[Correspondence] Evidence-based psychological therapies for insomnia
We read with interest Kimberly Whitehead and Matthew Beaumont’s Perspective1 (June 16, p 2408). As clinicians and researchers working on insomnia over the past three decades, we can only agree that the cultural and historical conditions under which insomnia occurs indeed shape the condition. However, we would like to stress that today’s psychological therapies for insomnia2 go far beyond sleep hygiene as stated in the perspective. Cognitive behavioural treatment for insomnia (CBT-I) has evolved as a mainstay of modern insomnia treatment, encompassing sleep hygiene; education about sleep; relaxation techniques; behavioural techniques, such as stimulus control and sleep restriction; and cognitive techniques to reduce nocturnal ruminations.
