The University of California at Los Angeles convened the workshop at the request of the Contraceptive Evaluation Branch of the National Institutes of Child Health and Human Development to determine the feasibility of recruiting the population at risk and of designing interventions that promote the use of condoms and spermicides. Twenty-one representatives from health departments, drug abuse treatment centers, academic institutions, service organizations, and the community discussed issues relating to population characteristics, educational strategies, and recruitment techniques. Participants developed a consensus document that focused on the most effective recruitment and intervention strategies and that discussed the issues of locations, recruitment targets, anticipated difficulties, and ethical considerations. The majority of workshop participants agreed that an intervention should target the sexual couple. Intervention concerns include obtaining trust, maintaining participation, and identifying ways of having the maximum impact. List of participants and 26 references. (Author abstract modified)
