Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study is a single-blinded randomized waitlist controlled trial that aims to assess changes in objective and self-report sleep improvement through use of a dynamic and personalized sleep improvement smartphone app and advice engine in those with poor sleep (i.e., subclinical threshold insomnia) when compared to a waitlist control group after 6 weeks and 12 weeks.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Subclinical sleep dysfunction has a multitude of causes (e.g., environmental, cognitive, behavioral, or physiological) and symptoms (e.g., long sleep onset latency, short sleep duration, elevated wake after sleep onset and nighttime awakenings, poor sleep quality). A personalized and dynamic sleep improvement intervention tailored to an individual's lifestyle and specific needs may therefore be required to help nudge those with poor sleep towards sleep-promoting behaviors and attitudes. Digital and mobile health platforms are also highly scalable and cost-effective, thus allowing for widespread implementation across larger subclinical populations.

The purpose of the present study is to conduct a single-blinded randomized waitlist controlled trial to evaluate a novel smartphone application, Dein Schlaf. Dein Tag. powered by SleepScore, designed to both objectively measure and improve sleep. The Dein Schlaf. Dein Tag. app features a validated sonar sleep measurement tool and also provides dynamic and personalized sleep advice founded in the principles of cognitive behavioral psychology and sleep hygiene, offering a non-invasive and non-pharmacological behavioral intervention designed to improve sleep and circadian functioning in those with common sleeping difficulties. Participants will be randomly assigned to the sleep improvement app intervention or a waitlist control group. Online assessments on validated sleep and preventative health measures will take place at baseline, 6 weeks, and 12 weeks.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Allocation to Sleep Improvement App

Participants will be instructed to engage with the Dein Schlaf. Dein Tag. smartphone app, log their behaviors in-app, and track their sleep daily for the duration of the study (12 weeks). Participants will be instructed to start the sleep tracking device via their iOS device before lying down in bed and turning off the lights to go to sleep. In the morning, participants will turn off the sleep tracking device as soon as they wake up and decide to leave the bed. At the three time points (baseline, 6 weeks, and 12 weeks), participants will be instructed to complete online assessments on self-reported sleep quality, health perception, psychosocial factors and sleep-permissive behaviors (i.e., preventative health)

Group Type ACTIVE_COMPARATOR

Dein Schlaf. Dein Tag. sleep improvement application powered by SleepScore

Intervention Type BEHAVIORAL

The Dein Schlaf. Dein Tag. application powered by SleepScore is a validated sleep measurement application using sonar technology that also provides evidenced-based sleep advice and sleep education content based on a user's objectively measured nightly sleep data. As participants engage with the app, the Dein Schlaf. Dein Tag. application provides personalized and dynamic sleep content and sleep and circadian rhythm improvement advice based in the principles of sleep hygiene, sleep-circadian science, and cognitive behavioral psychology. Participants will also receive personalized sleep challenges tailored to improve their sleep and circadian rhythms. Each challenge lasts for 7 tracked nights, ranging from optimizing sleep habits to limiting caffeine intake, and more. Additional sleep improvement features embedded within the app include sleep sanctuary bedroom checks, sleep sounds, smart alarms, bedtime reminders, and sleep education blogs and science content.

Allocation to Waitlist Control Group

At the three time points (baseline, 6 weeks, and 12 weeks) participants assigned to the wait-list control group will be instructed to complete online assessments on self-reported sleep quality, health perception, psychosocial factors and sleep-permissive behaviors (i.e., preventative health)
