Screening for social anxiety disorder with the self-report version of the Liebowitz Social Anxiety Scale

OBJECTIVE: This study examined whether the self-report version of the Liebowitz Social Anxiety Scale (LSAS-SR) could accurately identify individuals with social anxiety disorder and individuals with the generalized subtype of social anxiety disorder. Furthermore, the study sought to determine the optimal cutoffs for the LSAS-SR for identifying patients with social anxiety disorder and its generalized subtype. METHODS: Two hundred and ninety-one patients with clinician-assessed social anxiety disorder (240 with generalized social anxiety disorder) and 53 control participants who were free from current Axis-1 disorders completed the LSAS-SR. RESULTS: Receiver Operating Characteristic analyses revealed that the LSAS-SR performed well in identifying participants with social anxiety disorder and generalized social anxiety disorder. Consistent with Mennin et al.'s [2002: J Anxiety Disord 16:661-673] research on the clinician-administered version of the LSAS, cutoffs of 30 and 60 on the LSAS-SR provided the best balance of sensitivity and specificity for classifying participants with social anxiety and generalized social anxiety disorder, respectively. CONCLUSIONS: The LSAS-SR may be an accurate and cost-effective way to identify and subtype patients with social anxiety disorder, which could help increase the percentage of people who receive appropriate treatment for this debilitating disorder.
