Efficacy of Mobile App–Based Cognitive Behavioral Therapy for Insomnia: Multicenter, Single-Blind Randomized Clinical Trial

Abstract

Background: Cognitive behavioral therapy for insomnia (CBTi) is the first-line therapy for chronic insomnia. Mobileapplication-based CBTi (MCBTi) can enhance the accessibility of CBTi treatment; however, few studies have evaluated the effectiveness of MCBTi using a multi-center, randomized controlled trial (RCT) design. Objective:We aimed to assess the efficacy of Somzz, an MCBTi that provides real-time and tailored feedback to users, comparing with an active comparator application.
