Introduction: Hospital malnutrition is a widespread health problem. Most studies on hospital malnutrition used different validated screening tools to determine malnutrition and the nutritional status of patients. Therefore, it is not possible to compare the prevalence of malnutrition among wards and hospitals. The nutritionDay project is a one-day, cross-sectional audit run in healthcare institutions. The nutritionDay hospital questionnaires are available in more than 30 languages and it includes 4 sheets focused on hospital structure, ward structure/processes, patient’s clinical condition, patient’s nutritional status, and 30-day outcome. For the first time, we analyzed to prove the validity and reliability of the Persian translation of the nutritionDay questionnaires.Method: At first, two separate people did the questionnaire's translation into Persian and re-translation into English. Then, the translation was sent to 15 experts to assess content validity. The validity of the questionnaire was evaluated by checking relevance, clarity, simplicity, and importance score. Questions with a content validity ratio (CVR)>0.49 were accepted. The average technique was used to calculate the content validity index (CVI). Also, Cronbach’s alpha coefficient and test-retest couldn’t be calculated for reliability assessment due to the variety of variables and the nature of the nutrition questionnaire.Result : Overall, the CVR of all questions was above 0.49. Also, the CVI-Relevancy, CVI-Clarity, CVI-simplicity, and Importance scores of the final tool were 0.98, 0.99, 0.99, and 4.69 respectively.Conclusion : This Persian translated nutritionDay questionnaire demonstrates strong content and face validity. Furthermore, it can be an appropriate tool for evaluating patients' clinical conditions and nutritional status.
