This study will evaluate the efficacy of a newly developed serious game, SCI HARD, to enhance self-management skills, self-reported health behaviors, and quality of life among adolescents and young adults with spinal cord injury and disease (SCI/D). SCI HARD was designed by the project PI, Dr. Meade, in collaboration with the UM3D (University of Michigan three dimensional) Lab between 2010 and 2013 with funding from a NIDRR (National Institute on Disability and Rehabilitation Research) Field Initiated Development Grant to assist persons with SCI develop and apply the necessary skills to keep their bodies healthy while managing the many aspects of SCI care. The study makes a unique contribution to rehabilitation by emphasizing the concepts of personal responsibility and control over one's health and life as a whole. By selecting an innovative approach for program implementation, we also attempt to address the high cost of care delivery and lack of health care access to underserved populations with SCI/D living across the United States (US).
