Abstract
OBJECTIVE Depression is one of the most prevalent and disabling mental health conditions among young people worldwide. The health and economic burdens associated with depressive illness are substantial. Suicide and depression are closely intertwined, yet a diagnosis of depression itself lacks predictive specificity for suicidal behaviour. To better inform suicide prevention and early intervention strategies for young people, improved identification of modifiable intervention targets is needed. The objective of this review was to identify clinical, psychosocial and biological correlates of suicidality in young people diagnosed with a broad range of unipolar and bipolar depressive disorders. METHOD Systematic searches were conducted across MEDLINE, Embase and PsycINFO to identify studies of young people aged 15-25 years diagnosed with unipolar or bipolar depressive disorders. An assessment of suicidality was required for inclusion. Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 and Synthesis Without Meta-analysis guidelines. RESULTS We integrated findings from 71 studies including approximately 24,670 young people with clinically diagnosed depression. We identified 26 clinical, psychosocial and biological correlates of suicidality. Depression characteristics (type and severity), psychiatric comorbidity (particularly anxiety and substance use disorders) and neurological characteristics emerged as having the most evidence for being associated with suicidal outcomes. Our ability to pool data and conduct meaningful quantitative synthesis was hampered by substantial heterogeneity across studies and incomplete reporting; thus, meta-analysis was not possible. CONCLUSION Findings of this review reinforce the notion that suicidality is a complex phenomenon arising from the interplay of multiple contributing factors. Our findings question the utility of considering a diagnosis of depression as a specific risk factor for suicidality in young people. Suicidality itself is transdiagnostic; adoption of a transdiagnostic approach to investigating its aetiology and treatment is perhaps warranted. Future research investigating specific symptoms, or symptom networks, might help to further our understanding of suicidality among young people experiencing mental illness.

Schizophr Res 2021; 235:80-90. [PMID: 34332428 DOI: 10.1016/j.schres.2021.07.029] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Revised: 07/15/2021] [Accepted: 07/19/2021] [Indexed: 12/14/2022]
Abstract
BACKGROUND Suicide is the main cause of premature death in patients with psychosis. Therefore, the goal of the present study was to review suicide in adolescents with psychotic disorders by evaluating factors associated with suicidal acts. Ours is the first systematic review of suicide in this population. METHOD We performed a systematic review of suicide in adolescents (10 to 19 years) with psychotic disorder. RESULTS We identified 10 studies, only 2 of which were randomized clinical trials. The results revealed high rates of suicidal behaviour in this population: the times of higher risk were the time before admission and the period immediately following discharge. The factors most associated with suicide attempts were depression, distress with psychotic symptoms, fewer negative symptoms at baseline, positive symptoms, and anxiety disorders. Associated factors included previous psychiatric history or psychiatric admissions, female sex, prior suicidal behaviour, family history of completed suicide, and nicotine dependence. LIMITATIONS Clinical and methodological diversity of the studies. CONCLUSIONS Adolescents with psychotic disorders had a major risk of suicidal behaviour, and specific factors were associated with the act. Early detection of adolescents with psychosis is vital, since it has been found that early intervention can prevent suicidal acts in young people. However, it is necessary to perform more studies, particularly randomized controlled trials, on suicide and suicide attempts, particularly in adolescents.
