If you want to start a long journey towards patient safety, you should create a good culture of patient safety among employees alongside structural interventions. The first step in doing so is the assessment of current culture in the organization using different tools. One of the most commonly used instruments of measuring patient safety culture is Hospital Survey of Patient Safety culture (HSOPS). The aim of this study was to assess the validity and reliability of Farsi version of this questionnaire for the first time in Iran's hospitals.


We purposefully selected four hospitals out of seven general Tehran University of Medical Sciences affiliated hospitals. Then a 420 sample of staff of these hospitals were taken randomly. Staff was asked to complete the questionnaire. Confirmative factor analysis, correlation coefficient, Cronbach's alpha were employed in statistical analyses.


Factor loadings for almost all questions were acceptable. Factors jointly explained 77.8% of the variance in the responses. The Cronbach's alpha coefficient was between 0.57 and 0.8. The study revealed that over 70% of employees were working at their hospitals more than 40 hours a week and also more than half of the employees were not reporting errors.


Farsi version of HSOPS with 12 dimensions and 42 questions is a valid and reliable questionnaire to measure patient safety culture for the first time in Iran hospitals. This tool will be helpful in tracking improvements and in heightening awareness on patient safety culture in Iran.
