While it is clear that self-reported racial/ethnic discrimination is related to illness, there are challenges in measuring self-reported discrimination or unfair treatment. In the present study, we evaluate the psychometric properties of a self-reported instrument across racial/ethnic groups in a population-based sample, and we test and interpret findings from applying two different widely-used approaches to asking about discrimination and unfair treatment. Even though we found that the subset of items we tested tap into a single underlying concept, we also found that different groups are more likely to report on different aspects of discrimination. Whether race is mentioned in the survey question affects both frequency and mean scores of reports of racial/ethnic discrimination. Our findings suggest caution to researchers when comparing studies that have used different approaches to measure racial/ethnic discrimination and allow us to suggest practical empirical guidelines for measuring and analyzing racial/ethnic discrimination. No less important, we have developed a self-reported measure of recent racial/ethnic discrimination that functions well in a range of different racial/ethnic groups and makes it possible to compare how racial/ethnic discrimination is associated with health disparities among multiple racial/ethnic groups.

Dr. Shariff-Marco earned her MPH from Columbia University and her PhD in social and behavioral sciences from Johns Hopkins University. Since joining DCCPS, Dr. Shariff-Marco has led a multidisciplinary team in the development of a racial/ethnic discrimination measure for use in health surveys and supported the Centers for Population Health and Health Disparities. Her research interests include assessing the role of social determinants in cancer health disparities and understanding the context of health behaviors.
Nancy Breen has served as an economist at the National Cancer Institute since 1991. Her research investigates how race, social class, gender, community factors, and health service diffusion shape cancer outcomes, especially cancer screening. Dr. Breen received her PhD in Economics from the New School for Social Research Graduate Faculty in 1988. Dr. Breen focuses on cancer screening, the entry point to health services delivery where disparities first emerge along the cancer continuum. Knowledge about screening and survey data led to Dr. Breen's appointment as NCI project officer to the California Health Interview Survey (CHIS) in 1999. As a member of the CHIS Multi-Cultural Task Force, Dr. Breen initiated research to develop and test a module on CHIS to measure self-reported discrimination in multi-cultural populations.

She is internationally known for her research on health disparities, and widely-regarded as a leading authority on ethnic-minority health. She developed the well-known African-American Acculturation Scale and several measures of ethnic and gender discrimination. She has received more than $10 million in extramural funding, and five national research awards including the American Psychological Association Dalmas Taylor Award for Lifetime, Distinguished Contributions to Research on Ethnic Minorities. Her areas of expertise are African American and Latino health and health disparities, with a focus on the role of acculturation, community poverty, ethnic discrimination, and residential segregation in the physical and mental health of American ethnic-minority groups.

At UNC-CH, Dr Reeve's work focuses on enhancing the application of patient-reported outcomes (PRO)(including symptoms, functioning, and quality of life) in clinical research and practice to improve the quality of care for pediatric and adult cancer patients. This includes the development of PRO measures using qualitative and quantitative methodologies and integration of PRO data in research and healthcare delivery to inform decision-making.

She received her PhD in Epidemiology from the University of California at Berkeley in 1989. An internationally recognized social epidemiologist, her work addresses conceptual frameworks to understand, analyze, and improve population health and reduce health inequities, including the ecosocial theory of disease distribution she has been developing since 1994; etiologic research on societal determinants of population health and health inequities; and methodologic research on improving monitoring of health inequities. She is author of Epidemiology and The People's Health: Theory and Context (2011) and editor of Embodying Inequality: Epidemiologic Perspectives (2004).
Gilbert C. Gee is Associate Professor in the School of Public Health at the University of California, Los Angeles.

Vickie M. Mays is Professor of Psychology in the College of Letters and Science and Health Services in the UCLA School of Public Health. She is the Director of the UCLA Center on Research, Education, Training, and Strategic Communication on Minority Health Disparities. She has a number of publications that address race-based discrimination, particularly as it applies to negative physical and mental health outcomes. Her work has examined the burden of discrimination in mental health outcomes and the cognitive and neural bases of the processes of discrimination. Mays is currently finishing an interview study of African American men over sixty-five, their experiences of race-based discrimination, and their coping.
