Abstract

Background: There are different tools for assessing evidence-based practice in nursing in Iran, however, there are some limitations in each of them, and they do not examine EBP comprehensively. Objectives: The purpose of this study was to evaluate the validity and reliability of the Persian version of EBPQ. Methods: This study was a methodological research on 300 nurses working in Guilan province (Iran). A cluster sampling was done. After a forward-backward translation, the questionnaire was translated into Persian and its psychometric evaluation was done. Results: CVIs for all items were >= 0.8 and CVRs were >= 0.63. All of the impact scores were > 1.5. Cronbach's alpha of the scale was 0.92. The ICC test was 0.96 and significant (P < 0.001). In exploratory factor analysis, KMO was 0.84 and Bartlett's test was significant (P < 0.001). Confirmatory factor analysis showed an acceptable fit model. Conclusions: This study introduces the evidence-based practice questionnaire (EBPQ) as a valid and reliable tool to assess the status of evidence-based practice among nurses in Iran.
