Project Summary/Abstract New approaches are needed to meet Los Angeles County EHE goals: uptake of PrEP, and knowledge of HIV status, is lagging particularly among young Black and Latinx Angelenos. Conditional cash transfers (CCTs)— which encourage behavior change through financial incentives—show promise for HIV prevention behaviors, but are under-investigated. CCTs should be responsive to local circumstances, and should use behavioral economic principles to leverage underlying preferences of the target population in order to maximize impact. This project aims to collect pre-implementation data in order to design an HIV prevention CCT intervention and implementation strategy for young Black and Latino cisgender men who have sex with men in Los Angeles County. This includes (A) collecting qualitative data about acceptability, appropriateness, and feasibility of this proposed CCT from consumers and key stakeholders (policymakers, service providers, community members, etc.); and (B) conducting a discrete choice experiment to identify the most-preferred attributes of such a CCT. Discrete choice experiments ask respondents to choose between hypothetical interventions that differ on key attributes: for example, the amount and frequency of financial incentive payment. Through a partnership between UCLA, APLA Health & Wellness, and DHSP—and with active engagement of community members throughout all phases of the research—this study would generate important insights essential for the design of a successful CCT program. Situated in the “Exploration” stage of the EPIS implementation framework, it will gather data to inform the subsequent design of a pilot CCT program which can be implemented and evaluated in follow-on research.
