Cognitive therapy for bipolar depression: a pilot study.

OBJECTIVE: While the efficacy of cognitive-behaviour therapy (CBT) for the treatment of acute unipolar major depression is well-documented, there is almost no data evaluating its utility in the treatment of bipolar depression. This pilot study compares the efficacy of CBT combined with mood-stabilizer pharmacotherapy for bipolar depression and CBT alone for unipolar depression. METHOD: A matched-case control design was used to evaluate outcomes following 20 sessions of CBT in 11 depressed bipolar patients and 11 matched recurrent unipolar depressed control subjects. RESULTS: Bipolar depressed patients achieved similar levels of reduction in depressive symptoms following CBT, as did the unipolar depressed group. However, on measures of more pervasive dysfunctional attitudes, bipolar patients did not improve to the same degree. CONCLUSIONS: Preliminary findings suggest that CBT warrants further investigation as an effective psychosocial intervention for depression in bipolar patients already receiving ongoing mood-stabilizing pharmacotherapy.

Are dependency and self-criticism risk factors for major depressive disorder?

OBJECTIVE: To determine whether dependent and self-critical personality traits are associated with specific types of life events and whether these traits change with pharmacotherapy. METHOD: Overall, 142 depressed outpatients completing 8 weeks of fluoxetine treatment were administered the Life Experiences Survey (LES) at baseline and the Dysfunctional Attitude Scale (DAS) and Hamilton Depression Rating Scale (HDRS) at baseline and endpoint. RESULTS: The DAS dependency subscale, but not the self-criticism subscale, showed significant correlations with life events regardless of congruency. Baseline HDRS scores were positively correlated with both DAS subscales and total score. The DAS subscales, the total DAS score, and the HDRS all improved significantly with treatment. CONCLUSIONS: These results confirm a growing body of research that has found an association between sociotropic or dependent personality traits and life events.
