Yuki Furukawa, a specially appointed clinician in the Department of Psychiatry and Neurology, The University of Tokyo Hospital; Masashi Sakata, assistant professor in the Department of Health Factors, Department of Social Health and Medicine, Graduate School of Medicine, Kyoto University; and Yamamoto, Department of Human Psychology, Faculty of Sociology, Edogawa University. The research group, including Professor Ryuichiro and Associate Professor Shun Nakajima of the International Research Institute for Integrative Sleep Medicine at the University of Tsukuba (director of the Cognitive Behavioral Therapy Center at the National Center for Neurology and Psychiatry *at the time of the research), used cutting-edge statistical analysis methods to For the first time in the world, we estimated the effectiveness of each component of cognitive behavioral therapy for insomnia.
Insomnia, which affects 4-22% of the population, causes pain and interferes with daily life, and it has been pointed out that it has a negative impact on daily life, reduces productivity, and increases the risk of numerous physical and mental illnesses. Cognitive behavioral therapy for insomnia (CBT-I) is considered the first choice for insomnia treatment due to its effectiveness and safety, but CBT-I consists of a combination of multiple elements, and it is unclear which elements are effective. was unknown.
Therefore, the research group conducted a systematic review of data from 241 clinical trials (31,452 participants) and elemental network meta-analysis (an analytical method to estimate the effectiveness of each element) to determine the effectiveness of each element of CBT-I. estimated about.
As a result, we found that sleep restriction methods (helping you sleep deeply by shortening the amount of time you lie down) and stimulation control methods (helping you sleep by strengthening the association between your bed and sleep), which had previously been suggested to be effective alone. In addition to cognitive restructuring (alleviating harmful beliefs about insomnia), mindfulness (accepting anxiety about insomnia), and face-to-face delivery (a delivery method in which therapists provide face-to-face treatment), the effectiveness of Ta.
On the other hand, the effectiveness of sleep hygiene guidance to adjust the sleep environment was not shown, suggesting that the effectiveness of relaxation methods such as intentionally relaxing muscles may have the opposite effect.
The results of this research will lead to the development of effective and efficient programs that include highly effective elements and omit less effective elements. It is hoped that cognitive behavioral therapy for insomnia will become more widespread and help improve insomnia.
