Methods: A trained research assistant administered the Short-Grit and Center for Epidemiological Studies Depression (CES-D) scales and surveyed participants of a communitybased behavioral health intervention for demographic, health, and sexual behaviors. Results: Of 239 participants, two thirds scored in the high grit category. A greater proportion of men with high grit demonstrated higher educational attainment, were employed in the prior six months, reported very good/excellent health, were HIV positive, scored <16 on the CES-D, and had more friends who were gay. After controlling for other variables, high grit was associated with higher odds of having more friends who are gay and lower odds of alcohol use, unemployment, and a high CES-D score. Conclusions: These findings demonstrate that grit could be an important mechanism upon which to focus health and behavioral interventions for BMSM.
