In overcoming OCD, the use of Exposure and Response Prevention (ERP) is absolutely essential. But CBT is often mentioned as the treatment of choice. So, what is the difference? Let me explain:.
- Behavior Therapy, BT, starting using ERP in the late 1950s, and was the first treatment that showed consistent success for OCD.
- Cognitive Therapy, CT, worked well with Depression, but initially showed poor results in treating Anxiety Disorders.
- Cognitive Behavior Therapy, CBT was born when the CT therapists added the BT technique of ERP to their regimen.
- Studies show that BT and CBT work equally for treating OCD,
- So there is little evidence that the Cognitive part of CBT is needed.
Even Aaron Beck, the “father” of CT and CBT, emphasizes the importance of using ERP when treating OCD. In his book, “Cognitive Therapy for Anxiety Disorders” he states:
….exposure is perhaps the most powerful behavioral intervention for fear reduction. Whenever possible, employ this therapeutic tool in the treatment of anxiety disorders. p. 247
Cognitive interventions should be introduced in the early sessions with with frequent and intense exposure-based behavioral exercises employed throughout the course of the treatment. p. 486
Clients should engage in daily exposure between sessions. p. 246
Unfortunately, in many CBT training programs, the emphasis is on learning the cognitive techniques, and less on the behavioral techniques. So, if you seek treatment with a CBT therapist, it very important that you enquire how experienced the person is in using ERP.
