Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
