Official title
Comparison of N-of-1 Trials of Light Therapy for Depressive Symptoms in Cancer Survivors
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study compares the effect of two N-of-1 trials on study compliance with an N-of-1 protocol and on satisfaction with participation in an N-of-1 trial. Using within-person analyses, the study also compares the effect of different types of light therapy on mood, fatigue, sleep, physical activity, and side effects within a mild to moderately depressed cancer survivor population. Ten participants will be randomized to the bright white versus dim red light therapy N-of-1 trial, while the remaining 5 participants will be randomized to a dim white versus dim red light comparator N-of-1 trial.
