Accordingly, the present study was designed and implemented to determine the psychometric properties of Persian version of barriers and facilitators assessment instrument of hand washing among nurses in Medical Training Center affiliated with Tehran University of Medical Sciences. The current study is an applied descriptive one with methodological and validation features. The research population includes nurses working in the Health Center affiliated with Tehran University of Medical Sciences (Dr. Shariati Hospital) of whom 184 subjects were selected through simple random sampling based on inclusion criteria. Validity of instrument was assessed through measuring content validity index (Waltz and Basel), face validity and exploratoiy factor analysis. Reliability of questionnaire was evaluated using test-retest and internal consistency of instrument. Exploratoiy factor analysis was conducted using SPSS 21 Software. To determine content validity of instrument, CVI and CVR of items were measured 84 and 58%, respectively. After exploratory factor analysis, number of items was reduced from 25 to 22 and all items were classified in five dimensions including personal and environmental barriers, surveillance and work ethic, physical conditions and receiving benefits, infection control and winning patient’s trust and observing his rights. The total intra-class reliability of instrument was calculated from 68-89% and its average 80%.
