This book guides readers through the origins, development, and key concepts of liberation psychology; its methods, including participatory action research; its manifestation in clinical practice; its potential future applications; and its relation to social activism and social justice movements. Liberation psychology challenges traditional Western‑based psychology by offering an emancipatory approach to understanding and addressing oppression among individuals and groups. This book provides an understanding of liberation psychology that enhances the work of all students, researchers, and practitioners in psychology by raising awareness of discrimination, inequality, and issues related to intersectionality; affirming cultural identities; fighting oppression; and promoting social change to help alleviate human suffering and support fairness, equality, and justice. The insights provided into liberation psychology's concepts of critical consciousness, empowerment, and social justice action can enhance the well‑being of individuals and improve lives.
