Brief Summary:
The objective of this study is to learn how to improve treatment for clients who are working hard in treatment at the McLean Hospital Obsessive Compulsive Disorder Institute (OCDI), but who are not making the progress that would typically be expected. Therefore, the investigators will be comparing the performance of such clients in a treatment as usual (TAU)-Exposure and Response Prevention (ERP) session with their performance in an Acceptance and Commitment Therapy (ACT)-focused ERP session that follows an ACT booster session. The investigators hypothesize that clients will perform significantly better in the ACT-focused ERP session than they will in the TAU-ERP session. More specifically, the investigators hypothesize that clients and an independent rater will report that in the ACT-focused ERP session, clients performed significantly fewer rituals and/or avoidance behaviors, exerted significantly more effort, had significantly less difficulty getting started with the ERP, were significantly less influenced by their uncomfortable thoughts/feelings, were significantly more willing to experience discomfort, were significantly more focused on working towards what is important to the client. The investigators also hypothesize that an independent rater will rate clients as significantly more compliant with the ACT-focused ERP session than with the TAU-ERP session. The investigators also hypothesize that clients will rate the ACT-focused ERP session as significantly more preferable and acceptable than the TAU-ERP session, and that they will report being significantly more willing to do the ACT-focused ERP session again.
