Validity and reliability of nursing workload measurement systems: strategies for nursing administrators.

Abstract

In Part One, an overview of the theory related to validity and reliability of workload measurement systems (WMSs) was reviewed. In this article, the MEDICUS WMS is used to provide a concrete example of the type of comprehensive validity and reliability programs that can be established, in an inpatient setting, on the basis of this theory. Practical strategies for monitoring validity and reliability are identified. Administrators can adapt the approaches specified to fit the methodology underpinning other WMSs.
