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.
