Component Description

The Disability questionnaire (variable name prefix DLQ) provides respondent-level interview data on serious difficulty hearing, seeing, concentrating, walking, dressing, and running errands.

Eligible Sample

Participants aged 1 year and over were eligible. Questions asked varied by age group.

Interview Setting and Mode of Administration

DLQ 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.

Data Processing and Editing

The data were reviewed for completeness, consistency, and illogical values.

Analytic Notes

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.
