In accordance with the terms of 5 CFR 1320, OMB has disapproved this collection of information. The purpose of the study is to determine whether there are differing response rates to surveys conducted via landlines and mobile phones. A great deal of research already exists on this topic and it is not clear what this survey would add to the existing literature. We recommend that FDA further review the existing literature. If, after such review, FDA still wishes to conduct this survey, please resubmit the package with a written explanation of how it will inform FDA's work that could not be duplicated by existing research.

The Center for Food Safety and Applied Nutrition (CFSAN) at the Food and Drug Administration (FDA) has been commissioning several waves of two national consumer surveys, the Food Safety Survey (FSS) and the Health and Diet Survey (HDS), to gather data on consumer knowledge, perceptions, and behaviors regarding food safety and nutrition. The purposes of the surveys are: to generate nationally representative estimates of knowledge, perceptions, and practices of interest at a given point in time; to track trends of the estimates over time; and to understand the relationships among knowledge, perceptions, and practices regarding food safety and nutrition and how these relate to demographic characteristics. Traditionally, the surveys have been administered via landline telephones and have used the random digit dialing (RDD) technique to recruit national samples of adults from households with landline telephone numbers. However, recent surveys show a notable decline of younger respondents in completed interviews. The under-representation of wireless-only or wireless-mostly adults in landline surveys, especially those in younger age groups, can affect national estimates of the prevalence of certain consumer perceptions, knowledge or behaviors, and understanding of the relationships between certain survey responses and demographic characteristics. The differences observed in these studies are pertinent and potentially problematic for the HDS and FSS. In sum, adults living in wireless-only and wireless-mostly households are less likely to appear in landline telephone samples and often possess characteristics that differ from those of adults in landline households. Thus, a telephone survey that still relies exclusively on landline phone calls to interview respondents may not produce results that are reliable and valid and/or may not yield results that are comparable to results from past landline surveys when this non-coverage problem was absent.
On behalf of this Federal agency, I certify that the collection of information encompassed by this request complies with 5 CFR 1320.9 and the related provisions of 5 CFR 1320.8(b)(3).
The following is a summary of the topics, regarding the proposed collection of information, that the certification covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control number;
If you are unable to certify compliance with any of these provisions, identify the item by leaving the box unchecked and explain the reason in the Supporting Statement.
