[Insomnia in psychiatry and psychotherapy].

Insomnia disorder is characterized by disturbed sleep continuity and associated daytime impairment. Insomnia is frequent in patients with psychiatric disorders ; 30-40% fulfill the criteria for insomnia disorder as a comorbidity. According to current guidelines, cognitive behavioral therapy for insomnia (CBT-I) is the first-line treatment, comprising sleep education, bedtime restriction, relaxation and cognitive restructuring. Despite guideline recommendations, CBT-I is insufficiently implemented, and insomnia is frequently over-treated with hypnotics. 'Become your own SLEEPexpert' is a behavioral treatment program based on CBT-I with the aim of empowering patients to take care of their own sleep health.
