- Abstract
- Patient-reported data, specifically patient-reported outcomes (PRO) measurement, has grown in relevance to patient-centeredness in healthcare delivery as well as in clinical outcomes research. Nonetheless, the uptake of PRO measurement tools, although many have been validated and approved for use in research settings, has been slow on the part of clinical outcomes researchers due to their preference for more objective, performance-based outcomes measurement. Consequently, there is a need for confirming the value of PROs in patient-centered research and assessing the role dynamic of PROs versus performance-based tests in outcomes research. In an effort to fill investigators’ knowledge gap in this area, the following secondary data analysis, conducted upon baseline and follow-up data from the 2011 Walk With Ease program (a community walking program for arthritis patients), evaluated the validity and value of PRO measures as compared to performance-based measures of physical functioning. Primary results found that patient-reported and performance-based measures were poorly correlated with one another, indicating that they measure physical function differently from one another. Furthermore, both measures detected significant changes in physical functioning over time, indicating that they may be equivalently effective in assessing an intervention centered on improving physical functioning. Finally, the patient-reported measures were more strongly inversely correlated with other key arthritis symptoms than performance-based measures, meaning they may have been more effective in measuring physical function in the context of arthritis. There findings will ideally provide an impetus for researchers to recognize the validity and value-added of patient-reported data and incorporate it more widely into outcomes research.
