Clinical characteristics and 6-month follow-up of adults with and without alcohol use disorder who self-harm

Abstract

Background: Alcohol use disorder (AUD) is associated with suicidal behavior, but prospective clinical studies are lacking. Aim: To compare clinical characteristics and 6-month outcomes in persons with and without AUD who self-harm. Methods: 804 adults (mean age 33, age range 18-95, 541 women and 263 men, 666 with suicide attempts and 138 with non-suicidal self-injuries at index) at three Swedish university hospitals took part in a research interview that included the Mini International Neuropsychiatric Interview (MINI). Subsequent non-fatal suicidal behavior within six months was identified by record review; suicides were identified by national register. Results: At index, 39% of the men and 29% of the women had AUD. Over two thirds of these cases (69%) were identified by the MINI, but not by clinical AUD diagnosis. While trait impulsivity was more common among persons with AUD than those without (56% vs 36%, P adj =
