Suicide completers are more likely to be male and suffer from alcohol abuse, health problems (e.g. somatic illness), and narcissistic personality disorder. The findings emphasize the importance of implementing suicide prevention programs tailored to suicide attempters and completers.

Alcohol abusers seem to be prone to both suicide attempts and completions. The relationship between alcohol abuse and suicide in adolescence is complex. Objectives: To examine the role of alcohol abuse and dependence in adolescent suicide in psychological autopsy studies. Method: A search in the National Library of Medicine (NLM) PubMed database using "adolescents" and "all child: 0-18 years" as the search terms for age and "psychological autopsy" as the search term for title or abstract. Results: Forty articles met the selection criteria and each one is described. There was a high prevalence of alcohol abuse detected in the studies (range 21.42% to 43.47% in samples aged under 20 years). Alcohol misuse was present in suicides in the form of chronic abuse, acute abuse and dependence. Conclusions: Alcohol abuse and dependence is highly prevalent among adolescent suicides. In many studies, alcohol consumption is analyzed in combination with drug abuse. Further studies are necessary to clarify the prevalence of chronic and acute alcohol abuse in order to identify specific high-risk population groups and design antisuicidal interventions for them. Both acute and chronic alcohol use should be evaluated when assessing suicide risk in adolescents.
