Facets of experiential avoidance differentially predict engagement in a contamination-based behavioral approach task

Experiential Avoidance (EA) is an unwillingness to experience or remain in contact with unpleasant emotions, thoughts, bodily sensations, or other private experiences (Hayes, Wilson, Gifford, Follette, & Strosahl, 1996). Previous research has found a relationship between EA and Obsessive-Compulsive Disorder (OCD; Twohig, Hayes, & Masuda, 2006a). The current study examined relations among multiple EA facets, contamination concerns, and anxiety, disgust, and engagement during a contamination-relevant behavioral approach task (BAT). Of particular interest was whether any specific EA facets would emerge as predictive of task engagement after controlling for baseline contamination concerns. Results were that Distraction/Suppression, Repression/Denial, and Procrastination significantly predicted task engagement. Although Behavioral Avoidance was correlated with anxiety, disgust, and engagement at the zero-order level, it did not predict task engagement after controlling for baseline contamination concerns. These distinct correlates highlight the importance of measuring EA at the facet level rather than as a unitary construct. Specific EA facets may interfere with engagement in BATs-and by extension, exposure-based treatment efforts-to a greater extent than others. Augmentations aimed at decreasing the use of distraction and suppression may improve treatment response in the context of exposure-based treatment for OCD.
