Systematic Review and Meta-Analysis of Correlation Coefficients Between Fear of Missing Out and Sleep Health...

Objective: To examine the association between Fear of Missing Out (FoMO) and dimensions of sleep health. Methods: We searched PubMed, PsycINFO, and Web of Science from inception to March 2025. Primary inclusion criteria were original studies reporting associations between FoMO and any sleep health dimension. Risk of bias in included studies was assessed independently by two reviewers using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist. Correlations between FoMO and sleep health dimensions were synthesized using random-effects meta-analytic models. Results: Twenty-two studies (25 independent samples; N = 12,191 participants) were included. Most used survey methods and assessed FoMO with the Fear of Missing Out Scale. Meta-analytic random-effects models were conducted for each sleep health dimension with at least 3 independent results. Twelve studies showed a positive correlation between FoMO and Sleep Quality (Fisher's Z = 0.265; p < 0.05), four studies showed a positive correlation between FoMO and Bedtime Procrastination (Fisher's Z = 0.231; p < .001), and five studies showed a positive correlation between FoMO and worse Sleep Hygiene (Fisher's Z = 0.268; p < .001). Two or fewer independent samples showed positive significant relations between FoMO and insomnia, later lights out time, problematic sleep, sleep deprivation, sleep onset latency, and sleep duration. Discussion: Preliminary evidence suggests FoMO is associated with multiple dimensions of sleep health. Further longitudinal studies using multidimensional sleep assessments are needed.
