Validity and Reliability Testing of an Instrument Measuring Nurses' Experiences With Electronic Medical Record-Related Unintended Adverse Consequences and Statistical Interpretations of Exploratory Factor Analysis Outputs.

Abstract

Background and Purpose: Nurses frequently experience unintended consequences of health information technology implementation. The study aimed to test the validity and reliability of a new instrument to measure nurses' experiences with the unintended adverse consequences of electronic medical record use. Methods: The psychometric properties of the developed 21 items were examined using a convenience purposive sample of 287 nurses from eight hospitals. Results: The content validity index was 1.00. The sample was adequate to proceed with exploratory factor analysis. Four factors were clustered with factor loadings between 0.43 and 0.82. The variance explanatory proportion was 63.1%. Cronbach's alpha was .93. Conclusions: The psychometric testing results indicated that the instrument was valid and reliable. The instrument can serve as an indicator of unintended consequences of health information technology implementation.
