1. Home-based bright light therapy is a feasible adjunctive treatment with a highly tolerable adverse effect profile.
2. Home-based bright light therapy with gradual timing advance improves clinical outcome, with a quicker treatment effect, which is evident from a higher remission rate at week 2 of treatment and a higher cumulative remission rate for 5 months after treatment.
3. Adjunctive bright light therapy for patients with unipolar non-seasonal depression and eveningchronotype may be used in clinical practice to improve clinical outcomes.
