ABSTRACT
Abstract Background: The aim of this study is to examine psychometric properties of the Turkish version of the fear of missing out scale (FoMOs) on three different study groups. Method: We conducted the construct validity of the Turkish FoMOs with confirmatory factor analysis, measurement invariance (study I; n = 354), and concurrent validity (study II; n = 371). We also evaluated the reliability of the Turkish FoMOs (study III; n = 61) using test-retest and Cronbach alpha reliability. Results: In study I, the confirmatory factor analysis revealed that the one-dimensional structure of the Turkish version of the FoMOs was verified. The results of measurement analysis depending on the sample of study I demonstrated that configural and metric invariances were established across Facebook and other social media users. The Cronbach alpha values calculated from the samples of study I (a = .79) and study II (a = .78) indicated that internal consistency of the scale was at the acceptable level. Lastly, test-retest reliability of the scale was found as .86 from the study III. Conclusion: Overall findings indicated that the psychometric properties of the Turkish version of FoMO scale were satisfactory to measure the FoMO in a wide range of ages in the Turkish context.
