Participatory Action Research (PAR) is an approach to enquiry which has been used since the 1940s. It involves researchers and participants working together to understand a problematic situation and change it for the better. There are many definitions of the approach, which share some common elements. PAR focuses on social change that promotes democracy and challenges inequality; is context-specific, often targeted on the needs of a particular group; is an iterative cycle of research, action and reflection; and often seeks to ‘liberate’ participants to have a greater awareness of their situation in order to take action. PAR uses a range of different methods, both qualitative and quantitative.
