Interpersonally-Based Fears and Feelings During the Covid-19 Pandemic Revisited: Research Findings and Further Reflections on Fear of Missing out and Feelings of not Mattering.

Much has transpired since severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) began spreading throughout the world in 2020. In our previous commentary, we focused on the significance of two specific fears with an interpersonal basis (i.e. the fear of missing out, FoMO, and the fear of not mattering) during a period in which daily routines were disrupted and physical distancing or "social distancing" was implemented as a crucial important public health intervention in response to the coronavirus. In the current article, we examine the current context and review what has been learned about the similarities and differences among people during the pandemic with a particular emphasis on research during the pandemic on the fear of missing and feelings and fears of not mattering to other people. The nature of these constructs as revealed during the pandemic is discussed with a focus on how these attributes reflect insecurity and doubts about the self that heighten susceptibility to external feedback. Key themes include the need to consider FoMO from a broad perspective that includes actual lost opportunities during the pandemic and how individual differences in mattering have been reflected in coping and adaptability and related outcomes. It is clear from our analysis that FoMO and mattering are highly salient and relevant constructs with clear ecological validity in terms of accounting for individual differences in the costs and consequences of the pandemic.
