The goal of this prospective longitudinal study was to explore whether co-occurrent internalizing difficulties and aggression in early childhood convey increased risk for later mental health problems in middle childhood. Participants were mothers from the "Norwegian Mother, Father and Child Cohort Study" (MoBa), who provided assessments…

Adolescent marijuana use has become increasingly more problematic compared with the past; thus, understanding developmental processes that increase the liability of marijuana use is essential. Two developmental pathways to adolescent substance use have been proposed: an externalizing pathway that emphasizes the expression of aggressive and…

This study investigated the effect of a mindfulness-based intervention on pathological symptoms in boys with externalised disorders. A total of 24 elementary school students with externalising disorders, diagnosed by completing the Child Behavior Checklist (CBCL), were randomly assigned to a mindfulness-based intervention for two months. One…

The current study explored early adolescent child-level predictors (physical aggression, impulsivity, empathy) and contextual-level predictors (peer deviance, neighborhood dangerousness) of violent and nonviolent antisocial behavior (AB) in late adolescence. Additionally, we tested the moderating role of rejecting parenting on these associations…

This correlational study investigates the relationship between mobile phone use among elementary school students in Iran during the COVID-19 epidemic, and its effect on emotional-behavioural functioning and academic and social competencies. A researcher-devised questionnaire, and the Achenbach Child Behaviour Checklist (CBCL)-parental version, was…

The purpose of the present study was to examine the effects of teaching self-determination skills on the externalizing behaviors of students with emotional and behavioral disorders. The Research method was quasi experimental with pre and post-test and control group. To achieve our goals, thirty students who received high scores in the Child…

Background: Evocative gene-environment correlation (rGE) describes a process through which children's heritable characteristics influence their rearing environments. The current study examined if heritable influences on parenting and children's behavioral outcomes operate through child negative emotionality. Method: Using data from the Early…

Challenging behavior in preschool can lead to harmful outcomes for some children. While interventions have been shown to be effective in reducing or eliminating challenging behavior, evidence suggests that young children with challenging behavior are under-identified for services, increasing their risk for expulsion from early childhood programs.…

The Dual Failure Model suggests that peer victimization (social failure) and academic difficulties (academic failure) mediate the association between externalizing and later internalizing problems. The present study sought to better understand why children with externalizing problems develop later internalizing problems by testing the Dual Failure…

The current study explored the role of teacher-child relationship plays on the relationship between preschooler's shyness level and externalizing problem. The sample consisted of 463 children from 6 preschools of Shandong province in northern China. Mothers reported the shyness level, aggressive behavior, and attention problem of their children,…

Problem behavior of 52 children with Williams syndrome ages 6 to 17 years old was examined based on both parent and teacher report. Generally good inter-rater agreement was found. Common areas of problem behavior based both on parent and teacher report included attention problems, anxiety difficulties, repetitive behaviors (e.g., obsessions,…

Callous-unemotional (CU) behavior has been linked to behavior problems in children and adolescents. However, few studies have examined whether CU behavior in "early childhood" predicts behavior problems or CU behavior in "late childhood". This study examined whether indicators of CU behavior at ages 2-4 predicted aggression,…

Poverty is a well-established risk factor for behavior problems, yet our understanding of putative family mediators during early childhood (i.e., before age 5 years) is limited. The present study investigated whether the association between poverty and behavior problems during early childhood is mediated simultaneously by perceived parenting,…

A gap exists in the literature regarding aggression in autism spectrum disorders and how this behavior compares to other groups. In this multisite study, the "Children's Scale for Hostility and Aggression: Reactive/Proactive" and the Aggression subscale of the "Child Behavior Checklist" were rated for 414 children with autism…

This research examined whether following social and physical aggression trajectories across Grades 3-12 predicted psychological maladjustment. Teachers rated participants' (n = 287, 138 boys) aggressive behavior at the end of each school year. Following the 12th grade, psychosocial outcomes were measured: rule-breaking behaviors, internalizing…
