Summary of 2019-2020 Questionnaire Changes

Summary

The NHANES interview consists of the following major components:

1. Household Screener Questionnaire (determines eligibility) and the Non-Response Bias Module (helps assess non-response bias) (SCQ)

2. Household Family Relationship Questionnaire (SFQ)

3. Household Sample Participant Questionnaire (HPQ)

4. Household Family Questionnaire (HFQ)

5. Mobile Examination Center (MEC) Interview (CAPI and ACASI)

6. Mobile Examination Center Dietary Interview (24-Hour Dietary Recall, Post-Dietary Recall Questions and Dietary Supplements)

7. Telephone Dietary Recall and Dietary Supplements

8. Special Follow-Up Questionnaires (FCBS) (Phone)

NHANES staff conducted a thorough review of the NHANES interview to make changes that reduce respondent burden and improve data utility. The rationale for these changes include:

• Removing questions that

  • are not used by researchers;

  • generate variables with small counts in response categories, which then cannot be used by researchers;

  • are no longer aligned with collaborator research interests; and

  • compliment exam or lab components that have been removed from NHANES.

• Modifying questions wording, response categories, skip patterns or instructions to:

  • harmonize NHANES with questions asked in the National Health Interview Survey (NHIS);

  • eliminate redundancy;

  • clarify confusing questions; and

  • respond to recommendations based on recent cognitive tests.

Three new questionnaire sections will be added (two in HPQ, one in HFQ); two sections will be discontinued (one in HPQ and one in HFQ); and 33 sections will be modified. 20 sections will not be modified.
