This research is an exploration of the experiences of sport parents whose children have left the athlete role, and how that desocialization has been experienced by the parents. Numerous studies have examined the transition experiences of athletes themselves, but little attention has been given to how parents, many of whom have very strong identities tied into the sport parent role, cope with leaving that role either voluntarily or involuntarily. In the first phase of this research investigating the desocialization experience of sport parents, the researchers are conducting in-depth, semi-structured interviews with participants, which will later inform the creation of a sport parent desocialization measure.
