Young People Transitioning From Child and Adolescent to Adult Mental Health Services: A Qualitative Systematic Review

To critically synthesise the literature on the lived experience of young adults about their transition to adult mental health services including the perspectives of key people in their world: parents, carers and clinicians. Young people within child and adolescent mental health services are usually required to transition to adult mental health services at the age of 18, despite evidence showing cognitive and emotional development impacted by childhood trauma, illness and adverse life events. This qualitative systematic review searched relevant electronic databases, policy documents, grey literature and theses examining original qualitative peer-reviewed studies published from 2009 to 2022 in English. The process utilised the PRISMA guidelines and the quality of papers assessed by the JBI critical appraisal tool. Nine papers met the criteria for inclusion in the review. The results indicate that qualitative research listening to the voices of young people transitioning to adult mental health services is a rarity. Even fewer papers examine the perspectives of key people in their lives: this review has critically synthesised the literature on the lived experience of young adults about their transition to adult mental health services including the perspectives of key people in their world: parents, carers and clinicians. The main themes identified include: age 18 is not a helpful trigger to transition; young people want more individualised planning; parents want more involvement and clinicians open up about a challenging nexus with adult mental health services.
