Outcomes
Primary Outcome Measures
Cognitive Functioning (Neuropsychological Tests)
Global composite z-score from baseline to 8 weeks after the intervention based on the HVLT-R; BVMT-R; Psychomotor vigilance task; Trail-making tests A and B; WAIS-IV Coding, Digit Span, Block Design; D-KEFS Color-Word Inhibition, Verbal Fluency; Conners Continuous Performance Test III.
Raw scores at baseline of tests within single domains were averaged and then standardized to z-scores. The mean of the z-scores was calculated, and then this composite z-score was standardized to z-scores. Follow up intervention z-scores were calculated based on differences between raw scores at baseline and raw scores at follow-up time points and divided by the standard deviation of the baseline domain z-score) within each domain, and then averaged to create follow up global composite scores.
A z-score below 0 indicated poorer performance than at baseline and a z-score above 0 indicated better performance than at baseline.
Secondary Outcome Measures
Circadian Activity Rhythms (Actigraphy)
F statistic from actigraphy was assessed as a measure of circadian activity rhythm robustness.
Sleep Quality (Pittsburgh Sleep Quality Index)
The Pittsburgh Sleep Quality Index consists of 19 self-rated items used to calculate sleep quality
Fatigue (FACIT-fatigue)
This is a 13-item measure of fatigue.
Depressed Mood (CESD)
The Center for Epidemiological Studies Depression Scale (CES-D) is a 20-item self-report instrument that measures symptoms of depressed mood over the past week.
Neurobehavioral Functioning (Frontal Systems Behavioral Scale)
Total raw score for entire scale (minimum = 46, maximum = 230) with a higher score indicating greater neurobehavioral symptomatology.
Quality of Life (FACT-BMT)
This 50-item scale is a commonly used and well-validated measure of the functional status of cancer patients who have undergone BMT (SCT).
Interleukin-6
Serum cytokine IL-6 in pg/mL
Pro-inflammatory Cytokine - TNF Alpha
Serum cytokine TNF-α in pg/mL
C-Reactive Protein
C-reactive protein in mg/L
Self-reported Cognitive Function (Patient Assessment of Own Functioning Inventory)
The 33-item Patient Assessment of Own Functioning Inventory (PAOFI) is a reliable and valid measure of perceptions of cognitive functioning (Bell et al., 2013; Chelune et al., 1986). Using a Likert scale from 1 (Almost Always) to 6 (Almost Never), ratings of 1-3 were scored "1" indicating impairment, and ratings from 4 to 6 were scored "0" indicating no impairment. Total impairment was calculated by summing the number of impaired items.

5. Study Description
Brief Summary
Cognitive impairment (such as memory problems) due to cancer and its treatment can interfere with quality of life and can linger long after treatment has ended, yet research examining cognitive rehabilitation approaches has produced limited clinical benefit. The proposed study will provide information about systematic light exposure for the treatment of cognitive impairment in hematopoietic stem cell transplant (HSCT) survivors and will investigate how it works. This study would facilitate the development of this potential treatment, giving health care providers and cancer survivors a much-needed tool to help with cancer-related cognitive impairment.
