Psychometric properties of Nurses Professional Values Scale-Revised: An Iranian version

Professional values are the basis of development of professional identity and commitment. Evaluation of professional values provides critical information regarding effective strategies for their integration in professional performance and clinical learning. The present study aimed to determine the psychometric properties of Nurses Professional Values Scale-Revised (NPVS-R) in Iranian population. This methodological study was conducted on ۴۳۹ students in the last semester of nursing selected from Iran’s universities using stratified single-stage cluster sampling. After back translation, its face, content, and construct validity were assessed. Its reliability was also evaluated by determining Cronbach’s alpha using internal consistency method. All analyses were performed using the SPSS statistical software, version ۱۹. Considering face validity, all items’ impact scores were above ۱.۵. Regarding content validity, CVR and CVI of all components were > ۰.۶ and = ۱, respectively. After exploratory factor analysis, the number of items was reduced to ۲۵ and five factors explained ۵۲.۲۶% of the total variance. Moreover, the reliability coefficient was ۰.۵۳-۰.۸۳ for the factors and ۰.۹۱ for the whole scale. The Persian version of NPVS-R had acceptable validity and reliability in Iranian context. Yet, further studies have to be conducted on this instrument with different cultural backgrounds.
