OLVE (Socially Optimized Learning in Virtual Environments) is an HIV prevention interactive video (IAV) intervention that relies on a neuroscience based theory, stressing both cognitive and affective factors in decision-making. SOLVE (funded by an NIAID/NIH grant), involved a sex-positive game, where YMSM go on a virtual date in which men’s choices (e.g., about alcohol, drugs, type of sex, risky sex, etc.) affect how the scenario unfolds.
