This study examined impulsivity as a moderator of the relationship between meth use and sexual risk behavior in a sample of HIV-positive meth-using Men who have Sex with Men (MSM). Higher impulsivity was associated with less education, lower income, being unemployed, psychiatric diagnosis, and higher Beck depression scores. Intensity of meth use and sexual risk behavior were significantly correlated. In a multiple regression analysis, more education, greater intensity of meth use and higher levels of impulsivity predicted more unprotected sex. To test for moderating effects of impulsivity, an interaction term was added to the regression. The interactive effects model was statistically significant. A plot of the interaction revealed that the relationship between intensity of meth use and total unprotected sex was strongest among participants who had higher levels of impulsivity. This suggests that targeting impulsivity in interventions may help reduce sexual risk behaviors in high intensity meth-using HIV-positive MSM.
