Preferences in trust regarding the provision of cancer information among adults

Background:: 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. Methods:: 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. Results:: 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). Discussion: Significant differences in preferences regarding trust in cancer information occurred based on sociodemographic characteristics. Conclusion:: These finding suggest targeting specific population subgroups for information from sources they trust could be helpful in reducing disparities in trust.
