Gender identity has a significant impact on how an individual navigates and experiences the world. This chapter provides an overview of the intersections of social identities, offers an introduction to intersectionality, explores the impact of systems of oppression on mental health and well-being, and suggests strategies for incorporating principles of intersectionality and identity construction into counseling practice. Locating individual identity within sociopolitical contexts and recognizing the mutually constitutive interplay of social identities cause a significant shift in how identities are experienced, studied, and treated within counseling relationships and educational contexts. Many practitioners ground their work in social justice principles, recognizing that power, privilege, oppression, and discrimination impact sense of self as well as life experiences and expectations. Intersectionality has been deepened and broadened by scholars in education, counseling, sociology, psychology, cultural studies, history, queer theory, feminist studies, ethnic studies, and many other fields.
