Existing literature reveals shortcomings in reporting on digital health interventions (DHIs) development and evaluation, resulting in limited traceability and hampered knowledge growth. Despite existing health research reporting guidelines, a specific guideline for the participatory development and evaluation of DHIs is lacking. This study aimed to develop a consensus-based reporting guideline to increase the transparency and comparability of both the participatory development and evaluation of DHIs. Following the methodology recommended by the EQUATOR Network and Mohers et al., a web-based Delphi Study comprising three rounds (two surveys; one workshop) was conducted. An international panel of 66 experts from 23 countries agreed on 68 items for the final reporting guideline, derived from existing reporting guidelines and refined through expert consultation. The final consensus-based reporting guideline ParDE-DHI addresses a significant gap in the systematic reporting of participatory development and evaluation of DHIs. Tailored to the unique challenges of participatory design and research, it enhances the credibility and comparability of study designs and results. This is a crucial step towards promoting best practices and advancing methodological rigor in the field. International and interdisciplinary panel input ensures adaptability and relevance across digital health contexts, ultimately fostering improved participation and knowledge sharing within the research community.AI机翻:
