The Persian Version of the Personality Beliefs Questionnaire-Short-Form (PBQ-SF): A Psychometric Evaluation

This study designed to examine the factor structure, internal consistency, and convergent validity of the Persian PBQ-SF in a sample of 502 university students in Iran (M age = 23.22,SD = 4.99, 56.6% women). Confirmatory factor analysis supported the proposed ten-factor model. The internal consistency of the Persian version of PBQ-SF ranged from .56 (Avoidant) to .81 (Histrionic), while MIC values indicated reliabilities in the acceptable range for all PBQ-SF factors. Also, ex pected associations between PBQ-SF factors (e.g., Narcissism and Antisocial) and external correlates (e.g., Disinhibition and Antagonism) supported the measure's convergent validity. The findings indicated that the Persian version of the PBQ-SF has sound psychometric properties and is a valid and re liable tool for assessing dysfunctional beliefs.
