FoodNet Population Survey

0920-1112

Exp Date: 04/30/2019

Circumstances of Change Request:

We recently completed cognitive testing of our survey instrument with 6 respondents. The interviews were conducted in Atlanta, Georgia and Silver Spring, Maryland. Respondents ranged in age from 18 to older than 65 years. Respondents identified several questions that were difficult to understand and answer. Therefore, we have amended our survey instrument to improve clarity, usability, and data quality.

Revised Survey Instrument:

We will discontinue use of Attachment D, the Population Survey Questionnaire version 20160224,

and replace it with Attachment D, the Population Survey Questionnaire version 20161005.

Discussion of Changes:

Across all modules, we added the day/date of the reference period to help respondents include the correct time frame when answering. We added examples to questions to help respondents determine the type of foods, animals, water, or medical conditions to include in their answer and help prompt respondents to think of exposures that are difficult to recall. We condensed questions that were tiring to answer and reordered modules so that similar questions are asked together. Where needed, we clarified the definitions of things, such as public or municipal water and wild game. The revised survey instrument is attached.

Burden:

There are no changes to the estimated burden per response (20 minutes), the number of respondents, or total estimated burden hours.
