Why Study Information Seeking? The shared/informed decision-making paradigm calls for
greater patient participation across the cancer care continuum.
Active information seeking results in greater patient participation.
The Internet revolution has drastically improved access to health information.
More informed patients report more positive health outcomes.

HINTS & Cancer Information Seeking
1. Who is seeking cancer information?
2. What information are they seeking?
3. Where are they seeking the information from?
4. What are their information seeking experiences like?
5. What are the consequences of their information seeking?

Who Seeks Cancer Information?
47.7% of the American public had at some point looked for information about cancer.
93.8% searched themselves; 6.2% relied on others.
– Of these 6.2%, majority (56.9%) relied on other family members.

Information Seeking Experiences Six item Information SEeking Experience (ISEE) scale
Based on your overall search for information on cancer, how much do you agree/disagree with: (HC-19)
– You wanted more information, but did not know where to find it.
– It took a lot of effort to get the information you needed.
– You did not have the time to get all the information you needed.
– You felt frustrated during your search for the information.
– You were concerned about the quality of the information.
– The information you found was too hard to understand.

Summary
A Iarge proportion of the American public engages in cancer-related information seeking.
Of these, a substantial percentage report suboptimal experiences, especially the underserved.
Past information seeking experiences are likely to shape people’s current levels of self-efficacy and cancer-related beliefs.
25
Conclusion
Given the positive impact of health information on patient outcomes, greater efforts are needed to facilitate cancer-related information seeking by the American public, especially for the underserved.
