Sleep in Psychiatric Care (SIP): A Transdiagnostic Group-based Sleep-school as Treatment for Comorbid Insomnia

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).

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)

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.

Measured by sleep diary; time from bed-time to rise time

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.

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 awake after sleep onset.

Measured by sleep diary; minutes awake before rise time

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 in minutes of average time in bed.

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 from 0-100% that gives average sleep efficiency.

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 in minutes of average total sleep time.

Measured by sleep diary: Time in bed minus time awake

Measured by sleep diary; subjective assesment of sleep quality on a scale from 1=very light to 5=very deep

Measured by sleep diary; subjective assesment of daytime function on a scale from 1=very good to 5=very poor

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 minutes of average sleep onset latency.

Measured by Dysfunctional Beliefs and Attitudes about Sleep (DBAS-16). The DBAS-16 measures the degree of dysfunctional beliefs about sleep with 16 items. It has 4 subscales (1) sleep-related worry and helplessness; 2) beliefs about sleep medications; 3) expectations about sleep need; and 4) beliefs about the consequences/effects of insomnia and 1 total scale score. The higher the score, the more dysfunctional beliefs about sleep.

Measured by Becks Depression Inventory -II (BDI-II). The higher the score, the more symptoms of depression

Measured by Becks Anxiety Inventory (BAI). The higher the score, the more symptoms of anxiety

Measured by Chalder fatigue Scale (CFQ). The higher the score, the more fatigued

Measured by World Health Organization well-being scale (WHO-5). The higher the score, the higher well-being.

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.

Measured by the Conners Continuous Performance (CPT) Test 3rd Edition™ (Conners CPT 3™)

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.

Measured by a visual analogue scale (VAS Pain) ranging from 0 to 10. The higher the score, the worse the pain.

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.

We will measure self-reported executive functions using the Behaviour Rating Inventory for Executive Functions Self-Report (BRIEF- SR)

We will measure systolic and diastolic pressure by a digital blood pressure measurement machine.

24 -hour HRV.

Measured by the Client Satisfaction Questionnaire (CSQ8). The CSQ-8 is an 8-item questionnaire that measures patient satisfaction with health services, where the items are rated from 1 (very low satisfaction) to 4 (very high satisfaction). The total score ranges from 8 to 32, with higher scores indicating higher degrees of satisfaction.

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.

Measured by the Karolinska Sleepiness Scale (KSS). The KSS measure subjective sleepiness at a specific time point (noon). The scale gives a number from 1-9 where 9 indicates "trouble staying awake" and is the worst outcome.
