Traditional Chinese‐version reliability test of the Pieper‐Zulkowski pressure ulcer knowledge: Psychometric and assessment

Abstract

AbstractThis study was to translate the Pieper–Zulkowski pressure ulcer knowledge test (PZ‐PUKT) into Traditional Chinese and evaluate its psychometric properties as well as identify the predictors of knowledge on pressure injury. The PZ‐PUKT was translated into Traditional Chinese (TC‐PZ‐PUKT), and its content validity was evaluated. A total of 296 nurses participated in this study and completed the 72‐item TC‐PZ‐PUKT online. The reliability of the TC‐PZ‐PUKT was analysed by evaluating its internal consistency and test–retest reliability. Hierarchical regression was used to determine factors associated with TC‐PZ‐PUKT scores. Content validity was achieved with a score of 0.986. Internal consistency was observed to be reliable, with a Cronbach's alpha of 0.858. The mean knowledge score on the TC‐PZ‐PUKT was 72.5%, with a 1‐week test–retest reliability of r = 0.849. Education level, certification as a wound specialist and self‐learning through reading articles, books or guidelines on pressure injury were significantly associated with TC‐PZ‐PUKT scores. The TC‐PZ‐PUKT is a valid and reliable tool. Education level, certification as a wound specialist and self‐learning regarding pressure injury are related to knowledge of pressure injury.
