Key life transitions such as moving from school to college, or into the workforce can increase vulnerability.MethodA mixed-methods evaluation was conducted of a multi-component, mental health intervention in the East of England. The evaluation aimed to: (1) Assess the fidelity, dose, and reach of the intervention; (2) Understand the mechanisms of impact and how change was generated; (3) Explore the influence of context, including dynamic relationships between those involved in delivering and accepting support, settings, and service delivery models; and (4) Assess if the intervention offered good value for money. Semi-structured interviews were held with local public health staff (n = 3), and an intervention lead. A focus group was conducted with intervention leads (n = 3). Photo production interviews were held with young people (n = 10). Quantitative outcomes were explored through pre- and post- questionnaires (n = 34), and pre-post intervention assessment of young people’s wellbeing, and satisfaction with the intervention, using the DIALOG (n = 34) and Wellbeing star measures (n = 37). Value for money was assessed using commissioned, in-house cost data and qualitative insights.ResultsThe intervention demonstrated positive outcomes in life satisfaction and functional wellbeing for young people, with young people engaging across the intervention components (n = 82, CC Hubs, n = 74, WN, n = 53, BR). The most cost-effective components were Upskilling the Workforce and Wellbeing Navigator support. Third spaces, and creative methods, fostered engagement and acceptability among young people.ConclusionIntegrated, co-produced, and place-based approaches can support young people’s mental health needs during life transitions. Investment in local partnerships and youth-centred design is important.
