Exposure and Response Treatment. Exposure treatment purposefully generates anxiety by exposing the patient repeatedly to the feared object or situation, either literally or using imagination and visualization. It uses the most fearful stimulus first. (This differs from the desensitization process because it does not involve relaxation or a gradual approach to the source of anxiety.)
Exposure treatments are usually either known as flooding or graduated exposure:
- Flooding exposes the person to the anxiety-producing stimulus for as long as 1 - 2 hours.
- Graduated exposure gives the patient a greater degree of control over the length and frequency of exposures.
In both cases, the patient experiences the anxiety over and over until the stimulating event eventually loses its effect. Combining exposure with standard cognitive therapy may be particularly beneficial. This approach has helped certain patients in most anxiety disorder categories, including post-traumatic stress disorder.
Modeling Treatment. Phobias can often be treated successfully with modeling treatment:
- The therapy typically uses an actor who approaches an anxiety-producing object or engages in a fear-provoking activity that is similar to the patient's specific problem. Either a live or videotaped situation may be used, although the live model is considered to be more effective.
- The patient observes this event and tries to learn how to behave in a comparable manner.
Other Forms of Psychotherapy
Other forms of psychotherapy, commonly called emotion-based psychotherapy (EBT) or "talk" therapy, deal more with childhood roots of anxiety and usually, although not always, require longer treatments. They include interpersonal therapy, supportive psychotherapy, attention intervention, and psychoanalysis. All work is done during the sessions. Some experts believe that such therapies might be more useful for generalized anxiety, which may require more sustained work to process and recover from early traumas and fears. Studies suggest that although emotion-based psychotherapies are not as effective as cognitive-behavioral therapy (CBT) in treating panic disorders, patients tend to stay in longer in EBT than in CBT. Some experts suggest adding elements of EBT to the usual CBT and medication treatments.
Alternative Procedures
Biofeedback. Biofeedback uses special sensors that allow patients to recognize anxiety states by changes in specific physical functions, such as changes in pulse rate, skin temperatures, and muscle tone. Eventually they learn to modify these changes, which in turn helps relieve anxiety.
Breathing Retraining. Breathing retraining techniques may help reduce the physical effects of anxiety. For example, hyperventilation is one of the primary physical manifestations of panic disorders. This involves rapid, tense breathing, resulting in chest pain, dizziness, tingling of the mouth and fingers, muscle cramps, and even fainting. By practicing measured, controlled breathing at the onset of a panic attack, patients may be able to prevent full attacks.
