Blackpool is one of the most socio-economically deprived towns in England, with higher levels of poverty, physical and mental health issues, self-harm and suicide rates, higher proportion of children and young people (CYP) in care system, poorer educational outcomes, and lower life expectancy compared to the national average. However, Blackpool also hosts an inspiring community and organisations that are committed to improving lives of CYP and helping them reach their developmental potential. As part of the initiatives to promote healthy development in Blackpool’s CYP, this project aims to improve mental health literacy (MHL) in parents, who are best placed to support CYP facing mental health difficulties. MHL refers to the knowledge, attitudes, and beliefs regarding mental health disorders that aid their recognition, prevention, and treatment. The current project focuses on exploring the experiences of CYP, parents and professionals supporting them, regarding the role of parental MHL in supporting CYP mental health. The scope of the project has been determined by the NIHR Research Ready Communities (RRC) pilot, involving a group of young people and representatives of third sector community organisations (i.e., co-facilitators) living and working in Blackpool. For this project, the team will further expand by recruiting academic researchers, as well as parents and mental health professionals as co-researchers with relevant experience. The team will collect data via interviews with CYP, parents, and mental health professionals to explore their experiences and perspectives regarding the role of parental MHL in supporting CYP mental health. The findings will be used to co-produce an intervention to improve parental MHL through increased knowledge of risk and protective factors for CYP mental health, help-seeking options and treatments available, and self-help strategies for milder problems, as well as improved attitudes and skills for early recognition of mental health issues and help-seeking behaviour.
