Abstract
The Fear of Missing Out (FoMO) is the sense that others are having a rewarding experience which one is absent from. Given that it is associated with the drive to remain socially connected, research has predominantly focused on the link between FoMO and social networking use. While a 10-item measure of FoMO is widely used (FoMOs), a shorter scale may be preferable in some circumstances and would allow FoMO to be measured in more diverse contexts. Therefore, we aimed to validate a FoMO short-form (consisting of a single item: "Do you experience FoMO?"). In Studies 1 to 3, we measured the concurrent validity of the FoMOsf with the 10-item FoMOs (Pearson's R correlation between the FoMOs and FoMOsf: Study 1r = .735,r = .654; Study 2r = .638; Study 3r = .807). In Study 2, we measured the test-retest reliability of the FoMOsf (r = .717). In Study 2 and 3, we measured the construct validity of the FoMOsf by linking the FoMOsf to social networking use. The FoMOsf showed good concurrent validity, construct validity, and test-retest reliability and is adequate for use in research.
