The transition from high school to college in American culture signifies a profound life experience marked by ecological and developmental shifts. This period exposes college students, particularly first-year students, to heightened susceptibility to mental illness, with alarming statistics indicating that 1 in 3 will experience symptoms associated with mental health disorders. Among these students, athletes face an additional layer of challenges, navigating both academic and sports-related stressors, including rigorous training schedules, athletic performance pressures, and injury recovery. With approximately 480,000 college students participating in the US National Collegiate Athletic Association (NCAA), addressing the specific needs of student-athletes during this arduous transition becomes crucial. The current research landscape reveals limited studies on the adjustment process of first-year student-athletes, highlighting specific gaps related to their unique challenges and potential support programs. Recognizing the identified necessity for psychological support among freshman college athletes, this Doctoral Project adopted a Demonstration format to introduce a concise group therapy curriculum tailored for this demographic. The curriculum aims to provide flexible delivery throughout the first semester, with the goal of facilitating a smoother transition to college for first-year athletes and fostering psychological well-being during this critical developmental period. This curriculum was reviewed by expert consultants, resulting in improvements to the structure, clarity, and adaptation to each student-athlete group. The finalized product contains three modules intended for clinical application for freshman student-athletes in college counseling settings, particularly students identified as struggling with their acclimation to the college environment.
