ASA24® Help Guides for Respondents


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

When participants 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 participant has access to frequently asked questions (FAQs)

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

Quick Start and Participant Help Guides

Researchers that are using the ASA24 system are encouraged to contact the ASA24 Support Team if there are tips that should be included in future troubleshooting or participant guides.
