The physical functioning section (PFQ) provides self-reported data on functional limitations caused by long-term physical, mental, and emotional problems or illness. It can be used to assess an individual’s level of disability.
All survey participants 5 or more years of age were eligible. Those less than 18 years of age were asked about receiving Special Education or Early Intervention Services. Respondents 5 to 19 years of age were asked about mobility and those 20 or more years of age were asked about their ability to work.
The questions were asked in the household interview as a part of a computer-assisted personal interview (CAPI).
Edits were made to ensure the completeness, consistency, and analytic usefulness of the data.
Since the questions were asked in the home interview, the interview sample weights may be used in their analysis. However, if the data is joined with data from the Mobile Examination Center (MEC), the MEC sample weights should be used.
Please refer to the NHANES Analytic Guidelines and the on-line NHANES Tutorial for further details on the use of sample weights and other analytic issues.
