Patient-reported experiences of care are an important focus in health disparities research. This study explored the association of patient-reported experiences of care with race and acculturation status in a primary care setting. 881 adult patients (African-American 34%; Hispanic--classified as unacculturated or biculturated--31%; Caucasian 33%; missing race 2%), in outpatient Family Medicine clinics, completed a written survey in Spanish or English. Consumer Assessment of Healthcare Providers and Systems (CAHPS) Clinician & Group (CAG) Survey Adult Primary Care instrument was used for experiences of care and Short Form-12 survey for health status. Controlling for other variables, race and acculturation were significantly associated with several CAG subscales. Hispanic patients gave significantly higher ratings for care experiences and expressed greater interest in shared decision making. Selected patient-reported measures of care are associated with patients' race and acculturation status (for Hispanic patients). We discuss implications for both provision and measurement of quality care.
