Chronotherapy for Depressive Episodes

Официальное название

Chronotherapy for Patients With a Depressive Episode in a Public Mental Health Care Clinic in Norway: A Randomized Controlled Trial

Обзор

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.

Вмешательства

• Поведенческое Chronotherapy
  Chronotherapy involves three different interventions. Sleep deprivation/wake therapy will be conducted for 34 hours. To assist wake and to ensure that the participants adhere to the sleep deprivation, outpatients will be admitted to a one-night stay at the inpatient ward that is connected to the outpatient clinic at Nidaros DPS. Patients already admitted to inpatient treatment will be temporary transferred to the ward selected to oversee the sleep deprivation. Upon discharge, participants are en
• Поведенческое Treatment as usual
  Participants allocated to receive TAU alone, will receive standard treatment for a depressive episode in the outpatient or the inpatient clinic. This study will not give restrictions or guidelines on how this treatment should be performed. The TAU-group will receive the treatment the responsible therapist considers and evaluate best fitting in the situation. Typical interventions administered in therapy for a depressive episode includes medication, cognitive behavioral therapy, and other psychot
