This article provides an overview of several core theoretical and practical aspects of participatory action research (PAR). An effort is made to define PAR and the types of work that fall under that rubric. Historical underpinnings, roles of the individuals involved, contexts, methods, and the challenges and benefits of this mode of inquiry are discussed. The authors argue that the approach and mindset of the researcher, referred to here as a type of "attitude," are key in the development of a successful and genuine participatory process. The authors situate PAR methodology within psychology and, more specifically, propose it as an approach to knowing that has the potential to make significant contributions in areas relevant to counseling psychology.
