The study utilized quasi-experimental design with pretest - posttest model has two experimental groups. The population included all of the girl students educating for B.S and M.S graduation degree at the university of science and technology of Iran in 2014-2015. Initial sampling by the recall of implementing the study was conducted voluntary and all the voluntaries completed Padua inventory and among them 12 people who suffered from obsessive-compulsive disorder and verified by clinical psychologist ( base on DSM5) were selected by random sampling and randomly divided into two groups of cognitive-behavioral (n=6) and metacognitive (n=6) groups. Then cognitive-behavioral and metacognitive interventions applied. Each of interventions performed in 10 sessions (2 hours per sessions). In order to analyze mixed multi factorial ANOVA and repeated measure one way ANOVA methods has been used. Both metacognitive therapy and cognitive-behavioral therapy were effective in reducing symptom of obsessive-compulsive disorder, at the end of treatment and after a one-month follow-up. Also, there was no significant difference between the effectiveness of cognitive-behavioral and metacognitive approaches on obsessive-compulsive disorder, at the end of treatment and after one month follow-up. So metacognitive therapy as new therapeutic areas to the extent of psychology, is effective as much as cognitive-behavioral therapy in reducing symptoms of obsessive-compulsive disorder and it’s subscales, and can be used as an alternative treatment.
