A randomized controlled trial of cognitive therapy for bipolar disorder: focus on long-term change.

BACKGROUND: This study reports the outcome of a randomized controlled trial of cognitive therapy (CT) for bipolar disorder. The treatment protocol differed from other published forms of CT for bipolar disorder through the addition of emotive techniques. METHOD: Fifty-two patients with DSM-IV bipolar I or II disorder were randomly allocated to a 6-month trial of either CT or treatment as usual, with both treatment groups also receiving mood stabilizers. Outcome measures included relapse rates, dysfunctional attitudes, psychosocial functioning, hopelessness, self-control, and medication adherence. Patients were assessed during treatment by independent raters blind to the patients' group status. RESULTS: At posttreatment, patients allocated to CT had experienced less severe depression scores (Beck Depression Inventory and Montgomery-Asberg Depression Rating Scale) and less dysfunctional attitudes. After controlling for the presence of major depressive episode at baseline, there was a statistical trend toward a greater time to depressive relapse (p=.06) for the CT group. At 12-month follow-up, the CT group showed a trend toward lower Young Mania Rating Scale scores and improved behavioral self-control. The Clinical Global Impressions-Improvement scale, comparing the 18 months prior to treatment to the severity of illness status at follow-up, showed a substantial difference between groups in favor of CT. CONCLUSION: Our findings corroborate previous bipolar disorder research in demonstrating the value of CT, particularly immediately post-treatment, and indicate some continuation (albeit diminishing) of benefits in the succeeding 12 months. These findings suggest that psychological booster sessions may be crucial for maintaining the beneficial effects of cognitive therapy.

Schema-focused cognitive therapy for bipolar disorder: reducing vulnerability to relapse through attitudinal change.

OBJECTIVE: Acceptance of, and adaptability to illness, are major determinants of adherence to treatment and functional recovery. This paper addresses the major psychosocial factors associated with bipolar disorder and the role of psychological interventions in symptom management and adaptability to the illness experience. A new model is presented highlighting the role of developmental experiences and temperament in determining reactions to bipolar disorder. The authors propose that by addressing reactions to the illness experiences and effects on self-concept through schema-focused cognitive therapy, functional recovery is more likely to occur among those patients functioning below expectation. METHOD: A systematic review of the current literature including an Index Medicus/MEDLINE search was conducted, focusing on risk factors, cognitive vulnerabilities and triggers associated with bipolar disorder. Psychological treatments available for the treatment of bipolar disorder are reviewed and details of a novel schema-focused cognitive model for this condition are presented. Traditional models of adaptation to chronic illness are outlined and incorporated into the proposed model. Schema-focused cognitive therapy is proposed as an approach to help patients reduce cognitive vulnerability to relapse in addition to adopting effective mood management strategies. RESULTS AND CONCLUSIONS: There is a need for psychological treatments which reduce the risks associated with poor functionality in patients with bipolar disorder. Schema-focused cognitive therapy specifically targets the temperament, developmental experiences and cognitive vulnerabilities that determine adjustment to illness. This proposed treatment, combined with pharmacotherapy, may offer new psychotherapeutic options for the future.
