| Research Abstract |
The aims of this study were to conduct cognitive behavioral therapy for insomnia (CBT-I) by which the effect has been clarified in western countries, and to examine the efficacy of the treatment in Japan. In this study, (1)a community based longitudinal study of relationship between insomnia and depression, (2)meta-analysis of standard CBT-I for chronic insomnia, and (3)effectiveness of CBT-I on patients with hypnotics-dependent chronic insomnia were examined. These results suggested that (1)the new appearance and continued existence of depression at the follow-up were related to the persistent insomnia, (2)standard CBT-I was the effective treatment for chronic insomnia, and (3)conducting CBT-I decreased insomnia and depressive symptoms, despite reducing the amount of the hypnotics.
