ASA24® Help for Respondents



There is a brief user orientation presented to respondents when they log into use the ASA24 respondent website.

The videos and downloadable ASA24 documents on this webpage have been created by the National Cancer Institute (NCI) as help guides for ASA24 respondents.

When respondents are using ASA24, they can also obtain help through two different buttons in the ASA24 system:

Help button - used to access the Help Center where respondent can access frequently asked questions (FAQs)

Home icon - used to navigate back to the home screen where respondents can view all the foods, drinks, and supplements already reported


Reporting Foods, Drinks, and Dietary Supplements: These short videos, available in English and Spanish, give a demonstration of how to use ASA24 to report a meal for a 24-hour recall. Researchers are invited to copy the links to these videos and share the videos with ASA24 respondents.
