Background Parenting style is associated with children's health-related behaviors. One of the popularity and applicability assessment tools is Parenting Style and Dimensions Questionnaire (PSDQ) that the lack of Persian version can be seen. This study was conducted to determine the validity and reliability of Persian version of PSDQ. Materials and Methods This study was done with randomized cluster sampling on 588 parents. Cronbach's alpha (alpha) coefficient was used to determine the internal consistency and Pearson`s correlation coefficients was used to for test-retest reliability and the construct validity. Conformity factor analysis was also, applied to determine the construct validity. Results: Cronbach's a coefficient for two authoritative and authoritarian styles with the highest estimated value were 0.86 and it was 0.41 for permissive style. The results of the correlation test in all three afore mentioned styles were significant. Correlation coefficients between authoritative style and its subscales were about from 0.86 to 0.89 and between authoritarian style and its subscales were about from 0.81 to 0.87. Confirmatory factor analysis showed that goodness-of-fit indices, including CMIN/DF, GFI, CFI, IFI and RMSEA, were 2.1, 0.91, 0.90, 0.90, and 0.04, respectively, which indicated a good the construct validity of instrument. Conclusion: The PSDQ that has been translated into Persian obtained good reliability and validity. PSDQ questionnaire can be considered a useful tool in the assessments and interventions concerning parenting styles used in Iran.
