The Diagnostic Adaptive Behavior Scale™ (DABS) is now available. The DABS is an instrument for assessing the adaptive behavior of people between the ages of 4 and 21 for the purpose of determining whether the person meets the second criterion for a diagnosis of intellectual disability (ID). The second criterion is a significant limitation in adaptive behavior as expressed in conceptual, social, and practical adaptive skills. The DABS is a norm-referenced instrument that uses data obtained from an interview with a respondent who knows the person very well.
This product is the user’s manual for the DABS and includes a sample copy of the interview form. Bundle packs of interview forms are also available in the bookstore.
The DABS has a number of unique features that support its precision, accuracy, validity, and credibility in making a diagnosis of ID, including:
- Measures some aspects of adaptive behavior that are not currently measured by other standardized instruments, including naiveté, gullibility, and technology-based skills.
- Designed using item response theory (IRT) and reliably measure individual performance levels across the continuum of adaptive skills and ages.
- Provides precise information to assist users in determining significant limitations in adaptive behavior.
Because the DABS relies on IRT, it cannot be scored by hand, and requires a specially developed computer program for scoring. AAIDD’s online scoring platform for the DABS can be easily used for a nominal fee, and it provides reports for each assessment scored. The scoring platform is available through www.aaidd.org/dabs
. A complimentary, single-use voucher code for the scoring platform is included with the purchase of each manual.
