Multiple group analysis and general growth mixture modeling was used to determine whether aggressive-disruptive behavior trajectories during elementary school, and their association with young adulthood antisocial outcomes, vary by gender. Participants were assessed longitudinally beginning at age 6 as part of an evaluation of 2 school-based…

Background: Little is known about the factors affecting the risk of behavioural and emotional problems in young people with severe intellectual disability (ID), although such evidence as there is suggests that there may be differences between the pattern of risk factors in this group and those that operate in general population samples of the same…

This study was a randomized control trial (RCT) of Parent Management Training--The Oregon Model (PMTO) in Norway. A sample representing all health regions of Norway and consisting of 112 children with conduct problems and their families participated in the study. Families were randomly assigned to either PMTO or a regular services comparison…

This study examined parent and child gender effects on parents' attributions and beliefs in regards to child symptoms of attention-deficit/hyperactivity disorder (ADHD). Participants included mothers and fathers of 19 girls and 17 boys with ADHD. Groups of boys and girls, aged 5-13 years, were equated on age and medication status, as well as ADHD…

School suspensions are commonly used in schools to address challenging student behaviours, often on the understanding that suspensions send a clear message to the school community about what is acceptable behaviour. However, there is a growing body of evidence that school suspensions have a range of unintended negative consequences including…

It is commonly assumed that exposure to terrorism may lead to violent behavior, but there is little empirical research on the relationship between these two variables. In the present paper, we examined the extent to which exposure to terrorism contributes to violent behavior among adolescents. In addition, we considered the role of environmental…

The Regulatory Emotional Self-Efficacy (RESE) scale was developed to assess perceived self-efficacy in managing negative (NEG) and in expressing positive (POS) affect (G. V. Caprara & M. Gerbino, 2001). In this study of young adults, the factorial structure of the RESE scale was found to be similar in Italy, the United States, and Bolivia: In…

This study evaluated the Gentle Warrior Program, a traditional martial arts-based intervention to reduce aggression in children, as it was implemented in three elementary schools. The sample consisted of 254 children in grades 3, 4, and 5 who participated in the Gentle Warrior Program as part of a larger school violence intervention. Results…

Objective: To examine gender differences among children meeting symptom criteria for DSM-IV attention-deficit/hyperactivity disorder (ADHD) identified in a nationally representative sample of Australian children. Method: From 2,404 children aged 6 to 13 years, 225 boys and 99 girls with ADHD symptoms were identified using the parent version of the…

Cohort-sequential latent growth modeling was used to analyze longitudinal data for children's externalizing behavior from four overlapping age cohorts (4, 5, 6, and 7 years at first assessment) measured at three annual time points. The data included mother and father ratings on the Child Behavior Checklist and the Five-Factor Personality Inventory…

We studied the long-term cumulative effects of two common indices of childcare--the total number of hours of non-maternal care and the mean hour-weighted child-to-caregiver ratio per caregiving situation--on mental development and socioemotional adjustment from birth to 4.5 years old in a non-risk middle-class sample of girls and boys after taking…

Although many clinical studies document a relationship between gambling and suicidality, evidence of this association in general population surveys has been mixed. Probing this association in a nationally representative sample of young adults with data from the National Longitudinal Survey of Adolescent Health, we made same gender comparisons of…

We examined leisure behaviours and the relationships between leisure and a variety of problem behaviours in a sample of 1422 Hungarian adolescents (age range: 14-19). Findings from multivariate analyses suggest that some aspects of adolescent leisure, such as family or conventional activities, act as protective factors against problem behaviours,…

The goal of this multi-method study was to examine how child gender and coparenting processes influence associations between family stress and toddlers' social adjustment. The participants, 104 dual-earner couples and their 2-year-old children, were videotaped in their home during a freeplay activity. Mothers and fathers completed questionnaires…
