Adjunctive Bright Light Therapy for Patients With Depression at Different Time Period: A Randomized Double-Blind, Placebo-Controlled Trial
The study would enroll depressed adolescents and adults with bipolar I or II disorder or major depressive disorder who are receiving stable psychiatric medication (excluding patients with hypomania or mania, mixed symptoms, or rapid cycling). Participants would be randomly assigned to treatment with either 1,0000-lux bright white light therapy in the morning or 1,0000-lux bright white light therapy in the afternoon, or <100-lux dim red placebo light therapy in the afternoon (N=59 for each group). Participants would be treated for 6 weeks. Symptoms would be assessed every two weeks with the 24-items Hamilton Depression Scale, the Young Mania Rating Scale, and the Pittsburgh Sleep Quality Index; salivary melatonin and cortisol concentrations will be also measured.

Secondary | manic/hypomanic conversion rate | The Young Mania Rating Scale (YMRS) is used to assess manic/hypomanic symptoms and their severity; its measured time range is within the past week. The higher the score, the more severe the symptom. If the total score is greater than or equal to 20, manic episode is considered; if the total score is less than 6, it means there is no manic/hypomanic symptoms. | week 2; week 4; week 6 | |

Secondary | sleep quality | Pittsburgh Sleep Quality Index (PSQI) is used to evaluate sleep quality for last month. It's made of 7 items; every item is scored 1-4 point.
