Psychometric Validation of the Perceived Perioperative Competence Scale-Revised in the Swedish Context

Abstract

Purpose: To psychometrically test the Perceived Perioperative Competence Scale-Revised (PPCS-R) in the Swedish context. Design: Cross-sectional survey. Methods: The 40-item PPCS-R was translated into Swedish using a forward-translation approach. A census of 2,902 registered nurse anesthetists (RNAs) and operating room (OR) nurses was drawn from a database of a national association in Sweden. Finding: The response rate was 39% (n 5 1,033; 528 RNAs and 505 OR nurses). Cronbach alpha for each factor was 0.78 to 0.89 among OR nurses and 0.79 to 0.88 among RNAs. Confirmatory factor analysis showed good model fit in the six-factor model. Conclusions: Psychometric testing of the Swedish translation of the PPCS-R suggests a good construct validity, and the construct and its six factors are conceptually relevant among the Swedish OR nurses and RNAs.
