The new edition of Community-Based Participatory Research for Health by Nina Wallerstein and colleagues is an extremely valuable resource for a wide variety of stakeholders interested in collaborative work to promote health equity. This updated collection succinctly delineates the theory, history, principles, and practices of community-based participatory research (CBPR) to help the reader understand CBPR as an approach, a philosophy, and an ethic. This updated edition will serve as a helpful resource for those interested in incorporating CBPR principles and approaches into their work. The chapters are authored by leaders and innovators in CBPR who provide insights, share experiences, and describe case studies that expand our ability to understand and envision the transformative power of CBPR in practice. The book is divided thematically into seven parts plus 13 appendices. Updates to this edition align with critical dialogues about positionality, privilege, and power in a way that encourages healthy self-reflection.
