Abstract

Recently, there has been a growing interest in intolerance of uncertainty (IU) as a transdiagnostic risk factor for various men tal disorders. However, no consensus has been reached on the components that comprise IU. Considering that while the rela tionship between IU and internalizing symptoms such as anxiety and depression has been well-established, a dearth of stud ies elucidates how each IU component is specifically related to anxiety and depression. Given its close relationship to internal izing symptoms, understanding the distinct correlations between each IU facet and internalizing symptoms becomes pivotal for effective interventions. Therefore, this study conducted a network analysis to delineate IU structure and how each compo nent is related to state/trait anxiety and depression. Using the Intolerance of Uncertainty Scale (IUS), the most central item, structure, and relationship within the scale were identified. The relationship between IU and internalizing symptoms was also examined and the clinical implications of each result are discussed.
