Co-production in mental health

This usually means working together with people with lived experience of mental health difficutlies throughout the research process - from prioritisation and design to dissemination. Her latest work examines the impact of COVID-19 lockdown on the mental health and coping strategies of young people which is co-produced with young people with experience of mental health difficulties.
