Providing a structural model for predicting symptoms of practical obsessive compulsive disorder based on religious adherence the mediating role of personality function

Obsessive-compulsive disorder is a clinical syndrome, characterized by disturbing and intrusive thoughts, images, or impulses and repetitive behaviors.

This study aimed to present a structural model for predicting the symptoms of obsessive-compulsive disorder based on religious adherence and commitment and to evaluate the mediating role of personality function.

This study was a descriptive correlational performed based on structural equation. The statistical population consisted of people referred to clinics in districts 1, 2, 7, 8, 11, and 12 of Tehran, Iran, during 2020-2021. A total of 378 volunteers were considered eligible for the study based on the inclusion criteria. The data collection tools included Hodgson and Rachman’s Obsessive- Compulsive Disorder Questionnaire (1977), Janbozorgi’s Religious Faith Questionnaire (2009) and Personality Function Questionnaire by Janbozorgi & et al (2021). Data analysis was performed in SPSS-28 and LISREL-8.5, using path analysis in AMOS-24, as well as structural equation modeling.

The Square of correlations (R2) for obsessive-compulsive disorder was 0.53; therefore, the domains of religious adherence and personality function could explain 53% of variance in obsessive-compulsive disorder.

Personality function mediated the relationship between lack of religious adherence or religious ambivalence and obsessive-compulsive disorder positively and mediated the relationship between religious adherence and obsessive-compulsive disorder in a significant and negative way. It is recommended that counseling centers pay attention to the clients' religious adherence and dysfunctional religious beliefs in the treatment of obsessive-compulsive disorder.
