Domain-specific intolerance of uncertainty in socially anxious and contamination-focused obsessive-compulsive...

Intolerance of uncertainty (IU) has been increasingly recognized as a transdiagnostic factor across anxiety disorders and depression and is associated with substantial cognitive, behavioral, and emotional impairment. IU is typically construed as a dispositional tendency to view ambiguous stimuli and unknown outcomes as unacceptably threatening regardless of context, but recent findings suggest that the domain in which uncertainty is encountered may be relevant. Taking that research to the next step, the aim of the present study was to determine whether IU is more salient in concern-congruent versus incongruent domains and whether domain-specific IU is a better predictor of anxiety symptoms than trait IU. A total of 102 undergraduates were recruited into analog socially anxious (SA), obsessive-compulsive contamination (OCC), and nonanxious control (NAC) groups based on responses to measures of SA and OCC symptoms. Both groups reported more domain-congruent IU than trait IU or domain-incongruent IU. The SA group reported more social interaction IU than the OCC and NAC groups; the OCC group reported more cleanliness IU than the SA and NAC groups. Domain-specific IU predicted social anxiety and OCC fears above and beyond trait IU. Results suggest that IU has a substantial context-specific component and should be examined both transdiagnostically and transsituationally.
