Cognitive behavioral therapy for insomnia (CBT-I) has emerged as the standard first-line treatment for insomnia. The number of patients receiving non-medication treatments is increasing, and there is a growing need to address a wide range of patient backgrounds, characteristics, and medical and psychiatric comorbidities. Adapting Cognitive Behavioral Therapy for Insomnia identifies for clinicians how best to deliver and/or modify CBT-I based on the needs of their patients. The book recommends treatment modifications based on patient age, comorbid conditions, and for various special populations.
