The Physical Functioning questionnaire (variable name prefix PFQ) provides respondent-level interview data on functional limitations caused by long-term physical, mental, and emotional problems or illness.
Participants aged 3 years and over were eligible. Questions asked varied by age group.
PFQ was asked in the home, by trained interviewers, using the Computer-Assisted Personal Interview (CAPI) system.
Persons 16 years of age and older and emancipated minors were interviewed directly. A proxy provided information for survey participants who were under 16 years of age and for individuals who could not answer the questions themselves.
The data were reviewed for completeness, consistency, and illogical values.
Although these data were collected as part of the household questionnaire, if they are merged with exam data, exam sample weights should be used for the analyses.
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.
