Youth with autism spectrum conditions have been shown to be at an increased risk for bullying victimization. The overall aim of this study was to identify factors associated with increased risk for bullying victimization in youth with autism during middle childhood to early adolescence (aged 5-12 years) and to explore the potential time-ordered…

Emerging research suggests that adolescents at high-achieving schools (HAS) in Western societies are at elevated risk for problem behaviours. This cross-sectional study explored whether adolescents attending HAS in a non-Western setting show similar risk patterns and if contextual (school-, family-, and peer-based) factors typically associated…

Background: Limited data exist on problematic sexual behaviour (PSB) in youth with developmental disabilities in South Korea. Method: Sixty-one parents of children with intellectual disabilities or autism spectrum disorder (aged 13-30) reported children's PSB and emotional, behavioural, cognitive, and interpersonal factors. The frequency of PSB in…

Understanding executive functions (EFs) development is of high value to global developmental science. Recent calls for a more inclusive and equitable developmental science argue that tasks and questionnaires that are developed using only a subset of the population are not likely to be appropriate for EFs measurement in global contexts unless…

This study examines the reliability of parental concern (PC) as an indicator for mental disorders in preschool-aged children in a clinical setting, aiming to establish sensitivity and specificity, evaluate PC's predictive value for specific diagnoses, and explore the influence of child age on predictions. The sample comprises 574 children referred…

Employing a multi-method approach, we investigated observed and parent-rated child behavioral inhibition (BI) and maternal reports of their own negative affectivity (NA) as predictors of young children's internalizing problems. Participants were 201 children who were siblings between 2.5 and 5.5 years of age (mean = 3.86, standard deviation =…

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,…

This prospective study examined the effects of early childhood physical aggression and violence exposure on bullying victimization/perpetration and attitudes toward guns and violence in early adolescence (EA) in a high-risk sample. Participants included 216 mother-child dyads from an ongoing longitudinal study using multi-method assessments (e.g.,…

The study examined teasing experiences among 74 individuals with autism spectrum disorder (ASD; M age = 115.7 months [9.6 years]; 83.8% male). Experiences were examined from parent, teacher, and child's own perspectives. Factors potentially associated with being teased were investigated. Comparison data were ascertained on typically developing…

An extensive literature links language problems with behavioral difficulties and academic underachievement. Although less extensive, emerging literature suggests that temperament, Positive Affectivity (PA) in particular, contributes to language development. Thus, the present study was focused on PA related temperament dimensions in infancy as…

Background: Prediction of antisocial behavior is important, given its adverse impact on both the individuals engaging in antisocial behavior and society. Additional research identifying early predictors of future antisocial behavior, or antisocial propensity, is needed. The present study tested the hypothesis that both concern for others and…

High and stable levels of aggression and the presence of aggressive behaviour in multiple settings according to different informants are risk factors for later problems. However, these two factors have not been investigated in early childhood. The present study investigates trajectories of parent-reported child aggression from 1.5 up to 6 years of…

The purpose of this study was to investigate agreement and theoretically relevant moderators of agreement between non-parent caregivers and teachers in a sample of traumatized youth. Two hundred eleven children (ages 5-16 years) who had experienced abuse and/or neglect were administered the Trauma Symptom Checklist for Children (TSCC) shortly…

The present study examined agreement between scores obtained from self-reports of behavioral and emotional problems obtained from 513 Algerian adolescents on the Youth Self-Report (YSR) with scores obtained from reports provided by their parents on the Child Behavior Checklist (CBCL). The correlations between self- and parent-report were larger…

This exploratory longitudinal study examined behavioral outcomes and parenting stress among families with children adopted from foster care, taking into account environmental and biological risk factors. Child internalizing and externalizing problems and parenting stress were assessed in 82 adopted children and their families at 2 months…
