What this trial studies
This project aims to implement innovative strategies to reduce alcohol consumption in individuals living with HIV through Contingency Management (CM) techniques. The approach incorporates mobile health (mHealth) tools, including a smartphone breathalyzer and a wrist-worn alcohol biosensor, to monitor and encourage reduced alcohol use. Participants will engage in mobile-facilitated CM for a duration of 30 to 60 days, with follow-up assessments extending up to six months to evaluate the effectiveness of the intervention.
Why it matters
Potential benefit: If successful, this study could significantly improve alcohol use outcomes for individuals living with HIV, enhancing their overall health and quality of life.
How similar studies have gone: Other studies utilizing mobile health interventions for alcohol use reduction have shown promise, suggesting that this approach may be effective.

Inclusion Criteria: * Frequent alcohol use in the past 30 days based on responses on the Timeline Followback (TLFB; Sobell and Sobell, 2003) * HIV positive * Fluency in English * Willingness to attempt alcohol abstinence for at least 30 days and then to attempt alcohol use on fewer days than at baseline after that * Willingness to use smartphone applications and biosensor devices (i.e., breathalyzer device and wrist sensor) for alcohol use reduction purposes in the study. If participants do not have a compatible smartphone to use, they will be loaned one by the study Exclusion Criteria: * Psychiatric conditions that would interfere with participation in the study * Current alcohol withdrawal as indicated by a score of 8 or higher on the Clinical Institute Withdrawal Scale (CIWA; Sullivan et al., 1989) or lifetime history of medically assisted detoxification * Two positive breath alcohol concentration (BrAC) readings (i.e., \> 0.00%) at an in-person screening appointment. After participants blow their first positive BrAC, they will be allowed to reschedule and participate at another time, however if they blow a second positive BrAC, they will be excluded from this study and offered referrals for alcohol treatment. * Currently seeking or past-12-month history of inpatient or intensive treatment for addictive behaviors * Psychosis or other severe psychiatric disability * Pregnancy, nursing or lack of reliable birth control use for women who have not yet reached menopause
