Myoung soo kim, Ph D
Introduction: Pressure ulcers are a major issue in contemporary healthcare, with prevalence and incidence rates of 12.8 and 5.4% respectively based on the 2008-2018 data from a systematic review in 2020. The implementation of pressure ulcers(PUs) prevention is essential for all patients however only two-thirds of Korean nurses are reported to be performing PU prevention tasks, such as risk assessment. Nurse with greater knowledge of PU prevention would be expected to perform it more often than those with less knowledge. The purpose of this study was to evaluate the psychometric properties, including content validity, validity of multiple choice items, and the reliability of the Korean version of the Pressure Ulcer Knowledge Assessment Tool (K-PUKAT 2.0), using classical test theory (CTT) and item response theory (IRT).
Methods: Linguistic validation process and factor analysis were conducted among wound care nurses, staff nurses and nursing students. Items were analysed according to the CTT and IRT using a two-parameter logistic model. Intraclass correlation coefficients were used to examine reliability.
Results: A total of 378 wound care nurses, staff nurses and nursing students participated in this study. While most items showed moderate difficulty based on the CTT, difficulty index values based on the IRT were more broadly distributed (low: 5 items; moderate: 9 items; high: 1 item). The intraclass correlation coefficient for K-PUKAT 2.0 was 0.72.
Discussion: The K-PUKAT 2.0 demonstrated concise and good psychometric properties. Based on the results of this study, repetitive use of K-PUKAT 2.0 will not only help in distinguishing whether an individual has sufficient clinical knowledge, but will also play a key role in supporting learning.
