The Persian version of JC questionnaire was prepared by the standard method, forward-backward translation. In order to evaluate the content validity, the questionnaire was sent to 28 ergonomists and the content validity index (CVI) and content validity ratio (CVR) were calculated. The reliability of questionnaire was determined when 221 questionnaires were fulfilled by hospital nurseries. Results: After initial evaluations by experts partial revisions in some subscales were made to approve the CVR. By revisions, the validity of all subscales and consequently the JCQ were confirmed. The Cronbach's alpha coefficient for JCQ dimensions was ranged from 0.65 to 0.89. The total coefficient for the JCQ showed that the questionnaire has high internal consistency in all dimensions measured (? = 0.894). Conclusion: This study showed that the validity and reliability of the Persian version of JCQ are acceptable and it is applicable for assessment of just culture in Iranian organizations and workplaces.
