Abstract

Generalized Anxiety Disorder (GAD) is one of the most common anxiety disorders. It has been reported that psychological treatments like Cognitive-Behavioral Therapy (CBT) is effective for patients with GAD. The purpose of the present research was to investigate the effectiveness of CBT on Quality of Life (QOL) and worry in patients with GAD. A sample of 30 patients with GAD who had been referred to psychiatry offices in Isfahan, Iran were selected and assigned into an experimental group (n=15) and a control group (n=15) randomly.  The experimental group received CBT in 8 weekly sessions. All participants completed the World Health Organization Quality Of Life-Brief (WHOQOL-BREF) questionnaire and the Penn State Worry Questionnaire (PSWQ) at pretest, posttest and follow up. The results of MANCOVA showed that the mean scores of QOL in the experimental group was significantly higher than the control group at the posttest and follow up (P<0.05) and the mean scores of worry in the experimental group was significantly lower than the control group at the posttest and follow up (P<0.05) It is concluded that CBT can be applied for the patients with GAD as a useful psychological treatment. In general, CBT can improve QOL and decrease worry in patients with GAD.
