Study of Efficacy of Digital Cognitive Behavioral Therapy With Wearable Device for Insomnia

Yonsei University30 enrolled

Overview

The purpose of the study was to examine safety and efficacy of cognitive behavioral therapy (CBT)-based wearable integrated digital therapeutics for insomnia patients

The investigators intend to conduct a single-arm clinical trial. Following voluntary consent during the screening visit, participants will undergo screening procedures. The screening process will proceed step by step, evaluating selection/exclusion criteria through assessments such as the Mini International Neuropsychiatric Interview (MINI), Columbia Suicide Severity Rating Scale (C-SSRS), etc. Participants who meet the selection criteria and do not meet the exclusion criteria will use the DTx app for 8 weeks. Surveys conducted after app installation (Insomnia Severity Index (ISI), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder 7-item Scale (GAD-7), and a sleep environment questionnaire) will serve as the baseline. During the clinical trial period, sleep diaries and compliance (lesson completion rate) (applicable only to the experimental group) will be collected through the app. Sleep diaries will be used to evaluate sleep metrics such as sleep efficiency (SE), sleep onset latency (SOL), wake after sleep onset (WASO), etc. For the experimental group, assessments as per the protocol will be conducted at baseline (Visit 1), and safety (adverse events) evaluation and termination of app usage will occur at 9 weeks (Visit 2).

Interventions

WELT-IP with wearable devices (Apple/galaxy watch. Oura ring)DEVICE

WELT-IP (an investigational digital therapeutic) is an CBT-I based intervention designed to treat insomnia, conducted in 6 sessions. It is a comprehensive program delivering sleep restriction, stimulation control, muscle relaxation, cognitive treatment, and sleep hygiene education. Main features are sleep diary, sleep reports, daily lessons of CBT-I, muscle relaxation techniques, and cognitive intervention through chatbot. By using WELT-IP simultaneously with wearing an Apple Watch/Galaxy Watch and Oura Ring, sleep and environmental data can be collected.

Outcomes

Primary Outcomes

Change from baseline to week 9 (post-treatment) of ISI

Change from baseline to week 9 (post-treatment) of ISI. ISI has 7 questions. Total score ranges from 0 to 28, where higher scores indicate more acute symptoms of insomnia.

Time frame: 9 weeks

Secondary Outcomes

Secondary Outcome - Changes from baseline to week 9 of SE

Change from baseline to week 9 (post-treatment) of SE. Sleep efficiency is calculated as percentage of total sleep time/time in bed.

Time frame: 9 weeks

Changes from baseline to week 9 of SOL.

Change from baseline to week 9 (post-treatment) of SOL. Sleep onset latency is evaluated as the time it takes a person to fall asleep after going to bed.

Time frame: 9 weeks

Changes from baseline to week 9 of WASO.

Change from baseline to week 9 (post-treatment) of WASO. WASO is calculated as the total number of minutes that a person is awake after initially falling asleep.

Time frame: 9 weeks

Changes from baseline to week 9 of PHQ-9.

Change from baseline to week 9 (post-treatment) of PHQ-9. PHQ-9 has nine questions. Total score ranges from 0 to 27, where higher scores indicate more acute symptoms of depression.

Time frame: 9 weeks

Changes from baseline to week 9 of GAD-7.

Change from baseline to week 9 (post-treatment) of GAD-7. GAD-7 has seven questions. Total score ranges from 0 to 21, where higher scores indicate more acute symptoms of anxiety.

Time frame: 9 weeks

Changes from baseline to week 9 of compliance.
