A Triadic Intervention for Adolescent Sexual Health: A Randomized Clinical Trial.

Objectives: In this study, we evaluate the efficacy of Families Talking Together (FTT), a triadic intervention to reduce adolescent sexual risk behavior.

Methods: Adolescents aged 11 to 14 and their female caregivers were recruited from a pediatric clinic; 900 families were enrolled; 84 declined. Families were randomly assigned to FTT or 1 of 2 control conditions. The FTT triadic intervention consisted of a 45-minute face-to-face session for mothers, health care provider endorsement of intervention content, printed materials for families, and a booster call for mothers. The primary outcomes were ever having had vaginal intercourse, sexual debut within the past 12 months, and condom use at last sexual intercourse. Assessments occurred at baseline, 3 months post baseline, and 12 months post baseline.

Results: Of enrolled families, 73.4% identified as Hispanic, 20.4% as African American, and 6.2% as mixed race. Mean maternal age was 38.8 years, and mean adolescent grade was seventh grade. At the 12-month follow-up, 5.2% of adolescents in the experimental group reported having had sexual intercourse, compared with 18% of adolescents in the control groups ( < .05). In the experimental group, 4.7% of adolescents reported sexual debut within the past 12 months, compared with 14.7% of adolescents in the control group ( < .05). In the experimental group, 74.2% of sexually active adolescents indicated using a condom at last sexual intercourse, compared with 49.1% of adolescents in the control group ( < .05).

Conclusions: This research suggests that the FTT triadic intervention is efficacious in delaying sexual debut and reducing sexual risk behavior among adolescents.
