The Fear of Missing Out Scale (FoMO; Przybylski, Murayama, DeHaan, & Gladwell, 2013) is a 10-item, single-factor measure โ one of the more straightforward write-ups in this series, because there's no subscale structure to explain.
The reliability line
Items are rated on a 5-point scale from not at all true of me to extremely true of me. In the original validation, the scale showed good internal consistency: ฮฑ = .87. Because it's unidimensional, you only need to report one alpha โ just be clear whether it's the original figure or your own sample's.
A sample paragraph
Fear of missing out was measured using the FoMO Scale (Przybylski et al., 2013), a 10-item unidimensional measure of the apprehension that others may be having rewarding experiences from which one is absent, rated on a 5-point scale from not at all true of me to extremely true of me. The scale demonstrated good internal consistency in the original validation (ฮฑ = .87).
If you're computing your own composite score, state your scoring method explicitly (mean vs. sum of the 10 items) โ the original paper doesn't fix one convention, so your reader shouldn't have to guess which you used.
