ASA24-2016 requires high-speed internet and is accessible by desktops, laptops, tablets, and smartphones. The user interface is written in HTML5. Unlike previous versions, this will enable ASA24-2016 to load on commonly used web browsers without downloading Microsoft Silverlight or other plug-ins.
The 2014 versions of ASA24 will continue to be available for use in studies until March 2017. Please note that the use of the 2014, 2012, and 2011 versions requires high-speed internet access and Microsoft's Silverlight browser plug-in, which can be freely downloaded. The Silverlight plug-in can be used in Internet Explorer, Firefox, and Safari; however, the plug-in will not run using the Chrome browser. As Silverlight is either no longer supported or will not be supported in the near future by most commonly used web browsers, all Researchers will be required to switch to ASA24-2016 by March 2017.
For Researchers using ASA24-2014 and ASA24-2011 who are considering switching to ASA24-2016 mid-study here are a few things to consider:
- You will have to register a new study and track which Respondents use the 2014/2011 versus 2016 versions. Data for recalls completed in ASA24-2014 (or ASA24-2011) will not be moved to ASA24-2016;
- As the graphic user interface is a complete redesign, you will need to consider any potential influence of the introduction of this change on your findings;
- As a result of updates to the underlying databases, data collected using versions prior to ASA24-2016 are not directly comparable (see a table comparing the features of all versions of ASA24). At some point in the future, guidance and SAS code will be made available to update analytic files from ASA24-2011/12 and ASA24-2014 versions, which used Food and Nutrient Database for Dietary Studies (FNDDS) 4.1 and an updated MyPyramid Equivalents Database (MPED) to FNDDS 2011-12 and to the Food Patterns Equivalents Database (FPED) 2011-12 used in ASA24-2016. It is not possible to rerun ASA24-2011 or ASA24-2014 Respondent data using ASA24-2016.
