A Two Year Follow up Study of Group Metacognitive Therapy for Depression in Norway

Major depression is predicted to become the single leading cause of disease burden in 2030 and is associated with premature death [1]. Cognitive-behavioral therapy (CBT) is a highly recommended treatment for depression with proven efficacy [2-4], but only 40–58% of patients recover and only between one-third and one-quarter remain so 18 months after treatment [5-7]. Metacognitive therapy (MCT) is based on the metacognitive model for emotional disorder and may address this limitation by targeting core mechanisms involved in the development and maintenance of depression [8,9]. Given the recurrent and persistent nature of depression, an important test of psychological treatments is the need to demonstrate stability of long-term therapeutic effects which has yet not been established for group MCT for depression.
