Objective: This research aimed to study the relationship between scrupulosity and obsessivecompulsive symptoms as well as obsessive-compulsive-related cognitive styles (obsessive beliefs and thought-action fusion).  Methods: This was a correlational study. The study population included all individuals who referred to counseling centers of Tehran from August to December ۲۰۱۰ and diagnosed with obsessive-compulsive disorder, and also all Persian speakers with OCD who were active in internet from August to November ۲۰۱۲. A total of ۳۰ individuals with obsessive-compulsive disorder (mostly Iranian Muslims) were recruited from different psychological counseling centers in Tehran. In addition, ۵۰ individuals with OCD (obsessive-compulsive disorder) were recruited via internet social networks. For screening, we used Obsessive-Compulsive Inventory-Revised (OCI-R). Convenience method was used for the sampling. In order to collect data, Penn Inventory of Scrupulosity (PIOS), Thought-Action Fusion Scale (TAF), Depression Anxiety Stress Scale (DASS-۲۱), Obsessive-Compulsive Inventory-Revised (OCI-R), and Obsessive Beliefs Questionnaire (OBQ) were administered. Pearson correlation coefficient and regression analysis were used to analyze the data. SPSS version ۱۸ was used for data analysis.  Results: Results showed that there were significant relationships between scrupulosity and obsessive-compulsive symptoms total score (r=۰.۲۷۵, P<۰.۰۵) also scrupulosity and obsessive beliefs (r=۰.۵۵۸, P<۰.۰۱) and scrupulosity and thought-action fusion (r=۰.۵۰۶, P<۰.۰۱). Results also revealed that the variations in scrupulosity scores could be best predicted by ‘anxiety’ and ‘Importance and Control of Thoughts.’ Scrupulosity is a subtype of OCD and is obsessive in nature.  Conclusion: As explained by cognitive-behavioral theories of religious OCD, scrupulosity is closely related to the ‘Importance of Thoughts and Controlling Thoughts,’ as well as moral and probability ‘Thought-action Fusion.’ The results were in accordance with the findings of comparable studies on Christian samples. Results were explained according to Islamic views, and the implications for research and practice were discussed.
