Description
BIOSURG reports if the person has ever received surgery for most important health condition she/he treated with biofeedback. Please see the Comparability and Universe tabs for more information on changes in this variable over time.
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, in universe persons were 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. Persons who did not include biofeedback among their top three CAM therapies did not answer follow-up questions for this therapy and are reported as responding no.
Changes in universe also pose comparability challenges; in 2007, only sample adults were included in the universe. Beginning in 2012, however, sample adults and sample children are included in the universe.
Universe
- 2007: Sample adults age 18+ who have seen a practitioner for biofeedback during the past 12 months and have used biofeedback for a specific health problem or condition.
- 2012: Sample adults age 18+ and sample children ages 4-17 who have reported having at least one top CAM therapy and using this therapy to treat a specific health problem or condition.
