The mediators of real-world executive functions in autism during the transition into adulthood are mainly unknown. This study aimed to identify the mediators for the behavioral and cognitive domains of real-world executive functions in late adolescent and young adult autistic populations. We followed up 289 autistic children (aged 11.6 ± 3.8, male…

Longitudinal data from a large sample of twins participating in the Netherlands Twin Register (n = 42,827, age range 3-16) were analyzed to investigate the genetic and environmental contributions to childhood aggression. Genetic auto-regressive (simplex) models were used to assess whether the same genes are involved or whether new genes come into…

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…

Although many studies have investigated links between maternal employment and children's wellbeing, less research has considered whether the stability of maternal employment is linked with child outcomes. Using unique employment calendar data from the Fragile Families and Child Wellbeing Study (N = 2,011), an urban birth cohort study of largely…

Background: Previous studies suggest that children with Down's syndrome (DS), a genetically based neurodevelopmental disorder, demonstrate motor problems and cognitive deficits. The first aim of this study was to examine motor skills and executive functions (EFs) in school-age children with DS. The second aim was to investigate the relationship…

Aim of this study was to compare children diagnosed with Pervasive Developmental Disorder (PDD) according to DSM-IV-TR and DSM-5 diagnostic systems. One hundred fifty children aged between 3 and 15 years diagnosed with PDD by DSM-IV-TR were included. PDD symptoms were reviewed through psychiatric assessment based on DSM-IV-TR and DSM-5 criteria.…

Parent-child interaction plays a crucial role in early language acquisition. In young typically developing children, direct and indirect relationships between parent gesture, child gesture and child language have been observed. Far less is known about these relationships in atypical language development. The present study investigated parent…

The purpose of this study was to investigate sex differences in behavioral and emotional problems in high-functioning girls and boys with autism spectrum disorder. The results obtained by adolescents with autism spectrum disorder were compared with those of typically developing girls and boys. Correlations between parents' and adolescents' ratings…

Purpose of this quasi-experimental trial was to investigate the effect of Pivotal response treatment (PRT) versus treatment as usual (TAU) on autism symptoms. Children with autism spectrum disorder (ASD), aged 3-8 years, received either PRT (n = 11) or TAU (n = 13). Primary outcome measure was the total score on the Autism Diagnostic Observation…

Agreement between the DSM-5, DSM-IV, and Checklist for Autism Spectrum Disorder was assessed in 125 children with autism spectrum disorder (ASD), which included high and low functioning autism (HFA and LFA) and pervasive developmental disorder not otherwise specified (PDDNOS), and children with other clinical disorders (e.g., ADHD, mental…

The aim was to evaluate conceptual scoring of lexical organization in bilingual children with language impairment (BLI) and to compare BLI performance with monolingual children with language impairment (MLI). Word associations were assessed in 15 BLI and 9 MLI children. BLI were assessed in Arabic and Swedish, MLI in Swedish only. A number of…

Objective: Little empirical attention has been paid to the validity scales of the Trauma Symptom Checklist for Children (TSCC). The purpose of this study is to examine the prevalence of cases identified by the validity scales and its analytical impact. Methods: The current study compares regression models using data from two community samples (n =…

Purpose: This article provides benchmark data on within-group effect sizes from published randomized clinical trials (RCTs) supporting the efficacy of trauma-focused cognitive behavioral therapy (TF-CBT) for traumatized children. Methods: Within-group effect-size benchmarks for symptoms of trauma, anxiety, and depression were calculated via the…

The years from 3 to 6 are a time when children develop fundamental movement skills that are the building blocks for the functional movements they use throughout their lives. By 6 years of age, a typically developing child will have in place a full range of movement skills, including, running, jumping, hopping, skipping, climbing, throwing,…

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…
