21. Methodological Disconnect

22. Transdisciplinary Research  Multidisciplinary Research researchers from different fields work independently or sequentially, each from his or her own disciplinary perspective, to address a particular research topic  Interdisciplinary Research entails greater sharing of information and closer coordination among researchers from various fields than occurs in multidisciplinary projects, yet the participants remain anchored in their respective disciplinary models and methodologies  Transdisciplinary Research researchers work together to develop a shared conceptual framework that integrates and extends discipline-based concepts, theories, and methods to address a common research topic. Transdisciplinary research collaborations are intended to achieve the highest levels of intellectual integration across multiple fields and yield shared conceptual formulations that move beyond the disciplinary perspectives represented by team members. Stokols D. Toward a science of transdisciplinary action research. Am J Community Psychol. 2006 Sep;38(1-2):63

23. Community-Based Participatory Research (CBPR)  A collaborative process that equitably involves all partners in the research process and recognizes the unique strengths that each brings. CBPR begins with a research topic of importance to the community with the aim of combining knowledge and action for social change to improve community health and eliminate health disparities Minkler M, Wallerstein N, eds. Community Based Participatory Research for Health. San Francisco, Calif: Jossey-Bass Publishers; 2003
