Development and Testing of the Nurse Manager EBP Competency Scale

Abstract

The purpose of this study was to develop and evaluate the validity and reliability of an instrument to measure nurse manager competencies regarding evidence-based practice (EBP). The Nurse Manager EBP Competency Scale consists of 16 items for respondents to indicate their perceived level of competency on a 0 to 3 Likert-type scale. Content validity was demonstrated through expert panel review and pilot testing. Principal axis factoring and Cronbach’s alpha evaluated construct validity and internal consistency reliability, respectively. Eighty-three nurse managers completed the scale. Exploratory factor analysis resulted in a 16-item scale with two subscales, EBP Knowledge (n = 6 items, α = .90) and EBP Activity (n = 10 items, α = .94). Cronbach’s alpha for the entire scale was .95. The Nurse Manager EBP Competency Scale is a brief measure of nurse manager EBP competency with evidence of validity and reliability. The scale can enhance our understanding in future studies regarding how nurse manager EBP competency affects implementation.
