Introduction: Metacognitive Therapy (MCT) focuses on reducing unhelpful cognitive processes and facilitating metacognitive styles of processing. MCT enables patients to interrupt rumination, reduce unhelpful self-monitoring tendencies, and establish more adaptive styles of responding to thought and feeling. In this research it has been tried to study the effectiveness of this kind of intervention on improving major depression patients.
Method: This research in the framework of single case experimental plan was conducted during 6-8 sessions on 3 patients with 1 and 3 months follow-up by using multiple-baselines plan. Instruments used in this research were included BDI II, BAI and RRS.
Results: Treatment created significant and considerable changes in depression, anxiety, and rumination symptoms of all three depressed patients.
Conclusion: Results of this study show that meta-cognitive therapy which instead of cognition content, focuses on controlling processes prominent on it, can be effective in treatment of patient with major depression. In present study, this kind of treatment created significant changes in symptoms of all 3 patients and therapeutic achievements were maintained over follow-up.
