Psychometric Properties and Measurement Invariance of The Fear of Missing Out Scale (FoMOs) In Chilean University Students

Abstract

Introduction: Social networks can harm university students' mental health; therefore, it is urgent to have valid instruments to measure new phenomena such as FoMO. 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 con-firmatory 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.
