The study is a single-blind study, parallel randomized controlled trial method. The purpose of this study was to explore the effectiveness of the mobile version of Application based Brief Behavioral Treatment for Insomnia (BBTI-APP) and the interactive e-book version of BBTI in improving the severity of insomnia, sleep quality and mood among college students. Measurement outcomes are sleep parameters measured by the Chinese version of Insomnia Severity Index, Chinese version of The Depression, Anxiety and Stress Scale - 21 Items, and sleep diary. Questionnaires will be assessed in pretreatment, posttreatment, and one-month follow-up. We hypothesized that compared with the sleep hygiene group, both the BBTI-APP and the interactive e-book BBTI can significantly improve college students' insomnia symptoms, emotional distress, and quality of life.
