About

The goal of this clinical trial is to learn whether the SleepQ mobile app can help reduce insomnia symptoms in adults diagnosed with insomnia. The main questions it aims to answer are:

Does adding the SleepQ app to care as usual (CAU) improve insomnia symptoms after 12 weeks?
Does SleepQ also improve depressive symptoms, anxiety, beliefs about sleep and daily functioning?

Researchers will compare CAU + SleepQ to CAU alone to see whether SleepQ provides additional benefits for sleep and well-being.

Participants will take part remotely from home, be randomly assigned to either SleepQ+CAU or CAU alone, and complete online questionnaires at baseline, week 6, and week 12 about their sleep, mood, and daily functioning.

Participants in the intervention group will use the SleepQ app for 12 weeks while continuing their usual care.

Full description

SleepQ is digital CBT-I application developed to align with national clinical guidelines for the treatment of sleep disorders. The program includes psychoeducation, sleep restriction therapy, stimulus control, sleep hygiene approaches, cognitive restructuring, and relaxation exercises. The app also incorporates a digital sleep diary, personalized sleep timing recommendations, interactive learning modules, quizzes to reinforce concepts, and monitoring of therapy progress. The overall design aims to support engagement and autonomous adherence to CBT-I principles by providing step-by-step guidance and feedback throughout the therapeutic course.

The pilot clinical trial will evaluate the effectiveness of SleepQ as an add-on to care as usual (CAU) compared with CAU alone in adults diagnosed with insomnia. Approximately 80 adult participants with a confirmed diagnosis of insomnia will be enrolled and randomized in a 1:1 ratio to the intervention group (SleepQ + CAU) or the control group (CAU alone). The study will be conducted as a fully decentralized trial within Germany. Screening, informed consent, eligibility confirmation, randomization, and all outcome assessments will be conducted remotely. Participants will complete self-reported questionnaires at baseline, week 6, and week 12 to assess changes in insomnia severity and related symptoms.

The primary endpoint is the reduction in insomnia symptoms after 12 weeks, and secondary outcomes include changes in depressiv symptoms, anxiety, dysfunctional beliefs about sleep, and daily functioning.
