ABSTRACT
BACKGROUND
Given the persistence of health and health-care disparities among Latinos in the United States and evidence that discrimination affects health and health care, an investigation of the relationship between perceived discrimination and quality of health care among Latinos is warranted.
OBJECTIVE
To examine the relationship of perceived discrimination (in general and in regard to doctors and medical personnel) with self-reported quality of health care and doctor-patient communication in a nationally representative Latino population sample.
PARTICIPANTS
Participants were 1,067 Latino adults aged ≥18 years living in the US selected via random-digit dialing. Telephone interviews were conducted in 2008 during Wave 2 of the Pew Hispanic Center/Robert Wood Johnson Foundation Hispanic Healthcare Survey.
RESULTS
US-born Latinos were twice as likely to report general discrimination as foreign born: 0.32 SD versus −0.23 SD (P < 0.001) on the Detroit Area Survey (DAS) discrimination scale. Higher DAS discrimination was associated with lower self-reported quality of care in US-born Latinos [OR = 0.5; 95% CI (0.3, 0.9); P = 0.009]. For foreign-born Latinos, report of any doctor or medical staff discrimination was associated with lower quality of care [OR = 0.5; 95% CI (0.3, 0.9); P = 0.03], but the DAS was not. For US-born Latinos, doctor discrimination and higher DAS were jointly associated with worse doctor-patient communication. For foreign-born Latinos, the effect of discrimination on doctor-patient communication was significantly smaller than that observed in US-born Latinos.
CONCLUSIONS
Given the association between perceived discrimination and quality of care, strategies to address discrimination in health-care settings may lead to improved patient satisfaction with care and possibly to improved treatment outcomes.

INTRODUCTION
Minorities in the US are more likely to experience health and health-care disparities than their majority counterparts. While many factors may contribute to these disparities, discrimination has been shown to be one of the most prominent.1,2 The body of literature linking discrimination with health and health-care disparities has traditionally concentrated on African Americans, and has only recently begun to focus on the Latino population,3–5 perhaps due to recent census findings indicating that the Latino population is the largest minority population in the US.6,7 Health-care disparities that Latinos experience as a result of discrimination, and the subsequent effects on quality of health care, present issues of great social and economic significance for the entire populace.
In addition, perceived discrimination has been established as a correlate of health-care access and health-care behavior in a number of ways. Perceived discrimination has been found to be associated with cancer screening8, health-care under-utilization3, receipt of diabetes management indicators such as the hemogloblin A1C test, foot exam and blood pressure exam9 and reported delays in filling pharmacy prescriptions10. The existence of racial/ethnic and other disparities in care especially among vulnerable populations gives further impetus to understanding how quality of care is impacted by perceived discrimination. Trivedi and Ayanian showed that vulnerable persons who perceived discrimination were less likely to receive testing for CVD, flu shots and eye exams1.
Previous studies have examined perceived discrimination among Latinos in the US health-care system.5 The 2004 Behavioral Risk Factor Surveillance System survey showed that 5.2% of Latinos perceived discrimination in health-care settings, while only 2% of non-Latino whites reported discrimination.11 The nature of this discrimination was further elucidated by research5,12 that found that Latinos born in the US were more likely to report discrimination based on their sociodemographic and sociocultural factors. However, Latinos with higher socioeconomic status (SES) and health insurance reported experiencing less discrimination when receiving health care.12 In contrast, other studies have shown that higher SES is associated with greater perception of discrimination.5
Perceived discrimination among Latinos has been shown to produce effects both in and out of the provider’s office. In the hospital setting, for example, Latina patients have rated their obstetrical services experience lower than non-Latino whites with regard to respect, information and education, physical comfort and emotional support.13 The effects of this discrimination have extended well beyond hospitals, however, and have prevented Latinos from seeking health-care services. For example, Nadeem et al. found that for Latinas, an increased stigma in seeking mental health-care services kept them from accessing the services they needed.14 Furthermore, perceived discrimination has been related to greater psychological distress and lower self-esteem.15 Discrimination has also been associated with conditions such as coronary heart disease, high blood pressure and compromised mental health.4,16,17
Despite the existence of the above-mentioned studies, perceived discrimination among the Latino population remains a relatively understudied area.3,5,19 Awareness and understanding of discrimination-induced health-care disparities are needed to mobilize systematic and systemic reform efforts.20 This study contributes to a growing body of literature examining discrimination among Latinos by using a nationally representative database to examine general and health-care-specific discrimination experienced by specific groups of Latinos in the US. In this study, we examine the association between perceived discrimination and two measures of quality of care: patient report of quality of care in the past 12 months and quality of doctor-patient communication.
METHODS
Sample
Study participants were part of a stratified, random-digit dialing telephone survey (the Pew Hispanic Center/Robert Wood Johnson Foundation Latino Health Survey)21 of N = 3,899 adult Latinos (aged ≥18 years) designed to produce a statistically representative sample of Latinos in the contiguous US. Respondents were identified as Latino if they answered yes to the question, Are you, yourself, of Hispanic or Latino origin or descent such as Mexican, Puerto Rican, Cuban, Dominican, Central or South American, Caribbean or some other Latin American background? Initial telephone interviews (Wave 1) were conducted in summer 2007 and had a response rate of 39.5%. Participants were called again in spring 2008 for a second interview (Wave 2), focusing on chronic disorders and medical care received. Subjects for this study are the N = 1,067 persons who completed the Wave 2 interview.
Wave 1 sampling weights were calculated as the inverse probability of selection. Post-stratification weight adjustment for Wave 2 consisted of an adjustment of Wave 1 sampling weights so that the sum of the weights by sex, age, nativity and education matched those of Latinos in the March 2007 supplement of the Current Population Survey.22 This post-stratification weight adjustment was minor, and Wave 2 participants were not statistically different from other Wave 1 participants on any demographic measure.
Measures
For this study, two measures of discrimination were used: the Detroit Area Study (DAS) discrimination scale consisting of nine 6-point items,23,24 and a measure of doctor or medical staff discrimination from the Commonwealth Fund Health Quality Survey consisting of three yes or no items; see Appendix for items.25 The DAS scale had range 0–39, median 4, mean 6.7, SD 8.4 and Cronbach’s α = 0.87. For all analyses, the DAS discrimination scale was scaled to have mean 0 and SD 1, and treated as a continuous measure. The doctor or medical staff discrimination items were converted into a single dichotomous variable with zero indicating no to all three items and one indicating a yes to any one of the items.
There were two outcome measures. The first was a 5-point measure of self-reported quality of health care received in the past year, with responses excellent, very good, good, fair and poor. The second outcome measure was a scale comprised of four 5-point items from the Interpersonal Processes of Care Survey Short Form,26 which reflects the quality of communication between doctors and other health professionals and the study participant; see Appendix for items. This scale is referred to as the doctor communication scale in this study and had range 0–16, median 10, mean 10.1, SD 4.5 and Cronbach’s α = 0.75.
Statistical Analyses
Weighted sex-age adjusted means of the DAS discrimination scale were calculated along with weighted sex-age adjusted percentages of respondents who answered yes to any of the doctor discrimination items in Table 1. Significance tests for proportions were performed using a Rao-Scott statistic for the Pearson χ2 test for contingency tables27–29, and tests for means were done using design-based Wald tests30.

Self-reported quality of care was analyzed as the outcome variable in weighted ordered logistic regressions in Table 2. The doctor communication scale was the outcome in weighted linear regressions in Table 3. Design-based Wald tests30 were conducted to test joint effects of categorical variables. Figures 1 and 2 give adjusted means from weighted regressions. Standard error estimates for all analyses were adjusted for the sampling design using a first-order Taylor series approximation. All analyses were conducted using the svy suite of commands from Stata statistical software version 10.131.

RESULTS
The first data column of Table 1 shows the percentage of respondents who answered yes to any of the three items indicating perception of discrimination from doctors or medical staff in the past 2 years (see Appendix). Overall, only 19% of all persons reported any discrimination from doctors or medical staff. Doctor or medical staff discrimination was significantly associated with age (P = 0.02) with younger persons (18–29 years) more likely to report discrimination (22%) than persons aged ≥65 years. The only other significant association of doctor discrimination and the variables shown in Table 1 was between doctor discrimination and self-reported health status (P = 0.005). Persons with poor health status reported dramatically more doctor or medical staff discrimination (39%) than those with better health status (11% for those reporting excellent health and 14% for those reporting very good health).
Table 1 shows the mean value of the DAS discrimination scale by demographics and self-reported health status. The overall mean of zero on this scale reflects the standardization of the scale to mean 0 and SD 1. Unstandardized, the overall DAS mean was 6.7 (with range 0–39), which corresponds to an average answer slightly below the level of the response “less than once a year” for each of the nine items on the scale (see Appendix). The DAS responses were not significantly different by sex, but were highly associated with age (P < 0.001) with younger participants reporting the most discrimination. US-born Latinos reported more discrimination than the foreign-born, with the US born far more likely to report discrimination compared to the foreign born (0.32 SD versus −0.23 SD); however, the age-adjusted means for the foreign born did not significantly differ by the number of years in the US. Language of interview was associated with perceived discrimination to a similar degree as nativity, with those who were interviewed in English or a mix of English and Spanish more likely to report discrimination than Spanish interviewees (0.31 SD versus −0.22 SD). Reported discrimination on the DAS scale did not differ significantly by education, nor was self-reported health status associated with DAS.
Table 2 shows ordered logistic regression models for self-reported quality of health care in the past year with separate models for US-born and foreign-born Latinos. Included in the models are terms for any discrimination from doctors or medical staff, the standardized DAS discrimination measure (yielding a beta coefficient), demographics, health insurance and self-reported health status. Models for both US-born and foreign-born Latinos yielded the same odds ratio (0.5) for doctor discrimination; however, only in the foreign-born model did it reach statistical significance (P = 0.03). The DAS discrimination scale, however, was significantly associated with lower quality of care for the US born [OR = 0.5 (0.3, 0.9); P = 0.009], but was not significant for the foreign born [OR = 0.9 (0.7, 1.2); P = 0.6]. A test of the difference for the DAS odds ratio for the US born compared to the odds ratio for the foreign born was significant at P = 0.03. In the model for US-born Latinos, the only other significant odds ratio was that for very low education (0–8 years). In contrast, for foreign-born Latinos, younger adults (18–29 years), health insurance and self-reported health status were all significantly associated with quality of care.
Table 3 shows linear regression models for the doctor communication scale (see Appendix). For US-born Latinos, both any doctor or medical staff discrimination and DAS terms were significantly associated (P < 0.001 and P = 0.03, respectively) with doctor communication, with persons reporting more discrimination having worse doctor communication. No other terms were significant in the model for the US born. For foreign-born Latinos, these discrimination terms were marginally nonsignificant. A test of the difference for the doctor discrimination coefficient for the US born [−3.5 (−5.1, −2.0)] compared to the coefficient for the foreign born [−1.2 (−2.5, 0.0)] was significant at P = 0.02. Notably, the only significant term in the foreign-born model was insurance, and only marginally so.
Figures 1 and 2 illustrate the effect size of the self-reported experience of doctor or medical staff discrimination. Figure 1 shows the mean level of self-reported quality of care by nativity for persons reporting any doctor or medical staff discrimination and for those reporting no discrimination. Figure 2 is similar except that the outcome plotted is the mean level of the doctor communication scale. Means in Figure 2 were adjusted for sex, age and education, and means in Figure 1 were adjusted for these variables and self-reported health status as well (see Methods).
In Figure 1, the difference in self-reported quality of care for US-born Latinos who report any doctor discrimination compared to those who report none is 0.7 lower [95% CI (0.2, 1.2); P = 0.004], where one unit represents one step on the response (i.e., the difference between very good and good). For foreign-born Latinos, the difference is smaller: 0.4 lower self-reported quality of care [95% CI (0.1, 0.6); P = 0.006].
In Figure 2, the difference in the doctor communication scale for US-born Latinos who report any doctor discrimination compared to those who report none is 4.1 lower [95% CI (2.5, 5.6); P < 0.001]. For foreign-born Latinos, the difference is much smaller: 1.7 lower on the doctor communication scale [95% CI (0.7, 2.7); P = 0.001].
DISCUSSION
Perceived discrimination was associated with quality of care measures in this nationally representative sample of US Latinos. However, this association was much stronger among US-born Latinos than among the foreign born. Of all correlates of quality, discrimination had the strongest effect as one in five persons reporting perceived discrimination from medical personnel within the past 2 years. We looked at two measures of discrimination, one a measure of general discrimination, the Detroit Area Study (DAS) discrimination scale, and the other a measure of perceived discrimination from doctors or medical personnel. In a model of self-reported quality of care for US-born Latinos, with both discrimination measures as independent variables, the DAS scale was significantly associated with quality of care (after controlling for sociodemographics and health status), but perceived doctor discrimination was not. In the same model for foreign-born Latinos, only doctor discrimination was associated with self-reported quality of care. In models of the quality of doctor-patient communication, both discrimination measures were significant for the US born, but for the foreign born, both were marginally nonsignificant.
The finding of a greater association between perceived discrimination and self-reported quality of care measures in the US born compared to the foreign born has several possible explanations. The first possibility is that US-born Latinos experience more discrimination than foreign-born Latinos because they interact more closely with non-Latinos in the US and seek health care in the same settings as non-Latinos—and that the care they receive in these settings is below the level that they perceive non-Latinos receive.
The second possibility is that US-born Latinos because of their English-language abilities and greater understanding of US culture are more vigilant in monitoring their patient-provider relationship and are better able perceive when receipt of lower quality of care is connected to discrimination than are foreign-born Latinos. It may be that foreign-born Latinos are “protected” from perceiving discrimination. Other studies have suggested a similar protective factor of lower acculturation.5,32,33 Previous authors have suggested ethnic identity as one of many possible buffers of discrimination, and foreign-born Latinos may benefit from this factor.34,35 However, in this study, we did not find associations among discrimination and education, age or income that were found in prior studies of discrimination.36
The third possibility is that among US-born Latino there is a larger subgroup of “pessimists” regarding their life in the US than among the foreign born—and these pessimists rate their experiences in general more negatively—so they have perceptions both of more discrimination and of lower quality of health care.
Based on our results, the third possibility seems the least likely. We found that levels of perceived discrimination from doctors or medical staff to be similar among the US born and the foreign born. If there were more “pessimists” among the US born, there should be a larger proportion reporting discrimination in the health-care setting among the US born than among the foreign born. The strongest association that we found was between perceived doctor or medical staff discrimination and doctor-patient communication in the US born. This seems to support the second possibility that US-born Latinos are better able to perceive the connection between discrimination and lower quality of care when it exists. The strong association between general discrimination (as measured on the DAS scale) and self-reported lower quality of care among the US born seems to support the first possibility—those with the most interaction with US culture experience both more discrimination and a perceived lower relative quality of care.
Still a fourth possible explanation explaining why US born Latinos who perceive discrimination report lower quality of care could be that they have switched providers in the previous year. It is likely that many Latinos experienced discrimination prior to the year in which the health-care quality questions referred to. This in turn may explain for the higher rates of perceived discrimination as well as the lower rates of perceived quality of health care received.
The association this study found between poor self-reported health status and perceptions of discrimination from doctors or medical staff is of concern. In Piette et al.’s 37 work with diabetic patients, a similar association was found where 14% of the study’s participants reported experiencing health-care discrimination during the prior year, including discrimination due to their race (8%), education or income (9%), age (7%) and sex (10% of women). In the present study, respondents with poorer health status reported more than three and a half times the rate of discrimination in the health-care context.
Limitations
The study is cross-sectional, and arguments of causation cannot be made. The mean of general discrimination assessed on the DAS scale is relatively low; on average, discriminatory experiences are occurring only a few times a year, and only about one in five Latinos reported any discrimination from doctors or medical personnel in the past 2 years. The question remains whether such a small level of discrimination can be clinically significant. However, it may be that attributes of poor quality of care and poor patient-provider communication, such as rushed care, rudeness, or arrogance on the part of doctors or medical staff, are associated in respondents’ minds with perceived discrimination. The connection between general discrimination not necessarily in a medical setting and quality of care may be even more tenuous.
Looking at general discrimination and discrimination in a medical setting jointly in models as we have done may give some insight into possible factors explaining the association. Although the DAS discrimination scale and the doctor discrimination measure had a strong positive association with each other, they were not so collinear as to create problems in the models presented here; when the discrimination terms were included in the models separately, results were similar.
As in all telephone surveys, the representativeness of the study sample to Latinos in general can be questioned. Wave 2 follow-up was also limited in this study; due to financial constraints there was a short time window for completing callbacks. However, our analysis of the Wave 2 sample compared to the rest of the Wave 1 showed no significant differences on any demographic characteristic. Sample size may have been a greater limitation. Our sample size was insufficient to fully dissect the associations among general discrimination, doctor discrimination and quality of care and to identify the subgroups within the nativity groups that were responsible for the overall associations found.
CONCLUSIONS
The results from this study give a better understanding of the relationship between perceived discrimination and perceived quality of care among US Latinos. It demonstrated that factors such as discrimination may impinge on quality of care. For health-care providers and policymakers seeking to have an impact on health-care quality, focusing on discrimination may prove to be a fruitful endeavor. Discrimination toward both highly acculturated English-speaking US-born Latinos and lower-acculturated Spanish-speaking Latinos should be addressed. Future research is needed to investigate how interventions can be tailored so that they address perceived discrimination in health-care experiences for Latinos, perhaps with different approaches for the US born than the foreign born. Reducing discrimination may be difficult to achieve, but the results of this study suggest that quality improvement interventions must take discrimination into account.

Appendix
Detroit Area Survey (DAS) Discrimination Scale
This scale 22,23 is based on responses to the following nine items:
In your day-to-day life how often have any of the following things happened to you:
You are treated with less courtesy than other people.
You are treated with less respect than other people.
You receive poorer service than other people at restaurants or stores.
People act as if they think you are not smart.
People act as if they are afraid of you.
People act as if they think you are dishonest.
People act as if they they’re better than you are.
You are called names or insulted.
You are threatened or harassed.
Would you say this has happened to you…?
Almost every day
At least once a week
A few times a month
A few times a year
Less than once a year, or
Never
Doctor or Medical Staff Discrimination
This measure, derived from questions from the Commonwealth Fund Health Quality Survey 24, is based on yes or no responses to the following three items:
Now, thinking about all of the experiences you have had with health-care visits in the last 2 years, have you ever felt that the doctor or medical staff you saw judged you unfairly or treated you with disrespect because of…
Your race or ethnic background
How well you speak English
Your ability to pay for the care or the type of health insurance you have
The discrimination measure constructed from these items and used in all analyses was a dichotomous variable with 1 indicating a “yes” answer to any of these three items and 0 indicating “no” answers to all three items.
Doctor Communication Scale
This scale was based on the following four items from the Interpersonal Processes of Care Survey Short Form25:
How often did doctors or health professionals…
Really find out what your concerns were
Clearly explain their advice and recommendations
Clearly explain the side effects of the medication(s)
Ask if you were having problems following their advice and recommendations
Would you say…?
Never
Rarely
Sometimes
Usually, or
Always
