Evaluation of Studies on the Measurement Properties of Self-Reported Instruments

Abstract

S U M M A R Y: Purpose: The purpose of this study was to evaluate studies on the measurement properties of self-reported instruments. Method: This descriptive review included studies on measurement properties that were reported in Asian Nursing Research over a five-year period from 2016 to September 2020. Nine key measurement properties were reviewed for each study: content validity, structural validity, internal consistency, cross-cultural validity/measurement invariance, reliability, measurement error, criterion validity, hypotheses-testing construct validity, and responsiveness. Results: The most commonly applied measurement properties were structural validity and internal consistency. However, structural validity using confirmatory factor analysis or item response theory/Rasch analysis needs to be rigorously analyzed and interpreted. None of the studies assessed measurement error and responsiveness. Conclusion: It is recommended for nursing researchers to assess measurement properties beyond structural validity and internal consistency using more rigorous methodologies.
