Component Description

The medical conditions section (variable name prefix MCQ) provides self-reported personal-interview data on a broad range of health conditions.

Eligible Sample

All participants aged 3-15 years were asked to respond to this section. The questions were asked of all survey participants by proxy. Frequency counts were verified during the preparation of the file.

Interview Setting and Mode of Administration

These questions were asked, in the home, by trained interviewers using the Computer-Assisted Personal Interviewing (CAPI) system. The survey questionnaire is available on the NHANES website (https://www.cdc.gov/nchs/nhanes/index.htm).

Quality Assurance & Quality Control

The CAPI system is programmed with built-in consistency checks to reduce data entry errors. CAPI also uses online help screens to assist interviewers in defining key terms used in the questionnaire.

Data Processing and Editing

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

Analytic Notes
