Contingency Management for Methamphetamine Abstinence and HIV Post-Exposure Prophylaxis in Men Who Have Sex With Men
Summary
This study seeks to decrease methamphetamine use and concomitant high-risk sexual behaviors among methamphetamine-using men who have sex with men (MSM) by combining a biomedical intervention with a behavioral intervention. The behavioral intervention will consist of an 8-week course of contingency management (CM) through which participants will be reinforced for testing negative for methamphetamine metabolites during periodic urine analyses. The biomedical intervention involves a 28-day course of an antiretroviral drug (Truvada) to be administered after an unanticipated HIV risk exposure (i.e., engaging in either receptive or insertive anal sex without a condom with someone who is HIV-positive or of unknown status). In combining these two interventions, this study seeks to evaluate the combined intervention's effects on sexual risk behaviors and methamphetamine use.
