Background and study aims
Chronotherapy (including light therapy) helps adults suffering from depression to get better. This initial study investigates the possible effects of chronotherapy on mood, attention and sleep in children and adolescents.
Who can participate?
You can be included when you are an inpatient between the age of 12 and 18 with a moderate to severe depression and you do not get any medication (antidepressants, neuroleptics or beta-blocker).
What does the study involve?
You will receive morning light therapy for 14 consecutive days, each day for 45 minutes at an individually determined time point that fits your biological sleep rhythm (whether you are a morning, evening or in-between type)
Two groups are compared: you either receive active light therapy with 10.000 Lux or inactive light therapy with 100 Lux
Psychological and physiological tests are made before and after the intervention and again after a few weeks to investigate changes of your depression, sleep rhythm and other parameters
What are the possible benefits and risks of participating?
Benefits of chronotherapy include symptom amelioration, additional therapeutic offer for inpatients, possibility of a treatment without medication, high predictability of the mechanisms of action.
Possible risks of chronotherapy include headache, nausea, irritability, burning eyes, unexpected awakening during the night.
Where is the study run from?
The study takes place in the LWL-University Hospital Hamm in Germany
When is the study starting and how long is it expected to run for?
The study started in August 2011 and will last until August 2014.

| Scientific title | Chronotherapy in children and adolescents with depression and affective dysregulation: a double-blind randomized controlled trial |
| Study objectives | In adults, chronotherapy has been established as an adjunctive treatment for major depression, not only for seasonal affective disorder. Preliminary results indicate that chronotherapy (light therapy, sleep deprivation, sleep phase advance) might also be helpful more generally for disorders with a disturbed circadian rhythm, such as for attention defecit hyperactivity disorder (ADHD) and affective dysregulation. Up to date, the efficacy of chronotherapy for children and adolescents has not been investigated before. The primary objective in a first pilot trial is to investigate the effects of light therapy on depression and affective dysregulation in children and adolescents. |
| Ethics approval(s) | Ethics Committee of the Department of Medicine, Ruhr University Bochum approved on 27th June 2011 (ref: 3996-11) |
| Health condition(s) or problem(s) studied | Juvenile depression and affective dysregulation |
| Intervention | Patients will be randomly assigned to the following two groups (1:1). Experimental group 45 min morning light therapy (10.000 Lux, DAVITA LD 110) approx. 8.5 h after estimated melatonin-onset (DLMO, assessed by the morningness-eveningness-questionnaire (MEQ)) for 14 consecutive days. When theres no improvement of depressive symptoms within the first 3 days of the intervention (assessed by the BDI II), the duration can be prolonged to 60 min to reach maximal effects. Control group 45 min "inactive morning light therapy (approx. 100 Lux, DAVITA Luxor LED), approx. 8.5 h after estimated melatonin-onset (DLMO, assessed by the morningness-eveningness-questionnaire (MEQ)) for 14 consecutive days. A luxmeter (PCE-172) will ensure that the number of lux will be held constantly low. After a "light therapy" pilot trial has been conducted, a combination trial with sleep deprivation (wake therapy), sleep phase advance and early morning light therapy will be realised. |
