Individuals around the globe engage in physical activity for personal interest or general health and fitness. Although participation in regular physical activity is important for general health it also brings with it the risk of injury. Ankle sprains, anterior cruciate ligament tears, and concussions are just a few of the injuries sustained by physically active individuals with long-term implications. With the number of physically active individuals on the rise, sports-related injuries are of growing concern.

Health-related quality of life (HRQOL) is a personal evaluation of everyday functioning and well-being. A variety of injuries and health conditions associated with physical activity have been linked to HRQOL deficits. Despite these findings, the literature has yet to determine the influence of injury in physically active populations on the multidimensional profile of HRQOL.

The purpose of this dissertation was to explore the influence of injury history of HRQOL in physically active individuals. The purpose of the literature review was to systematically summarize the extent to which HRQOL deficits are present in individuals with chronic ankle instability (CAI) and adolescent and collegiate athletes. The purposes of these studies were to explore HRQOL differences between individuals with and without CAI, to determine if clinical and laboratory measure of function can predict HRQOL scores in individuals with CAI, and to examine the scale structure of the Disablement in the Physically Active Scale (DAP), as well as, the influence of injury and participation on HRQOL in collegiate athletes.

The results of the systematic reviews suggest that CAI and sports-related injuries are associated with decreased HRQOL. In Project I, individuals with CIA displayed decreased HRQOL based on generic, region-specific, and dimension—specific patient-reported outcomes. In Project II, a combination of mechanical and functional impairments accounted for 17-36% of the variance associated with patient-outcomes related to physical function and fear. In Project III, collegiate athletes exhibited HRQOL deficits based on injury history, participation status, and time since last injury. Additionally, physical and mental subscales were identified within the existing structure of the DPA. The results of these studies expose the overlap between physical impairment and patient-reported outcomes and confirm that physically active individuals exhibit HRQOL deficits following injury. As a result, patient-reported outcomes should be used in clinical practice to treat the entire spectrum of disability.
