• Conditions: HIV Infections
• Interventions: Behavioral: HIV Testing and Counseling; Behavioral: Contingency Management; Behavioral: Strengths-based case management

• Registration Number: NCT01161485
• Lead Sponsor: University of Colorado, Denver

Brief Summary

There is a need to identify and test effective strategies to reduce meth use and human immunodeficiency virus (HIV) risk behaviors in heterosexuals. This project will compare the efficacy of a manually-driven HIV testing and counseling (HIV T/C) intervention, with HIV T/C plus a manualized Contingency Management (CM), with HIV T/C plus CM plus a manualized Strengths-Based Case Management (CM/SBCM) model. As HIV T/C is the standard of care, the investigators are testing to determine if the investigators can enhance this standard. The specific aims and hypotheses of this protocol are:

1. To compare the relative efficacy of HIV T/C vs. CM vs. CM/SBCM on reducing drug use, specifically meth use. Hypothesis 1: CM/SBCM will reduce drug use more than those in CM (which will have more reduction than HIV T/C), potentially mediated through increased service utilization.

2. To compare the relative efficacy of HIV T/C vs. CM vs. CM/SBCM on reducing HIV and STI risk behaviors, specifically sex risk behaviors but also needle risk for injection drug users (IDUs). Hypothesis 2: CM/SBCM will have greater decreases in HIV risk behaviors than those in CM (which will have greater decreases than HIV T/C), potentially mediated through reduced drug use.

3. To compare the relative efficacy of HIV T/C vs. CM vs. CM/SBCM on improving mental health status. Hypothesis 3: CM/SBCM will have greater improvements in mental health status than those in CM (which will have greater improvements than HIV T/C), potentially mediated through increased service utilization and reduction of drug use, and potentially moderated by baseline meth use.

Arm && Interventions

Group	Intervention	Description
CM with Strengths-based case management	HIV Testing and Counseling	Strengths-based case management (SBCM) is a specific type of case management that is based on the following principles: 1) clients are most successful when they identify and use their strengths, abilities, and assets; 2) goal-setting is guided by the clients' perceptions of their own needs; 3) the client-case manager relationship is promoted as essential; 4) a creative approach to the use of the community will lead to the discovery of needed resources; and 5) case management is conducted in the community.
Contingency Management (CM)	HIV Testing and Counseling	Contingency management is based on Skinner's principles of operant conditioning in behavioral psychology, dating back to the 1930s (Skinner 1938). The basis of this model is that behavior is learned and reinforced by environmental contingencies that reward or punish.
