The purpose of this study is to pilot test an innovative program development project in an open trial format an 8-session, individual, cognitive-behavioral therapy based, intervention on ten (10) HIV-infected men who have sex with men who report very high levels (>10 episodes) of sexual transmission risk behavior (unprotected anal intercourse with serodiscordant partners).

This is an innovative program development project that will, over the next year, pilot test, in an open trial format an 8-session, individual, cognitive-behavioral therapy based, intervention on ten (10) HIV-infected men who have sex with men who report very high levels (>10 episodes) of sexual transmission risk behavior (unprotected anal intercourse with serodiscordant partners). That is, to pilot test a novel prevention intervention designed to effect reductions in sexual transmission risk behavior among the riskiest men in the largest HIV risk group in the US. Effecting even modest reductions in the mean number of risk acts in this group will likely have substantial public health significance through the number of averted new HIV infections. Traditional secondary HIV intervention strategies (e.g., Information, Motivation, Behavior change (IMB)) models only have modest effects for HIV-positive MSM and there is evidence to suggest that these effects tend to diminish over time.

Inclusion Criteria:

• Age 18 years old or older

• Self-reports being HIV-infected
• Reports engaging in 10 episodes or more of unprotected anal intercourse (receptive or insertive) in the past three months with male partners who are not HIV-infected or whose serostatus is unknown.
• Is capable of completing and fully understanding the informed consent process and the study procedures and assessments in English

Exclusion Criteria:
