Development and psychometric property testing of a Medical Device‐related Pressure Injuries Knowledge and Practice Assessment Tool

Abstract

AbstractAimsWe aimed to develop and test the psychometric properties of a Medical Device‐related Pressure Injuries Knowledge and Practice Assessment Tool.BackgroundAssessment of nurses' knowledge and practices is critical in the prevention of Medical Device‐related Pressure Injuries.DesignThis was an instrument development and testing study.MethodsThe sample of the study consisted of nurses (n = 189). The study was conducted in three phases between January and February 2021. In the first phase, multiple‐choice items contained within Aetiology/Risk Factors, Prevention Interventions, and Staging domains were created. In the second phase, content validity and criterion validity were evaluated, and the tool was pre‐tested. The third phase examined item difficulty, discrimination index and distractor quality. The test–retest method was used for reliability.ResultsThe Content Validity Index was found to be 0.75, 0.86 and 0.96 for the domains of Aetiology/Risk Factors, Prevention and Staging, respectively. The item difficulty values of the items were between 0.18 and 0.96. A positive, strong and significant relationship was found between the results and a positive, moderate and significant relationship between the tools administered for the proof of scale validity. The Cronbach's alpha reliability coefficient was found to be 0.54.ConclusionsThe tool is a suitable measurement instrument for use in nursing education, research and clinical settings.
