Who could benefit from this research
✓Could help
Ideal participants are Black and Latino bisexual men aged 21 and older who live in or regularly spend time in the study area and are willing to carry a smartphone for brief location-based surveys.
✕Less likely to help
People who are not Black or Latino bisexual men, are under 21, or are unwilling to carry a phone or share location data are unlikely to benefit directly from participating.
What this research studies
Researchers will first gather short survey responses from a general adult sample to create neighborhood-level maps of different kinds of stigma and affirmation. Then they will recruit Black and Latino bisexual men to carry a smartphone that records location and prompts brief momentary surveys many times per day (ecological momentary assessment, EMA). Those momentary reports will capture substance use, sexual risk moments, and experiences of stigma or affirmation, which will be linked back to the neighborhood stigma maps. Combined analyses will show whether being in stigmatizing or affirming places corresponds with increased or decreased substance use and HIV risk behaviors.
Why it matters
Potential benefit: If successful, this work could point to specific places and moments where tailored outreach, support, or prevention could reduce substance use and HIV risk for Black and Latino bisexual men.
How similar studies have gone: Prior studies using EMA and geolocation have linked momentary experiences to substance use and sexual risk, but combining intersectional geospatial stigma mapping with EMA focused on bisexual Black and Latino men is relatively new.
