ASA24 is a freely available Web-based tool that enables automated self-administered 24-hour recalls. ASA24 consists of a Respondent Web site used to collect recall data and a Researcher Web site used to manage study logistics and obtain data analyses. Two Respondent Web sites (English and Spanish) are currently available for registering new studies: ASA24-2014 (for adults) and ASA24-Kids-2014. Still available until March of 2015 are two previous versions of the Respondent Web site: ASA24-2011 (for adults) and ASA24-Kids-2012. Further information on the Respondent and Researcher Web sites is provided in the sections below.
