Comparability

Prior to 2012, in universe persons were asked about a series of specific health problems, symptoms, or conditions they may have treated with different complementary and alternative medicine (CAM) therapies. Beginning in 2012, persons were instead asked to select three of sixteen therapies that were most important and only asked the series of questions related to treating health problems, symptoms, or conditions about these top three therapies. Respondents were only asked follow-up questions about the CAM therapies that they included among their top three CAM therapies. Persons who did not include chiropractic or osteopathic manipulation therapy among their top three CAM therapies are recording as responding "no" to COMTVISION. For more information on the construction of this variable, please see TABDOM1. There are no comparability issues.
