Community-Friendly Health Recovery Program (CHRP)

Principal Investigator: Michael Copenhaver, Ph.D.

Brief Overview

The Community-Friendly Health Recovery Program (CHRP) is designed to reduce sex- and drug-related HIV risk behavior among drug users in treatment. This program has been designed for implementation within drug treatment community based organizations, such as methadone maintenance programs, where large numbers of high risk drug users routinely participate in treatment.

Core Components of Intervention

  • Mode of Delivery and Duration:  Four 50-minute group sessions with two bachelor’s level trained facilitators using multi-modal delivery strategies to accommodate neurocognitive impairment common among this risk population.
  • Setting:  Methadone maintenance program (New Haven, CT, US)
  • Theoretical Basis:  CHRP is an abbreviated, adapted version of the Holistic Health Recovery Program and is based on the Information-Motivation-Behavioral Skills (IMB) model of behavior change (Fisher & Fisher, 1992).
  • Materials Available:  Intervention manual

The CHRP intervention was tested in a randomized controlled trial among 304 drug users in treatment who reported sex-related or drug-related HIV risk behavior. Compared to those in the active control group, participants in the CHRP intervention group demonstrated significantly greater improvement in drug risk-reduction skills (properly cleaning a syringe). In addition, those in the CHRP intervention group showed significantly greater improvement in sex risk-reduction skills (applying a female condom and applying a male condom) compared to the active control group. This intervention program was rated by the Substance Abuse and Mental Health Association (SAMHSA) as effective for improving behaviors known to decrease HIV risk.

Implementation History

CHRP was tested in a NIDA-funded randomized controlled trial at an inner city drug treatment program in New Haven, CT.
