Brief Alcohol Intervention and mHealth Booster for Suicidal Adolescents

The primary goal of this study is to test the acceptability and feasibility of iASIST (integrated Alcohol and Suicide Intervention for Suicidal Teens), a novel adjunctive intervention for alcohol use and alcohol-related suicidal thoughts and behaviors for suicidal adolescent inpatients. The investigators will first conduct an open trial with 10 adolescents and their parents to test iASIST and make subsequent changes to the booster. Next, the investigators will conduct a randomized trial with 50 adolescents and their parents to test the feasibility and acceptability of iASIST as well as associations with alcohol- and suicide-related outcomes at 3 months post-discharge, relative to participants who receive an attention-matched comparison condition focused on the role of a healthy lifestyle in mental health that includes a post-discharge mHealth control targeting the maintenance of a healthy lifestyle.
