Abstract
Alcohol misuse is a risk factor in suicide and parasuicide. To measure the prevalence of alcohol use disorders in a cohort of psychiatric admissions using the Alcohol Use Disorders Identification Test (AUDIT), and the relationship between the AUDIT score and suicidality. Consecutive psychiatric admissions were interviewed with a lifestyle survey that included the AUDIT, and admission case notes were reviewed. Out of 200 subjects, 48.5% scored 8 or more (indicating hazardous or harmful alcohol use) and 22.5% scored 16 or more (indicating significant alcohol dependence) on the AUDIT. There were no significant gender differences. Alcohol misuse was strongly associated with suicidality. The AUDIT questionnaire should be incorporated into psychiatric assessments when risk of self-harm is being evaluated. Further research is warranted to examine the impact of interventions for alcohol use disorders in psychiatric settings on self-harm and suicidal ideation.
