Questions about behavioral function (QABF): a behavioral checklist for functional assessment of aberrant behavior

Functional assessment is a method to identify the relationships between a behavior of interest and an individual's environment. Traditional methods for functional assessment have relied on experimental techniques in which analog sessions are designed to replicate conditions in the individual's environment. However, these techniques can be time-consuming, require advanced training, and rely on the availability of extensive resources in the individual's setting. Development of a brief functional assessment checklist would circumvent these difficulties and meet clinical needs for efficient assessment methods. The current study provides psychometric data for the Questions About Behavioral Function. These data include test-retest, inter-rater, and internal consistency.
