The intolerance of uncertainty model of worry posits that individuals worry as a means to cope with the discomfort they feel when outcomes are uncertain, but few experimental studies have investigated the causal relationships between intolerance of uncertainty, situational uncertainty, and state worry. Furthermore, existing studies have failed to control for the likelihood of future negative events occurring, introducing an important rival hypothesis to explain past findings. In the present study, we examined how individuals with high and low trait intolerance of uncertainty differ in their behavioral, cognitive, and emotional reactions to situational uncertainty about an upcoming negative event (watching emotionally upsetting film clips), holding constant the likelihood of that negative event taking place. We found that although individuals high in trait prospective intolerance of uncertainty reported a higher degree of belief that being provided with detailed information about the upcoming stressor would make them feel more at ease, they did not experience an actual decrease in distress or state worry upon being provided with more information, during anticipation of the film clips, or during the film clips themselves. Our results suggest that h...
