Validation of the Thai Version of the Fear of Missing Out Scale (T-FoMOs) for Adolescents: A Psychometric Analysis
Main Article Content
Abstract
With the rise of social media, which offers constant opportunities for interaction, academic interest has increasingly turned toward the concept of Fear of Missing Out (FoMO). FoMO is defined as a pervasive concern that others might be experiencing rewarding events from which one is absent. Despite the growing academic interest, no instrument has been developed to measure FoMO among Thai adolescents in empirical studies. The primary aim of this study was to validate and assess the psychometric properties of the Thai version of the Fear of Missing Out scale (T-FoMOs) for adolescents by adapting the original English version.
The results indicated that the scale demonstrated good internal consistency, with a Cronbach’s alpha coefficient of 0.80 for the total scale, based on data from 340 Thai adolescent students (Mage = 15.24, SD = 1.80). Exploratory factor analysis (EFA) revealed a two-factor structure, labeled “Behavioral” (α = 0.77) and “Psychological” (α = 0.76), which differs from the original scale’s single-factor model, accounting for 52.40% of the total variance. Confirmatory factor analysis (CFA: CMIN/df = 2.14, GFI = 0.95, RMSEA = 0.08, CFI = 0.91, NFI = 0.85, PNFI = 0.64, and TLI = 0.88) supported the construct validity of the scale. These findings suggest that the T-FoMOs is a reliable tool for assessing FoMO among Thai adolescents.
