Cognitive therapy versus applied relaxation as treatment of generalized anxiety disorder.
Cognitive therapy (CT) and applied relaxation (AR) as treatments of generalized anxiety disorder (GAD) were compared in a sample of 45 patients of a community mental health center, randomly allocated to condition. Patients were assessed before and after a 12-session treatment, and at one and six months follow-ups. There was a 20% drop out from CT and 15% from AR (NS), with some drop outs being considerably improved. Both completers and intention-to-treat analyses revealed that both treatments were effective (ESs of composite and specific measures ranging from 0.53 to 1.14). At one-month follow-up AR tended to do better than CT, with CT catching up with AR at six months. Recovery rates and proportions of patients showing reliable change were comparable to other studies on AR and CT, with 55% of CT and 53.3% of AR patients recovered on the STAI-trait at six-month follow-up. These results confirm that both CT and AR are effective treatments for GAD, and also that there is still room for improvement.
