This chapter presents an illustration of the complexities involved in studying ethnic and racial influences on psychosocial processes and how they are intimately tied to physical outcomes in later life. It focuses on psychology as a discipline, minority aging research during the last several decades has revealed the need for multidisciplinary and intersectional conceptual and research approaches. The chapter also focuses on the age, gender, socioeconomic, cultural, and racial and ethnic graded influences on life course development that eventuate in unequal burdens of psychological and physical health morbidity and mortality for certain groups in late life. No section on psychology could be complete without a discussion of religion and spirituality among racial and ethnic minorities. Generational processes are clearly implicated in ideas about the cyclical nature of poverty and health behaviors that are intricately linked with environmental factors and social influence.

This chapter presents an integrative approach to the psychological study of minority populations and the reduction of health disparities through positive nonmaterial resources. It provides a brief introduction to positive psychology and to the concept of early life origins of disease, highlighting the value of integrating these seemingly disparate literatures as a lens for studying health and broader aging processes among minority populations. Minority status whether based on ethnicity, gender, socioeconomic status (SES), citizenship, religion, or other factors is a robust determinant of health, well-being, and success across the life span and intergenerationally. Positive psychology is relevant to health and development particularly physiological and psychological adaptation to stress across the life span, and even across multiple generations among humans in general and among minority populations in particular. Health inequalities are the result of unique challenges to successful psychological and physiological adaptation faced by minority group members.
