Treatment of insomnia disorder in psychiatry: A practical guide for CBT-I based intervention.

Insomnia disorder is highly prevalent among patients with psychiatric disorders and significantly impacts the course and prognosis of these disorders. Interventions based on cognitive behavioral therapy for insomnia (CBT-I) are considered the first-line treatment for adults, both with and without psychiatric comorbidities. This article provides a practical guide for clinicians, beginning with a definition of insomnia and its diagnostic criteria, followed by a detailed description of the core components of CBT-I: psychoeducation, including the key information to convey to patients; behavioral strategies, with recommendations tailored to individuals with psychiatric comorbidities; and cognitive interventions aimed at addressing maladaptive beliefs and thought patterns related to sleep.
