Codes and Frequencies
For sample adults who had seen a practitioner for folk medicine in 2002 (FOKYR) or had seen a traditional healer in 2007 (FOKBOTANYR, FOKCURANYR, FOKESPIRYR, FOKNAMYR, FOKSHAMYR, FOKSOBAD, or FOKYERBYR) during the past 12 months, FOKNO reports how many times the respondent had seen such a practitioner or healer during the past year.
Response categories for FOKNO report the number of visits to a practitioner in grouped intervals, ranging from "Only one time" to either "More than 10 times" (2002) or "More than 20 times" (2007). Those who had seen a practitioner for folk medicine were also asked in 2002 whether any of the costs of using folk medicine were covered by insurance (FOKINSURE), and were asked in 2007 what the average out-of-pocket expense for each visit to such a practitioner had been (FOKPAID).
Variables similar to FOKNO, which report the number of visits to a practitioner of alternative medicine, are available for the following alternative health modalities:
- Acupuncture (ACUNO)
- Ayurveda (AYUNO)
- Biofeedback (BIONO)
- Chelation (CHENO)
- Chiropractic or osteopathic manipulation (COMNO)
- Special diets (DITPRACNO)
- Energy healing therapy (EHTNO)
- Homeopathic treatment (HOMPRACNO)
- Hypnosis (HYPNO)
- Massage (MASNO)
- Movement techniques (MOVNO)
- Naturopathy (NATNO)
- Relaxation techniques (RELCLASSNO)
- Yoga, Tai chi, or Qi gong (YTQCLASSNO)
- Herbal medicines (HERPRACNO)
For more information on the full range of variables related to folk medicine, including definitions, see FOKYR.
The question wording for FOKNO differs between 2002 and 2007.
In 2002, respondents were asked, "During the past 12 months, how many times did you see a practitioner for folk medicine?"
In 2007, respondents were asked, "During the past 12 months, how many times did you see [fill: type of traditional healer]?"
In addition to these changes in question wording, the response categories also differ between the two years.
There are 4 substantive response categories in 2002, and 6 such categories in 2007. To maximize comparability across years without sacrificing detail, IPUMS NHIS uses composite coding for this variable, with the first digit indicating broad ranges of numbers of visits (1 = "Only one time"; 2 = "2 to 10 times"; 3 = "More than 10 times"). The second digit supplies detail present in only some years, such as distinguishing among "More than 10 times" (IHIS code 30), "11 to 15 times" (IHIS code 31), "16 to 20 times" (IHIS code 32), and "More than 20 times" (IHIS code 33). Researchers who wish to maximize comparability between 2002 and 2007 can combine categories beginning with the number 3 into a single "More than 10 times" category.
