Poor sleep in medicated patients with remitted depressive disorder: A naturalistic study

Objectives: Depression with partial remission and residual symptoms following treatments is common. Elucidating the problems remaining in the remitted patients would help optimize treatment. In this study, we intended to study remission rate and related factors as well as their unresolved problems in patients with treated depressive disorder. Methods: We included 65 medicated patients with depression for 6–12 months. We also chose 65 healthy persons as a control group. The study participants completed Beck Depression Inventory (BDI), checklists of side effects, Sheehan Disability Scale, World Health Organization Quality-of-Life-brief version, and Pittsburgh Sleep Quality Index (PSQI). Remission was defined as a BDI score of ≤ 15. Results: We found that the PSQI score was still higher in the remission group than the control group. Conclusion: Sleep problems, which may still be a commonly unresolved problem in medicated patients with depression, should be noticed by clinicians
