title: Comparison of anxiety-related traits between generalized and nongeneralized subtypes of social anxiety disorder.
abstract: This study aimed to investigate the possible difference in anxiety-related traits between the generalized and nongeneralized subtypes of social anxiety disorder (SAD). Two hundred seventy-three SAD Korean outpatients completed the Anxiety Sensitivity Index (ASI), the Trait Form of the State-Trait Anxiety Inventory (STAI-T), Retrospective Self-Report of Inhibition (RSRI), and the Liebowitz Social Anxiety Scale (LSAS) as part of their assessments. The unadjusted total scores of the ASI, STAI-T, RSRI, and LSAS differed between the two subtypes, according to an independent t-test. However, this result was not significant (ASI: F = 2.363, p = 0.127; STAI-T: F = 0.004, p = 0.949; RSRI: F = 1.518, p = 0.220) after adjusting for LSAS total score. The comparison of anxiety-related traits did not show any difference between the subtypes after adjusting for illness severity. These results may suggest that the two SAD subtypes are on a continuum of the same illness, differentiated only by symptom severity.
