... ionnaire to collect information. Exploratory factor analysis was run using SPSS 21. Then, construct validity was evaluated using confirmatory factor analysis (CFA), convergent validity, and discriminant validity by AMOS 21. Results: Exploratory factor analysis extracted four dimensions that explained 65.5% of the variance observed. The results of confirmatory factor analysis showed that our data fitted the hypothesized four dimensional model of work-family conflict construct. The average variance extracted was used to establish convergent and discriminant validity. Conclusion: The Persian version of work-family conflict questionnaire is a valid and reliable instrument among Iranian nurses.
