It is important to understand the mechanism through which FOMO influences sleepiness, self-regulation and aggression. Purpose: The objective of the study was to investigate the relationship between FOMO and aggression in young adults and examine the mediating roles of fatigue, daytime sleepiness and self-regulation in the relationship between FOMO and aggression. Method: A cross-sectional correlational research design was employed to collect data from 455 young adults aged 1824 years (M = 20.71; SD = 1.61). Data were collected through standardised self-report measures. The obtained data were analysed using the Statistical Package for the Social Sciences v23, and sequential mediation analysis using AMOS v22. Results: Findings indicated significant relationships between FOMO and the outcome variables like aggression, daytime sleepiness and self-regulation. However, no significant relationship was found between FOMO and fatigue; therefore, fatigue was not considered for further analysis. Sequential mediation analysis revealed that elevated levels of FOMO predicted lower daytime sleepiness (? = 0.26, p &lt; .001), which in turn predicted low self-regulation (? = 0.39, p &lt; .001) and consequently led to elevated levels of aggression (? = 0.26, p &lt; .001). The indirect route (FOMO ? sleepiness ? self-regulation ? aggression) was statistically significant with excellent model fit (?2(2) = 3.86, RMSEA = 0.02, CFI = 0.99, SRMR = 0.01). Conclusion: The study indicates a full sequential mediation: greater FOMO levels reduce daytime sleepiness, possibly due to heightened arousal, which in turn leads to poor self-regulatory skills and increased aggression. It can be concluded that psychological interventions to improve self-regulation can help manage aggression in people with high levels of FOMO. The Author(s) 2026.
