Component Description

This is a set of questions on sleep habits and disorders. A subscale of eight questions related to general productivity, from the Functional Outcomes of Sleep Questionnaire (Weaver, et al.), is also included.

Eligible Sample

Participants 16 years of age and older were eligible.

Interview Setting and Mode of Administration

The questions on sleep disorders were administered in the home, using the Computer-Assisted Personal Interviewing-CAPI system, as part of the survey participant household interview.

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

Persons who reported sleeping 12 hours or more were coded as “12 or more hours” (SLD010H)

Analytic Notes

Although these data were collected as part of the household questionnaire, if they are merged with the MEC 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. Both of these are available on the NHANES website.
