Development and Validation of Questionnaire Measuring Registered Nurses’ Competencies, Beliefs, Facilitators, Barriers, and Implementation of Evidence-Based Practice

Abstract

Background: Consideration needs to be given to a variety of factors that influence the implementation of evidence-based nursing practice (EBNP). Aim: This study aimed to develop and validate a questionnaire that measures registered nurses’ competencies, beliefs, facilitators, barriers, and implementation of EBNP. Methods: Methodological cross-sectional study in which 612 registered nurses were selected by convenient sampling. A panel of six experts evaluated the content validity of the first draft of the EBP-CBFRI questionnaire. The final questionnaire was made up of 55 items. Reliability was determined by means of internal consistency. Construct, convergent, discriminant, and predictive validity was assessed. Results: The questionnaire has proven acceptable reliability and validity when used with registered nurses. The scale-level content validity index was.92. Cronbach’s α coefficient for the total questionnaire was.87. Exploratory factor analysis supported five significant factors that explained 64.8% of the variance.
