User Experiences of a Self-Guided Dialectical Behaviour Therapy App for Eating Disorders: a Qualitative Study
摘要
Resilience is a self-guided dialectical behaviour therapy (DBT) app designed to support individuals with eating disorders (EDs). While effective in reducing ED symptoms, challenges with engagement and retention remain. This study explored user experiences with Resilience and examined factors influencing engagement within a 12-week randomised controlled trial. Semi-structured interviews were conducted with ten participants (White, highly educated women) with recurrent binge eating, and data were analysed using reflexive thematic analysis. App use varied, with six participants completing all five modules. Five key themes were identified: (1) motivation driven by long-standing struggles and unmet treatment needs; (2) varying patterns of use, from convenience-based to intentional engagement; (3) mixed responses to content, with some finding it reinforcing and others overwhelmed; (4) the role of notifications and intrinsic motivation in sustaining engagement; and (5) emotional awareness as both a catalyst for change and a challenge. Findings suggest that ED apps may benefit from offering flexible engagement options, tailored notifications, and structured guidance to reduce cognitive load. Personalised content that aligns with diverse user needs may enhance clinical impact. These insights offer practical recommendations to optimise Resilience and inform the development of future digital interventions for EDs.
