The field of clinical sport psychology is rapidly advancing in research, policy, and practice. Indeed, recent attention to athletes’ mental health has been fueled by courageous professional athletes who have publicly disclosed their struggles balancing the tension between optimum mental health and sport performance in high-pressure environments. Built upon the early success of sport performance interventions, practitioners of clinical sport psychology are now able to access sport-specific and psychometrically validated mental health assessments/screens, awareness programs, engagement interventions, and treatments developed in controlled clinical trials with athletes. These developments have assisted in answering the call from athletes, sport administrators, and athletes’ family members to improve athletes’ safety and overall mental wellness. In this chapter, we review scope of practice issues that are relevant to clinical and counseling sport psychologists including historical overtures, required qualifications and proficiencies, implementation settings, and clinical and administrative strategies and recommendations to assist practitioners in successfully navigating through multiple and complex systems.
