The diagnostic adaptive behavior scale: evaluating its diagnostic sensitivity and specificity.

Balboni et al. (2014) tested the Diagnostic Adaptive Behavior Scale (DABS). They asked if it could spot intellectual disability (ID) in kids and young adults.

The team gave the 60-item caregiver interview to 244 people. Ages ranged from 3 to 25. Some had ID. Some were neurotypical.

The DABS hit 81–98 % sensitivity and 89–91 % specificity. That means it caught most true ID cases and rarely gave false positives.

In plain words, the scale is quick, cheap, and accurate for diagnosis.

Oliver et al. (2002) and Hastings et al. (2001) refined the Developmental Behavior Checklist for emotional problems in ID. DABS follows the same checklist idea, but targets adaptive skills instead of psychopathology.

Wuang et al. (2009) used Rasch methods to trim the BOT-2 motor test for ID. Giulia et al. used similar psychometric steps to shorten and toughen the DABS.

Hirota et al. (2018) reviewed autism screeners for ages 4+. They did not include adaptive scales like DABS, so the papers do not clash; they simply cover different constructs.

If you evaluate for ID, swap in the DABS instead of older long forms. You get a 15-minute caregiver interview with clear cut-offs. Use the scores to document adaptive deficits for diagnosis or funding. Pair the result with cognitive testing and you have a solid, evidence-based report ready for Monday morning.
