Comparison of Scores on the Checklist for Autism Spectrum Disorder, Childhood Autism Rating Scale, and Gilliam Asperger’s Disorder Scale for Children with Low Functioning Autism, High Functioning Autism, Asperger’s Disorder, ADHD, and Typical Development

Abstract

Reliability and validity for three autism instruments were compared for 190 children with low functioning autism (LFA), 190 children with high functioning autism or Asperger's disorder (HFA), 76 children with attention deficit hyperactivity disorder (ADHD), and 64 typical children. The instruments were the Checklist for Autism Spectrum Disorder (designed for children with LFA and HFA), Childhood Autism Rating Scale (CARS) for children with LFA, and Gilliam Asperger's Disorder Scale (GADS). For children with LFA or ADHD, classification accuracy was 100% for the Checklist and 98% for the CARS clinician scores. For children with HFA or ADHD, classification accuracy was 99% for the Checklist and 93% for the GADS clinician scores. Clinician-parent diagnostic agreement was high (90% Checklist, 90% CARS, and 84% GADS).

Leveraging 3D Technology for Students with Autism: An innovative university-community collaboration for skill development and vocational exploration

“…All of the students met the minimum cut-off as per the Checklist for Autism Spectrum Disorder for an autism diagnosis. This measure shows high diagnostic agreement and strong convergence with other autism instruments (Mayes et al 2009). Participating students were male and ranged in age from 15 to 18.…”

“…As reported by parents, 97 per cent of students had social problems, 79 per cent exhibited perseveration, 60 per cent engaged in atypical communication and development, and 68 per cent had mood disturbances. These figures were based on indicators from the Checklist for Autism Spectrum Disorder (Mayes et al 2009). All of the students met the minimum cut-off as per the Checklist for Autism Spectrum Disorder for an autism diagnosis.…”

A Systematic Review of Hippotherapy (horseback riding) for Individuals with Autism is the Cognitive Level Considered?

“…The Childhood Autism Rating Scale (CARS) is a widely used behavioral rating scale developed for screening of autism and identify the severity of the disorder. It is, demonstrating strong psychometric properties including good sensitivity and specificity [50][51][52]. It was used by three studies two of them were completed by the research assistance.…”

Brief Report: Excellent Agreement Between Two Brief Autism Scales (Checklist for Autism Spectrum Disorder and Social Responsiveness Scale) Completed Independently by Parents and the Autism Diagnostic Interview-Revised

“…The CASD (Mayes and Calhoun 1999;Mayes et al 2009) consists of 30 items scored as present (either currently or in the past) or absent by the clinician based on a semi-structured interview with the parent, information from the child's teacher or child care provider, observations of the child, and other available records. The CASD is normed on 800 children with autism 1-17 years of age with IQs of 9-146.…”

“…Department of Health and Human Services 2010;Ward-King et al 2010). Autism assessment scales are available that are completed by parents or clinicians in 15 min and have strong psychometric support, such as the Checklist for Autism Spectrum Disorder (CASD, Mayes et al 2009) and the Social Responsiveness Scale (SRS, Constantino and Gruber 2005). However, the Autism Diagnostic Interview-Revised (ADI-R, Rutter, et al 2008) and Autism Diagnostic Observation System (ADOS, Lord et al 2000) continue to be the recommended ''gold standards'' (Constantino and Gruber 2005;Norris and Lecavalier 2010;Ward-King et al 2010).…”
