The Automated Self‐Administered 24‐hour Dietary Recall (ASA24): publicly available from the National Cancer Institute (NCI)

Abstract

We will demonstrate the ASA24, an automated, web‐based, self‐administered 24 hour dietary recall instrument. The application uses state‐of‐the‐art computer technology, including a tutorial, graphic enhancements, and animated characters with audio‐language cues to guide participants. Respondents select foods consumed from a list based on the US Department of Agriculture's (USDA) survey database. Respondents find foods by browsing through food groups or typing and searching. Detailed questions about reported food, adapted from USDA's Automated Multiple Pass Method (AMPM) used in national dietary surveillance, collect information about preparation methods, additions to food, and portion size. Up to 8 sequentially‐sized digital pictures aid respondents in reporting portions. Respondents are given multiple opportunities to edit their food lists. A validation study to compare ASA24 to an interviewer‐administered recall using the AMPM is planned. ASA24, publicly available, can be accessed by researchers and sent to participants over the Internet or administered in a clinic/office. ASA24 makes feasible the inexpensive administration of multiple days of recalls in large‐scale studies or clinical research, enhancing researchers' ability to assess usual dietary intakes.
