Component Description

The Cardiovascular Disease and Health section (variable name prefix CDQ) provides participant-level interview data on evaluating cardiovascular health and includes questions to assess the presence of angina pectoris as defined by the Rose questionnaire.

Eligible Sample

Participants aged 40 years and older were eligible.

Interview Setting and Mode of Administration

These questions were asked, in the home, by trained interviewers using the Computer-Assisted Personal Interview (CAPI) system.

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

Edits were made to ensure the completeness, consistency, and analytic usefulness of the data.
