Overview & Efficacy: Everybody gets anxious. Treatment is called for if the amount of anxiety is out of proportion to the problem or lasts too long. Many methods for helping people reduce and control their anxiety have been shown to be effective. Behavioral techniques include relaxation training, cognitive restructuring, and biofeedback. Any form of biofeedback that helps people become aware of their physiological responses as they become anxious and that helps people learn to relax is apparently at least as effective as any other behavioral technique.
This therapy is rated as efficacious (level 4 on a scale of 1 - 5 with 5 being the best).
