The present study examined how maltreatment experience was associated with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) symptoms in children under institutional care. The key caregivers of children and adolescents aged 6 to 18 years who were under institutional care in Nagano prefecture, Japan were asked to…

The present study investigated prenatal and early postnatal risk factors associated with developmental patterns of disruptive behaviors (DBs; e.g., hyperactivity-impulsivity, noncompliance, physical aggression) from ages 1.5 to 5 years in a population birth cohort (N = 2,057; 50.7% boys). Six high-trajectory classes obtained by latent growth…

This study aimed to investigate the predictive effect of problematic behaviours on cognitive tempo and attention level of 60-66 months old children attending preschool education institutions. The research data were obtained from 155 children between 60 and 66 months old attending independent kindergartens affiliated to the Ministry of National…

Objective: In this review, we examined if there is a deficit in facial recognition of emotion (FER) in children, adolescents, and adults with attention deficit hyperactivity disorder (ADHD). Background: Emotional regulation is impaired in ADHD. Although a facial emotion recognition deficit has been described in this condition, the underlying…

This pilot study sought to identify potential markers of improvement from pre-post treatment in response to computerized working memory (WM) training for youth (ages 8-18) with autism spectrum disorder (ASD) and comorbid intellectual disability (ID) in a single arm, pre-post design. Participants included 26 children with ASD and 18 with comorbid…

This systematic review was conducted to identify the literature examining the prevalence of problematic internet use (PIU) in individuals with autism spectrum disorder (ASD), the difference in prevalence of PIU between those with and without ASD, and the correlates of PIU in ASD. Ten studies were identified. The eight studies with comparison…

Objective: To examine the manifestation of cognitive control deficit of children with different levels of hyperactivity, an "at risk" dimension for ADHD. Method: A group of children with high hyperactivity (N = 40) and another group of children with low levels of hyperactivity (N = 38) performed a modified stop-signal anticipation task,…

Self-harm is purportedly common in autistic individuals, but under-researched, particularly in younger samples and those "without" intellectual disability. This study aimed to describe prevalence, profile and correlates of self-harm in autistic individuals without impairments in adaptive functioning. Parents of autistic participants (n =…

Introduction: This study seeks to psychometrically evaluate the inattention and hyperactivity/impulsivity subscales of the Vanderbilt ADHD Teacher Rating Scale (VADTRS) for the diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) in children and adolescents in Chile. Method: The sample included 353 students from the 2nd grade of primary…

Both maternal and paternal supportive parenting (i.e., sensitivity, warmth, stimulation, and engagement) across early childhood have been found to be associated with multiple domains of children's positive socioemotional functioning. However, few studies have considered how maternal and paternal supportive parenting may interact to impact child…

Teachers frequently rate boys as more hyperactive/impulsive than girls and Black children more than White children (DuPaul et al., 2016; Miller et al., 2009). Do these ratings reflect true differences in their behavior? Researchers have compared parent and teacher reports (Miller et al., 2009), but is hard to draw conclusions from such comparisons…

Background: Attention-deficit hyperactivity disorder (ADHD) is a risk for learning. Because ADHD commonly includes behaviours of inattention and behaviours of hyperactivity/impulsivity, how the two types of behaviours independently affect children's academic competence remains poorly understood. Aims: To investigate the impact of behaviours of…

The goal of the current study was to investigate the role of academic enablers on the association between symptoms of inattention and hyperactivity/impulsivity and academic achievement. There were 395 3rd through 5th grade students (48% boys). Students self-rated behavioral symptoms and classroom teachers completed ratings of academic enablers.…

The current research aims at finding the relationship between hyperactivity and math learning among a child with deep deafness. The research sample was 40 children from four levels of primary education, ranging in age from (10) to (17) years, the research tools was two tests: a test was used for the evaluation of mathematics, and Teacher's test of…

Previous studies have hinted at sex differences in developmental trajectories in ADHD symptoms; however, little is known about the nature or cause of these differences and their implications for clinical practice. We used growth mixture modelling in a community-ascertained cohort of n = 1,571 participants to study sex differences in ADHD symptom…
