One assumption often made in interpreting study results is that the study variables were adequately measured. This adequacy is determined by examining the fit of operational definitions with the framework and through validity and reliability information. Although reliability and validity of measurement strategies are reviewed before use, one must reexamine the measures at this point to determine the strength of evidence available from the results. For example, did the measurement truly reflect the concept in the study population? Were the validity and reliability of instruments examined in the present study? The validity and reliability of measurement methods are critical to the validity of results.
