Abstract

Introduction: Previous evidence suggested that online self-guided sleep intervention is efficacious in improving treatment outcomes in patients with chronic insomnia [corrected]. However, research on online sleep interventions targeting acute insomnia [corrected] has been scarce. This study aims to evaluate the effectiveness of brief e-aid cognitive behavioural therapy for insomnia (eCBTI) in preventing transition from acute insomnia to chronic insomnia [corrected].

Methods and analysis: This is a pragmatic two-arm multicentre, randomised controlled trial comparing eCBTI with treatment as usual (TAU) in outpatients. Two hundred patients with acute insomnia [corrected] (as defined by DSM-5) will be recruited. Patients will be randomly assigned to receive 1 week eCBTI via a Smartphone application, or to receive TAU. Treatment effects will be assessed at 1 week and 3 months after intervention. The primary outcome of the study, whether the eCBTI program is sufficient in preventing transition from short-term to chronic insomnia [corrected], is measured by the Insomnia Severity Index. Secondary outcome measurements include the Dysfunctional Beliefs and Attitudes about Sleep Scale, Ford Insomnia Response to Stress Test, Sleep Hygiene and Practices Scale, Pre-sleep Arousal Scale and Epworth Sleepiness Scale. Additionally, the Hospital Anxiety and Depression Scale and the Short-Form 12-Item Health Survey will be used for measurement of mood symptoms and quality of life.

Ethics and dissemination: Ethical approval for the study has been obtained from the Ethics Committee of Southern Medical University (reference number: NFEC-2017-131). The results of the investigation will be published in scientific papers. The data from the investigation will be made available online if necessary.

Trial registration: NCT03302455 (clinicaltrials.gov). Date of registration: October 5, 2017.

Keywords: E-aid cognitive behavior therapy for insomnia (eCBTI); episodic insomnia; randomised controlled trial (RCT).
