"It's not just the judgements--It's that I don't know": intolerance of uncertainty as a predictor of social anxiety.
Interest in the role of intolerance of uncertainty (IU) - the tendency for a person to consider the possibility of a negative event occurring as unacceptable and threatening irrespective of the probability of its occurrence - in anxiety disorders has been increasing in recent research. IU has been implicated as an important construct associated with generalized anxiety disorder (GAD); however, a growing body of research suggests that levels of IU are also high among individuals with other anxiety disorders. Despite the increasing interest, few studies have examined the relationship between IU and social anxiety (SA). The purpose of the present investigation was to further investigate the relationship between IU and SA. Participants included 286 community members (71% women) from Canada who completed measures of IU, SA, anxiety sensitivity, and fear of negative evaluation (FNE). Regression analyses revealed that the inhibitory anxiety dimension of IU, the fear of socially observable anxiety symptoms dimension of anxiety sensitivity, and the FNE were consistently significant predictors of SA symptoms. Unexpectedly, IU and FNE were often comparable predictors of SA variance. Moreover, participants with SA symptoms consistent with SAD exhibited levels of IU comparable to those reported by participants with worry symptoms consistent with GAD. Comprehensive findings, implications, and directions for future research are discussed.
