Suicidal Behaviour

Stressful life events did not remain independently significant for suicidal behaviour after adjustment. Risk stratification protocols for suicidal behaviour often perform no better than chance. Depression was the strongest independent predictor of suicidal behaviour in the study. A prior suicide attempt is presented as one of the strongest predictors of future suicidal behaviour. Moderate insomnia was associated with roughly triple the risk of suicidal behaviour. Recent substance use increased suicidal behaviour risk by impairing decision-making and increasing impulsivity. About 20% of people who attempt suicide make another attempt.
