RESPECT is the first individual level intervention to be added to the Diffusion of Effective Behavioral Interventions (DEBI). The RESPECT intervention utilizes a client-focused, interactive HIV risk reduction counseling model based on Project RESPECT. This study was a randomized controlled trial, implemented in 5 cities, to assess the efficacy of HIV prevention counseling in reducing high risk sexual behaviors and preventing new STDs. The study evaluated a 2-session and 4-session counseling interventions utilizing the RESPECT protocol, and found that risk taking behaviors were reduced in both counseling models. Delivery of brief didactic prevention messages were also evaluated, but did not result in significant behavior changes.
