Service users are increasingly involved in health and social care research, both in terms of representation of their voices, being involved in action research projects and in leading research themselves. This is reflected in government policy to consult service users in reviewing policies and in shaping health and social care sevices. This edited collection provides examples of research methods with service users along a continuum of involvement as participants through to service user-led research. Chapters are written collaboratively with users themselves providing a diverse but valuable range of voices and good practice case studies.
