About this trial
In this project, the investigators will implement innovations to extend use of Contingency Management (CM) to facilitate alcohol use reduction among people living with HIV (PLWH). The investigators' approach to extending CM will use mobile health (mHealth) tools including a smartphone breathalyzer device with accompanying app and a wrist worn alcohol biosensor. Participants will be engaged in mobile facilitated CM for 30-60 days with follow-up out to 6 months.
