Clinical Trial Summary

Sleep disorders commonly co-occur with psychiatric disorders. Sleep disorders are often treated with medication or not at all in psychiatric care, although there exist a plethora of documentation of the effectiveness of sleep interventions. There is also an increase in studies showing effectiveness of sleep-interventions when the sleep disorder co-occurs with psychiatric illness. The most common and best documented treatment for insomnia is cognitive behavioral therapy for insomnia (CBTi). There is a great gap in the knowledge on how sleep disorders can be treated effectively in psychiatric care. In this project the investigators therefore seek to investigate the effect of non-pharmacological, group-based treatment in a randomized controlled trial (RCT) where sleep and psychiatric symptoms are the primary outcome measures. CBTi comprise of sleep education, sleep restriction, stimulus control and cognitive restructuring of dysfunctional thoughts about sleep.

Description:

The recommended treatment for insomnia is CBTi. Recent research has proven that dark therapy, or blocking light in wavelengths <530 nm by the use of for example orange blue-blocking glasses (bb-glasses), has shown the ability to maintain melatonin production comparable to darkness and to have an additive effect in the treatment of insomnia. The investigators therefore also want to test bb-glasses as an additive treatment to CBTi for insomnia.

The sleep-school at Bjørgvin District Psychiatric Hospital (DPS) is an already established treatment since 2017. The insomnia-group gets together every other Monday from noon until 2 pm. The group is open, which means that participants start at different dates and meet people in the group that might be at the end of their CBTi treatment. Participants are patients at the general psychiatric outpatient clinic at Bjørgvin DPS. Participant have been referred to the sleep-team by their psychologist or doctor. In this RCT the investigators will carry on the same structure for the group for participants that are recruited to the RCT.

All participants have an individual consultation before joining the group where the focus is on eligibility to participate in the group-based treatment, diagnostic evaluation, receive a standardized education on sleep-regulation and sleep hygiene advice and receive a date to start the group-based CBTi treatment. In a randomized manner, they will be allocated to the sleep-school group and start the treatment on the next possible date or to a 8 week wait-list and receive a date the treatment starts. All eligible participants will be informed that there may be a waitlist and receive a start-date without being informed that thay are in a waitlist group or not a waitlist group. All participants will be treated as usual (TAU) for their psychiatric problems parallel to either sleep-school or waitlist. Participants that start sleep-school as soon as possible, are also allocated to a) ordinary group-based CBTi 8 weeks or b) group-based CBTi 8 weeks and bb-glasses. All participant will be followed up after 12 months.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Changes in symptoms of inattention	Measured by the Adult attention deficit hyperactivity disorder (ADHD) Self-Rating Scale (ASRS). The scale contains the 18 symptoms of inattention, hyperactivity, and impulsivity defining ADHD according to the DSM-IV-TR and DSM-5. The severity of the symptoms are reported on a 5-point Likert-type scale (0-4 = never, rarely, sometimes, often, to very often), with a total range of 0-72. The higher the score, the more symptoms of inattention.	baseline and post intervention after 8 weeks, follow-up after 12 months
Other	Changes in vigilance	Measured by the Conners Continuous Performance (CPT) Test 3rd Edition™ (Conners CPT 3™)	baseline and post intervention after 8 weeks, follow-up after 12 months
Other	Changes in self reported emotion regulation ability	Measured by Difficulties in Emotion Regulation Scale (DERS) which is a 18-item self-report measure of six facets of emotion regulation. Items are rated on a scale of 1 ("almost never [0-10%]") to 5 ("almost always [91-100%]"). Higher scores suggest greater problems with emotion regulation.	baseline and post intervention after 8 weeks, follow-up after 12 months
Other	Changes in degree of experienced pain	Measured by a visual analogue scale (VAS Pain) ranging from 0 to 10. The higher the score, the worse the pain.	baseline and post intervention after 8 weeks, follow-up after 12 months
Other	Changes in symptoms of hypochondria	Measured by the The Whiteley Index (WI). The 14-item WI measures assess health anxiety on a likert-scale from 1="not at all" to "5=very much". The higher the score, the more severe health anxiety.	baseline and post intervention after 8 weeks, follow-up after 12 months
Other	Changes in executive functions	We will measure self-reported executive functions using the Behaviour Rating Inventory for Executive Functions Self-Report (BRIEF- SR)	baseline and post intervention after 8 weeks, follow-up after 12 months
Other	Changes in blood pressure	We will measure systolic and diastolic pressure by a digital blood pressure measurement machine.	baseline and post intervention after 8 weeks, follow-up after 12 months

The total score ranges from 8 to 32, with higher scores indicating higher degrees of satisfaction.	post intervention after 8 weeks
Other	Changes in sleepiness	Measured by the Epworth Sleepiness Scale (ESS). The ESS is an 8-item scale where the respondent grades the likelihood of falling asleep or dozing off in different daily situations. The responses are graded on a 4-point likert scale 0=no likelihodd to 3=very likely. A score of 11 or higher is considered an indication of excessive daytime sleepiness.	baseline, bi-weekly assesment and post intervention after 8 weeks, follow-up after 12 months

Secondary	Changes in insomnia severity	Measured by the Insomnia Severity Index (ISI). The ISI is a 7-item scale assessing the perceived severity of insomnia symptoms (initial, middle, terminal), the degree of satisfaction with sleep, interference with daytime functioning, noticeability of impairment, and concern caused by the sleep problems. The scale is Likert-type with 5 anchor points ranging from 0 to 4. The scale ranges from 0 to 28 and the higher the score, the more severe insomnia. The usual time frame for responding is the last 2 weeks.	baseline and post intervention after 8 weeks, follow-up after 12 months
