HC-HMP: Healthy Choices Implementation Trial (HC-HMP)

Participants receive HC-HMP without any of the three implementation strategies (Video Introduction, Tailored Digital Messaging, or Asynchronous Support).

Healthy Choices is an evidence-based behavioral intervention consisting of four individual counseling sessions grounded in Motivational Interviewing. Sessions are delivered remotely by trained interventionists using secure videoconferencing and address alcohol use, HIV prevention and treatment behaviors, stress management, and other HIV-related health behaviors.

HealthMpowerment is a mobile digital health platform providing digital health education and behavioral resources, peer and community features, self-monitoring tools, scheduling and reminders, and other intervention resources.

Participants receive HC-HMP with the Low-Touch implementation strategy (Video Introduction) and without the Medium-Touch or High-Touch implementation strategies.

Number of Healthy Choices counseling sessions completed by each participant during the 3-month intervention period. Participants may complete 0 to 4 sessions. A session is considered completed when the participant attends at least 15 minutes of the 30-minute virtual session.

Engagement with the HealthMpowerment platform assessed using platform-generated usage paradata, including frequency of logins, time spent on the platform, and use of individual HMP features.

Alcohol use assessed using the Timeline Followback (TLFB), which assesses daily alcohol consumption during the prior 14 days. The outcome is the maximum number of drinks consumed during a 3-day period.

Dichotomous status-neutral HIV transmission risk measure based on participant self-report. Participants reporting no condomless anal or vaginal intercourse, PrEP adherence of more than four doses per week, or self-reported viral suppression are classified as low risk (0); participants not meeting any of these criteria are classified as higher risk (1).
