Athlete Mental Health and Performance Optimization: The Optimum Performance Program for Sports (TOPPS)introduces TOPPS, which provides structured protocols to assist with recruitment, engagement, screening, assessment and performance optimization. The book presents step-by-step instructional guidelines, real-world case examples, screening and assessment questionnaires, scoring instructions, intervention handouts and worksheets that complement intervention. TOPPS has demonstrated significantly improved relationships with teammates and coaches, decreased substance use and psychiatric symptoms, and decreased factors interfering with sport performance. These results have been sustained in follow-up and has been shown to have improved outcomes regardless of mental health diagnostic severity. The Book's first three chapters introduce performance optimization orientation, theories and evidence supporting TOPPS, general assessment and intervention approaches, psychometrically-validated measures and strategies used to address culture, methods of establishing a culture of optimization and requisite infrastructure within the respective system, and therapeutic style, techniques and implementation strategies. Remaining chapters show how to implement TOPPS.
