Abstract
BACKGROUND: Adolescents with type 1 diabetes face unique challenges in adapting to closed-loop technology. Positive psychology interventions may aid in promoting psychological adjustment, enhancing well-being and supporting the effective use of this technology. AIM: This study describes the development, content and evaluation of a positive psychology intervention, the Flourish Diabetes Programme, to facilitate adjustment to closed-loop technology among adolescents with type 1 diabetes. SETTING: The Flourish Diabetes Programme is an online, interactive intervention aimed at adolescents living with type 1 diabetes who use closed-loop technology. METHODS: The development of the programme was informed by qualitative research with adolescents, qualitative document analysis and the design and development model. The Delphi method was used to evaluate the intervention, where 11 experts provided feedback to refine and enhance the programme. RESULTS: Feedback from the Delphi panel informed the refinement and finalisation of the Flourish Diabetes Programme, contributing to an evidence-based and user-centred intervention. CONCLUSION: The Flourish Diabetes Programme is a tailored online resource designed to support adolescents in adapting to closed-loop technology. Insights from the Delphi panel helped shape the programme into a practical tool for promoting positive adjustment. CONTRIBUTION: This intervention is the first step in developing effective, evidence-based resources to help adolescents with type 1 diabetes manage new medical technologies, specifically closed-loop systems, using positive psychological principles.
