PURPOSE We evaluate the efficacy of a short family intervention in reducing sexual risk behavior, drug use, and delinquent behaviors among homeless youth. METHODS A randomized controlled trial of 151 families with a homeless adolescent aged 12 to 17 years. Between March 2006 and June 2009, adolescents were recruited from diverse sites in Southern California and were assessed at recruitment (b...

Background: Impaired verbal abilities are one of the most consistent risk factors for serious antisocial and delinquent behavior. However, individuals with psychopathic traits often show serious antisocial behavior, despite showing no impairment in their verbal abilities. Thus, the aim of the current study was to examine whether psychopathy moderates the relationship between verbal abilities an...

This article reports a comparison on outcomes of 26-year-old males who were defined several years ago in the Dunedin longitudinal study as exhibiting childhood-onset versus adolescent-onset antisocial behavior and who were indistinguishable on delinquent offending in adolescence. Previous studies of these groups in childhood and adolescence showed that childhood-onset delinquents had inadequate...

Drawing on the self-system model, this study conceptualized school engagement as a multidimensional construct, including behavioral, emotional, and cognitive engagement, and examined whether changes in the three types of school engagement related to changes in problem behaviors from 7th through 11th grades (approximately ages 12-17). In addition, a transactional model of reciprocal relations be...

Risk and promotive effects were investigated as predictors of persistent serious delinquency in male participants of the Pittsburgh Youth Study (R. Loeber, D. P. Farrington, M. Stouthamer-Loeber, & W. B. van Kammen, 1998), living in different neighborhoods. Participants were studied over ages 13-19 years for the oldest sample and 7-13 years for the youngest sample. Risk and promotive effects we...

This study used a sample of 551 children surveyed yearly from ages 6 to 13 to examine the longitudinal associations among early behavior, middle-childhood peer rejection and friendedness, and early-adolescent depressive symptoms, loneliness, and delinquency. The study tested a sequential mediation hypothesis in which (a) behavior problems in the early school years are associated with middle-chi...

The aim of investigation was to assess the impact of subjective stress exposure on delinquent behaviour in children and adolescents. The study included 174 young male delinquents, selected by the method of stratified systematic (random) sample and divided into three age groups of <14, 14-17, and 18-21 years. General data, data on the type of criminal offence, and data on the type of deviant beh...

PURPOSE Communities That Care (CTC) is a prevention system designed to reduce levels of adolescent delinquency and substance use through the selection and use of effective preventive interventions tailored to a community's specific profile of risk and protection. This article describes early findings from the first group-randomized trial of CTC. METHODS A panel of 4407 fifth-grade students wa...

A growing body of research has documented associations between discrimination, anger and delinquency, but the exact nature of these associations remains unclear. Specifically, do aggressive behaviors emerge over time as a consequence of perceived discrimination and anger? Or do adolescents who engage in aggressive behavior perceive that they are being discriminated against and become angry? We ...

This paper describes the extent to which communities implementing the Communities That Care (CTC) prevention system adopt, replicate with fidelity, and sustain programs shown to be effective in reducing adolescent drug use, delinquency, and other problem behaviors. Data were collected from directors of community-based agencies and coalitions, school principals, service providers, and teachers, ...
