Abstract:McPherson S, Cairns P, Carlyle J, Shapiro DA, Richardson P, Taylor D. The effectiveness of psychological treatments for treatment-resistant depression: a systematic review.
Acta Psychiatr Scand 2005: 1–10. © Blackwell Munksgaard 2005. Objective:
A systematic review of all studies (controlled and uncontrolled) to evaluate psychological interventions with treatment-resistant depression. Method:
A systematic search to identify studies evaluating a psychological intervention with adults with a diagnosis of major depressive disorder who had not responded to at least one course of antidepressant medication. Results:
Twelve studies met inclusion criteria, of which four were controlled and eight uncontrolled. Treatment effect sizes were computable for four studies and ranged from 1.23 to 3.10 with a number of better quality studies demonstrating some improvements in patients following a psychological intervention. Conclusion:
Psychological treatments for depression are commonly delivered and often recommended following the failure of medication. The paucity of evidence for their effectiveness in these situations is a significant problem. There is a need for studies with a strong controlled design investigating the effectiveness of psychological treatments for patients with treatment-resistant depression.
