Official title
The Sleep Clinic Outcome and Practice Study: The SUP-study
Overview
The goal of this clinical trial is to explore the outcome and practice treatment for sleep-wake disturbances in a Sleep Clinic. The main questions it aims to answer are: * What is the practice (timing and duration of treatment components) of sleep-wake disturbance treatment? * What is the treatment effect of sleep-wake disturbance treatment. Participants will receive treatment as usual by consultations with a trained psychiatrist or psychologist and will be asked to fill out self-reporting questionnaires and sleep diaries.
Detailed description
Background: Sleep-wake disturbances including insomnia disorder and sleep-wake rhythm disorders disables many aspects of life and is highly prevalent. As one of few treatment options for sleep-wake disturbances, the Sleep Clinic at St. Olavs Hospital offers clinical assessments and treatment for this patient group in Norway. Although the treatment of insomnia disorder is well-described and recommended, there is still a major subgroup that to not benefit from the treatment. Additionally, treatment and outcome of sleep-wake rhythm disorders is little described in clinical settings. A study of clinical practice and outcomes of the treatments in the Sleep Clinic, would give the possibility to illuminate these knowledge gaps.
Aim: Describe the practice (timing and duration) and outcomes of the sleep treatments 1) Cognitive Behavioral Therapy for Insomnia and 2) Chronotherapy for sleep-wake rhythm disorders at the Sleep Clinic at St. Olavs Hospital.
Method: All patients referred to the Sleep Clinic will be asked to participate before the first consultation with a clinician. Patients will be clinically assessed, diagnosed and given treatment as usual. Main outcomes will be self-report questionnaires at treatment termination and the use, timing and duration of specific sleep treatment components logged by the clinician during treatment.
Potential impact: The findings from this research project provides possibilities to improve treatment for sleep-wake disturbances by tailoring the treatment different to respective subgroups. The findings will also contribute to novel knowledge on how to treat patients with sleep-wake rhythm disorders and to what degree they benefit from the treatment in a sleep clinic.
Interventions
- Behavioral Chronotherapy
1. The effect of light exposure follows a phase-response curve where circadian phase advancement is strongest in the biological morning, whereas light in the biological evening/night may lead to a phase delay. Light therapy is provided by 30 min light exposure using 10 000 lux light boxes. 2. Melatonin 3 milligram is prescribed in tablet forms (not depot), usually 12 hours before the planned rise time. 3. Additionally, blue-light-blocking glasses are used to block light exposure at night, which - Behavioral Cognitive Behavioral Therapy for Insomnia
All participants will receive treatment as usual. CBT-I has several components and consists of the following interventions including psychoeducation about sleep: sleep hygiene, sleep restriction therapy, stimulus control, and challenging beliefs and perceptions of sleep. Special emphasis is placed on providing a rationale for behavior change as a primary means of improving sleep as well as addressing dysfunctional beliefs the patients may hold about sleep. During treatment, tapering sleep medica
