Aim: The present study aimed to examine the psychometric properties of the Persian version of the Obsessive Beliefs Questionnaire–20 item version (OBQ-20).
Method: The statistical population consisted of women residing in Tehran. A total of 843 participants were selected through convenience sampling. The data collection instruments included the Obsessive Beliefs Questionnaire (OBQ-20; Moulding, 2011), the Maudsley Obsessional Compulsive Inventory (MOCI; Hodgson, 1977), the Self-Ambivalence Measure (SAM; Bhar, 2007), and the Responsibility Attitude Scale (RAS; Salkovskis, 2000). Descriptive statistics and confirmatory factor analysis (CFA) were used to assess construct validity. Pearson correlation coefficients were calculated to evaluate convergent validity, and Cronbach’s alpha and test-retest methods were employed to assess reliability.
Results: The results of CFA supported the four-factor model with acceptable fit indices (RMSEA=0.067, SRMR=0.055, CFI=0.906). Significant correlations between the total and subscale scores of the OBQ-20 and the related scales (MOCI, SAM, and RAS) indicated good convergent validity (r=0.52 to r=0.76, p<0.01). The questionnaire also demonstrated strong reliability, with a Cronbach’s alpha of 0.92 for the total score, 0.75 to 0.84 for the subscales, and a test-retest coefficient of 0.79.
Conclusion: The 20-item version of the Obsessive Beliefs Questionnaire showed satisfactory validity and reliability. Therefore, it can be considered a valid tool for assessing obsessive beliefs in women residing in Tehran.
