Abstract

Background Skin conditions carry a substantial psychological burden, yet the biomedical model of care remains prominent in dermatology and psychological support for patients is lacking. Digital technology can support self-management. This thesis aimed to co-develop a complex digital behaviour change intervention (DBCI) for adults with skin conditions, with patient input. Methods Mixed methods research focused on intervention planning, which comprised of two phases. Phase 1 involved: (1) formation of a Patient and Public Involvement group; (2) a systematic review of digital psychological interventions in dermatology; (3) an online survey and group interview study to understand adults’ (≥ 18 years) experiences of self-management, existing support and the perceived acceptability of a DBCI called MiDerm. Phase 2 prioritised the design, development and build of MiDerm. Studies were informed by the Common-Sense Model of Self-Regulation and the Theoretical Framework of Acceptability. Intervention development followed the Person-Based Approach and was informed by the Behaviour Change Wheel. Results Existing digital interventions were mostly web-based, educational and condition-specific. They were potentially acceptable and effective, but evidence was limited and barriers were identified. Overall, 413 people across 30 countries representing 24 skin conditions participated. Results emphasised the impact of self-management and limitations and inadequacies associated with medical care and psychological, social and peer support. Psychological support was needed and the idea of a smartphone app including informational, emotional, behavioural and peer support was generally welcomed as an adjunct to current care. Respecting personal autonomy seemed imperative for overcoming potential barriers. Results informed intervention development. Conclusion ii Quality and interdisciplinary research to develop and test DBCIs with adults with skin conditions was needed. Research findings supported and informed the development of MiDerm. Next is to evaluate, optimise and implement MiDerm for use among the target group
