We sought to generate recommendations for the tennis community regarding the provision of mental healthcare and the promotion of mental wellness among elite tennis athletes, including junior tennis athletes.

Recommendations were generated using a multimethod approach that included an in-person summit held during the 2022 US Open Tennis Championships in New York, New York, USA, and an asynchronous Delphi consensus process. Participants (n=83) were purposively selected to ensure diverse representation from all seven governing bodies of tennis and the broader tennis ecosystem, including: current and former elite adult and junior players, coaches, sport administrators, parents, physiotherapists, athletic trainers, physicians (sports medicine, psychiatry, neurology), other licensed mental health providers, epidemiologists and other academic subject matter experts. The summit included expert presentations and cross-organisation group discussion, which were used to generate provisional consensus statements. Statements were rated anonymously and refined iteratively based on synthesis of open-ended feedback until predetermined numeric thresholds were reached. The summit also included discussion of implementation challenges and priorities. As a result of this process, 2 foundational principles and 25 actionable recommendations were adopted, covering 5 domains: (1) standards of care, (2) education, (3) media and social media, (4) safeguarding and (5) research. The foundational principles emphasised that mental health must be prioritised by tennis governing bodies and that these bodies should collaborate across the tennis ecosystem. This output is a starting point for coordinated mental health efforts in tennis. More broadly, this pragmatic process is a replicable model for crossorganisational collaboration in other high-performance sports
