Empowering participation is relevant to many prevention programs. Yet many attempts at empowerment proceed without any clear understanding of the nature of empowerment or the practical requirements of an empowering process. This paper draws on the extensive program-development research for two Canadian prevention projects for disadvantaged children and families: the Parent Mutual Aid Organizations in Child Welfare Project and the Better Beginnings. Better Futures Prevention Project. The lessons learned in these projects about fostering empowering participation are summarized. The paper emphasizes the necessity to respect the demanding and complex requirements of successful empowering participation as well as the need to balance empowering participation with other priorities in prevention programs and projects.
