The Role of Threat Level and Intolerance of Uncertainty (IU) in Anxiety: An Experimental Test of IU Theory
چکیده انگلیسی


- Evaluated relationships among uncertainty, threat, and anxiety.
- Utilized an ecologically valid in vivo speech-stressor task.
- IU predicted increased state anxiety during an uncertain threat.
- No significant differences in state anxiety among individuals elevated in IU when comparing uncertain versus certain threat.
- IU and certainty level did not interact to predict increased state anxiety.

Intolerance of uncertainty (IU) has been proposed as an important transdiagnostic variable within mood- and anxiety-related disorders. The extant literature has suggested that individuals high in IU interpret uncertainty more negatively. Furthermore, theoretical models of IU posit that those elevated in IU may experience an uncertain threat as more anxiety provoking than a certain threat. However, no research to date has experimentally manipulated the certainty of an impending threat while utilizing an in vivo stressor. In the current study, undergraduate participants (N = 79) were randomized to one of two conditions: certain threat (participants were told that later on in the study they would give a 3-minute speech) or uncertain threat (participants were told that later on in the study they would flip a coin to determine whether or not they would give a 3-minute speech). Participants also completed self-report questionnaires measuring their baseline state anxiety, baseline trait IU, and prespeech state anxiety. Results indicated that trait IU was associated with greater state anticipatory anxiety when the prospect of giving a speech was made uncertain (i.e., uncertain condition). Further, findings indicated no significant difference in anticipatory state anxiety among individuals high in IU when comparing an uncertain versus certain threat (i.e., uncertain and certain threat conditions, respectively). Furthermore, results found no significant interaction between condition and trait IU when predicting state anticipatory anxiety. This investigation is the first to test a crucial component of IU theory while utilizing an ecologically valid paradigm. Results of the present study are discussed in terms of theoretical models of IU and directions for future work.
