Sleep problems include insomnia, circadian rhythm disorders, hypersomnia, and inadequate sleep hygiene. Patients suffering from mental illness are more likely to suffer from sleep problems than the general population. Sleep problems can aggravate the underlying disorder, cause relapse and suicidal ideation. Sleep problems often persist after the mental disorder is successfully treated. Sleep medication is often used but not recommended for long term use. Non-pharmacological treatment of sleep problems is in demand by patients, but treatment options are few. The present intervention is based on a transdiagnostic manual combining Cognitive Behavioral Therapy for Insomnia with chronotherapy, but more research on the efficacy is warranted.
The aim of this study is to investigate whether the intervention reduces the severity of the sleep problem, increases sleep quality, leads to increased sleep efficiency, reduces sleep latency and awakenings, provides better quality of life, increases personal recovery, provides greater readiness to take on a job or reduces consumption of sleep medication.
