Problem/Condition: Autism spectrum disorders (ASDs) are a group of developmental disabilities characterized by atypical development in socialization, communication, and behavior. ASDs typically are apparent before age 3 years, with associated impairments affecting multiple areas of a person's life. Because no biologic marker exists for ASDs,…

Background: For early detection of autism, it is difficult to maintain an efficient level of sensitivity and specificity based on observational data from a single screening. The Extraction and Refinement (E&R) Strategy utilizes a public children's health surveillance program to produce maximum efficacy in early detection of autism. In the…

This study examines the results of the Alternative Identification and Reporting (AIR) program, which promoted the nonuse of disability labels for students receiving special education under the Individuals with Disabilities Education Act (i.e., students who would previously have been identified as having an emotional/behavioral disorder, specific…

Background: The Social Communication Questionnaire (SCQ), formerly the Autism Screening Questionnaire (ASQ), is based on a well-validated parent interview, the Autism Diagnostic Interview (ADI). It has shown promise as a screening measure for autism spectrum disorders (ASDs) in a research-referred older sample, though recent studies with younger…

Epidemiological studies indicate a worldwide increase in the prevalence of autism spectrum disorders (ASDs) over the past decade. ASDs are no longer considered rare conditions. Although the reason(s) for this rise are uncertain, research indicates that specialised intervention at an early age is vital for optimising the outcomes of children with…

Diagnosing autism and PDD-NOS at very early ages has become a major priority in the field of mental health. More recently, researchers have also come to realize the importance of identifying co-occurring conditions of psychopathology in this population. In the present study, 309 children between 17 and 37 months of age who had been identified as…

Behavioral symptoms of comorbid psychopathology of 651 children 17-37 months of age who were at risk for developmental disabilities were studied using the BISCUIT-Part 2. In Study 1, norms and cutoff scores were established for this new scale on this sample. In Study 2, frequency of response on the 52 items measured was reported. Problems in…

Diagnosis of autism spectrum disorder (ASD) is often delayed in high-functioning children with milder and more varied forms of ASD. The substantial overlap between ASD and other psychiatric disorders is thought to contribute to this delay. This study examined the endorsement of DSM-IV-TR diagnostic criteria for ASD based on semi-structured parent…

The number of children with autism served in early intervention or the public school system appears to be growing at an alarming rate. This article provides a basis for understanding this dramatic increase. In addition, the authors present a brief overview of the characteristics of autism, research on early behavioral indicators of infants and…

Recent prevalence rates for autism spectrum disorders (ASDs) are now estimated at about 1 in 110 children in the U.S. Increases in public awareness and research funding in response to the growing numbers of children and adults with this disorder have led to numerous important scientific advances over the last several years. Nevertheless, because…

This article describes the Pre-Linguistic Autism Diagnostic Observation Schedule, a semistructured observation scale designed for diagnosis of young children suspected of having autism. Reliability studies have been positive. Comparison of scores to judgments of clinical teams indicates that the schedule discriminates between autistic and…

Students with a hearing loss often have an additional disability. Although the number of deaf students with multiple disabilities is growing, research on this population has significantly decreased over the past quarter-century. The article reviews the literature on identification and placement of deaf students with multiple disabilities,…

The authors describe their methods for establishing the presence or absence of the fragile-X chromosome and discuss some of the clinical implications of their findings in relation to the clinical diagnosis of autism. (SW)

Autism awareness is spreading like wildfire. Diagnoses have increased at an astounding rate. The statistic most often quoted is that 1 child in 150 has autism. As if the high rate of autism diagnoses were not worrisome enough, many doctors are not properly trained, or kept up to date, on how to detect autism at the earliest possible age. In many…

This review examines published hearing/review and court decisions concerning autism eligibility in educational settings in relation to empirically supported best practices in the assessment of autism. Thirteen cases were identified for inclusion in the review. In general, results indicated that hearing/review officers and judges neither relied…
