ASA24® Researcher Website Features
The ASA24 researcher website allows researchers, clinicians, and educators to register a study, set study parameters, manage study logistics, and obtain output files.
The website allows researchers to set the following options:
- Collect 24-hour recalls or 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 session(s);
- For records, collect consecutive or non-consecutive day food records;
- Customize a study's opening and closing text scripts and study logo on the respondent website;
- Turn on optional modules to query where meals were eaten, whether meals were eaten alone or with others, television and computer use during meals, source of foods consumed, 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 Patterns Equivalents Database (FPED) and the 2007 Eating Well with Canada's Food Guide (Canadian versions only) for ASA24-2020, ASA24-2018, ASA24-Canada-2018, ASA24-2016 and ASA24-Canada-2016 and the MyPyramid Equivalents Database (MPED), for ASA24-2014, and ASA24-Kids-2014.
