Abstract

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.

Keywords: CRNA; instrument development; psychometric; workload.
