Background and Purpose: In a previous study, the CRNA Workload Perception Scale (CWPS) was developed. The purpose of this study was to investigate the psychometrics of the CWPS. Methods: The CWPS was tested in a population of CRNAs. This study was conducted in two phases. Phase I consisted of classical psychometrics; the 12-item instrument was piloted in a sample of 265 CRNAs. Phase II consisted of qualitative analysis to provide feedback on items that did not perform well. Results: Phase I: Instrument demonstrated good reliability (r =.77). Parametric and nonparametric analysis indicated 6 of 12 items were good fit to measure perception of workload. Phase II: Qualitative analysis resulted in refinement of four items, addition of one item, and elimination of two items. Conclusions: A revised 11-item CWPS was developed.
