About us Glossary User involvement Definition of user involvement (based on Wallcraft 2003) The term ‘user involvement’ is used in this report to mean the various ways in which mental health service users/survivors are helping to change mental health and social services. This often works through service users/survivors becoming members of committees along with professionals and people from voluntary organisations, though it can include a number of other ways, such as conferences, discussion forums, open days, service users/survivors acting as paid consultants, or professionals visiting user/survivor groups.
