Cognitive behavioral therapy for insomnia (CBT‑I) is the most effective psychological treatment for a health problem. 80% of patients treated with CBT‑I fall asleep faster, 80% report clinical improvement in sleep, and 90% reduce or eliminate sleep medications. CBT‑I doubles the improvement rates of depression compared to antidepressant medication alone in depressed patients with insomnia. Patients treated with CBT‑I also experience improvement in comorbidities, such as menopausal hot flashes, pain, fibromyalgia, depression, PTSD, and substance abuse. CBT‑I produces rapid improvement in sleep in five treatment sessions over six weeks. It is recommended by the American College of Physicians as the first line treatment for chronic insomnia in adults. (Jacobs, 2000)
