This study aims to investigate the validation of the Rapid Interactive Screening Test for Autism in Toddlers (RITA-T) in Turkish toddlers between 18 and 36 months of age. Children aged 18-36 months were referred to the department of child psychiatry for concerns of autism spectrum disorder, language disorder, developmental delay, and typically…

This study examined the new parent-report assessment's reliability and validity, the Eyuboglu Sensory Reactivity Scale (ESRS), in children with ASD. The ESRS was designed to assess the frequency of sensory behaviors in children with ASD. A total of 167 (age 2-18, M?=?6.4±4.1 years, 79.6 % male) children and their families were included. Parents…

The present study examined the relationships between the standardized applied behavior analysis (ABA) direct assessment, the PEAK Comprehensive Assessment (PCA), and established assessments commonly used in educational and clinical settings, including the Childhood Autism Rating Scale - Third Edition (CARS-3), the PDD Behavior Inventory (PDDBI),…

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…

Objective: Limited time and resources necessitate the availability of accurate, inexpensive and rapid diagnostic aids for Autism Spectrum Disorder (ASD). The Autistic Behavioural Indicators Instrument (ABII) was developed for this purpose, but its psychometric properties have not yet been fully established. Method: The clinician-rated ABII, the…

The Pervasive Developmental Disorder Behavior Inventory is a questionnaire designed to aid in the diagnosis of pervasive developmental disorders or autism spectrum disorders. The Pervasive Developmental Disorder Behavior Inventory assesses adaptive and maladaptive behaviors associated with pervasive developmental disorders and provides an…

The author reviews Childhood Autism Rating Scale-Second Edition (CARS2), a useful tool for supporting the diagnostic process and for forming intervention recommendations once a diagnosis has been made. CARS2 consists of three rating forms designed to identify symptoms associated with autism spectrum disorders (ASD). Published in 2010, the CARS2…

The purpose of this study was to test the psychometric properties of the Caregiver Strain Questionnaire (CGSQ) among caregivers of children with autism. The CGSQ was originally developed to assess burden experienced by parents of children and adolescents with serious emotional and behavioral disorders. Study data was collected from 304 primary…

The development and psychometric characteristics of the Minnesota Visual Autism Symptom Scale (MN-VASS) was described. The relationship between the literature surrounding autism symptoms, the diagnostic criteria for autism, and the resulting content of subscales was presented. Item analyses were conducted using item total correlations. All of the…

A Spanish translation of the Autism Detection in Early Childhood (ADEC-SP) was administered to 115 children aged 15-73 months in Mexico. In Phase 1, children with Autistic Disorder (AD), a non-Pervasive Developmental Disorder (PDD) diagnosis or typical development were assessed with the ADEC-SP by a clinician blind to the child's diagnostic…

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…

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…

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 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.…

The review examines five measures designed to assess autistic symptomatology: Rimland's Diagnostic Checklist for Behavior-Disturbed Children, the Behavior Rating Instrument for Autistic and Atypical Children, the Behavior Observation Scale for Autism, the Childhood Autism Rating Scale, and the Autism Behavior Checklist. Available studies of…
