Insomnia, Psychiatric Disorders
Conditions
Brief summary
The goal of this investigator-initiated, randomized, blinded, 3-armed placebo-controlled, pragmatic, clinical superiority trial is to examine the efficacy of melatonin or low-dose quetiapine versus placebo for treatment of insomnia in patients with psychiatric disorders. The aims of the study are: * To examine the efficacy of melatonin or low-dose quetiapine versus placebo for treatment of insomnia * To examine how melatonin or low-dose quetiapine affects global symptom severity, sleep quality, psychosocial functioning and subjective well-being. Participants will receive six weeks of treatment with either melatonin, quetiapine or placebo followed by a brief taper off.
Interventions
3-9 mg flexible dosing before bed time
50-150 mg flexible dosing before bed time
1-3 capsules flexible dosing before bed time

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Insomnia severity | 6 weeks | Insomnia Severity Index, range 0-28, higher is worse |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical global impression (CGI) | 6 weeks | Clinical global impression: Severity, range 0-7, higher is worse |
| Subjective sleep quality | 6 weeks | Pittsburgh Sleep Quality Index, range 0-21, higher is worse |
| Psychosocial functioning | 6 weeks | Personal and Social Performance Scale, range 1-100, higher is better |
| Patient-reported subjective well-being | 6 weeks | WHO-5 well-being index, range 0-100, higher is better |
Other
| Measure | Time frame | Description |
|---|---|---|
| Objective sleep quality (polysomnography) | 6 weeks | Total sleep time in minutes, higher is better |
| Circadian rhythmicity (actigraphy) | 6 weeks | Interdaily stability which quantifies the invariability from day to day, i.e., the predictability of the 24 h rest-activity pattern. This index will be 1 for perfect interdaily stability and thus lower values reflect higher variability between the observed days |
