The Psychometric Analysis of the Certified Registered Nurse Anesthetist Workload Perception Scale (CWPS): Final Phase.

BACKGROUND AND PURPOSE In two previous studies, the Certified Registered Nurse Anesthetist (CRNA) Workload Perception Scale (CWPS) was developed. The purpose of this paper is to report the final psychometric validation of the CWPS. METHODS An 11-item CWPS was tested in a population of CRNAs. Classical psychometrics were performed on the 11-item instrument piloted in a sample of 393 CRNAs. RESULTS Parametric and nonparametric analysis indicated 7 of 11 items were a good fit to measure perception of workload. CONCLUSIONS A revised 7-item final CWPS was developed.
