Preferences in trust regarding the provision of cancer information among adults

Disparities associated with trust in health information exist warranting a need for research assessing this relationship among adults. Therefore, the aim of this study was to assess trust of cancer information among U.S. adults.

A weighted sample of 237,670,167 adults from the Health Information National Trends Survey (HINTS) from 2011-2014 was used for the analyses. Dependent variables were dichotomized answers to whether individuals trusted information from family/friends, the internet, or a doctor. Independent variables included age, sex, region, race/ethnicity, and cancer diagnosis to investigate associations between demographic factors and differences in trust. Logistic regression was run using R survey package.

There were statistically significant differences in trust based on race/ethnicity, age, and cancer diagnosis. Minorities were less likely to trust information from a doctor, with Hispanics more likely to trust information from the internet (OR=1.8 (95% CI 1.36,2.43)), and Non-Hispanic Blacks trusting information from family and friends (OR=1.5 (95% CI 1.06, 2.13)). Adults ≥45 years of age were less likely to trust the doctor 'a lot' (45-64 years: OR=0.6 (95% CI 0.50, 0.83); 65+ years (OR=0.7 (95% CI 0.54, 0.92)), but more likely to not trust information from family and friends or the internet. Patients with cancer were more likely to trust information from a doctor 'a lot' (78%; p=0.01).

Significant differences in preferences regarding trust in cancer information occurred based on sociodemographic characteristics.

These finding suggest targeting specific population subgroups for information from sources they trust could be helpful in reducing disparities in trust.
