Background: Methamphetamine-dependent gay and bisexual men (GBM) are at high risk for HIV transmission, largely due to drug-associated sexual risk behaviors. This project evaluated the efficacy of four behavioral drug abuse treatments for reducing methamphetamine use and sexual risk behaviors among this population. Methods: In this randomized controlled trial, 162 methamphetamine-dependent (SCID-verified) GBM in Los Angeles County were randomly assigned to one of four treatment conditions for 16 weeks: standard cognitive behavioral therapy (CBT, n = 40), contingency management (CM, n = 42), combined cognitive behavioral therapy and contingency management (CBT + CM, n = 40), and a culturally tailored cognitive behavioral therapy (GCBT, n = 40). Stimulant use was assessed thrice-weekly during treatment using urine drug screens (48 measures). Sexual risk behaviors were monitored monthly (four measures). Follow-up assessments were conducted at 6 (80.0%) and 12 months (79.9%).
