Moon and Sun Brothers: A Community Prevention Intervention

This study, called "Moon and Sun Brothers: A Community Prevention Intervention," is testing a group program designed for Hispanic immigrant gay or bisexual men, or men who have sex with men (GBMSM). The goal is to help reduce the risk of getting HIV. The program is delivered in Spanish and involves group activities and counseling. Researchers want to see if this intervention improves sexual behaviors, increases self-esteem, and strengthens social support. They will compare participants who receive the intervention to those who don't. You may be able to join if you are a Latino/x/e male, 18 or older, speak Spanish, and have sex with men. The study is looking for 360 participants.
