The Child Focused Injury Risk Screening Tool (ChildFIRST) aims to measure movement competence and lower-limb-injury risk in 8-12-year-old children. Although the ChildFIRST has face and content validity evidence, stronger validity evidence is warranted. We tested the concurrent validity of the ChildFIRST using motion analysis, and the convergent…

Although motor problems are highly prevalent in children with autism spectrum disorder (ASD), they remain underdiagnosed. Questionnaire-based screening for motor problems could optimize current clinical practice. This study aimed to examine the psychometric properties of the developmental coordination disorder questionnaire (DCDQ) to screen for…

Autistic individuals often exhibit motor atypicalities, which may relate to difficulties in social communication. This study utilized a smart tablet activity to computationally characterize motor control by testing adherence to the two-thirds power law (2/3 PL), which captures a systematic covariation between velocity and curvature in motor…

Early childhood is a critical period characterized by rapid development of motor and language skills. Reliably assessing motor and language development in early childhood is difficult, and there is a lack of agreement on measurement tool use. This scoping review aims to identify measurement tools used to examine motor and language skills in…

Purpose: To evaluate the validity, reliability, and sensitivity of the novel Means-End Problem-Solving Assessment Tool (MEPSAT). Methods: Children with typical development and those with motor delay were assessed throughout the first 2 years of life using the MEPSAT. MEPSAT scores were validated against the cognitive and motor subscales of the…

A double-blind randomized controlled trial of n-3 long-chain polyunsaturated fatty acid (n-3 LCPUFA) supplementation or matching placebo during third trimester of pregnancy was conducted within the COPSAC[subscript 2010] mother-child cohort consisting of 736 women and their children. The objective was to determine if maternal n-3 LCPUFA pregnancy…

Without proper motor assessment, children with autism spectrum disorder may be placed in educational settings that are inappropriate for their motor abilities. However, many practitioners find it challenging to choose which assessment to use to assess these children, especially with the number of instruments available. The purpose of this study…

This study aimed to better understand predictors of evidence-based assessment practices for autism spectrum disorder (ASD). Nationwide, 402 school psychologists were surveyed for their knowledge of and training and experience with ASD on assessment practices, including reported areas of training needs. The majority of school psychologists reported…

Toddlers with autism spectrum disorder (ASD) were assessed on the Repetitive Behavior Scale-Revised (RBS-R), which we found to have acceptable internal consistency. Stereotypical subscale scores showed a negligible association with cognitive level, but correlated more strongly with adaptive and social indicators. Relative to earlier reported RBS-R…

The field of early autism research is in dire need of outcome measures that adequately reflect subtle changes in core autistic behaviors. This article compares the ability of a newly developed measure, the Brief Observation of Social Communication Change (BOSCC), and the Autism Diagnostic Observation Schedule (ADOS) to detect changes in core…

This study examines the criterion-related validity and clinimetric properties of the Assessment of Preschool Children's Participation (APCP) for children with cerebral palsy (CP). Eighty-two children with CP (age range, two to five years and 11 months) and their caregivers participated in this study. The APCP consists of diversity and intensity…

We report new clinical features of delayed motor development, hypotonia, and ataxia in two young children with mutations (R756H and D923N) in the "ATP1A3" gene. In adults, mutations in "ATP1A3" cause rapid-onset dystonia-Parkinsonism (RDP, DYT12) with abrupt onset of fixed dystonia. The parents and children were examined and videotaped, and…

Literature reveals that there are very few validated motor proficiency tests for young children. According to Gallahue and Ozmun, the Bruininks-Oseretsky Test of Motor Proficiency is a valid test. However, manipulative skills, which are classified as gross motor skills by most motor development specialists, are only tested in the Upper Limb…

Preliminary evidence suggests that children with Attention Deficit Hyperactivity Disorder (ADHD) may exhibit handwriting difficulties. However, the exact nature of these difficulties and the extent to which they may relate to motor or behavioural difficulties remains unclear. The aim of this study was to describe handwriting capacity in children…

The health benefits of physical activity are well documented, and the important role that schools and physical education (PE) can play in reducing sedentary behavior and contributing to population health has been identified. Although effective teaching is ultimately judged by student achievement, a major component of teacher and school…
