The SAAF prevention program consisted of seven consecutive meetings held at community facilities, with separate parent and youth skill-building curricula and a family curriculum. Each meeting included separate, concurrent training sessions for parents and youth followed by a joint parent-youth session during which the families practiced the skills they learned in the separate sessions. Concurrent and family sessions each lasted 1 hour; thus, parents and youth received 14 hours of prevention training. During the weeks when the intervention families participated in the prevention sessions, the control families received three leaflets via post mail; one described various aspects of early adolescent development, another dealt with stress management, and the other provided suggestions for encouraging youth to exercise.
