Risk as a Moderator of the Effects of Prevention Programs for Children from Divorced Families: A Six-Year Longitudinal Study

Program by risk interactions were assessed to evaluate whether the long-term effects of two preventive interventions for children from divorced families were moderated by baseline levels of risk. Six-year prospective relations between childhood (ages 9–12) and adolescence (ages 15–19) were examined in 68 children who comprised the control group of a randomized trial. Analyses indicated that two childhood variables predicted multiple adolescent outcomes: environmental stressors and externalizing problems. A risk index composed of these 2 variables was highly predictive of internalizing and externalizing problems, competence, substance use, and mental disorder 6 years later. Analyses of the full sample (N=218) indicated that program effects were greater for children with higher risk scores and that the programs attenuated the relation between risk and adolescent internalizing and externalizing problems, competence, and mental disorder.
