Objective: To evaluate the effect of patients' perceptions of providers' communication on medication adherence in hypertensive African Americans. Methods: Cross-sectional study of 439 patients with poorly controlled hypertension followed in community-based healthcare practices in the New York metropolitan area. Patients' rating of their providers' communication was assessed with a perceived communication style questionnaire,while medication adherence was assessed with the Morisky self-report measure. Results: Majority of participants were female, low-income, and had high school level educations, with mean age of 58 years. Fifty-five percent reported being nonadherent with their medications; and 51% rated their provider's communication to be non-collaborative. In multivariate analysis adjusted for patient demographics and covariates (depressive symptoms, provider degree), communication rated as collaborative was associated with better medication adherence (β = -.11, p = .03). Other significant correlates of medication adherence independent of perceived communication were age (β = .13, p = .02) and depressive symptoms (β = -.18, p = .001). Conclusion: Provider communication rated as more collaborative was associated with better adherence to antihypertensive medications in a sample of low-income hypertensive African-American patients. Practice implications: The quality of patient-provider communication is a potentially modifiable element of the medical relationship that may affect health outcomes in this high-risk patient population.
