There are currently no published randomized controlled studies examining psychosocial interventions for college students with ADHD, and none specifically targeting AUDs in this population at any age, despite the clear indication from emerging research of the need for such interventions. In the current study, the investigators will develop BA-based treatment intended to increase involvement in healthy, goal-directed activities (e.g., academic, recreational or social activities) and to reduce problematic drinking behaviors and other risk behaviors (e.g., unsafe sex) among college students with ADHD (Behavioral Activation for Attention & Alcohol Disorders; BAAAD). Finalized treatment manuals, altered based on focus group feedback, will be tested in a stage I randomized controlled trial (RCT) among 80 college students randomized to BMI + BAAAD or BMI + supportive counseling (SC). The investigators expect that BMI + BAAAD will be successful with college students with ADHD, in terms of decreasing the escalation of problematic alcohol use behaviors, as compared to BMI + SC. This treatment development study will set the stage for larger-scale RCTs.
