Racial/Ethnic Differences in Cancer Prevention Beliefs: Applying the Health Belief Model Framework

Purpose. An understanding of each racial/ethnic group's beliefs about cancer prevention is important for designing/implementing interventions to reduce cancer-health disparities. The Health Belief Model was used to examine racial/ethnic differences in beliefs about cancer and cancer prevention. Design. The data were from the 2007 Health Information National Trends Survey, a biennial, cross-sectional survey using a random-digit-dial telephone frame and a mailing address frame. Setting. A weighted, nationally representative sample of American adults. Subjects. The sample consisted of 7452 individuals. Measures. Model construct variables (perceived susceptibility; perceived severity; perceived benefits; perceived barriers; cues to action; self-efficacy) and race/ethnicity were assessed. Analysis. The Rao-Scott chi(2) test and multivariate logistic regression assessed racial/ethnic differences. Results. The constructs self-efficacy, perceived benefits, and perceived susceptibility were significantly associated with race/ethnicity. The remaining three constructs were not statistically significant. Multivariate analysis revealed Hispanics were less likely to believe they could lower their chances of getting cancer than did African-Americans and whites. Hispanics, Asians, and African-Americans were more likely to believe they had a lower chance of getting cancer in the future than did whites. Conclusion. Culturally relevant health education/promotion interventions need to be developed and tailored to (1) empower Hispanics regarding their ability to prevent cancer and (2) educate racial/ethnic minorities about their susceptibility and risk perception for cancer.
