Comparison of the efficacy of cognitive-behavioral therapy and acceptance and commitment based therapy on aggression and mania symptoms in bipolar disorder patients.

The purpose of this study was to compare the efficacy of cognitive-behavioral therapy and admission-and-acceptance therapy treatment on aggression and mania of bipolar disorder patients. In this quasi-experimental study, using convenience sampling method, pre-test and post-test with control group, 36 patients referred to psychiatric hospitals, who according to DSM5 criteria, diagnose bipolar disorder. They were randomly divided into three groups of 12 each. The first group received 10 sessions of CBT, the second group received 12 sessions of ACT and the control group received no intervention. Data were collected through Buss and Perry's (1992) and Mania Young's (1987) Aggression Questionnaires. Covariance analysis was used for data analysis. The results showed that CBT and ACT treatment in the experimental groups decreased the components of physical aggression and anger, but there was no significant difference between the verbal aggression and hostility components. There was a significant difference between the experimental and control groups (P <0.05), except for the anger component, there was no difference between of the two treatments.
