The heterogeneous nature of Autism Spectrum Disorder (ASD) makes accurate diagnosis challenging. Best practice assessments in schools can open pathways to appropriate interventions and educational placements for those with ASD, as well as help identify a student's strengths. There are various tools used in school settings to assess autism. In this…

Although symptoms of autism are present early in life and early diagnosis can lead to better outcomes, there is a dearth of validated caregiver-report interviews designed for children under the age of 3 years. We developed the Toddler Autism Symptom Inventory, a semi-structured interview designed to assess the presence and absence of skills and…

Screening for autism spectrum disorder is the first step toward early detection and diagnosis, thereby impacting the likelihood of children accessing early intervention and, importantly, improving long-term outcomes. This systematic review aimed to (a) establish a clear baseline of autism spectrum disorder screening tools currently used throughout…

The aim of the present study was to establish diagnostic validity of the new algorithm of the Autism Diagnostic Observation Scale, the ADOS-2, to differentiate between ASD and other clinically relevant psychiatric and developmental disorders in a large German sample. Validity of ADOS and ADOS-2 diagnostic algorithms was established in 826…

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;…

To determine the best discriminative items for identifying young children with autism spectrum disorders (ASD), we conducted a secondary analysis using longitudinal cohort data that included the Japanese version of the 23-item modified checklist for autism in toddlers (M-CHAT-JV). M-CHAT-JV data at 18 months of age and diagnostic information…

The Wechsler Intelligence Test for Children -- Fifth Edition (WISC-V) is a comprehensive intellectual ability assessment for children. The WISC-V was developed over the course of five years by an expert team including doctoral-level scientists and clinicians and an advisory panel, who provided expert advice about intellectual ability testing,…

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,…

Rehabilitation professionals working with students with disabilities and the families of those students face unique challenges in providing inclusive services to special education student populations. There needs to be a focus on adaptive teaching methods that provide quality experience for students with varying disabilities to promote student…

No feasible screening instrument is available for early detection of children with autism in Taiwan. The existing instruments may not be appropriate for use in Taiwan due to different health care systems and child-rearing cultures. The purpose of this study was to develop and test a screening questionnaire for generic autism. The initial 18-item…

The rise in the prevalence of autism creates a need for a reliable and valid measure of attitudes towards autism. The current study describes the development of a brief 16-item measure of Societal Attitudes towards Autism (SATA) that exhibits sound psychometric properties and has a demonstrated ability to discriminate between expert and general…

Autism Spectrum Disorders (ASD) is a topic receiving great attention from researchers and clinicians in the field. However, many of these studies focus on children or adults, with research on infants and toddlers evincing ASD being virtually non-existent. Even more scant is information pertaining to the assessment of symptoms of comorbid…

The benefits of early intervention for very young children with autism are now well established. Hand and hand with these interventions is the necessity of psychometrically sound diagnostic tools. Not only should these tools be instrumental in differentiating developmentally delayed and other at risk infants. These measures should also be…

There has been a dramatic worldwide increase in reported cases of autism over the past decade. Autism is much more prevalent than previously thought, especially when viewed as a spectrum of disorders (autism spectrum disorders; ASD). School-based professionals are now more likely to be asked to participate in the screening and identification of…

Agreement between the Autism Diagnostic Interview-Revised (ADI-R) and two brief scales completed by parents was 93.1% for the Checklist for Autism Spectrum Disorder (CASD) and 89.7% for the Social Responsiveness Scale (SRS) in a sample of adolescents with suspected autism spectrum disorders. Our study is consistent with others showing that brief…
