Recruiting a scientifically sound cohort of young men who have sex with men (YMSM) remains a challenge for researchers. The few cohort studies that have been conducted have relied on nonprobability sampling methods to construct their cohorts. While these studies have provided valuable information about HIV risk behaviors among YMSM, their findings have limited generalizability to broader YMSM populations. In this article, the authors describe a venue-based sampling methodology used to recruit a large and diverse cohort of YMSM from public venues in Los Angeles County, California. Venue-based sampling is a probability-based sampling design that combines outreach techniques with standard survey methods to enumerate, sample, and survey hard-to-reach populations in public venues where they are known to congregate and socialize. The study design allowed the authors to estimate individual, familial, and interpersonal psychosocial factors associated with HIV risk and health-seeking behaviors for a cohort of YMSM with known properties.
