Intolerance of uncertainty (IU) has been associated with elevated post-traumatic stress symptoms (PTSS) in the extant literature. However, no research to date has investigated whether pre-trauma IU predicts PTSS following trauma exposure. The current study prospectively examined the relationship between IU and PTSS within a sample of individuals with various levels of exposure to a university campus shooting. We hypothesized that pre-trauma IU would predict elevated PTSS following a campus shooting, even after covarying for anxiety sensitivity (AS), a known correlate of PTSS. Participants included undergraduates (n = 77) who completed a self-report battery in Introductory Psychology. After a campus shooting, they were invited to complete measures of PTSD symptoms and level of exposure to the shooting. As anticipated, results revealed pre-trauma IU as a significant predictor of elevated PTSS following the campus shooting. These results remained significant after covarying for pre-trauma levels of AS. Our results are the first to demonstrate that elevated pre-trauma levels of IU predict later PTSS following exposure to a traumatic event. This finding is discussed in terms of promising directions for future research and treatment strategies. (C) 2016 Elsevier Ltd. All rights reserved.
