Measuring self-efficacy and outcome expectancy in evidence-based practice: A systematic review on psychometric properties

Background: Evidence-based practice has developed over the last 30 years as a tool for the best possible nursing care. Nevertheless, many nurses do not regularly participate in the evidencebased practice process. Barriers to participation include nurses’ self-perceived ability in successfully fulfilling evidence-based practice-related tasks (self-efficacy) and their expectations of the positive outcomes of such tasks (outcome expectancy).

A comprehensive overview of the psychometric properties of such instruments is lacking
