Respondent Web Site Features

The ASA24 Respondent Web site guides the participant through the completion of a 24-hour recall for the previous day, either from midnight to midnight or for the past 24-hours, using a dynamic user interface. The instrument:

  • provides an animated guide and audio and visual cues to instruct participants and enhance use in low-literacy populations and in children (with options to turn off the guide and/or the audio);
  • asks respondents to report eating occasion and time of consumption;
  • includes optional modules to query where meals were eaten, whether meals were eaten alone or with others, and television and computer use during meals;
  • flows as per modified USDA Automated Multiple-Pass Method (AMPM) 24-hour recall;
  • allows respondents to report foods and drinks by browsing by category or searching from a list of food and drink terms derived from the National Health and Nutrition Examination Survey (NHANES);
  • asks detailed questions about food preparation, portion size, and additions so that food codes from USDA’s Food and Nutrient Database for Dietary Studies (FNDDS) can be assigned; the 2014 versions also provide an option to query respondents about food source;
  • uses images to assist respondents in reporting portion size;
  • allows the respondent to add or modify food and drink choices at multiple points during the interview;
  • includes an optional module to query dietary supplement intake based on supplements reported in NHANES;
  • is available in English and Spanish; and
  • is accessible by individuals with speech and hearing impairments.

The Respondent Web sites do not provide any direct feedback to respondents. Instead, researchers can obtain analysis files from the Researcher Web site and contact respondents with any findings they choose to share.
