A review of the literature examining the effects of athletic injury on persons have suggested a deleterious effect. Specifically, results indicated that following traumatic injury, athletes suffer a diminution of affect and feelings of self-worth. Because studies published in this area have been post-injury in design, the present study was fashioned to examine changes from baseline values in the self-concept of university varsity football players following a disabling injury. There were 29 athletes in the subject pool. Sixteen subjects were severely injured during the season. Measures were taken on the first day of fall practice and at the end of the season. Injured athletes were assessed each week while they were unable to participate in practice. Analysis revealed a significant decrease in generalized self-concept following athletic injury (p < 0.001) which persisted through the course of treatment. Suggestions for continued research and treatment are proffered.
