حساسیت اضطرابی و عدم تحمل عدم قطعیت به ترتیب به عنوان آسیب پذیری خاص برای اضطراب اجتماعی و افسردگی در یک مدل سلسله مراتبی عمل می کنند

Within a hierarchical framework for depressive and anxiety disorders, negative affect (NA) is posited to be indirectly related to social anxiety and depression through cognitive vulnerabilities, including intolerance of uncertainty (IU) and anxiety sensitivity (AS). However, few prior studies have considered whether the lower-order dimensions of IU (i.e., prospective and inhibitory IU) and AS (i.e., physical, cognitive, and social concerns) better explain the indirect relation between NA and social anxiety and depression. The indirect relations between NA and social anxiety and depression through these cognitive vulnerabilities were examined using structural equation modeling in a clinical sample (N = 298). NA and social anxiety symptoms were indirectly related through AS social concerns and inhibitory IU, although a direct effect of NA was also found. Only AS social concerns explained the relation between NA and a social anxiety disorder diagnosis. AS cognitive concerns was the only cognitive vulnerability factor to indirectly explain the relation between NA and depressive symptoms, although a direct effect of NA was also found. These findings suggest that the lower-order dimensions of AS and IU demonstrate more specific and less transdiagnostic associations with social anxiety and depression.
