Effects of patient-provider race concordance and smoking status on lung cancer risk perception accuracy among African-Americans

Abstract

Background: Communication of lung cancer risk information between providers and African-American patients occurs in a context marked by race-based health disparities. Purpose: A controlled experiment assessed whether perceived physician race influenced African-American patients' (n = 127) risk perception accuracy following the provision of objective lung cancer risk information. Methods: Participants interacted with a virtual reality-based, simulated physician who provided personalized cancer risk information. Results: Participants who interacted with a racially discordant virtual doctor were less accurate in their risk perceptions at post-test than those who interacted with a concordant virtual doctor, F(1,94) = 4.02, p =.048. This effect was amplified among current smokers. Effects were not mediated by trust in the provider, engagement with the health care system, or attention during the encounter. Conclusions: The current study demonstrates that African-American patients' perceptions of a doctor's race are sufficient to independently impact their processing of lung cancer risk information. © 2013 The Society of Behavioral Medicine (outside the USA).
