Obsessive-compulsive is one of the most common disorders that often has a negative impact on psychological, social and occupational function with a chronic course. New research has shown the role of metacognitive structures in this disorder. The aim of this study was to predict the symptoms of Obsessive-compulsive with metacognition and delusional beliefs. For this purpose, during a descriptive correlational study, 202 students of Karaj Azad University were selected by convenience sampling method and were evaluated for obsessive-compulsive disorder, metacognition and delusional beliefs. Multivariate regression analysis showed that delusional beliefs and metacognitive beliefs can predict obsessive-compulsive symptoms separately. Dysfunctional metacognitive beliefs, such as negative cognitive beliefs about thoughts, negative metacognitive beliefs about oneself, or low cognitive efficiency, also activate threatening judgments about one's performance, these beliefs can disrupt a person's cognitive and behavioral functioning by creating a disturbing negative mental assessment, so that this assessment can intensify negative emotions, such as fear, which eventually manifests as anxiety. The findings of this study support the predictability of obsession through delusional beliefs.
