Transformative service research methodologies for vulnerable participants

Understanding vulnerable consumers when conducting Transformative Service Research (TSR) is essential but these consumers and their contexts are often complex and difficult to research. Despite a movement towards TSR methodologies suitable for studying vulnerable participants and their contexts, a comprehensive framework that can guide service researchers is lacking. The purpose of this paper is to investigate appropriate methods, procedures, and protocols that permit researching a wide range of vulnerable groups and exposures to vulnerable situations in TSR. This is undertaken via a review of the literature and the authors' reflections of their experiences with researching vulnerability in various configurations (e.g., disasters, refugees, healthcare, disability, and older people). Through an iterative process of personal case reflections and group discussions blended with extant literature, patterns and insights regarding appropriate research protocols, techniques, processes, and sampling are identified. These insights contribute to the development of a comprehensive TSR framework in five research method areas including 1) consideration of the context, researcher, support persons and participants, 2) recruitment considerations relating to sampling, 3) recruitment considerations in terms of ethics and set-up, 4) data collection considerations relating to research protocol and set-up, and 5) data collection considerations. The framework can guide both academics and practitioners to enhance research outcomes for both participants and researchers.
