| This study involved secondary analyses of data from Positive Choices, a randomized clinical trial of a combined Motivational Interviewing and stage-based peer group intervention designed to reduce alcohol use and unprotected sexual behavior in a sample of 253 HIV+ men who have sex with men (MSM). The primary aims sought to examine factors influencing the occurrence of heavy alcohol use and unprotected anal sex factors across the study, focusing on sexual-event level (i.e., each sexual event day) and participant-level (i.e., participant characteristics) as well as the effects of the intervention and processes of change based on the Transtheoretical Model of Intentional Behavior Change. Major findings included an effect of main partner-type and an interaction between casual partner-type and depressive symptoms on unprotected anal sex at baseline, as well as evidence of complex relations between baseline behavior, younger age, and processes of change for safe sex and alcohol use in predicting same-day heavy alcohol use and unprotected anal sex across the 12-month study follow-up. Implications of these findings for future research and interventions targeting HIV+ MSM are discussed. |
