Although health status of racial and ethnic groups in the U.S. has improved, health disparities between minority and non-minority groups have increased. To promote advancements in health and social services research, culture-fair measures are needed. In this volume, established researchers, many of whom are investigators for the National Institute on Aging's Resource Centers for Minority Aging Research (RCMAR), address the state-of-the-art in multicultural measurement and set the stage for more work toward the goal of accurate assessment. Chapters examine methodological issues and measurement of acculturation, ethnic identity, socioeconomic status, social support, cognitive function health, mental health, quality of life religiosity, and ethnicity.
