FIAT Research

On this page you will find articles and assessment for the Functional Idiographic Assessment Template (FIAT) system and Interpersonal Relationships Questionnaire (or FIAT-Q). You will also find the Functional Assessment of Skills for Interpersonal Therapists (FASIT) system.

These are designed to be used with Interpersonal Behavior Therapy, Functional Analytic Psychotherapy, or any intervention with an interpersonal focus.

The FIAQ-Q manuscript shows the psychometric properties including test retest reliability and validity indices. The reference for the article is:

Darrow, S. M., Callaghan, G. M., Bonow, J. T., & Follette, W. C. (in review). The Functional Idiographic Assessment Template- Questionnaire (FIAT-Q): Initial psychometric properties. Submitted to Journal of Contextual Behavioral Sciences.

There is also a short form of the interpersonal relationships questionnaire (FIAT-Q-SF) that was developed out of this research (described in the article). The items are all taken from the full FIAT-Q and represent a different factor structure of the FIAT-Q with fewer items.

While the psychometrics of the scale are based on a person taking the scale all at once, it is intended that therapists or researchers take subscales out (either from the full FIAT-Q or the short form; e.g., Class A from full form) to use as they best suit the client’s needs.

Please contact me with questions or research ideas (or translations) of the FIAT and its related component. I am always interested in new ways to assess these behaviors and medications to these approaches to functional assessment. You can reach me at
