National Health Interview Survey
The National Health Interview Survey (NHIS) is the principal source of information on the health of the civilian noninstitutionalized population of the United States and is one of the major data collection programs of the National Center for Health Statistics (NCHS). The NCHS is part of the Centers for Disease Control and Prevention (CDC).
You can find both a brief fact sheet and a comprehensive description of the survey, including its purpose and scope, sample design, questionnaire content, and data collection procedures, on the CDC Web site.
The NHIS Core and Supplements
Each year, the NHIS includes a set of basic health and demographic items, called the Core questionnaire, plus additional sets of questions on current health topics, called Supplements.
- In 2002, 2007, and 2012, the survey included a Supplement on complementary health approaches.
- A detailed description of the processes used to develop the three Supplements was published in BMC Complementary and Alternative Medicine. This blog post mentions some of the updates in the 2012 survey.
- You can obtain NHIS questionnaires, datasets, and related documentation from the CDC.
- The 2012 adult and child complementary health approaches questionnaires are also available on the NCCIH Web site.
