Research suggests that, by itself or as an adjunct to pharmacotherapy, cognitive-behavioral therapy (CBT) involving exposure with response prevention (ERP) is an effective treatment for Obsessive-Compulsive Disorder (OCD). However, there is a shortage of clinicians trained in this form of therapy. Although many psychodynamic clinicians treat individuals with OCD using traditional therapy that may assist them with their relationships, there is little evidence that such treatment is effective in ameliorating the OCD symptoms. As there is a clear need for more clinicians trained in CBT for OCD, it may be possible for practitioners trained in psychodynamic or other modalities to learn ERP. Such cross-theoretical training involves a number of challenges. These include the therapist's own anxiety about ERP, understanding resistance, and reconsidering therapeutic boundaries. The first author describes his experiences as a psychodynamically-trained psychologist venturing into ERP in an attempt to demonstrate that although there are barriers they are not insurmountable.
