Effectiveness of an mHealth Intervention for Infant Sleep Disturbances

Area of Science:

• Pediatrics
• Behavioral Science
• Public Health

Background:

• Infant sleep problems and night wakings are common issues for caregivers.
• Existing behavioral sleep interventions often lack real-world accessibility and scalability.

Purpose of the Study:

• To evaluate the real-world effectiveness of a mobile health (mHealth) behavioral sleep intervention, the Customized Sleep Profile (CSP).
• To assess changes in infant sleep patterns and caregiver behaviors using the CSP app.

Main Methods:

• A total of 404 infants (6-11.9 months) and their caregivers used the free, publicly available CSP smartphone application.
• Caregivers completed the Brief Infant Sleep Questionnaire-Revised (BISQ-R) at baseline and follow-up (4-28 days).
• Sleep outcomes were analyzed based on infant sleep problem status (problem vs. no problem sleepers).

Main Results:

• Sleep onset latency improved for all infants; earlier bedtimes and longer sleep stretches were observed in infants with prior sleep problems.
• Infants with sleep problems showed decreased night wakings and improved caregiver-reported sleep quality and behavioral changes.
• Both groups experienced improvements in overall sleep time and bedtime routine regularity, with greater changes in the problem-sleeper group.

Conclusions:

• A publicly available mHealth behavioral sleep intervention (CSP) is effective in improving infant sleep outcomes in real-world settings.
• The intervention led to positive changes in caregiver behavior and sleep-related outcomes, even with short-term use.
• mHealth interventions offer a scalable and accessible approach to addressing common infant sleep challenges.
