Kelly Rohan, University of Vermont (IMAGE) University of Vermont Caption Talk outshines light in keeping the winter blues at bay, University of Vermont researcher Kelly Rohan found in a study to be published in the American Journal of Psychiatry. Two winters after the initial treatment, 46 percent of research subjects given light therapy reported a recurrence of depression compared with 27 percent of those who were administered CBT. Depressive symptoms were also more severe for those who received light therapy. Rohan is pictured with a light box used in light therapy.
