Software-delivered CBT-I for Insomnia Disorder

The goal of this prospective multicenter clinical trial is to evaluate the efficacy and safety of software-delivered cognitive behavioral therapy for insomnia (CBT-I) in Chinese patients with insomnia disorder (ID). The main questions it aims to answer are: (1) whether the software-delivered CBT-I is more effective than an online patient education (online-PE) at improving insomnia. (2) whether the software-delivered CBT-I is safe for treatment of insomnia symptoms. Participants will be randomized to receive (1) a software-delivered CBT-I using automated software called \'resleep\' (one kind of digital device expected to treat insomnia targeted for Chinese patients); (2) online patient education (online-PE) about sleep. Researchers will compare the efficacy of a software-delivered CBT-I program and an online sleep education control at improving insomnia symptoms and other psychological outcomes.
