The purpose of this study is to evaluate the Young Adult Centered HealthForce Training (YACHT) package in 41 Florida Department of Health (FDOH) contracted Counseling, Testing, and Referral (CTR) agencies across six Florida End the Epidemic (EHE) counties. Agencies will be cluster-stratified and randomized to either the YACHT intervention (20 agencies) or a comparison group (21 agencies). The primary effectiveness outcome is the number of HIV tests administered to young men who have sex with men (YMSM), and the primary implementation outcome is providers' fidelity to evidence-based practices (EBPs), including risk reduction counseling and PrEP referrals, as measured through mystery shopper assessments and agency-level data obtained from the Florida Department of Health. The study also includes qualitative interviews with agency representatives to identify barriers and facilitators to successful implementation of youth-specific EBPs within HIV CTR settings.

Young men who have sex with men (YMSM) continue to experience a disproportionate burden of HIV infection and remain less likely than other populations to engage in HIV testing, prevention services, and pre-exposure prophylaxis (PrEP). Counseling, Testing, and Referral (CTR) agencies play a critical role in improving the DIAGNOSE and PREVENT pillars of the Ending the HIV Epidemic initiative by providing culturally and developmentally responsive HIV prevention services. Previous mystery shopper evaluations of CTR agencies identified important gaps in provider delivery of evidence-based practices (EBPs), including risk reduction counseling, PrEP referrals, and culturally responsive care.

The purpose of this study is to evaluate the effectiveness of the Young Adult Centered HealthForce Training (YACHT) package for improving providers' fidelity to youth-focused EBPs and increasing HIV testing among YMSM in Florida CTR agencies. The study will be conducted in 41 Florida Department of Health contracted or direct-service CTR agencies located across six Florida End the Epidemic (EHE) counties.

This is a Type 2 hybrid implementation-effectiveness, cluster stratified randomized trial involving 41 agencies distributed across three blocks. Agencies will be randomized within blocks, with 20 assigned to receive the YACHT intervention and 21 serving as the comparison group.

The YACHT package consists of two complementary implementation strategies:

Workforce Development (WD), which provides agency-tailored guided problem solving and development of quality improvement strategies based on mystery shopper feedback reports; and Quality Management (QM) using standardized mystery shopper assessments that evaluate clinic environment, provider delivery of evidence-based practices, and culturally responsive care. Mystery shoppers will visit each participating agency twice per quarter, and aggregate agency-level feedback will be used to support quality improvement.

The primary effectiveness outcome is the number of HIV tests administered to YMSM using agency-level aggregate data obtained from the Florida Department of Health. The primary implementation outcome is providers' fidelity to evidence-based practices, including risk reduction counseling and PrEP referrals, as assessed through standardized mystery shopper evaluations across multiple domains. Secondary objectives include identifying barriers and facilitators to successful implementation of youth-specific EBPs through qualitative interviews with agency representatives using a mixed-methods approach.

Both intervention and comparison agencies will receive a final mystery shopper feedback report at the conclusion of the study and will have access to ongoing voluntary virtual Tailored Motivational Interviewing (TMI) workshops. Qualitative interviews will be conducted with representatives from both intervention and comparison agencies following completion of study activities.
