This paper examines age of autism spectrum disorder (ASD) identification and related factors in a diverse urban sample, focusing on ASD identification in the East African Somali community. The overall average age of initial ASD identification was 4.8 years. Somali children received an initial clinical diagnosis of Autistic Disorder later than…

Low birth weight (LBW) and prematurity have been identified as health risks associated with adverse developmental and educational outcomes. This study examined whether such risks affected children's receiving special education services. Using a nationally representative sample from the Pre-Elementary Educational Longitudinal Study, we investigated…

There has been a marked increase in accommodation requests from students with disabilities at both the postsecondary education level and on high-stakes examinations. As such, accurate identification and quantification of normative impairment is essential for equitable provision of accommodations. Considerable diversity currently exists in methods…

Despite efforts to detect autism spectrum disorder during toddlerhood, many children with autism spectrum disorder remain undiagnosed until school age. To identify characteristics of children whose autism spectrum disorder might not be diagnosed during toddlerhood, this study used archived Autism Diagnostic Interview-Revised records to examine the…

This study explored factors associated with age of identification of autism spectrum disorder (ASD). Results of a one-way ANOVA indicated differences in age of diagnosis among the four regions in the United States, F(3, 650) = 7.618, p = 0.01. Tukey's post hoc comparisons of the groups indicated that the mean age of diagnosis in the Midwest (M =…

Each year, the Interagency Autism Coordinating Committee (IACC) releases a list of scientific advances that represent significant progress in the field. The "2017 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 the members.…

The "Woodcock-Johnson III" Tests of Achievement grade norms versus age norms were examined in the calculation of discrepancy scores in 202 college students. Difference scores were calculated between the "Wechsler Adult Intelligence Scale-3rd Edition" Full Scale IQ and the "Woodcock-Johnson III" Total Achievement,…

Each year, the Interagency Autism Coordinating Committee (IACC) releases its annual list of scientific advances that represent significant progress in the field. The 20 studies selected have given new insight into the underlying biology of autism spectrum disorder (ASD) and potential risk factors, examined the state of the science in early…

Each year, the Interagency Autism Coordinating Committee (IACC) releases its annual list of scientific advances that represent significant progress in the field. The 20 studies selected have given new insight into the underlying biology of autism spectrum disorder (ASD) and potential risk factors, tested approaches for improving early screening…

The identification of young children in need of special education and related services has been an issue with advocates, service providers, parents, researchers, and policy makers for years. The enactment in 1975 of the Education for All Handicapped Children Act (P. L. 94-142) required states and jurisdictions to provide special education and…

An area of research with autism spectrum disorders (ASD), which has received a considerable amount of attention recently is early diagnosis. This phenomenon is due largely to encouraging results from intensive intervention programs for children at very young ages. While five types of ASD exist, efforts in this area have focused almost exclusively…

Background: To test whether the retrospective reporting of the age of onset impairment criterion for attention deficit/hyperactivity disorder (ADHD) required in the "Diagnostic and Statistical Manual of Mental Disorders-IV" (DSM-IV) complicates identification of new and known child and adolescent cases later in life. Methods: A birth-records-based…

Background: Few studies have investigated functional and behavioural variables of Cornelia de Lange Syndrome (CdLS) in a large sample of individuals. The aim of this study is to provide greater insight into the clinical, behavioural and cognitive characteristics that are associated with CdLS. Methods: In total, 56 individuals with CdLS…

A survey interviewed parents of 77 children with severe to profound hearing loss while attending an educational program at an Illinois state residential school. The children had lower ages of identification than those reported in national studies and in an early study in Illinois. Delays in early intervention are discussed. (Contains references.)…

This review of research on attention deficit hyperactivity disorder (ADHD) indicates that standard diagnostic criteria are overly inclusive when applied to young children, with only half of impulsive toddlers fitting the criteria for ADHD at later ages. Accurate diagnosis depends on an evaluation of behaviors, child temperament, parent-child…
