Parent Intervention. The primary feature of the parent component is a written manual distributed in modules to mothers that teaches them how to communicate effectively with their children about sex or tobacco risk behaviors and how to improve their relationships with their children. This is accompanied by two face-to-face intervention sessions for mothers, during which they are given the intervention materials and an opportunity to participate in role playing activities with other parents, and by regular contact by trained parent volunteers to determine if the parent has implemented the manual contents. Mothers and their adolescents attend Linking Lives events together at the school in the evenings and on weekends during which time adolescents attend their own intervention sessions at the same time mothers are attending theirs (mothers in the control condition participate in sessions on helping their children choose a high school).
