RESUMO

Cognitive Behavioral Therapy (CBT) is the first-line treatment for a wide number of psychiatry disorders and it is, nowadays, the psychotherapeutic approach with the largest number of controlled trials for the treatment of bipolar disorder. Its use in group format for bipolar disorder has already been tested in open trials, demonstrating good feasibility. Such format has not yet been applied in a controlled trial. This is a two-phase study. For the initial phase, we selected bipolar I and II patients, with scores equal or lower to 8 in the Hamilton Depression Rating Scale 17 items, and equal or lower to 6 in the Young Mania Rating Scale. They were then randomly selected for receiving pharmacological treatment alone (N = 27), or added to 18 sessions of group CBT (N = 23). The sessions were based on an experimental manual developed for this study and lasted 90 minutes each, for a total of six months. The second phase, initiated after the treatment was completed, all patients were evaluated by telephone interview, repeated every three months. The outcome measures were the interval until the first new episode and the presence of new episodes following the treatment, according to the criteria defined by the Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition (DSM IV). Eighty one patients were included in this study, of which fifty have completed the intervention phase and a twelve-month follow-up. Their results are presented in this study. Intention-to-treat analysis showed that there was no difference between groups in terms of time until the first relapse (Wilcoxon = 0.667; p= 0.414). When considering the polarity of the first relapse, this result remained the same for both depressive (Wilcoxon = 3.328; p=0.068), and mania (Wilcoxon =1.498; p=0.221) episodes. The presence of episodes was not statistically different between groups (2 = 0.28, p= 0.6) either. In this pioneer study, we could not demonstrate a significant improvement in the prophylaxis of new mood episodes when adding group CBT sessions to the treatment commonly offered to people with bipolar disorder
