Urgency and affective lability are two vulnerabilities that have been linked to posttraumatic stress disorder (PTSD). Urgency refers to rash action when experiencing intense positive or negative affect, whereas affective lability is the tendency to shift rapidly between emotion states. Although individuals high in urgency and affective lability may be more likely to engage in behaviors often exhibited by individuals with PTSD (e.g., substance use, risky behaviors), the extent to which urgency and affective lability interact to impact PTSD symptoms has yet to be examined. The current study hypothesized that the association between urgency (negative and positive) and PTSD symptoms would be stronger among those reporting elevated affective lability. Participants included 232 trauma-exposed college students who completed a series of questionnaires. Among individuals low in affective lability, both positive and negative urgency were positively associated with PTSD symptoms. Contrary to hypotheses, among those high in affective lability, positive and negative urgency were not associated with PTSD symptoms. Models with dimensions of affective lability were also examined. Findings suggest that the association between urgency and PTSD symptoms may only emerge among individuals who do not already possess the vulnerability associated with higher affective lability.
