The diagnostic utility of the Woodcock-Johnson III Tests of Cognitive Abilities and Clinical Clusters was assessed in a sample of 52 children (26 Attention Deficit/Hyperactivity Disordered (ADHD) and 26 matched controls). Multivariate analysis of variance followed by post-hoc testing and d-ratios yielded some statistically significant and…

The objective of our study was to evaluate the frequency of treatable inborn errors of metabolism (IEM) in a clinical sample of Mexican children and adolescents with neurodevelopmental disorders (NDD). Amino acids and acylcarnitines in blood samples of 51 unrelated children and adolescents were analyzed by tandem mass spectrometry to detect…

School disruption (SD) places students at risk of early school departure and other negative psychological outcomes. Based on the data derived from a sample of Ontario children and youth, this study aims to identify risk factors associated with SD among 1,241 school-aged students. A logistic regression model revealed that substance use, family…

The inclusion of children with special educational needs into mainstream schools needs effort and cooperation by all those involved. Both educators and medical professions need to be skilled in identifying and supporting neurodiversity. This study explores the cross-professional understanding and support of four of the most prevalent…

This study reports findings from a large, multisite randomized controlled trial examining the efficacy of a treatment for this population, known as ACCESS -- Accessing Campus Connections and…

The Canadian Little Developmental Coordination Disorder Questionnaire (Little DCDQ-CA) is a parent-report screening instrument that identifies 3- to 4-year-old children who may be at risk for Developmental Coordination Disorder (DCD). We tested the criterion validity of the Little DCDQ-CA in a sample of preschool-aged children in the United States…

The aim of the study is to examine the predictive effect of self-regulation on peer relations. Data were collected from 3486 children. Of the study sample, 1736 were girls (49.9%) and 1747 were boys (50.1%). All the children were from high SES families and attending private preschools in 10 cities in Turkey.
