The primary objective of this study was to test whether motivational interviewing (MI) provided over the mobile phone would reduce alcohol use among adults, including people living with HIV/AIDS, visiting primary care in Kenya. Heavy alcohol users voluntarily consented to being randomized to one of three study arms: standard in-person MI, mobile MI, or waitlist control receiving no intervention for 1 month followed by mobile MI. Alcohol use problems were assessed using validated screeners and changes in alcohol use were assessed at 1 month and 6 months after receiving the intervention. The investigators hypothesized that alcohol use would reduce after MI treatment compared to waitlist control, there would be no difference between standard in-person MI and mobile MI, and these reductions would be sustained out to six months following the intervention.
