Over years, the terms used to identify intellectual disability, which was previously known as "mental retardation," have changed. This has been due to the heavy stigma associated with bearing its label (Tassé & Mehling, in press). This article examines defining and determining intellectual disability (intellectual developmental…

How prevalent is dyslexia? A definitive answer to this question has been elusive because of the continuous distribution of reading performance and predictors of dyslexia and because of the heterogeneous nature of samples of poor readers. Samples of poor readers are a mixture of individuals whose reading is consistent with or expected based on…

We investigated the clinical validity of the BADEC, an abbreviated, five-item version of the Autism Detection in Early Childhood, level-2 screening tool for autism. Initially developed by Nah et al. (2019) using a research sample, the present study replicated Nah et al. (2019) procedures in a clinical population. Using a cutoff score of five, five…

This study aimed to investigate factors associated with a delayed autism spectrum (ASD) diagnosis when compared to children with either no or early ASD diagnosis. Among 893 children assessed for ASD before age 8, 39% had no ASD at baseline, of which 21% received a later ASD diagnosis. Autism symptoms, diagnostic history of other developmental…

The assessment instruments for diagnosing children with autism spectrum disorder have been developed mostly in affluent, English-speaking countries. Among the most popular has been the Autism Diagnostic Interview--Revised. This article reports its use in Iran with the dual aims of confirming the factor structure of the revised Autism Diagnostic…

Early diagnosis of autism spectrum disorder (ASD) facilitates access to interventions that improve outcomes for children and families. Understanding developmental and behavioral manifestations of symptoms and competencies improves early diagnosis. The authors illustrate the benefits of using the ZERO TO THREE "DC:0-5™: Diagnostic…

Introduction: Individuals with Autism Spectrum Disorder display a pattern of social communication deficits and restricted and repetitive behaviors that leave them particularly vulnerable to developing anxiety. The presence of a co-occurring Intellectual Disability further complicates the situation, compromising traditional diagnostic techniques…

Many researchers report risk ratios of White students to Black students with disabilities to show disproportionality and draw the conclusion discrimination exists. Risk ratios, upon further inspection, have methodological and philosophical problems which challenge the usefulness. A qualitative literature review provides a framework for…

Accurate diagnosis of attention deficit/hyperactivity disorder (ADHD) in children is difficult because the major symptoms, inattentiveness and hyperactivity, can be exhibited by any child. This study finds evidence of systematic differences in diagnosis and treatment of ADHD due to third party financial incentives. In some states, due to the…

This study was designed to track the developmental trajectory, during the first 24 months of life, of 335 low-risk infants later diagnosed with Autism Spectrum Disorder and identify early deviations observed in routine Well Care checkups. We compared their achievements to typically developing children and to children later diagnosed with…

Recent studies of autism diagnosis in New Zealand have revealed inconsistent implementation of best practice standards in autism assessment and high rates of parental dissatisfaction with the diagnostic process. These findings have arisen despite the development and dissemination of the New Zealand Autism Spectrum Disorder Guideline (the…

Although it affects as many as one in five individuals in the United States and 80 percent of all children labeled as learning disabled, dyslexia remains poorly understood in educational circles. It was the science supporting the clinical diagnosis of dyslexia that led Laura, a physician, and others to start a public charter school in Baton Rouge…

Providing both a theoretical framework and practical strategies, this resource will help teachers, counselors, and related service providers develop understanding and empathy to improve outcomes for culturally and linguistically diverse (CLD) students with disabilities.
