Social anxiety and negative interpretations of positive social events: What role does intolerance of uncertainty play?

Abstract Objective Although previous studies have demonstrated the association between social anxiety symptom severity and the tendency to appraise positive social events negatively among individuals with social anxiety disorder, no study has examined mediators of this relationship. The current study sought to examine whether intolerance of uncertainty and its subfactors mediate the relationship between social interaction anxiety and the tendency to interpret positive social events negatively. Method One hundred and sixty‐five individuals with social anxiety disorder completed measures of social interaction anxiety symptom severity, intolerance of uncertainty, and negative interpretations of positive social events. Results Total intolerance of uncertainty and the inhibitory‐intolerance of uncertainty subscale scores significantly mediated the relationship between social interaction anxiety and negative interpretations of positive events. Exploratory post‐hoc analyses regarding the possible contributing role of depression demonstrated mixed results. The same mediation pattern was found in the full sample as well as those without a secondary comorbid mood disorder diagnosis. In contrast, serial mediation showed a mediating role of depressive symptom severity. Conclusion Inhibitory‐intolerance of uncertainty plays a role in the relationship between social interaction anxiety and negative interpretations of positive social events.
