ABDS
Adaptive Behavior Diagnostic Scale

Nils A. Pearson, James R. Patton and Daniel W. Mruzek

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. The primary function of the ABDS is to establish the presence and the magnitude of adaptive behavior deficits. The ABDS scores are compatible with state and federal special education classification systems and consistent with the DSM-V and American Association on Intellectual and Developmental Disorders (AAIDD) definitions of intellectual disability. The ABDS 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.

 
Key Areas Measured:
  • Conceptual Domain: Language, reading, writing, math, reasoning, knowledge, and memory.
  • Social Domain: Empathy, social judgment, gullibility, communication skills, the ability to make and retain friendships, and similar interpersonal capabilities.
  • Practical Domain: Self-management personal care, home living, community use, job responsibilities, money management, recreation, and organizing school and work tasks.
  • Adaptive Behavior Index: A combination of the three domain scores results in a composite score called the Adaptive Behavior Index. This composite is the most reliable score that is generated from administering the ABDS.
