About this study

Evidence-based treatments for depression, such as antidepressive medication, usually have a latency of 4 to 6 weeks before they achieve a therapeutic effect. Chronotherapy is a group of non-pharmacological interventions that presumably act on the circadian system to achieve a rapid-onset clinical effect and better long-term effects and has been shown efficient to improve depressive symptoms. Interventions include sleep deprivation, sleep-phase advancement and stabilization, and light therapy. There are few studies testing the effectiveness of combining these three chronotherapeutic techniques in the initial phase of treatment of depression in a mental health care clinic. The investigators aim to test the effects and safety of chronotherapy in addition to TAU compared to TAU alone, with the primary outcome being self-reported depressive symptoms at 1 week following randomization. The study is a randomized controlled trial with 76 patients with a depressive episode who initiate treatment at Nidaros DPS, St. Olavs University Hospital. Participants will be allocated 1:1 to either chronotherapy + treatment as usual (TAU) or to TAU alone.
