Functional Assessment Interview Form (FAI)

The Functional Assessment Interview Form (FAI; O’Neill et al., 1997) is a structured interview designed to gather information about a behavior and the circumstances under which it occurs.


The interview consists of 11 sections that help caregivers/teachers describe the behavior, identify antecedents and consequences, and identify medical conditions. The interview also inquires about an individual’s communication skills, successful and unsuccessful teaching strategies and activities; effective reinforcers, interventions previously attempted, and developed hypotheses.
