Psychometric Properties and Factor Structure of the Behavior Problems Inventory in Iranian Elementary Students with Intellectual Disability

Objective: This study aimed to evaluate the psychometric properties and the factor structure of the Behavior Problems Inventory (BPI-۰۱) among students with intellectual disabilities in Iran. Methods: The Persian version of BPI-۰۱ was administered to the care staff of Iranian children and adolescents (n=۵۹۱) who had been detected as suffering from intellectual disabilities. Iranian children and adolescents with intellectual disabilities in the present study lived in one of the ۴ provinces of Tehran, Esfahan, Karaj, and Kurdistan. Cronbach α and confirmatory factor analysis (CFA) were used for analyzing the data.  Results: The results of the study showed that the scale could reach an acceptable level of internal consistency (Cronbach α ranged from ۰.۸۳ to ۰.۹۴). Furthermore, CFA supported the unidimensionality of the subscales as well as ۳ factor structure proposed in the original BPI-۰۱. Conclusion: The Persian version of BPI-۰۱ enjoys an acceptable level of reliability and is explained by the same factor structure proposed in the original BPI-۰۱. The limitations and some applications of the present study will be discussed too.
