Outline of Final Research Achievements

An RCT was conducted to test whether 4 weeks of Internet Cognitive Behavioral Therapy (ICBT) or "3 Good Things" Exercise (TGT) is effective for insomnia problems. A total of 312 adults with insomnia problems were randomly assigned (Internet Cognitive Behavioral Therapy: 106 in the ICBT group, "3 Good Things" exercise: 103 in the TGT group, and waiting: 103 in the WLC group), and PSQI scores at 4 and 8 weeks were analyzed for 270 participants after the 4-week intervention period. The results of the analysis showed that at 4 weeks, both the ICBT and TGT groups had significantly lower PSQI than the WLC group.

Academic Significance and Societal Importance of the Research Achievements

必ずしも改善につながらない睡眠薬による治療が、長期連用、依存、多剤併用等の問題を起こし、生活習慣病と同様に、不眠に対しても薬物治療だけでなく、エビデンスに基づいた生活指導を導入することの意義が示された。不眠についての不安を高めるような認知や行動の悪循環のパターンの変容を促す認知行動療法が治療の第一選択として活用されることで、利用しやすいインターネット上の生活指導としての不眠改善プログラムを提供することができれば、多くの人々の生活の質（QOL）の向上や医療費の適正化が期待できる。
