About this study

Official title: Blue-blocking Glasses for Treating Evening Activation and Sleep Disorders in Child and Adolescent Psychiatry - a Pilot Trans-diagnostic Randomized Controlled Trial.

Sleep problems and regulation difficulties are frequent in the child and adolescent psychiatry population. Insomnia and delayed sleep-wake phase disorders (DSPWD) are highly prevalent, and risk factors for developing more severe illness courses and chronic disorders. Pharmacological treatments of sleep disorders dominate even for the youngest patients but are unsupported by long-term data on outcome and side effects. The majority of non-pharmacological treatment options are composite and resource demanding. The investigators will examine the effects and feasibility of the isolated intervention of evening/night use of blue-blocking glasses/real darkness as adjunctive treatment for insomnia and delayed sleep phase disorder in inpatient and outpatient settings for children and adolecents.

Read the detailed description

The investigators will conduct a pilot study to examine the effect and feasibility of blue-blocking glasses as adjunctive treatment for insomnia and delayed sleep phase disorder in child and adolescent inpatients and outpatient settings. If the intervention and protocol are feasible and promising with regards to clinical and physiological effects, the study will provide a sound base for planning larger multicenter RCT's. Blue-blocking glasses are a minimal risk, low-cost intervention, and have potential to improve illness-course through improved sleep and healthier circadian function. The intervention may reduce the need for pharmacological treatment for sleep and circadian disorders and enhance coping strategies for the adolescents and their caregivers. Lastly, the pilot study will yield much needed data on light conditions (daylight and nightlight) in hospital environments for children and adolescents and may contribute to improved sleep conditions in hospital wards.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change form baseline in sleep onset latency (SOL) at 1 week

    Sleep onset latency (minutes) subjectively assessed in sleep diary and objectively assessed from actigraphy derived sleep parameters. Sleep onset latency describes how long it takes to fall asleep from the moment the person tries to fall asleep to sleep starts.

    Measured: From baseline to after 1 week of intervention. For outpatients, SOL is also measured after 2 weeks of intervention.

  2. Change from baseline in overnight melatonin production at 1 week

    Quantity of melatonin metabolite 6-sulphatoxymelatonin (aMT6s) in the total overnight urine volume (µg).

    Measured: From baseline after 1 week of intervention. For outpatients 6-sulphatoxymelatonin, is also analyzed after 2 weeks of intervention.

Secondary outcomes (9)
  1. Affektive Reactivity Index, relf reported (ARI-S)

    Self-report form for rating irritability, minimum value 7, maximum value 21, high score indicates worse outcome.

    Measured: From baseline to after 7 days of intervention. For outpatients ARI-S and ARI-P are also assessed after 14 days of intervention.

  2. Self-report Generalized Anxiety Disorder -7 (GAD-7)

    GAD-7 is 7- item self-report questionnaire used for rating general symptoms of anxiety, minimum value 7, maximum value 28, high score indicates worse outcome.

    Measured: From baseline to after 7 days of intervention. For outpatients, ARI-S and ARI-P are also assessed after 14 days of intervention.

  3. Patient Health Questionnaire (PHQ-9)

    PHQ-9 is a nine-item self-report questionnaire rating depressive symptoms, minimum value 9, maximum value 36, high score indicate worse outcome.

    Measured: From baseline to end of 7 days intervention. For outpatients, PHQ-9 is also assessed after 14 days of intervention.

  4. KID-SCREEN-10

    The KID-SCREEN 10 is self report instrument for assessing quality of life for children and adolescents, minimum value 10, maxium value 50, high score indicates better outcome.

    Measured: From baseline to end of 7 days intervention. For outpatients KIDSCREEN-10 is also assessed after 14 days of intervention.

  5. Reduced version Horne-Østberg Morningness Eveningess Questionnaire (r-MEQ)

    The r-MEQ is a self report questionnaire for assessing morning or evening preference of the sleep/wake cycle, minimum value 4, maximum value 25, high score indicates morning type ("lark"), low score indicates evening type ("owl").

    Measured: From baseline to after 7 days of intervention. For outpatients r-MEQ is also assessed after 14 days of intervention.

  6. Bergen Insomnia Scale (BIS)

    BIS is a self report questionnaire for diagnostic support (insomnia) and as a contiunous outcome variable. We will use BIS in the inclusion procedure but also repeat it as a subjective outcome measure of sleep problems and daytime function. Minimum value 0, maksimum value 42, high score indicate worse outcome.

    Measured: From baseline to after 7 days of intervention. For outpatients, BIS is also assessed after 14 days of intervention.

  7. Motor activity

    GENEActive wristworn actigraph with RGB light sensor, (Active Insights, Manchester, UK). Motor activity/motor activity derived sleep outcomes (other than primary outcome) include: Total sleep time (sleep diary, actigraphy)

    • Wake after sleep onset
    • Motor activity in sleep interval
    • Sleep efficency
    • Sleep onset
    • Sleep offset
    • Mid-sleep time
    • Motor activity patterns (circadian, motor variabilty, complexity)

    Measured: From baseline to after 7 days of intervention. For outpatients, parameters are also assessed after 14 days of intervention.

  8. BioPoint biosensor

    The BioPoint sensor is a physiological multisensor worn as a watch measuring heart rate, heart rate variability, peripheral skin impedance, peripheral temperature

    Measured: During first and 7th day of intervention (inpatients), during 7th and 14 days of intervention (outpatients) For all patients the outcomes will be compared to baseline assessments.

  9. Affektive Reactivity Index, parent-reported (ARI-P)

    Proxy (care-giver) report form for rating irritability, minimum value 7, maximum value 21, high score indicates worse outcome.

    Measured: From baseline to after 7 days of intervention. For outpatients ARI-S and ARI-P are also assessed after 14 days of intervention.
