The 2002 NHIS recognized 74 conditions (including an "other" category) that respondents could have treated with high dose or megavitamin therapy. (See VITYTREAT for the full list.) To obtain responses to VITYCON1, VITYCON2, and VITYCON3, the interviewer first asked, "For what health problems or conditions did you use high dose or megavitamin therapy?" After recording all answers, the interviewer displayed the list of conditions reported by the respondent and asked, "Which three of these are the most bothersome?"

Respondents were then asked, "How much do you think high dose or megavitamin
therapy helped your (display for each condition)? Would you say a great deal, some, only a little, or not at all?" Responses to this question are reported in VITYCON1HELP, VITYCON2HELP, and VITYCON3HELP.

Variables similar to VITYCON2HELP, which report the degree of help provided by other modalities of alternative medicine for the second of the three most bothersome conditions, include:

• Acupuncture (ACUCON2HELP)

• Ayurveda (AYUCON2HELP)

• Biofeedback (BIOCON2HELP)

• Chelation (CHECON2HELP)

• Chiropractic care (COMCON2HELP)

• Special diet (DITCON2HELP)

• Folk medicine (FOKCON2HELP)

• Natural herbs (HERYCON2HELP)

• Healing ritual/sacrament (PRACON2HELP)

• Relaxation techniques (RELCON2HELP)
