The purpose of this study is to compare the effects of interventions for drinking-reduction and antiretroviral therapy (ART) adherence among HIV-positive primary care patients. The interventions consist of brief meetings to discuss drinking and ART adherence enhanced with daily self-monitoring through the use of a smart phone application that tracks drinking and other aspects of health. These meetings will either be based on the Clinician's Guide, a brief intervention for heavy drinking in primary care settings advocated by the National Institute on Alcohol Abuse and Alcoholism, or Motivational Interviewing. Participants will be assessed at baseline, 30, 60, 90 days, 6 and 12 months after baseline. By the end of treatment (60 days) and throughout the follow-up period, alcohol use is expected to highest among participants who receive the Clinician's Guide alone, intermediate among participants who receive the enhanced Clinician's Guide, and lowest among participants who receive enhanced Motivational Interviewing.
