Measure
Cognitive-Behavioral Therapy for Insomnia
6-week manualized treatment designed to improve symptoms of chronic insomnia. Cognitive-Behavioral Therapy for Insomnia: Intervention includes strategies designed to improve sleep such as: sleep restriction, stimulus-control techniques, sleep hygiene education, and relaxation training.
Sleep Education
6-week manualized treatment designed to provide information regarding traumatic brain injury and its relationship to sleep disturbance, which incorporates training in sleep hygiene to help improve nighttime sleep and daytime functioning. Sleep Education: Intervention includes sleep hygiene education and education regarding the impact of TBI on sleep.

Change in cognitive functioning will be evaluated through standardized assessments of attention and processing speed. The tasks that will be administered include: the Wechsler Adult Intelligence Scale Fourth Edition (WAIS-IV) Digit Symbol and Symbol Search to measure attention and processing speed. WAIS-IV raw minimum value score=45; maximum score=155. Scaled score used: minimum score = 1; maximum score = 19. Higher score equals a better outcome.

Change in cognitive functioning will be evaluated through standardized assessments of verbal learning and memory. The Hopkins Verbal Learning Test-Revised (HVLT-R) was used to measure learning and memory, and was measured by "Total Recall" score and "Delayed Recall" score. HVLT Total Recall raw scores minimum value=0; maximum value=36. Measures scored on a T-Score; minimum t-score score:0, maximum t-score \>80. Higher t-scores indicate better outcome. HVLT delayed recall minimum raw score value=0; maximum value=12. Measures scored on a T-Score; maximum t-score value: 60, minimum =0. Higher t-scores indicate better outcome. Population mean and standard deviation calculated based on age. Mean age of the population was 36 years = total recall population t score mean: 28.04, SD: 4.43. Delayed recall population t score mean: 9.92, SD: 2.04.

Change in cognitive functioning will be evaluated through standardized assessments of executive functioning. The Delis-Kaplan Executive Function Scale (D-KEFS) Trials and Color-Word Tasks was used to measure executive functioning, as measured by Color-Word Inhibition, Color-Word Switching Inhibition, and Trails. Scored using a scaled-score (minimum=1, maximum=19 for all measures). Higher scores indicate better outcome.
