The Comprehensive assessment of Acceptance and Commitment Therapy processes (CompACT) was developed to overcome some of the limitations of existing ACT process measures and to provide a fuller assessment of psychological flexibility. However, at 23 items, the CompACT is relatively lengthy and is therefore not ideally suited to all potential use-cases. In this presentation, we describe the development of a short-form version of the CompACT that is more apt for use when low-burden, frequent, and/or repeated measurement of psychological flexibility is required. We will outline the process of deriving the short-form, including the psychometric, theoretical, and qualitative steps taken, and present new validation data (N= 579) for this abbreviated, 8-item version of the CompACT (the CompACT-8). These data indicate that the CompACT-8 is psychometrically robust, with good internal reliability, concurrent and convergent validity, and good model fit with the previously-defined three-factor structure of the original CompACT. The additional use-cases of the new abbreviated measure will be discussed.
