Now available! One of the most widely used instruments for the assessment of autism spectrum disorder in the world, the GARS assists teachers, parents, and clinicians in identifying autism in individuals and estimating its severity.

Third edition is revised and improved

  • Items and subscales reflect DSM-5™ diagnostic criteria for autism spectrum disorder.
  • Items are grouped into three subscales—Stereotyped Behaviors, Communication, and Social Interaction.
  • Normative data (N = 1,859) were collected in 2010 and 2011. Demographic characteristics of the normative sample are keyed to those reported by U.S. Bureau of the Census, 2011.

Gathers diagnostically significant information

  • Fifty-six clearly stated items describe the characteristic behaviors of persons with autism and are grouped into six subscales: Restrictive, Repetitive Behaviors, Social Interaction, Social Communication, Emotional Responses, Cognitive Style, and Maladaptive Speech.
  • An interpretation guide allows the examiner an easy and efficient method for assessing the probability of autism spectrum disorder and the severity of the disorder.

Exhibits sound psychometric characteristics

  • Internal consistency reliability coefficients exceed .85 for the subscales .93 for the Autism Indexes; test-retest reliability coefficients exceed .80 for subscales and .90 for the Autism Indexes.
  • Correlations of the GARS-3 scores with those of other well-known diagnostic tests for autism are large or very large in magnitude.
  • Binary classification studies indicate that the GARS-3 is able to accurately discriminate children with autism spectrum disorder from children without autism (i.e., sensitivity = .97, specificity = .97, ROC/AUC = .93).
