Exposure Therapy for PTSD

By

Updated February 21, 2012

Exposure therapy has been found to effectively address the symptoms of PTSD, as well as in the treatment of other anxiety disorders.

What is Exposure Therapy?

Exposure therapy is considered a behavioral treatment for PTSD. This is because exposure therapy targets learned behaviors that people engage in (most often the avoidance) in response to situations or thoughts and memories that are viewed as frightening or anxiety-provoking. For example, a rape survivor may begin to avoid relationships or going out on dates for fear that she will be attacked again.

It is important to recognize that this learned avoidance serves a purpose. When a person experiences a traumatic event, he may begin to act in ways to avoid threatening situations with the goal of trying to prevent that traumatic experience from happening again. In many ways, this avoidance is a safety-seeking or protective response. However, as this avoidance behavior becomes more extreme, a person's quality of life may lessen. He may lose touch with family or experience difficulties at work or in relationships.

In addition, avoidance can make PTSD symptoms stick around longer or even intensify. That is, because a person is avoiding certain situations, thoughts, or emotions, he doesn't have the opportunity to learn that these situations may not be quite as threatening as they seem. In addition, by avoiding thoughts, memories, and emotions, a person doesn't let himself to fully process those experiences.

The goal of exposure therapy then is to help reduce a person's fear and anxiety, with the ultimate goal of eliminating avoidance behavior and increasing quality of life. This is done by actively confronting the things that a person fears. By confronting feared situations, thoughts, and emotions, a person can learn that anxiety and fear will lessen on its own.

So, how does a person actively confront feared situations, thoughts, and emotions during exposure therapy? A number of methods may be used by a therapist. These are described below.

In Vivo Exposure

In vivo exposure refers to the direct confrontation of feared objects, activities, or situations by a person under the guidance of a therapist. For example, a woman with PTSD who fears the location where she was assaulted may be assisted by her therapist in going to that location and directly confronting those fears (as long as it is safe to do so).

Imaginal Exposure

Imaginal exposure can help a person directly confront feared thoughts and memories. Imaginal exposure may also be used when it is not possible or safe for a person to directly confront a feared situation. For example, it would not be safe to have a combat veteran with PTSD directly confront a combat situation again. Therefore, he may be asked to imagine a feared combat situation that he experienced.

Interoceptive Exposure

Interoceptive exposure was originally designed to treat panic disorder. However, there is evidence that it may be successful in the treatment of PTSD as well. It is designed to help people directly confront feared bodily symptoms often associated with anxiety, such as an increased heart rate and shortness of breath. The therapist may assist this by having a person (in a controlled and safe manner) hyperventilate for a brief period of time, exercise, breath through a straw, or hold his breath.

Finding a Therapist Who Does Exposure Therapy

As indicated previously, exposure therapy has been found to be a very effective treatment for PTSD. In addition, methods for delivering exposure therapy to people is continuing to advance. In particular, some therapists are beginning to use virtual reality technology to help people confront the things they fear most.

Yet, it is important to recognize that some people are hesitant to go through exposure therapy because it might sound scary to confront fears. Exposure therapy is like any other treatment for PTSD. It requires a tremendous commitment and can be difficult at times. A major part of most treatments for PTSD is confronting and connecting with feared situations, thoughts, and feelings. The way in which this is done in each treatment simply differ.

Therefore, it is very important to find the right treatment and therapist for you. You can find out more information about treatment providers in your area who might offer exposure therapy through UCompare HealthCare from About.com, as well as the Anxiety Disorder Association of America.
