Virtual Resilience, Real Consensus: Methodological Framework for a VR-Based Resilience Intervention Using a Modified Delphi Approach.

This concept paper outlines the methodological design and rationale behind a modified Delphi study conducted within the Horizon 2020 project XR2esilience, which aims to develop a virtual reality (VR)-based resilience training for nurses. The paper focuses on the consensus-oriented Delphi approach to support the early-phase co-development of digital health interventions. Experts from nursing, psychology, education, and VR development participated in a multi-round process to prioritize content areas, implementation strategies, and contextual considerations. The Delphi method was adapted to the needs of interdisciplinary collaboration and stakeholder integration in digital intervention design. As a concept paper, it outlines methodological foundations and consensus processes, offering guidance for similar initiatives seeking to combine technological innovation with participatory, consensus-driven development in healthcare.
