Substituting SMSs for Provider-delivered Care to Improve Alcohol Use Outcomes

The goal of this clinical trial is to test whether a technology-substituted intervention (mhGAP-Remote) derived from the World Health Organization's (WHO) Mental Health Gap Action Programme-Intervention Guide (mhGAP-IG) is effective to reduce alcohol use among adults with and without HIV in Lesotho. Participants who receive the mhGAP-Remote intervention will complete one in-person intervention session pertaining to the mhGAP-IG module for alcohol use, followed by short message services (SMSs) related to the intervention material covered during the in person session. This will be compared to mhGAP-Standard, which involves 4 in-person sessions based on mhGAP-IG for alcohol use plus the option of 2 additional booster sessions. Participants in both treatment groups will complete assessments at baseline, 8-weeks follow-up, 20-weeks follow-up, and 32-weeks follow-up, consisting of self-reported questionnaires and laboratory tests.
