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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Non-Contingent Condition | Experimental | Participants will wear a wrist biosensor with daily CM based on smartphone breathalyzer readings for 30 days; then for a second 30 days, encouragement to reduce drinking but payment not based on drinking. |
|
| mHealth and CM | Experimental | Participants will wear a wrist biosensor with daily CM based on smartphone breathalyzer readings for 30 days; then for a second 30 days, weekly CM based on wrist biosensor readings. Participants will also interact with a mobile health application to facilitate drinking reduction. |
|
| CM | Experimental | Participants will wear a wrist biosensor with daily CM based on smartphone breathalyzer readings for 30 days; then for a second 30 days, weekly CM based on wrist biosensor readings |

|---|---|---|---|---|
| Counseling | Behavioral | Brief counseling including personalized feedback on breath alcohol concentration, cognitive task performance and physical functioning |
|
| Measure | Description | Time Frame |
|---|---|---|
| Percent days abstinent via smartphone breathalyzer readings | Within-subject comparison between percent abstinent days based on smartphone breathalyzer readings during the 30-Day Phase 1 Contingency Management induction compared to the 30-day baseline period based on self-report on the timeline followback | Baseline to 30 Days |
| Predict percent days abstinent via smartphone breathalyzer readings based on risk factors. | All participants will attempt to reduce alcohol consumption. Only those who are able to will continue to the second phase of the intervention. We will seek to identify which factors are predictive of abstinence. | Baseline to 30 Days |
| Perceived value and ease of use of novel contingency management strategies to reduce alcohol consumption. | Participants will engage in a Contingency Management program aimed at reducing alcohol consumption. A novel CM delivery system will be used intended to gamify the process. | 30 Days to 60 Days |
| Drinking reduction through Contingency Management will predict non-drinking outcomes | Participants who are able to successfully reduce their alcohol consumption may see other health benefits including reduced HIV viral load. | Baseline to 90 days |
| Measure | Description | Time Frame |
|---|---|---|
| Percent days abstinent via wrist biosensor readings | Among responders during the Phase 1 Contingency Management induction period, comparison among Phase 2 study conditions regarding percent abstinent days based on wrist biosensor readings. Percent days abstinent at baseline based on self-report and based on smartphone breathalyzer readings during Phase 1 will be included in this model. | Baseline to 60 Days |
| Measure | Description | Time Frame |
|---|---|---|
| Percent days abstinent via self-report | Among responders during the Phase 1 Contingency Management induction period, comparison among Phase 2 study conditions regarding percent abstinent days during the post-intervention, follow-up period based on self-report assessed with the timeline followback from days 61-180. Percent days abstinent at baseline based on self-report and based on smartphone breathalyzer readings during Phase 1 and based on wrist biosensor readings during Phase 2 will be included in this model. |
