Previous research has shown that vulnerable self-themes and feared self-perceptions may play an important role in the development and maintenance of obsessive-compulsive disorder (OCD). In particular, the recently validated multidimensional version of the fear-of-self questionnaire (FSQ-MV) has shown strong relationships with OCD symptoms independent of cognitive constructs and negative mood in non-clinical samples. The current study aimed to further evaluate the validity and reliability of a Persian version of the FSQ-MV in OCD patients (N = 300), as well as non-clinical individuals (N = 300). Participants completed a set of scales evaluating feared self-perceptions and OCD-related symptoms/conditions. The results showed that the Persian version of the FSQ-MV replicated the three-factor structure of the original scale in non-clinical and OCD patients. The FSQ-MV and its subscales had excellent reliability. Additionally, the FSQ-MV was significantly associated with related cognitive constructs, as well as OCD symptoms and their severity, in both samples. The feared self, especially the corrupted feared self, was a significant unique predictor of OC symptomology, especially for repugnant obsessions, and OCD severity. The study confirmed the validity and reliability of the Persian version of the FSQ-MV. Moreover, cognitive conceptualizations may benefit from a consideration of the feared self in OCD, which may play an important role in its development, maintenance, and severity.
