This study investigated the psychometric properties of the Autism Mental Status Examination (AMSE) in a Brazilian sample of children and adolescents with autism spectrum disorder (ASD). A sample of 260 children and adolescents, comprising 56 (21.5%) females and 204 (78.5%) males, was assessed. The participants were submitted to both the childhood…

The Childhood Autism Rating Scale (CARS), (Schopler et al. in J Autism Dev Disord 10(1):91-103, 1980) is a 15-item observation-based rating scale that yields a total score reflective of autism symptom severity. This study investigated the factor structure of the CARS in a sample of 2-year-old children with DSM-IV-TR (American Psychiatric…

Strategies for the early detection of autism spectrum disorders (ASD) in people with intellectual developmental disorder (IDD) are urgently needed, but few specific tools have been developed. The present study examines the psychometric properties of the EVTEA-DI, a Spanish adaptation of the PDD-MRS, in a large randomized sample of 979 adults with…

This study evaluated the predictive validity of the Autism Detection in Early Childhood (ADEC; Young, Autism detection in early childhood: ADEC. Australian Council of Educational Research, Camberwell, VIC 2007) and a well-established screening tool, the Childhood Autism Rating Scale (CARS; Schopler et al. The childhood autism rating scale (CARS).…

The autism spectrum disorder (ASD) diagnostic classifications, according to the DSM-5, include a severity rating. Several screening and/or diagnostic measures, such as the autism diagnostic and observation schedule (ADOS), Childhood Autism Rating Scale (CARS) and social responsiveness scale (SRS) (teacher and parent versions), include an…

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…

Diagnoses for autism based on the Autism Diagnostic Interview-Revised (ADI-R) and the Childhood Autism Rating Scale (CARS) were examined for 83 individuals with suspected autism. Individuals diagnosed with autism based on only one system were significantly younger than those with diagnoses based on both systems. Comparison for possible gender…

Children (n=132), ages 1-16, were diagnosed for autism using the criteria in the International Classification of Diseases (ICD-10), Childhood Autism Rating Scale, Autistic Behavior Checklist, and third and fourth editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM). Agreement of the DSM-IV and ICD-10 with the other…

Analyses of the internal consistency of three autism scales--the Autism Behavior Checklist (ABC), the Real Life Rating Scale (RLRS), and the Childhood Autism Rating Scale (CARS)--were conducted with 34 children with pervasive developmental disabilities. Good internal consistency was found for the CARS. Adequate full-scale consistency was found for…

The study investigated the effectiveness of three instruments in discriminating 20 autistic from 20 trainable mentally retarded children (ages 3-12): Autism Screening Instrument for Educational Planning (ASIEP), Childhood Autism Rating Scale (CARS), and Diagnostic Checklist for Behavior Disordered Children. The CARS and ASIEP provided for a…

Testing of the validity and reliability of the Childhood Autism Rating Scale for autistic adolescents found the measure clearly discriminated between groups of autistic and non-autistic adolescents though it did not discriminate younger from older autistic subjects. (Author/DB)

This study compared DSM-III-R (Diagnostic and Statistical Manual III, Revised), Childhood Autism Rating Scale, and clinical diagnoses of 138 admissions to a program for diagnosis and treatment of autistic and related communication-handicapped individuals. Results indicated generally high agreement on the diagnosis of autism, with DSM-III-R…

Fifteen children (ages 4-13) with psychotic symptoms were compared to 15 children with autism using the Ritvo-Freeman Real Life Rating Scale and the Childhood Autism Rating Scale. Psychotic individuals were rated as having better language and social skills; autistic persons had more difficulty adapting to new situations. (Author/JDD)

A Japanese translation of the Childhood Autism Rating Scale was used with 167 developmentally disabled children under age 16. Total score demonstrated a satisfactory level of taxonomic validity and discriminated infantile autism and other pervasive developmental disorders from mental retardation alone. A satisfactory concurrent validity on the…

This study assessed the interrater reliability of a Swedish version of the Childhood Autism Rating Scale (CARS), an instrument for screening and diagnosis of autism. The CARS was used for rating autistic behavior by two investigators in 25 children. Results indicated fair to excellent agreement. Aspects of validity and reliability are discussed.…
