    Abstract: The aim of this study was to investigate the efficacy of Meta-Cognitive Therapy (MCT) in improving
meta-cognitive beliefs and thought control in treating patients with Obsessive-Compulsive Disorder (OCD).
This semi-experimental study was conducted with pretest-posttest and follow-up design, using control group.
Total 28 patients were selected through objective sampling method and randomly divided into two equal
experimental and control groups. Experimental group experienced 8 weeks of Well’s meta-cognitive therapy
while control group were just followed-up. Meta-cognition Questionnaire-Short Form (MCQ-30) and thought
control questionnaire was used in pretest, posttest and 1 month follow-up as the study instrument. Data
analyzed by descriptive indices and multivariate analysis of covariance using SPSS Software. The experimental
group showed significant decrease in meta-cognitive beliefs and thought control general scores in post-test
and follow-up, compared with control group. Well’s meta-cognitive model proved to be beneficial in improving
meta-cognitive beliefs and thought control in OCD patients. Current approach enables a deeper treatment of
clinical functionality and we have to do to get a new set of strategies that can help patients to make a new
relationship with the thoughts. Thus, the approach should be considered in future treatments of
obsessive-compulsive patients.
