Validity and Reliability of the Pieper-Zulkowski Pressure Ulcer Knowledge Test for Use in Turkey

Abstract

OBJECTIVETo assess the validity and reliability of the Pieper-Zulkowski Pressure Ulcer Knowledge Test (PZ-PUKT) for use in Turkey.METHODSThis methodological study was carried out at a state hospital from June to November 2022. The authors used the PZ-PUKT and nurse identification form for data collection. They assessed the validity and reliability of the PZ-PUKT for Turkish society by evaluating language validity, content validity index, exploratory factor analysis, confirmatory factor analysis, Cronbach alpha, Spearman-Brown Split-Half analysis, item-scale correlations, and test-retest correlations.RESULTSItem-level content validity indices ranged from .778 to 1.000 and the scale-level content validity index was .960. Factor loadings of the Turkish version of the PZ-PUKT ranged between .297 and .671. Cronbach alpha coefficients for the scale subsections were .838 for wounds, .851 for prevention, and .844 for staging, the Cronbach alpha coefficient was .936 for the total scale score.CONCLUSIONSThe PZ-PUKT is valid and reliable for use with nurses in Turkey. The authors recommend using the Turkish version of the tool in education and research to assess nurses' pressure injury knowledge.
