This is the first book to examine trauma research in the context of sport, exercise, and health. It outlines evidence-based, trauma-informed research practices, which qualitative researchers can use when conducting trauma research to prevent causing further harm to participants while maintaining a strengths-based approach. Featuring the trauma research of leading qualitative sport, exercise, and health researchers from around the world, each chapter showcases the contributors’ trauma research and participant context, followed by the ‘what, why, and how’ of trauma-informed research practices that were implemented. This book includes work from a wide range of contexts, including gender-based violence in sport and coaching, abuse in sport, the aftermath of abuse and violence, physical activity after spinal cord injury, trauma and limb amputation, trauma and homelessness, trauma and autistic adults, and sport for care-experienced youth. It provides researchers interested in working with populations affected by trauma with a qualitative research resource to build on, and highlights new directions in conducting trauma-informed research. This is important reading for any researcher with an interest in trauma not only in sport, exercise, and health research but also in qualitative research contexts more broadly. It is a valuable resource for anyone working in athlete welfare, sport and exercise psychology, youth sport, sport development, physical activity and health, disability, gender, safeguarding, or social work.
