Book excerpt: User involvement is now official policy throughout the health and social care system. Does this mean that user involvement practices are unproblematic? Has it lost its radical edge as it has become an accepted part of service delivery, research and policy making? This important text offers a critical stocktake of the state of user involvement, comprising contributions from both user activists and leading academics. The contributors consider different contexts in which involvement is taking place, both in the groups involved and the activities they are engaged in, and includes different and sometimes conflicting perspectives on issues such as whether we should measure the impact of involvement. This valuable collection will be a crucial resource for students in health and social care and in social work, for researchers developing participative research practice, and for user activists seeking to learn how others have developed distinctive ways of challenging professional perspectives.
