This study utilized Self-Determination Theory to examine how an athletic trainer’s communication impacts collegiate athlete’s motivation to adhere to rehabilitation treatment during a sport related injury. Patient-centered communication (PCC) has been commonly explored within standard clinical health settings but has yet to be prioritized within care administered by athletic trainers among collegiate sports. Through the consideration of how athletes perceive the care given to them by their athletic trainer, possible solutions to aid in improving athletes’ health outcomes are suggested. Findings reveal that patient-centered communication is positively associated with self-efficacy and intrinsic motivation; each of these concepts was also associated with an athlete’s adherence to a prescribed treatment plan. These findings can inform how athletic trainers engage with athletes at various stages of the recovery process.
