Effectiveness of an HIV prevention program for immigrant Latino men who have sex with men in Canada: Results of a pilot study

This study piloted the GPS (Gay-Positive Sex) Latino program for men who have sex with men (MSM) who immigrated to Canada. GPS Latino is an individual counseling intervention program that involves the provision of information, motivational interviewing, and behavioral skills building to reduce risk behaviors associated with HIV and STI transmission. We designed a pre-post study without control to assess the effects of GPS Latino on depression, loneliness, the self-efficacy of condom use negotiation, and condomless anal sex (CAS). During the study, one HIV-positive peer counselor administered six 2-hour counseling sessions to 11 participants living with HIV and 10 HIV-negative MSM Latinos living in Toronto, Canada. A paired t-test and a McNemar test were employed to assess the effects of GPS Latino twelve months after the start of the intervention. Our study shows a reduction in CAS (any partner) from 90% at the baseline to 62% at the 12-month follow-up (p = 0.06). The findings also indicate an increase from 19.2 to 21.5 (p = 0.01) in self-efficacy of negotiating condom use in HIV-negative participants. As a peer-led counseling intervention, GPS Latino may offer an efficient way of concurrently reducing CAS and increasing condom use negotiation in immigrant Latino men who have sex with men.
