 Generalized anxiety disorder GAD is a common psychiatric disorder that affects nearly 6.8 million adults in the United States. GAD is characterized by persistent feelings of worry and anxiety that remain even when there is little reason for concern. The excessive worry that people with GAD experience can be so extreme that carrying out activities of daily life becomes difficult. GAD is often accompanied by physical symptoms as well, including muscle aches, nausea, sweating, exhaustion, irritability, frequent urination, and shaking. People with GAD are also at a higher risk for other disorders, including depression and substance abuse, making early treatment of GAD important. Forms of psychotherapy that concentrate on stress management, relaxation techniques, and control of thoughts about anxiety-provoking situations may be effective treatments for people with GAD. This study will evaluate the effectiveness of three adaptive coping treatments, relaxation and self-control desensitization, cognitive behavioral therapy CBT, and a combination of the two, in lessening anxiety in adults with GAD.
