Development and Testing of a Patient-facing Educational Tool About Liver Cancer Prevention

Description

Primary Objectives:

* To ensure the text for the site is understood by participants, participant comprehension will be measured qualitatively through cognitive testing. Adjustments will be made to the content, messages, and layout iteratively until interviewer notes show no large discrepancies between participant understanding and the meaning of the text.
* To ensure the site is easy to use, usability will be measured qualitatively through usability testing. Adjustments will be made to the functionality of the patient-facing portions of the web-based tool iteratively until interviewer notes indicate that participants are able to input their risk factors and download the personal summary on their own.

Secondary Objectives:

* To describe whether the site is acceptable to users, acceptability will be measured (as part of usability testing) with the Ottawa Acceptability Measures.
* To describe participants’ knowledge of liver cancer risk factors, knowledge will be measured (as part of usability testing) with Knowledge Questions developed for this study.
