Background: The recent Australian National Agenda for Eating Disorders highlights the role technology can play in improving accessibility and service development through web-based prevention, early access pathways, self-help, and recovery assistance. However, engagement with the eating disorders community to co-design, build, and evaluate these much-needed technology solutions through participatory design processes has been lacking and, until recently, underresourced. Objective: This study aims to customize and configure a technology solution for a nontraditional (web-based, phone, email) mental health service that provides support for eating disorders and body image issues through the use of participatory design processes. Methods: Participants were recruited chiefly through the Butterfly National Helpline 1800 ED HOPE (Butterfly's National Helpline), an Australian-wide helpline supporting anyone concerned by an eating disorder or body image issue. Participants included individuals with lived experience of eating disorders and body image issues, their supportive others (such as family, health professionals, support workers), and staff of the Butterfly Foundation. Participants took part in participatory design workshops, running up to four hours, which were held nationally in urban and regional locations. The workshop agenda followed an established process of discovery, evaluation, and prototyping. Workshop activities included open and prompted discussion, reviewing working prototypes, creating descriptive artifacts, and developing user journeys. Workshop artifacts were used in a knowledge translation process, which identified key learnings to inform user journeys, user personas, and the customization and configuration of the InnoWell Platform for Butterfly's National Helpline. Further, key themes were identified using thematic techniques and coded in NVivo 12 software. Results: Six participatory design workshops were held, of which 45 participants took part. Participants highlighted that there is a critical need to address some of the barriers to care, particularly in regional and rural areas. The workshops highlighted seven overarching qualitative themes: identified barriers to care within the current system; need for people to be able to access the right care anywhere, anytime; recommendations for the technological solution (ie, InnoWell Platform features and functionality); need for communication, coordination, and integration of a technological solution embedded in Butterfly's National Helpline; need to consider engagement and tone within the technological solution; identified challenges and areas to consider when implementing a technological solution in the Helpline; and potential outcomes of the technological solution embedded in the Helpline relating to system and service reform. Ultimately, this technology solution should ensure that the right care is provided to individuals the first time. Conclusions: Our findings highlight the value of actively engaging stakeholders in participatory design processes for the customization and configuration of new technologies. End users can highlight the critical areas of need, which can be used as a catalyst for reform through the implementation of these technologies in nontraditional services.
