Conceptual and Psychometric Issues in the Assessment of Adaptive Behavior

Abstract

This article discusses three issues in the assessment of adaptive behavior: the clarity of the construct of adaptive behavior, the norm samples for adaptive behavior scales, and the predictive validity of adaptive behavior scales. It is concluded that while the concept of adaptive behavior is still too vague it is at least as well defined as other constructs, such as intelligence. Vast improvements are noted in the standardization properties of major adaptive behavior scales. Finally, it is argued that adaptive behavior assessment lacks clear evidence of predictive validity. A research agenda aimed at improving adaptive behavior assessment is presented.
