Interventions to reduce sexual risk for the human immunodeficiency virus in adolescents, 1985-2000: a research synthesis.

Objective: To summarize studies that have tested the efficacy of human immunodeficiency virus (HIV) sexual risk-reduction interventions in adolescents.

Data Sources: Reports were gathered from computerized databases, by contacting individual researchers, by searching conference proceedings and relevant journals, and by reviewing reference sections of obtained articles.

Study Selection: Studies were included if they investigated any educational, psychosocial, or behavioral intervention advocating sexual risk reduction for HIV prevention; used experimental designs (or other designs with adequate comparison groups); had behavioral-dependent measures relevant to sexual risk; sampled adolescents (age range, 11-18 years); and had sufficient information to calculate effect size (ES) estimates.
