The ASA24 Researcher Website allows researchers, clinicians, and teachers to register a study, set study parameters, manage study logistics, and obtain outut files.
The Website allows Researchers to set the following options:
- Collect 24-hour recalls, and for the 2016 versions of the ASA24 system, food records;
- For recalls, query intake from midnight-to-midnight of the previous day or for the past 24 hours (starting at the time of login);
- Have Respondents complete a recall in one sitting (with breaks of no more than 30 minutes) or over a longer specified time interval;
- Have Respondents complete a recall in a single or multiple sessions;
- For records, collect consecutive or non-consecutive day food records (2016 versions only);
- Customize a study's opening and closing text scripts and study logo on the Respondent Website;
- Turn on optional modules to query the location of meals, with whom meals were eaten, television and computer use during meals, and supplement intakes.
- Provide Respondent Nutrition Reports to participants
- In the Demonstration version website, the optional Respondent Nutrition Report feature is turned on and the report can be viewed after a 24-hour recall has been entered.
In addition, the Website enables Researchers to:
- Monitor study progress and obtain a variety of reports, including statistics for complete, incomplete, and upcoming recalls or records for each participant;
- Manage Respondent user accounts;
- Use a wizard to generate recall dates for studies defined as "scheduled;"
- View information about recalls and records, including number of logins, session duration, language, calories, number of eating occasions, and number of food codes;
- Obtain analysis files for 65 nutrients and 37 food groups (Note: Food groups are not included in Australian version of analysis files) based on the following databases:
- Food and Nutrient Database for Dietary Studies (FNDDS) for U.S. versions.
- Canadian Nutrient File (CNF) for Canadian versions and the Australian Food, Supplement and Nutrient Database (AUSNUT) the Australian version.
- United States Department of Agriculture's (USDA) Food Pyramid Equivalents Database for ASA24-2016 and ASA24-Canada-2016 and the MyPyramid Equivalents Database (MPED), for ASA24-2014, and ASA24-Kids-2014. These provide food group estimates of consumed items.
