Abstract

Instruments that are valuable in clinical research yield similar results when used by different users, in different settings, and at different times. Reliability studies test the reproducibility of instruments by examining the relationship between the predicted distribution of measurements, the actual measurement distribution, and the resulting measurement error. Understanding the study types and common statistical measures is imperative when conducting or appraising reliability studies. Surveys are useful tools in orthopedic research for obtaining information on the views and practices of large populations in an efficient and cost-friendly manner. An intentional and organized approach to survey design and administration can assist to maximize response rate, thus decreasing noncompliance, bias, and increasing generalizability of the results.
