Cancer-Focused News Coverage and Information Seeking Jeff Niederdeppe, Dominick Frosch & Robert Hornik Center of Excellence in Cancer Communication Research Annenberg School for Communication University of Pennsylvania

2 The Context Shift toward viewing patients as active consumers of health care Rapid growth in the availability of health information (e.g., on the Internet) To what extent do people react to public information about cancer by seeking additional cancer-related information?

3 Prior Research Cancer information seeking research has focused primarily on cancer patients Studies examining effects of news coverage have found associations between news coverage and preventive health behavior Studies have found large impact of high-profile news events (e.g., Katie Couric, Magic Johnson, Ronald and Nancy Reagan)

4 Research Questions Test relationship between routine news coverage and cancer-related information seeking among general population Explore two moderating hypotheses 1. Cancer experience (personal or close friend or family member) 2. Attention to health-related news topics

5 Measuring Cancer-Focused News Coverage Lexis-Nexis database search for cancer-related articles in the Associated Press 1. Calibration sample (June 1–June 7, 2003) l Coders identified cancer-focused articles from cancer as search term l Kappa = Validation samples (26 random days, One per week) l Developed more sophisticated search term to capture only relevant articles

6 Recall and Precision of Validated Search Term Search term recall = 0.86, precision = 0.79 Applied search term to HINTS data collection period to identify cancer-focused news articles between October 21, 2002 and April 13, 2003 Each story was assumed to have a half-life of 1 day (Fan, 2003). Mean = 1.73/day.

7 Variability in Cancer-Focused News Coverage

8 Independent and Dependent Variables Merged news coverage data to HINTS by date of interview Cancer-focused news coverage in the week preceding the interview Cancer-related information seeking 5.7% of the sample reported seeking cancer-related information in the past week

9 Analytic Approach Multivariate logistic regression assessed effect of news coverage on the odds of cancer information seeking in past week Interactions to test moderating hypotheses Covariates include age, gender, ethnicity, education, Internet access Plot model predicted values by IVs and moderators

10 Overall Effects of News Coverage on Info Seeking OR = 1.04, p > 0.10

11 Moderating Effects of Attention to Health-Related News Interaction (p < 0.02)

12 Discussion Effects of cancer-focused news coverage appear to extend beyond major news events Previous research suggests that public health advocates have potential to affect the amount of cancer-focused coverage Nevertheless, effects only observed among those who already pay close attention to health-related news coverage Those who seek primarily use Internet to do so

13 Limitations 1. No evidence (yet) that seeking behavior leads to favorable health outcomes among general population 2. Relatively small proportion (5.7%) of survey respondents sought information in past week Only six months of data collection, which may reduce variability in cancer news coverage Effect was observed in spite of these limitations

14 Implications and Future Directions Potential for widened knowledge gap? How to reach those who dont pay close attention to health-related news coverage? Many adults may require active efforts by health advocates to disseminate information relevant to prevention, screening & treatment What conditions lead people to seek health information, and how do people make sense of the complex health info environment?
