title: A pilot randomized trial of metacognitive therapy vs applied relaxation in the treatment of adults with generalized anxiety disorder.
abstract: Metacognitive Therapy (MCT) and Applied Relaxation (AR) were compared in a pilot treatment trial of generalized anxiety disorder (GAD). Twenty outpatients meeting criteria for DSM-IV-TR GAD were assessed before treatment, after treatment and at 6 m and 12 m follow-up. The patients were randomized and treated individually for 8-12 weekly sessions. There was no drop-out from MCT and 10% at 6 m follow-up from AR. At post-treatment and at both follow-up points MCT was superior to AR. Standardized recovery rates for MCT at post-treatment were 80% on measures of worry and trait-anxiety compared with 10% following AR. At 6 m follow-up recovery rates for MCT were 70% on both measures compared with 10% and 20% for AR. At 12 m follow-up recovery rates for MCT were 80% (worry) and 60% (trait-anxiety) compared with 10% and 20% following AR. The recovery rates for MCT are similar to those obtained in an earlier uncontrolled trial (Wells & King, 2006). The effect sizes and standardized recovery rates for MCT suggest that it is a highly effective treatment.
