Purpose: This study tests the effectiveness of a behavioral intervention to reduce sexual risk behavior in HIV-positive, methamphetamine-using men who have sex with men (MSM). It builds on the findings of a previous study (R01 DA012116, "Promoting safer sex in HIV+ homosexual and bisexual men who use methamphetamine"). That study achieved significant short-term results that eroded over time. Accordingly, this study hypothesizes that the addition of a maintenance component to the already proven counseling and educational components of the treatment model will result in longer-lasting positive effects.
Study summary: Methamphetamine use by MSM has been consistently associated with increased HIV transmission. In the previous funding period we demonstrated reductions in transmission risk behavior associated with participation in our behavioral intervention; however, these improvements eroded over time, underscoring the need to develop and test interventions designed to enhance longer-term behavior change. The objective of this study is to evaluate the efficacy of an intervention designed to maintain reductions in high-risk sexual practices achieved by methamphetamine-using HIV+ MSM. Three major questions addressed are: 1) Can methamphetamine-using HIV+ MSM modify their high-risk sexual practices over an extended (16-month) period? 2) Do "group maintenance sessions" result in less erosion of behavioral improvements? 3) Are the underlying mechanisms the same for acquisition and maintenance of behavior change? We will assign 450 sexually active HIV+ MSM who regularly use methamphetamine and who have had unprotected sex with an HIV-negative or unknown-status partner to one of three conditions: 1) an eight-session intervention, combining client-centered motivational interviewing and structured behavioral counseling to address five intervention domains (context of unsafe sex/drug use; condom use; safer sex negotiation; disclosure; and enhancement of social supports); 2) the same eight counseling sessions (i.e., identical to condition 1 above), plus eight group-format safer sex maintenance sessions, which utilize clinical strategies from relapse prevention to identify high-risk situations and develop effective coping strategies; or 3) an attention-control condition that is time-equivalent to condition 2 above, and addresses diet, exercise, and HIV. Thus we will determine whether longer-term maintenance of safer sex behaviors is possible among HIV+ methamphetamine-using MSM, a population that remains at very high risk of HIV transmission, and for which substitution therapies to promote cessation and risk reduction are not yet available.
