Interview Survey (CHIS). We used chi-square

tests to evaluate the prevalence of perceived discrimination and the reasons for perceived discrimination across racial groups. Setting: The 2001 CHIS, a telephone survey, one of the largest cross-sectional surveys ever conducted in the United States. Participants: Participants in this analysis were adults $18 years of age, interviewed from 55,000 households that took part in the survey. Interventions: Participants in the 2001 CHIS were asked ‘‘Thinking of your experiences with receiving health care in the past 12 months, have you felt you were discrimi-nated against for any reason?’ ’ Respondents who endorsed this item were asked about possible reasons for the discrimination. Main Outcome Measures: 1) Does the prevalence of perceived discrimination in health care differ between AI/ANs, AI/AN + Whites, African Americans, Asian Americans, and Whites? and 2) Do the reasons for perceived discrimination in health care vary by race or ethnicity
