The Liebowitz Social Anxiety Scale (LSAS) was the first evaluation instrument developed for screening for the signs and symptoms of Social Anxiety Disorder (SAD) and is currently still the most used worldwide. The aim of this study is to evaluate the ability of the LSAS - self-report version (LSAS-SR) to discriminate different Social Anxiety Disorder (SAD) clinical groups.
The sample was composed of Brazilians university students, allocated into three different groups, i.e., cases (C=118), non-cases (NC=95) and subclinical cases (SC=39). To achieve the aim, calculations of the ROC Curve and ANOVA were performed.
The results found were excellent regardless of the technique used, highlighting the discriminatory capacity of the LSAS-SR. The score equal to or greater than 32 is suggested as a cutoff score for the Brazilian population, since this presented balance between the standards evaluated and the ability to differentiate both clinical and subclinical SAD cases from non-cases.
Despite the specific sample used in this study being composed only of university students, the use of the LSAS-SR can be indicated, in the Brazilian setting, for SAD screening in both clinical and research contexts.
利博维茨社交焦虑量表（LSAS）是首个开发用于筛查社交焦虑障碍（SAD）体征和症状的评估工具，目前仍是全球使用最广泛的。本研究旨在评估LSAS自陈版（LSAS-SR）区分不同社交焦虑障碍（SAD）临床组别的能力。
样本由巴西大学生组成，分为三个不同组，即病例组（C = 118）、非病例组（NC = 95）和亚临床病例组（SC = 39）。为实现该目的，进行了ROC曲线计算和方差分析。
无论使用何种技术，所发现的结果都很出色，突出了LSAS-SR的鉴别能力。建议将等于或大于32分作为巴西人群的临界分数，因为这在评估标准与区分临床和亚临床SAD病例与非病例的能力之间呈现出平衡。
尽管本研究中使用的特定样本仅由大学生组成，但在巴西环境下，LSAS-SR可用于临床和研究背景下的SAD筛查。
