EFFICACY OF A THEORY-BASED COGNITIVE BEHAVIORAL TECHNIQUE APP-BASED INTERVENTION FOR PATIENTS WITH INSOMNIA : RANDOMIZED CONTROLLED TRIAL

• Introduction: Sleep hygiene is important for maintaining good sleep andreducing insomnia. This study examined the long-term efficacy of a theory-based app(including cognitive behavioral therapy [CBT], theory of planned behavior[TPB], health action process approach [HAPA], and control theory [CT]) onsleep hygiene among insomnia patients. Materials and Methods: The study was a 2-arm single-blind parallel-group randomized controlled trial (RCT). Insomnia patients wererandomly assigned to a treatment group that used an app for 6 weeks (ie,CBT for insomnia [CBT-I], n¼156) or a control group that received onlypatient education (PE, n¼156) through the app. Outcomes were assessedat baseline and 1 month, 3 months, and 6 months postintervention. Pri-mary outcomes were sleep hygiene, insomnia, and sleep quality. Second-ary outcomes included attitudes toward sleep hygiene behavior, perceived behavioral control, behavioral intention, action and coping planning, self-monitoring, behavioral automaticity, and anxiety and depression. Linear mixed models were used to evaluate the magnitude of changes in out-comes between the two groups and across time. Results: Sleep hygiene was improved in the CBT-I group compared with the PE group (P¼.02 at 1 month, P¼.04 at 3 months, and P¼.02 at 6 months) as were sleep quality and severity of insomnia. Mediation analyses suggestedthat perceived behavioral control on sleep hygiene as specified by TPBalong with self-regulatory processes from HAPA and CT mediated the ef-fect of the intervention on outcomes. Conclusions: Health care providers might consider using a CBT-I app toimprove sleep among insomnia patients.
