Abstract

<jats:title>Abstract</jats:title> <jats:p>Background 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. Methods This methodological study was conducted on 439 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 19. Results Considering face validity, all items’ impact scores were above 1.5. Regarding content validity, CVR and CVI of all components were &gt; 0.6 and = 1, respectively. After exploratory factor analysis, the number of items was reduced to 25 and five factors explained 52.26% of the total variance. Moreover, the reliability coefficient was 0.53–0.83 for the factors and 0.91 for the whole scale. Conclusions 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.</jats:p>
