Athlete mental health, though long present within research and practice, has recently become a central topic area within the sport and exercise psychology field. The International Society of Sport Psychology has been at the forefront of these discussions, evidenced by a foundational position stand in 2018 and subsequent consensus statements derived from international think tanks. Within this position stand, contributors from the international community spanning five continents collaborated to present key, updated ideas and emerging concepts relating to clinical understandings of athlete mental health, trends in athlete mental health status, the role of the sport environment, mental health in relation to athlete careers, the global treatment of athlete mental health, cultural considerations in relation to understanding this topic, and nine synthesising postulates. © 2024 International Society of Sport Psychology.
