Prevention science sheds light on complex social policy problems, yet its social impact cannot reach full potential without the uptake of research evidence by policymakers. This mixed-methods study examined the US federal legislation pertaining to justice-involved youth to reveal opportunities for strengthening the use of prevention science in legislation. The results indicated that research language, particularly references to the type of study (e.g., longitudinal) or methodology (e.g., data mining), within bills predicted bill progression out of committee and enactment. Rigorous scientific methods may either lend credence to a bill during its progression in the legislative process or may be infused in language during mark-up and negotiation of bills that successfully progress in Congress. In-depth bill coding illustrated the ways that research has been used in legislation to define problems, reinforce effective practice, generate knowledge through research and evaluation, and disseminate findings. A prominent implication of these findings is that policies could be used to improve data monitoring and evaluation capacity in ways that enhance the implementation of evidence-based interventions. The comprehensive use of research in legislation increases the likelihood that policies reach their intended outcomes and benefit those they are designed to serve.

Recent evidence suggests parent-adolescent discrepancies regarding adolescent disclosure can provide insight into parent-child relations and adolescent adjustment. However, pathways linking discrepancies to adjustment are not well known. We tested a model linking parent-adolescent discrepancies in disclosure to adolescent substance use through affiliation with deviant peers. Using three annual waves of data from a community-based study (N = 357; 91% African American; 53% female; M(age) = 13.13 years, SD = 1.62 years at baseline), findings revealed that adolescent-reported secrecy and deviant peer affiliation were positively associated with substance use one and two years later, respectively, but there was no evidence of mediation. The results highlight associations of adolescent secrecy and adjustment, and the role peers play in adolescent substance use behaviors.

This study evaluated sibling effects of a family-based intervention aimed at preventing conduct problems in preschool-age siblings of adjudicated youths. Ninety-two families of preschoolers who had older siblings adjudicated for delinquent acts were randomly assigned to intervention and control conditions. Of these, 47 families had nontargeted school-age (5-11 years) or adolescent siblings (12-17 years) living at home. These families were considered in this report. The authors hypothesized group differences on antisocial behavior and positive peer relations for older siblings of targeted preschoolers. The authors examined outcomes of parent- and teacher-reported behavior immediately postintervention and 8 months postintervention. Findings revealed significant intervention effects 8 months following intervention for adolescent siblings on parent-reported antisocial behavior and positive peer relations. Teacher reports confirmed group differences for antisocial behavior immediately postintervention. Findings document benefits for adolescent siblings.
