Transdisciplinarity research is issue-driven, addressing contemporary social questions from a range of critical theoretical perspectives unhampered by the theoretical and methological restrictions of traditional disciplinary boundaries. In this brief, informative guide, Patricia Leavy shows how a transdisciplinary approach can produce more effective results for qualitative researchers hoping to ameliorate social problems and foster social justice. She explains its relationship to multi-disciplinary and interdisciplinary research and its value in community-based and arts-based research projects. Providing the key principles and methods needed to conduct a transdisciplinary study, Leavy also offers numerous examples from multiple research sectors to show its effectiveness. Ideal as a brief introductory text for students engaged in this style of research.
