Impact of cognitive-behavioral treatment on quality of life in panic disorder patients.

Panic disorder (PD) is associated with significant social and health consequences. The present study examined the impact of treatment on PD patients' quality of life. Patients (N = 156) meeting DSM-III-R (Diagnostic and Statistical Manual of Mental Disorders [3rd ed., rev.]; American Psychiatric Association, 1987) criteria for PD with agoraphobia were randomly assigned to group cognitive-behavioral treatment (CBT) or a delayed-treatment control. An assessment battery measuring the major clinical features of PD as well as quality of life was administered at baseline (Week 0), post-treatment (Week 9) and 6-month follow-up (Week 35). Consistent with previous studies, PD patients displayed significant impairment in quality of life at intake. Compared with delayed-treatment control participants, CBT-treated participants showed significant reductions in impairment that were maintained at follow-up. Consistent with prediction, anxiety and phobic avoidance were significantly associated with quality of life, whereas frequency of panic attacks was not.
