This pilot study supports the feasibility, acceptability, and preliminary effectiveness of a digital circadian-based intervention to improve sleep among nurse leaders.
Key Findings
Results
The digital sleep intervention produced significantly greater improvements in sleep disturbance compared to waitlist controls.
Effect size was large (d = 1.44; P < .001)
Measured using the PROMIS Sleep Disturbance 8b validated instrument
Study duration was 4 weeks
40 nurse leaders were randomized to intervention or waitlist control
Results
The digital sleep intervention produced significantly greater improvements in insomnia severity compared to waitlist controls.
Effect size was large (d = 1.55; P < .001)
Measured using the Insomnia Severity Index validated instrument
Intervention was a 4-week digital circadian-based sleep program
This was the largest effect size observed across all outcomes
Results
Resilience scores improved modestly in the intervention group but the difference was not statistically significant.
Effect size was small-to-medium (d = 0.4; P = .15)
Measured using the Brief Resilience Scale
Authors noted 'trends suggest potential benefit and warrant further study in larger, longer-term trials'
The non-significant result may reflect limited statistical power in this pilot study
Results
The digital sleep intervention demonstrated high feasibility and acceptability among nurse leaders.
Completion rate was 97.5% (39 of 40 participants)
Participant satisfaction mean score was 3.51 out of 5
Participants reported the app was easy to use
Engagement and qualitative feedback were collected alongside quantitative measures
Methods
The study enrolled 40 nurse leaders in a randomized, waitlist-controlled pilot design targeting a population at high risk for sleep and burnout problems.
Nurse leaders experience high levels of stress, fatigue, and burnout often worsened by poor sleep quality and circadian disruption
Participants were assessed at baseline and at 4 weeks
Validated measures included the PROMIS Sleep Disturbance 8b, Insomnia Severity Index, and Brief Resilience Scale
The intervention was described as a 'digital circadian-based sleep intervention'
What This Means
This research suggests that a smartphone-based sleep improvement app can meaningfully help nurse leaders sleep better. In a small randomized study of 40 nurse leaders, those who used the app for four weeks showed large improvements in both overall sleep quality and insomnia symptoms compared to a control group that was placed on a waitlist. Nearly all participants (97.5%) completed the study, and most found the app easy to use, suggesting this type of tool is practical for a busy healthcare leadership population.
The app was designed around circadian science — meaning it worked with the body's natural internal clock to optimize sleep timing and quality. The improvements seen were not just statistically significant but also clinically meaningful, with effect sizes considered large by research standards. There was also a trend toward improved resilience (the ability to bounce back from stress) among app users, though this finding was not statistically significant, possibly because the study was too small to detect a more modest effect.
This research matters because nurse leaders are particularly vulnerable to burnout and fatigue, which can affect both their own health and the quality of care they oversee. This study suggests that accessible digital tools targeting sleep could be a low-barrier way to support well-being in this workforce. The authors call for larger, longer-term studies to confirm these findings and to better understand whether sleep improvements translate into lasting gains in resilience and overall well-being.
