Book excerpt: Community-based participatory research (CBPR) presents unique ethical and practical challenges, particularly for graduate students. This volume explores the nuanced experience of conducting CBPR as a PhD student. It explains the essential roles of developing trust and community relationships, the uncertainty in timing and direction of CBPR projects that give decision-making authority to communities, and the politics and ethical quandaries when deploying CBPR approaches—both for communities and for graduate students. The Community-Based PhD brings together the experiences of PhD students from a range of disciplines discussing CBPR in the arts, humanities, social sciences, public health, and STEM fields. They write honestly about what worked, what didn’t, and what they learned. Essays address the impacts of extended research time frames, why specialized skill sets may be needed to develop community-driven research priorities, the value of effective relationship building with community partners, and how to understand and navigate inter- and intra-community politics. This volume provides frameworks for approaching dilemmas that graduate student CBPR researchers face. They discuss their mistakes, document their successes, and also share painful failures and missteps, viewing them as valuable opportunities for learning and pushing the field forward. Several chapters are co-authored by community partners and provide insights from diverse community perspectives. The Community-Based PhD is essential reading for graduate students, scholars, and the faculty who mentor them in a way that truly crosses disciplinary boundaries. Contributors: Anna S.
