abstract="BACKGROUND AND OBJECTIVES: There is evidence that intolerance of uncertainty (IU) is associated with elevated post-traumatic stress (PTS) symptoms. There is a scarcity of research examining whether IU is prospectively related to PTS following exposure to negative life events. Using data from a Dutch student-sample, we examined the degree to which IU predicts post-traumatic stress symptoms associated with negative stressful life events (analogue posttraumatic stress (PTS)).<br><br>DESIGN: This was a prospective survey-study.<br><br>METHODS: A group of 193 undergraduate students completed self-report measures of Inhibitory IU, Prospective IU, and anxiety sensitivity (at Time 1, T1). One year later (at T2), participants rated adverse life-events experienced between T1 and T2, and completed a questionnaire tapping PTS associated with the most distressing event experienced in this time-frame. We hypothesized that pre-event Inhibitory IU and--to a lesser extent--Prospective IU would predict analogue PTS, after covarying for anxiety sensitivity.<br><br>RESULTS: As predicted, pre-event Inhibitory IU predicted post-event analogue PTS, even when controlling for anxiety sensitivity. With respect to distinct analogue PTS clusters, Inhibitory IU predicted PTS avoidance and PTS hyperarousal, but was unrelated to PTS reexperiencing.<br><br>CONCLUSIONS: This study confirm that IU, particularly Inhibitory IU, may convey risk for elevated PTS following adverse life events.<p /> <p>Language: en</p>",
