Long-term outcome of panic disorder and social phobia.

The question is addressed as to whether cognitive-behavior treatment delivered as a routine service in a specialist clinic is effective in the long term. Of 124 consecutive patients completing treatment for panic disorder or social phobia, 93 were assessed an average of 2 years following treatment. The treatment produced significant improvement in measures of symptoms, avoidance, and disablement during treatment and further significant improvement during the follow-up. A quarter of participants no longer met diagnostic criteria, had not sought further treatment, and their anxiety had not troubled them since treatment. These findings, although not showing the large treatment effects reported from controlled outcome research, support the effectiveness of cognitive-behavioral interventions in routine care.
