Description of aim 3 implementation outcomes.

Evaluation parameter	Description	Methods	Frequency
Theoretical model	Evaluate changes in alcohol use and HIV prevention or treatment (eg, PrEPa and ARTb use) using the theory-of-change model measuring change and which sociodemographic and behavioral characteristics are associated with change in order to understand any subpopulations receptive toward the strategic priorities and pathways of change identified by our model.	Quantitative surveys at each visit and biomarker data	Baseline and 6-month follow-up
Participants’ self-reported fidelity	Evaluate completeness of the intervention through a checklist assessing whether specific topics were covered during intervention sessions, including an assessment of the quality of intervention interactions, where participants will rate implementer engagement during intervention sessions.	Quantitative surveys at each visit and biomarker data	Baseline and 6-month follow-up
Acceptability and uptake of and satisfaction with the intervention	Evaluate the organizational, provider, and PLWc acceptability of the intervention, including the number and percentage of sessions attended and IDId feedback following the sessions. Success would be >80% of sessions attended with very good/good feedback postsessions.	Mixed methods	Postimplementation mixed methods: 6-month survey (all participants), followed by IDIs with 20 providers and 20 participants
Fidelity to training assessment	Evaluate sessions (20% recorded and reviewed by the principal investigator) and fidelity to training using a checklist of key parameters. Success would be >80% of sessions supervised following training SOPse.	Monitoring forms: comparison of SOPs and audio-recorded MM+f sessions	Postimplementation mixed methods: 6-month survey (all participants), followed by IDIs in 20 providers and 20 participants
Feasibility of the intervention	Evaluate organizational, provider, and PLW views on the feasibility and scalability of the implementation of the intervention.	Mixed methods	Postimplementation mixed methods: 6-month survey (all participants), followed by IDIs in 20 providers and 20 participants
