 134 Australian schools were collected as part of the Future Proofing Study, a prospective cohort study of adolescent mental health and wellbeing. Generalised linear mixed models were used to assess the effect of baseline mental health, lifestyle, social and school-level factors on self-harm, suicidal ideation and suicide attempt at 12-month follow-up. Results At 12-month follow-up, 17.7% of adolescents reported self-harming behaviour, 18.6% reported suicidal ideation and 3.0% reported a suicide attempt. In addition to mental health history, female and gender-diverse identities, LGBTQA+ identity and greater levels of prosocial behaviour were significantly associated with self-harm and suicidal ideation. Peer problems were associated with suicidal ideation and suicide attempt. Conclusions Rates of suicidal distress and self-harm remain high in Australian adolescents. Reducing symptoms of depression, improving peer relationships, mitigating online bullying and providing social support for families may be suitable targets for future prevention and early intervention programs.

A randomised controlled trial of a relationship-focussed mobile phone application for improving adolescents' mental health / Bridianne O'DEA in Journal of Child Psychology and Psychiatry, 61-8 (August 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-8 (August 2020) . - p.899-913 Titre : A randomised controlled trial of a relationship-focussed mobile phone application for improving adolescents' mental health Type de document : texte imprimé Auteurs : Bridianne O'DEA, Auteur ; Jin HAN, Auteur ; Philip J.

CALEAR, Auteur ; Aliza WERNER-SEIDLER, Auteur ; Belinda PARKER, Auteur ; Fiona SHAND, Auteur ; Helen CHRISTENSEN, Auteur Article en page(s) : p.899-913 Langues : Anglais (eng) Mots-clés : Adolescence  depression  e-health  mental health  relationships Index. décimale : PER Périodiques Résumé : 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.

The effects of a sleep-focused smartphone application on insomnia and depressive symptoms: a randomised controlled trial and mediation analysis / Aliza WERNER-SEIDLER in Journal of Child Psychology and Psychiatry, 64-9 (September 2023)

A novel way to reduce depression is by improving sleep. We evaluated whether an app-based intervention for insomnia improved sleep and depression, and whether changes in insomnia mediated changes in depression. Methods We conducted a 2-arm single-blind randomised controlled trial at the Black Dog Institute in Australia. Adolescents 12-16 years experiencing insomnia symptoms were randomly allocated to receive Sleep Ninja, an app-delivered cognitive behavioural therapy program for insomnia, or to an active control group involving weekly text message sleep tips. Assessments took place at baseline, 6 weeks (post-intervention) and 14 weeks (post-baseline). Co-primary outcomes were symptoms of insomnia and depression at post-intervention (primary endpoint). Intent-to-treat analyses were conducted. The trial is registered with the Australian and New Zealand Clinical Trials Registry, number ACTRN12619001462178. Results Between October 25, 2019, and September 6, 2020, 264 participants were randomised to receive Sleep Ninja (n=131) or to the control group (n=133). Relative to the control group, those allocated to the intervention reported a greater reduction in insomnia symptoms at 6 weeks (95% CI: 2.96 to 0.41, d=.41) and 14 weeks (95% CI: 3.34 to 0.19, d=.39), and a greater reduction in depression symptoms at 6 weeks (95% CI: 3.46 to 0.56, d=.28) but not 14 weeks (p<1). Change in insomnia mediated change in depression. No adverse events were reported. Conclusions An app-delivered program for insomnia could be a practical, non-stigmatising and scalable way to reduce symptoms of insomnia and depression among adolescents experiencing difficulties getting enough good quality sleep.
