Abstract
Nearly 2 million mild traumatic brain injuries occur annually and cognitive impairment is strongly associated with poor neurobehavioral performance. Identifying variables that influence the development of cognitive impairment could lead to the development of therapies designed to improve cognitive performance in at-risk populations. The theoretical framework used suggests that neurological factors, physical factors, psychological factors, objective cognitive deficits, and subjective cognitive deficits influence cognitive impairment. Specific aims were: (1) test the correlational relationships among the independent variables (neurological factors, physical factors, psychological factors, objective cognitive deficits, subjective cognitive deficits) and the dependent variable, cognitive impairment; and (2) develop a model that best describes the factors contributing to cognitive impairment. Multiple correlation and regression analyses were used to determine the relationships between each of the independent variables and the dependent variable.
