BACKGROUND: Informed by diathesis-stress models of suicide risk, this paper investigated the role of proximally-occurring stressful life events in the first transition from suicidal ideation to suicide attempt in adolescence. Interactions between stressful life events and psychiatric disorders in relation to this progression were also examined.
METHODS: Data are from a subsample (N = 928) of adolescents with lifetime suicidal ideation from the National Comorbidity Survey-Adolescent Supplement. Logistic regression analyses compared adolescents who had transitioned to a first suicide attempt (n = 81) in the year prior to the study to adolescents with suicidal ideation only (n = 847).
RESULTS: Multivariate logistic regressions implicated increased risk for progression from suicidal ideation to a first suicide attempt in the presence of a recent romantic break-up as well as more recent stressful life events. However, among adolescents with suicidal ideation and either a recent romantic break-up or above-average recent stressors, neither a disruptive behavior disorder, mood disorder, nor a substance use disorder intensified the risk for progressing to a first suicide attempt. LIMITATIONS: Analyses are cross-sectional and therefore limit causal inferences.
CONCLUSIONS: Findings underscore the importance of comprehensive suicide risk evaluations that consider proximally-occurring interpersonal stressors which may influence the first transition from thinking about suicide to acting in adolescence.
