Because of its epidemic proportion and the well-evidenced negative consequences, abuse is a major public health problem worldwide. Unfortunately, sports is not immune to abuse. This project focuses on harassment and abuse perpetrated by youth sports coaches. Relying on Self-Determination Theory, this project aims to examine whether a pressuring and controlling coaching style forms a gateway towards athlete harassment and abuse. While coaches are often the main and sole focus of research, coaches are not operating in isolation. In the current project, we add an innovative organizational perspective to the predominant psychological approach of athlete harassment and abuse in sports. Starting from normalization theory, we focus on the degree to which different stakeholders within the club normalize controlling coaching, and how this impacts athletes' harassment and abuse. Three complementary studies, including a highly unique and innovative longitudinal study covering two sport seasons as well as an in-depth action research approach in the club, are put forward.
