 A two group randomized controlled trial will be used to compare the brief MI intervention to TAU with 50 adolescents psychiatrically hospitalized for a suicide plan or attempt who have co-occurring alcohol use. Adolescents admitted to the unit for a suicide plan or attempt will be screened by PI OBrien or Co-I White within 24 hours of their admission to determine if they meet criteria for alcohol use in past month by selecting 1-6 on Question 1 of the Adolescent Drinking Questionnaire ADQ. Then Co-I White or PI OBrien in the event Co-I White is unavailable will administer the Drug Use Questionnaire DUQ, Timeline Follow-back Interview TLFB, Brief Situational Confidence Questionnaire BSCQ, Comprehensive Effects of Alcohol CEOA, Opinions About Alcohol Use OAAU, Suicide Ideation Questionnaire SIQ, Inventory of Motivations for Suicide Attempts IMSA, and a subset of questions from the Columbia-Suicide Severity Rating Scale C-SSRS. Once assessment measures are completed, participants will be randomized to either the experimental condition or TAU. Randomization will be accomplished by using an urn randomization procedure used to retain random allocation while balancing relative probabilities of assignment to treatment groups. Urn randomization in contrast to simple or block randomization is dynamic; the probability of treatment assignment changes dependent on the degree of treatment imbalance throughout the course of the trial. We will randomize by 1 ADQ score i.e., adolescents scoring 4 which indicates drinking at least 2-3 times per week and 2 gender. The adolescent will receive the individual MI intervention in a private room on the inpatient psychiatric unit; the family intervention will be delivered in a private room on the unit, ideally the next day. After the intervention the adolescent will complete the exit interview and Session Evaluation Form SEF to assess acceptability. Once a discharge date is made for the participant, PI OBrien or Co-I White will schedule a 3 month follow-up appointments with the adolescent and guardian; the ADQ, DUQ, TLFB, BSCQ, CEOA, SIQ, IMSA, and C-SSRS will be readministered at the follow-up assessment in a private room in the visitors area of the inpatient psychiatric unit by RA Wigglesworth, so that the clinician conducting the assessment is blind to condition.
