Autism is a neurodevelopmental condition, characterized by altered social communication and repetitive behavior. Typically diagnosed in early childhood, screening and diagnosis at a later age can be challenging, particularly in girls who exhibit a wider range of behaviors and characteristics. This study aimed to examine the Childhood Autism…

The objective of this study was to determine the clinical features that moderate a later age at ASD diagnosis in females in a large sample of females with ASD. Within two large and independent ASD datasets (>20,000 females), females were first diagnosed with ASD 14-months later relative to males. This later age at diagnosis was moderated by a…

Males are more likely to be diagnosed with autism than females, and at earlier ages, yet few studies examine sex differences in screening. This study explored sex differences in psychometric properties, recommended cutoff scores, and overall scores of the Modified Checklist for Autism in Toddlers, Revised, with Follow-Up. Participants were 28,088…

Developmental language disorder (DLD) is a language deficit affecting approximately 7% of the general population and does not associate with any hearing impairment, neurological damage, or mental disorder. In DLD, the complications arise over time due to the learning difficulties experienced, which causes eventual cognitive delay compared to…

This study investigated the psychometric properties of the Early Numeracy Screener. The Early Numeracy Screener is a teacher-administered, paper-and-pencil test measuring counting skills, numerical relational skills, and basic arithmetic skills. Three hundred and sixty-six first graders took the Early Numeracy Screener at the beginning of the…

Recent efforts have focused on screening methods to identify children at risk for dyslexia as early as preschool/kindergarten. Unfortunately, while low sensitivity leads to under-identification of at-risk children, low "specificity" can lead to over-identification, resulting in inaccurate allocation of limited educational resources. The…

The Hong Kong Chinese version of the Autism-Spectrum Quotient-Child and Autism-Spectrum Quotient-Adolescent were examined for their psychometric properties and specificity on screening autism spectrum disorder against attention-deficit/hyperactivity disorder. This study recruited three groups of participants: typically developing children;…

All but seven U.S. states have laws that govern some aspects of dyslexia screening, intervention, or teacher training in public schools. However, in the three states that mandate child-level reporting, data indicate lower than expected rates of dyslexia identification when compared with commonly accepted dyslexia prevalence rates. To better…

In schools, screening is an effective method to identify students at-risk for emotional and behavioural disorders. Several intervention programmes such as Positive Behaviour Interventions and Supports, Response to Intervention, and Multi-tiered Systems of Supports call for the use of psychometrically sound screening instruments. This study…

Each year, the Interagency Autism Coordinating Committee (IACC) releases a list of scientific advances that represent significant progress in the field of autism research. The "2021 Summary of Advances" provides short, plain language summaries of the top research breakthroughs selected by the IACC from a pool of research articles…

This report documents the challenge of achieving inclusive education in Africa. Primary school completion rates are 10 percentage points lower for girls with disabilities than for girls without disabilities. For boys, the disability gap in primary completion rates is 13 points. Gaps are also large for secondary education completion and children…

Each year, the Interagency Autism Coordinating Committee (IACC) releases a list of scientific advances that represent significant progress in the field of autism research. The "Summary of Advances" provides short, plain language summaries of the top research breakthroughs selected by the IACC from a pool of research articles nominated by…

Purpose: Our objective was to replicate previous cross­linguistic findings by comparing Portuguese and U.S. children with respect to (a) effects of language, gender, and age on vocabulary size; (b) lexical composition; and (c) late talking. Method: We used the Language Development Survey (LDS; Rescorla, 1989) with children (18-35 months) learning…

The purpose of this study was to look at teachers' perceptions of challenging behaviors in the classroom, including students who had emotional or behavioral disorders and students who were at-risk for developing these problems. In the format of the survey, teachers were asked to consider the behaviors of their students in respect to gender. For…

The Autism Spectrum Quotient (AQ) has been widely used for measuring autistic characteristics in parents of children with autism spectrum disorders (ASD). Nonetheless, its psychometric validity is yet to be justified. This study tested the factor structure of the AQ by means of principal component analysis and confirmatory factor analysis using,…
