Explaining cancer information avoidance comparing people with and without cancer experience in the family.

Objectives: Cancer information avoidance (CIA) serves as a barrier to preventive efforts. To learn how to combat this barrier, we aim to examine predictors of CIA in populations with and without cancer experience in the family, which are addressed differently in cancer prevention, according to specific informational barriers.

Methods: A subsample of people with and without cancer in the family (n = 2,757) of an online survey with a sample stratified for the German population by age, gender, education, and region was conducted via an online access panel. The survey instrument was adapted from the Health Information National Trends Survey. Separate stepwise regression analyses were conducted.

Results: Only a comparatively small proportion of the variance in CIA was explained by the predictors, ranging from R²  = .148 for people without cancer experience to R²  = .180 for participants with cancer experience in their family. Across the groups, the findings showed that people who were fatalistic about the risk of cancer, less health literate, who perceived less social pressure to be informed, and were less trusting in information sources more often avoided cancer information.

Conclusions: Our findings identify relevant target groups to be addressed and barriers to be removed for cancer communication efforts. Adequate information provision can be supported by programs for fostering health literacy and social network diffusion strategies.
