Young Men's Health Project Targeting HIV Risk Reduction and Substance Abuse

1. Adapt YMHP for clinic and phone delivery by existing HIV clinic staff community health workers (CHWs), who work with YMSM ages 15-24. Investigators will conduct focus groups with staff to obtain input on how best to implement YMHP to maximize feasibility, acceptability, and sustainability, as well as issues with adapting the YMHP for delivery to YMSM ages 15-18 and for phone delivery. 2. Compare the effectiveness of clinic-based versus phone-based delivery of YMHP in the context of health care access. In order to inform future implementation, investigators will test the effectiveness of YMHP delivered via these two modalities. 1. Assess the cost-effectiveness of both delivery formats of YMHP to enhance the likelihood of uptake of this best evidence intervention. The hypothesis is that phone-based will be more cost-effective than clinic-based 2. Assess the Five Components of the Self-Management Model and how these components vary over time, are directly improved by the interventions, and mediate intervention effects. 3. Test a sustainable model of YMHP implementation in real world adolescent clinics. Investigators will utilize local supervisors within the clinic setting to sustain the CHWs fidelity to delivering the motivational interviewing (MI)-based YMHP intervention. Fidelity will be monitored throughout the trial and assessments and qualitative interviews will be conducted with key stakeholders to determine the barriers and facilitators of YMHP implementation utilizing the Exploration, Preparation, Implementation, Sustainment model (EPIS). Aims will be achieved over two phases of the study. Phase I: Investigators will conduct research (Exploration and Preparation phases of EPIS model) to obtain implementation feedback to best adapt YMHP for clinic-based CHWs, further incorporate PrEP navigation services, and expand the YMHP protocol to be relevant for Telephone-based Motivational Interviewing (TBMI). We will train a minimum of 2 CHWs at each clinic drawing on the Implementation Science Core (ISC) to apply best-practices in training. Once CHWs demonstrate competence according to the Motivational Interviewing Treatment Integrity (MITI), Phase 2 will begin. Phase II: Personnel will recruit and enroll 180 YMSM, ages 15-24, 60 at each of the three sites. Sessions will be audio-recorded for MITI fidelity coding, and CHWs and supervisors will be given implementation support throughout. Prior to implementation, immediately at the conclusion of the intervention delivery phase, and one year after, the ISC will conduct interviews with CHWs, supervisors, and clinic leaders to obtain information about the barriers and facilitators of implementation and sustainment. Target n: 180 YMSM across three sites (60 per site).
