Experts Recommend National Surveillance Program

• To monitor changes in health information environment over time

• To explore usage across channels and sources nationally

• To combine channel usage with knowledge, attitudes, behaviors

• To build an evidence base for planners, administrators, communicators, practitioners, and policy makers

Factors influencing choice• Anonymity• Interactivity• Timeliness• Clarity• Credibility• Content• Cost

Channel attributes (affordances) 3

• Accessibility• Availability (e.g., 7 X 24)• Bandwidth• Responsivity • Directionality

Stage 1: Build Awareness Stage 2: Support Information Seeking

Select Channel for Obtaining Information

• Formal Sources (e.g., family doctor)

• Commercial Sources (e.g.,TV, newspapers)

• Informal Sources (e.g., friends and relatives)

Cancer knowledge• Personal risk• Preventability• Relative prevalence• Desire to change/barriers to change• Myths and misinformation• Specific cancer knowledge

Attitudes toward• Channel (channel attributes)• Personal ability (self-efficacy)• Prevention/treatment (response-efficacy)• Sources (comparative preference)

Personal characteristics• Age• Gender• SES• Family history• Education• Cultural background• Language(s) spoken• Environmental exposure• General health• Direct experience with cancer• Motivation to change
