With the release of ASA24-US-2020, researchers can no longer register new studies using ASA24-US-2018. Researchers currently collecting data using the U.S. version of ASA24-2018 will need to transition these studies to ASA24-2020 by March 16, 2021.
As with ASA24-2016, the user interface for the 2018 version employs a responsive design, meaning the ASA24 system can be used on smartphones and tablets, in addition to laptops and desktops. This allows a broad range of participants to enter dietary intake data at any time and from any location with internet service.
The following features were new to the 2018 versions of ASA24:
- A feature that enables Respondents to report, save and modify recipes.
- Nutrient, food group and supplement databases include:
Other features of the US version of ASA24-2018 include:
- The user interface is written in HTML5. This enables ASA24 to work on all common web browsers. Previous versions required users to download the plug-in Microsoft Silverlight.
- Respondents can complete single- or multi-day food records (also known as food diaries) and 24-hour recalls, which expanded the types of studies and applications using ASA24.
- Researchers have the option to provide respondents with a Respondent Nutrition Report, which shows how their intake on the day they completed a 24-hour recall or food record compared to country-specific dietary guidance and nutrient requirements. For food records, researchers must provide the report to the respondent after obtaining it from the researcher website. For 24-hour recalls, the respondent can view the report directly after completing their recall.
- Data on supplement intake are collected at the same time as foods and beverages, rather than in a separate module. This allows participants to report supplement intake as part of what they consume on a given day, with corresponding time stamps that may be useful in examining patterns of intake across the day.
- Respondents can filter search results by food, beverage, and supplement categories. We also revised food terms to be more intuitive to help respondents more easily find foods, beverages, and supplements.
- Intuitive icons are used to facilitate editing of food terms and details.
- Tips and guidance are available within the respondent website via a Help Center and icons on the screen; and Quick Start Guides are available for study staff and respondents.
- System requirements and accessibility
- Evaluation and validation
- Register a study
- Help Guides for Respondents
Researchers are encouraged to report bugs that are encountered using either the respondent or researcher websites.View a detailed comparison of all versions of ASA24
