Authentic public and patient involvement with Deaf sign language users: It is not just about language access

This article concerns Public and Patient Involvement practice with Deaf people who are sign language users. It draws on the experience of public and patient involvement in a project concerning Deaf people's lived experience of dementia and focusses on: (i) creating the conditions of trust in circumstances of unrecorded knowledge; (ii) being a community insider as a necessary but not sufficient condition without public and patient involvement and (iii) community consultation as influencing positive public and patient involvement practice. It sets out a series of recommendations for authentic public and patient involvement practice with Deaf sign language users linked to each of these themes before considering more generally barriers to Deaf people's involvement in public and patient involvement in health and social care research.
