The Centre for Social Justice and Community Action (CSJCA) has a particular interest in the ethical issues that arise in research that is community-based and participatory. Ethics relates to doing good and harm; how people are treated; and who benefits from research. In Community Based Participatory Research (CBPR) there may be particular questions about how to share power and resources, and create mutual respect, for example: Who owns this information? Are we being fair? Is this an equal partnership? These web pages focus on CSJCA’s work on ethics, including a guide to ethical principles and practice, case examples, films, articles and a range of other downloadable resources for use by researchers and students based in communities and universities, and anyone interested in planning or evaluating CBPR.
