Child abuse in sports is a significant threat to the well-being of young athletes. The aim of this study was to create in-depth knowledge of children’s perspectives and relational situations regarding the manifestation and effects of emotional abuse towards athletes in children’s sports. Based on interviews with 15 children aged 12–18 and five coaches, five themes of emotionally abusive interactions were identified: (a) scolding by coaches; (b) negative criticism from coaches and children; (c) expression of aggression and disappointment by coaches; (d) teasing and joking by children; and (e) denial of attention and support from coaches. These interactions lead to emotionally harmful effects for some of the children, which were not always recognized by coaches and were sometimes downplayed. The findings have implications for identifying situations and behaviours that may constitute emotional abuse in children’s sports, paving the way for proactive measures aimed at preventing emotional abuse.
