Objective: this study aimed to examine the psychometric properties of the Fear of Missing Out Scale (FoMOs) in a sample of Chilean university students. Methods: confirmatory factor analyses (CFA) were carried out and estimated using the Weighted Leasts Square Means and Variance (WLSMV). Results: the FoMOs evaluation had an internal consistency of 0,863 (Cronbach’s Alpha). The confirmatory factor analysis (CFA) showed two factors and good indicators: CFI = 0,991, TLI = 0,987, and an RMSEA of 0,054. Conclusion: the FoMOs is a good instrument for measuring the fear of missing out in the Chilean University population.enFear of Missing OutFOMOPsychometric PropertiesUniversity StudentsArtículoCC BY 4.0 DEED Atribución 4.0 Internacional10.56294/saludcyt2023328
