Validation of the Persian Version of " Responsibility Beliefs Questionnaire" in Iranian Adolescents

Studies have indicated the high prevalence of Obsessive-Compulsive disorder in childhood period. Inflated responsibility beliefs are hypothesized to become a central feature of Obsessive-Compulsive disorder (OCD). Given the prevalence of this disorder among children and adolescents as well as further investigation in this field, the present study aimed to investigate the psychometric properties of a Persian version of Responsibility Beliefs scale. In this psychometric study, the Persian version of "Responsibility Beliefs Questionnaire" was completed by 547 15 to 18-year-old students in Shiraz city. Subjects were selected by multistage random cluster sampling; data were analyzed using confirmatory factor analysis. In this study four-factor structure found in original scale, was confirmed by confirmatory factor analysis representing heightened responsibility, Actions Caused/Actions Influenced, Rigid Rules and Overprotection Scales forming responsibility construct in second-order confirmatory factor analysis. In addition, results revealed satisfactory Composite Reliability Index (ranging from 0.60 to 0.85) These results support the reliability and validity of the Persian version of Responsibility Beliefs scale in Iranian adolescents and suggest that this scale may be useful for studying the etiology of inflated responsibility beliefs that are hypothesized to become central in order to development of OCD. However, future research is needed to confirm these data in OCD patients.
