| Outline of Final Research Achievements |
We developed web-based cognitive behavioral therapy for insomnia (web-CBTi) based on the previous studies and our clinical practices. A randomized controlled trial of web-CBTi was conducted. The web-CBTi is 5 weekly program including in recording sleep diary (week1), sleep hygiene (week2), progressive muscle relaxation (week3), and sleep scheduling (week4, week5).
Patients with chronic insomnia disorder assigned randomly to web-CBTi (n = 24) or sleep hygiene education (SHE; n = 26). It is revealed that web-CBTi had mild effects of improvement on anxiety (d = 0.23) and depression (d = 0.26) related to SHE.
