A one year follow-up is reported of a randomized clinical trial with generalized anxiety disorder (GAD) in which the main comparison was between analytic psychotherapy (AP) and cognitive therapy (CT), each delivered at weekly or fortnightly intervals over a six month period. CT was found to be significantly more effective than AP. However, GAD is a chronic and relapsing condition and follow-up data are needed to assess the durability of improvement and the possibility that the benefits of analytic psychotherapy may be more apparent over the longer term. Data were collected in three areas: (1) symptomatology and overall improvement; (2) medication usage and contact with GPs; and (3) attitudes to therapy. CT was clearly superior to AP on the main outcome measures and only a minority of AP patients made significant improvements. CT but not AP was associated with significant reductions in medication usage, and patients receiving CT were generally more positive about treatment received. Differences between treatments were less evident in the less intensive treatment condition where overall results were relatively poor. The most positive outcomes were achieved in the more intensive CT condition in which approximately two-thirds of patients achieved clinically significant improvements.
