Overview

The Adaptive Behavior Diagnostic Scale (ABDS) is an interview-based rating scale that assesses the adaptive behavior of individuals between the ages of 2 through 21 years.

  • Helps to establish the presence and the magnitude of adaptive behavior deficits
  • ABDS scores are compatible with state and federal special education classification systems and consistent with the DSM-V and American Association Intellectual and Developmental Disorders (AAIDD) definitions of intellectual disability
  • May be used to assess the adaptive behavior of individuals with or suspected of having intellectual disability, Autism Spectrum Disorder, learning disabilities, mental or behavioral health condition or other similar concerns

Normative Data

The internal consistency reliability coefficients of the domain and composite scores were all above .90 for all age and disability groups. A study of the diagnostic accuracy, a highly rigorous validity technique, is reported with regards to sensitivity (.85), specificity (.99), classification accuracy (.98), and receiver operating characteristic/area under the curve (.99).

Norms for the ABDS are based on a nationally representative sample of 1,061 children and adolescents who reside in the U.S.
