Intolerance of Uncertainty Mediates the Influence of Viral Anxiety on Social Distancing Phobia Among the General Korean Population During the Coronavirus Disease 2019 Pandemic.

Abstract

Objective We aimed to examined the reliability and validity of Korean version of Social Distancing Phobia scale, and whether intolerance of uncertainty mediates the association of the general population’s social distancing phobia with viral anxiety and depression. Methods Through this anonymous online survey, we collected responses from 400 individuals in the general Korean population. Participants’ demographic information and rating scales scores, including the Social Distancing Phobia scale, Stress and Anxiety to Viral Epidemics-6 items, Patient Health Questionnaire-9, and Intolerance of Uncertainty-12 items. Results Confirmatory factor analysis showed a good model fit, and the Korean version of Social Distancing Phobia scale showed good internal consistency. Social distancing phobia was significantly correlated with age (r=0.213, p<0.001), viral anxiety (r=0.390, p<0.001), depression (r=0.244, p<0.001), and intolerance of uncertainty (r=0.323, p<0.001). A linear regression analysis showed that age (β=0.235, p<0.001), viral anxiety (β=0.281, p<0.001), depression (β=0.121, p=0.009), and intolerance of uncertainty (β=0.200, p<0.001; adjusted R2=0.246, F=33.6, p<0.001) predicted social distancing phobia. Mediation analysis revealed that viral anxiety directly influenced social distancing phobia (z=6.48, p<0.001), and intolerance of uncertainty partially mediated this association (z=2.92, p=0.003). Conclusion Social distancing phobia may cause psychological stress but may also increase adherence to physical distancing measures and prevent the spread of viruses.
