Although research has begun to examine sleep quality within the traumatic brain injury (TBI) population, most of the studies found in the research literature utilize subjective, self-report measures that can be problematic in terms of response accuracy when used with populations that have known cognitive deficits (Baños, LaGory, Sawrie, Faught, Knowlton, Prasad, Kuzniecky and Martin, 2004). Because TBI often results in a diminished capacity for self-reflective awareness, obtaining reliable sleep-related information is difficult to do through surveys alone (Fleming, Strong, Ashton, 1996; Vanderploeg, Belanger, Duchnick, and Curtiss, 2007).
