This self-report measure assesses anxiety and preoccupation related to the perception that others may be having rewarding experiences without one’s participation. The Fear of Missing Out Scale (FoMOs) was developed by Andrew K. Przybylski to quantify individual differences in fear of missing out and related social concerns.
The instrument consists of 10 items and typically requires about 2 minutes to complete. Responses are summed to yield an overall index of fear of missing out severity, which may be used in clinical screening, treatment planning, or research contexts where technology use and social comparison are relevant. The Fear of Missing Out Scale (FoMOs) is not diagnostic on its own and should be interpreted alongside clinical interview data and other validated measures.
