Providing effective sport psychology services requires practitioners to conceptualize the unique issues and concerns of each individual athlete. However, collecting information on the athlete, understanding the athlete’s issues and needs, and determining how to best assist the athlete can be a complex process.

Two case examples are provided to illustrate the case formulation process.
