About this trial
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.

Trial outcomes
Primary outcomes
Insomnia symptoms
Measured by the questionnaires Insomnia severity Index (ISI) and Bergen Insomnia Scale (BIS). From sleep diaries; sleep onset latency (SOL), wake after sleep onset (WASO) and sleep efficiency (SE).
Secondary outcomes
Changes in insomnia diagnosis
Measured by the Bergen Bergen Insomnia Scale (BIS). The BIS measure subjective symptoms of insomnia during the previous week and give a total score (minimum 0, maximum 42; the higher the score, the worse severity of insomnia) and a clinical incidence of insomnia diagnosis-score (yes/no)
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.
Changes in Time in bed (TIB)
Measured by sleep diary; time from bed-time to rise time
Changes in objective early morning awakening (EMA)
Measured by Actiwatch (AW) Spectrum PLUSS. The activity recorder is worn on the wrist for 7 consecutive days. The data is downloaded to a computer program that gives the data; a number of average minutes early morning awakening.
Other outcomes
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.
Changes in vigilance
Measured by the Conners Continuous Performance (CPT) Test 3rd Edition™ (Conners CPT 3™)
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.
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.
