This study compared the use of an interactive voice response (IVR) system with a written survey to collect data. Consecutive patients seen in an orthopedic clinic completed the Short Musculoskeletal Function Assessment (SMFA) by either IVR or written questionnaire and then were asked to complete the form again 3-7 days later using the opposite modality. Patient response rates were analyzed for differences between the self-administered IVR and written modes of administration. Three orthopedic clinics participated in the study. No significant differences between method of administration or individual differences in response per patient were found. Therefore, no significant differences in measurement are found when IVR is compared to the written SMFA.
