Psychological Therapy for OCD is Effective

Psychological therapy for OCD is recognized by both researchers and healthcare providers as effective treatments for reducing the frequency and intensity of symptoms of OCD. Effective psychological therapy for OCD stresses changes in behavior and/or thoughts (sometimes called cognitions). When appropriate, behavioral and cognitive therapy for OCD can be combined with medication to get the best result.

Behavior Therapy for OCD: Facing Your Worst Fears

Although there are a variety of behavioral therapies for treating OCD, almost all focus on exposing you to those things that you fear most such as contamination or the troubling content of an obsessional thought. This exposure provides you with an opportunity to gain new information in hopes of disconfirming your worst fears.

One of the most popular and effective forms of behavior therapy for OCD is exposure and response prevention or ERP. ERP involves exposing you to the anxiety that is provoked by your obsessions and then preventing the use of rituals to reduce your anxiety. This cycle of exposure and response prevention is repeated until you are no longer troubled by your obsessions and/or compulsions.

ERP usually involves 15 to 20 exposure sessions that last about 90 minutes. These sessions usually take place at the therapist’s office, although you are usually asked to practice ERP at home.

While some therapists prefer to begin with exposure to the most feared stimuli (this is sometimes called flooding), others prefer to take a more gradual approach. For example, it is not uncommon to have people begin ERP by simply thinking about being exposed to the things they fear most.

Although behavior therapy is highly effective for about two-thirds of people who complete treatment, there are drawbacks.

  • Behavior therapy involves facing your worst fears; many patients dropout before treatment is complete.

  • Behavior therapy is hard work and requires completing homework in between sessions.

  • Behavior therapy may not be that effective for people who experience primarily obsessions without compulsions.

  • Behavior therapy can be expensive, although your insurance plan may cover all or part of the cost.

Cognitive Therapy for OCD: Opening Your Mind to New Possibilities

Cognitive therapy for OCD is based on the idea that distorted thoughts or cognitions cause and maintain harmful obsessions and compulsions. For example, although the majority of people report experiencing intrusive, and often bizarre, thoughts on a daily basis, if you have OCD you may over inflate the importance or danger associated with such thoughts. You may even believe that by having such thoughts, you increase the likelihood of the feared thought, event or action taking place or being true.

In another example, if you have OCD, you might dramatically overestimate the degree to which you are responsible for a catastrophic event taking place and feel you have to take actions to prevent it.

For instance, you might experience an uncontrollable urge to count or order a particular object to prevent a plane crash. Of course, counting or ordering a particular object couldn’t possibly have any impact on whether a plane crashes or not. This illogical thought pattern is often called magical thinking.

Cognitive therapy involves examining these harmful thought patterns and coming up with plausible alternatives that are more realistic and less threatening. It is not uncommon for you to be unaware of some of the distortions that are present in your thinking and the therapist may help to point these out. Cognitive therapy often integrates elements of behavior therapy. For example, your therapist may have you test out some of the plausible alternatives you have come up with through exposure therapy.

Like ERP, cognitive therapy is usually done over the course of 15 to 20 sessions, although the cognitive therapy sessions are often shorter in duration, lasting 50 to 60 minutes. As with ERP, you are often asked to do homework, which usually comprises keeping a daily journal of your thoughts, as well as keeping track of whether your worst fears actually came true.

Is Psychological Therapy for OCD is Right for Me?

Deciding to engage in behavioral or cognitive therapy for OCD is decision that should be made in consultation with your family doctor, psychiatrist or psychologist as part of your overall treatment plan. In controlled research studies, behavioral and cognitive therapy seem to be equally effective. However, in practice they are often combined for maximum effect where it is referred to as cognitive-behavior therapy.

Before engaging in psychotherapy it may be helpful to ask yourself the following questions:

  • Am I willing to try facing the very things I fear most?

  • Will I be able to finance this on my own or will my insurance cover the costs?

  • Am I willing to put in the time required to participate in weekly sessions for up to 20 weeks.

  • On top of going to a weekly session, I am willing to complete homework assignments in between sessions?

Research shows that the people who have good results with psychotherapy are those who are highly motivated to change and willing to try and put in the commitment required. If you have questions about your readiness to participate in psychotherapy, talk to your doctor or psychologist.

Finally, if you decide to include psychotherapy as part of your overall treatment plan make sure you are comfortable with your therapist. If you feel something is preventing you from having a good working relationship with your therapist, don’t be afraid to bring it up in therapy. A good therapist will be happy you have brought this to his attention and will try to work through these issues with you.
