With the advent of evidence-based practice, an increased responsibility has been placed on clinicians to understand and apply evidence to patient care. Many clinicians have recognized this responsibility only to find themselves at an impasse when arriving at the results and data analysis section of a journal article. The ability to interpret research requires a process of active learning and a reasonable starting point, as numerous statistical tests, analyses and measurement principles exist. With the evolving paradigm shift toward evidence-based practice, many clinicians have begun to recognize that reproducibility (reliability) and validity are necessary considerations when choosing a test or measurement. With an understanding of reliability and validity, clinicians can recognize the merits and limitations of a particular test and thus have confidence in their interpretation of the clinical examination.


The goal of this continuing education program is to provide an introductory framework for clinicians who want to interpret statistical tests of reliability and validity. After studying the material presented here, you will be able to:
  • Recognize the clinical utility of the more common statistical values of reliability
  • Differentiate change in a measurement that represents true difference from change that represents error
  • Understand the clinical utility, merits and limitations of statistical values of validity
