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 US Respondent Web sites (English and Spanish) are currently available for registering new studies: ASA24-2014 (for adults) and ASA24-Kids-2014. One Canadian version, ASA24-Canada-2014 (English only) is currently available for administration and the ability to obtain analyses for this will be available soon. 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.
