Psychometric properties of the Pressure Ulcer Knowledge Test (PZ-PUKT) among nurses

Introduction: Pressure ulcers pose a significant challenge to the healthcare system. Nurses can contribute to reducing the frequency of pressure ulcers if they possess up-to-date knowledge in this area. The use of a reliable research tool to assess nurses' knowledge of pressure ulcer prevention and treatment provides opportunities to identify knowledge deficits in this area, leading to the implementation of evaluative actions. Aim of the research: Evaluation of the psychometric properties of the Pressure Ulcer Knowledge Test (PZ-PUKT) in a group of nurses. Material and methods: The study included 82 nurses practicing in primary healthcare settings during postgraduate training sessions. The PZ-PUKT, developed by Pieper and Zulkowski in the 2021 version, was utilised. The test was translated into Polish by 2 independent translators and subsequently evaluated for content validity based on Polish and international guidelines (the Polish Wound Management Society (PTLR) and the National Pressure Injury Advisory Panel (NPIAP)). Results: The level of knowledge among the participants was assessed as above average, with the accuracy of responses in the test exceeding 60%. The psychometric properties of the PZ-PUKT test were determined, and an analysis of item and internal Conclusions: The PZ-PUKT questionnaire meets the basic norms regarding the consistency and quality of question construction. It is recommended that the PZ-PUKT questionnaire be used for assessing the knowledge of nursing students and practicing nurses.
