IN RESPONSE to the human immunodeficiency virus (HIV) epidemic among adolescents, there is an overriding urgency to develop and implement prevention interventions designed to motivate adolescents' adoption and maintenance of HIV-preventive practices. In the past decade, numerous HIV prevention programs have been designed, implemented, and evaluated. Modifying adolescents' HIV risk behavior has been a formidable challenge, but accumulating empirical evidence suggests that in general these programs are effective.1 However, estimating the magnitude of intervention efficacy across these studies has been difficult given the diversity of research designs and the heterogeneity of adolescent populations.
