Addressing comorbidities by integrating substance use counseling into HIV testing for YMSM and transgendered people.

SWERVE is a randomized control trial testing the efficacy of a substance use brief intervention (SUBI) as part of standard HIV prevention and care services in Southeast Michigan for young gay, bisexual, and other men who have sex with men and transgender people. The SWERVE intervention is being compared to standard of care HIV counseling, testing, and referral to services (CTR) in a four-arm trial. Participants receive two test counseling visits (either SUBI and SUBI, SUBI and CTR, CTR and SUBI, or CTR and CTR) followed by 5 follow-up visits. 


This academic-community partnership includes colleagues at the University of Michigan Center for Sexuality & Health Disparities as well as two AIDS Service Organizations: UNIFIED: HIV Health and Beyond, and Wellness AIDS Services.

The SWERVE substance use brief intervention incorporates motivational interviewing techniques to assess participants willingness to change their behavior and encourage them to adopt the strategies necessary to reduce their substance use.

  1. Determine the efficacy of the SWERVE intervention in promoting and sustaining repeat HIV-testing behaviors among HIV-negative participants and linkage and retention in care among newly diagnosed HIV+ participants.

  2. Test the comparative efficacy of the four study arms in reducing sexual risk and drug use mediators associated with our outcomes.

  3. Compare intervention effectiveness on risk reduction outcomes based on the moderation of agency-level factors (test counselor characteristics, fidelity, acceptability, and satisfaction) and area indicators (socioeconomic disadvantage, HIV prevalence).

  4. Assess AIDS service organizations’ acceptability of and satisfaction with SUBI and its potential for sustainability as measured by a cost-effectiveness analysis.
