This longitudinal study examined the joint role of pubertal timing and temperament variables (emotional reactivity and self-regulation) in predicting adolescents' internalizing symptoms. The multiethnic sample included 1,025 adolescent girls and boys followed from age 11 to age 15 (M age = 11.03 years at Time 1). In structural equation models, age 11 measures of pubertal timing, emotional react...

BACKGROUND On March 11, 2011, a massive undersea earthquake and tsunami struck East Japan. Few studies have investigated the impact of exposure to a natural disaster on preschool children. We investigated the association of trauma experiences during the Great East Japan Earthquake on clinically significant behavior problems among preschool children 2 years after the earthquake. METHOD Partici...

The investigation was performed on 113 adolescents in the age between 15 and 18 years (63 boys, 50 girls). Corah Dental Anxiety Scale (CDAS) and Children's Fear Survey Schedule - Dental Subscale (CFSS-DS) were used for evaluation of dental fear and Child Medical Fear Questionnaire (CMFQ) for evaluation of the fear of medical treatment. Achenbach Youth Self Report questionnaire (YSR) was used fo...

The authors compared behavior problems and social competence in 126 boys and girls (age 6-11) from violent and nonviolent families, on the basis of maternal ratings on the Achenbach Child Behavior Checklist. Girls from violent families were reported as showing more internalizing behavior problems and a lower level of social competence than their nonviolent comparison group. Boys from violent fa...

BACKGROUND Violence exposure within each setting of community, school, or home has been linked with internalizing and externalizing problems. Although many children experience violence in multiple contexts, the effects of such cross-contextual exposure have not been studied. This study addresses this gap by examining independent and interactive effects of witnessing violence and victimization i...

This study assessed prospective, bidirectional associations between maternal endorsement of spanking and children's internalizing and externalizing behavior problems in low-income urban African American and Hispanic (N = 592) families drawn from the Three City Study. Children in sample families were followed from early childhood through middle childhood with 3 sets of interviews and assessments...

The current study examined relational aggression as a potential mechanism that explains the association between off-time pubertal development and internalizing problems in youth. Youth gender was also examined as a moderator for the association between these variables. It was hypothesized that early pubertal maturation would be associated with higher levels of relationally aggressive behavior w...

OBJECTIVE To estimate genetic, shared environmental, and nonshared environmental contributions to stability and change in internalizing and externalizing problems. METHOD Maternal Child Behavior Checklist ratings were obtained for 3,873 twin pairs at age 3 and 1,924 twin pairs at age 7. For 1,575 twin pairs, ratings were available at both ages. RESULTS For Internalizing/Externalizing rating...
