ABSTRACT
The primary objective was to assess the degree to which intolerance of uncertainty accounts for the association between negative urgency and anxiety and worry. The sample included 389 American college students from a state college in the Northeastern United States. Hayes' PROCESS v4.1 (2022) macro was used to investigate the mediating effects of intolerance of uncertainty on the relationship between negative urgency and worry and anxiety. A direct effect of negative urgency on worry was found and a mediating effect of intolerance of uncertainty was observed. A direct effect of negative urgency on state anxiety was found, and a mediating effect of intolerance of uncertainty was observed. The study advances support for the mediatory role of intolerance of uncertainty between negative urgency and anxiety and worry in American college students.
