This ex- post facto study was carried out on 174 individuals (58 depressed, 58 obsessive-compulsive, and 58 normal). The depressed and obsessive-compulsive patients were selected from psychological clinics in central and southern Tehran using purposive sampling. The normal group was randomly selected from the staff of the related clinics. Participants completed three questionnaires includ- ing the Beck Depression Inventory-II (BDI-II), the Maudsley Obsessive-Compulsive Inventory (MOCI), and the Meta-CognitionsQuestionnaire-30 (MCQ-30). The MANOVA test was used to ana- lyze the statistical data. There were significant differences between the mean scores with regard to the meta-cognitive beliefs in normal individuals and in patients with depression or obsessive- compulsive disorders. Furthermore, with regard to cognitive confidence and cognitive self-con- sciousness subscales, there were significant differences between depressed and obsessive-com- pulsive patients. The mean scores of these two subscales were higher in obsessive-compulsive pa- tient, in comparison with depressed individuals. There was no significant difference between the depressed and obsessive-compulsive groups regarding the three subscales of positive beliefs about worry, uncontrollability and need to control thoughts.
