Insomnia is common in patients with co-morbid mental illness and sleeping difficulties is a frequent complaint in most psychological disorders. Mental illness may cause sleep problems, however, sleep problems like insomnia, may also cause or exacerbate mental illness. Insomnia may aggravate symptoms of depression, anxiety and fatigue, and reduce daily functioning in patients with co-morbid insomnia and mental illness. This project aims to evaluate a course offered to patients with insomnia and mental illness at Diakonhjemmet Hospital. The course is based on cognitive behavioral therapy, a documented treatment for insomnia.
