  1. What is the efficacy of CBT-D and CBT-D plus bright light therapy in reducing depression severity in adolescents with depression and eveningness?
  2. What are the effects of CBT-D and CBT-D plus bright light therapy on the subjective and objective sleep and circadian measures, as well as the quality of life, daytime symptoms, and functioning (e.g., sleepiness, fatigue)?
