The Peer-Driven Intervention (PDI) trains injection drug users (IDUs) to recruit and deliver HIV prevention interventions to their immediate peers in a drug use community through a modest incentives program.
Adult injection drug users
Core Components of Intervention
- Mode of Delivery and Duration: Three or more full-time Health Educators deliver prevention services to several active IDUs and train them to become peer-recruiters. IDUs are given a modest monetary incentive for IDU peers they recruit and an additional incentive for delivering HIV prevention education information to each peer. IDUs are also given HIV prevention services in the PDI Office.
- Setting: Peer networks and PDI offices operating out of community storefronts (Connecticut, US)
- Theoretical Basis: Group-Mediated Social Control (Heckathorn, 1990)
- Materials Available: PDI Intervention Summary
The PDI was effective in reducing HIV risk behaviors. Further, the PDI was able to recruit significantly more IDUs to receive HIV information and testing and cost significantly less than traditional outreach efforts (i.e., an outreach worker does recruiting) (Broadhead et al., 1998).
The PDI has also been used increase drug treatment in the U.S. (Broadhead et al., 2002) and is efficacious in other cultural contexts such as Russia (Broadhead et al., 2006), Vietnam, and China (Broadhead et al., 2009). The model has also been expanded and adapted for use in accessing other at-risk and network-based populations such as commercial sex workers, men-who-have-sex-with-men (MSM), high-risk heterosexuals (HRH), and homeless/runaway youth (e.g., Broadhead et al., 2006; Broadhead et al., 2009).
