The present study provides data on the reliability, validity and treatment sensitivity of the Liebowitz Social Anxiety Scale (LSAS), one of the most commonly used clinician-administered scales for the assessment of social phobia.
Three hundred and eighty-two patients from several studies of the treatment of social phobia were evaluated. An independent assessor administered the LSAS to each patient prior to the initiation of treatment. Patients also completed other measures of social anxiety and avoidance, although the specific measures varied across samples.
The LSAS and its subscales were normally distributed and demonstrated excellent internal consistency. The convergent validity of the LSAS was demonstrated via significant correlations with other commonly-used measures of social anxiety and avoidance. These correlations also tended to be larger than correlations with measures of depression, especially after treatment. However, the pattern of correlations of LSAS subscales with one another and with the other measures suggest that the fear subscales and the avoidance subscales may not be sufficiently distinct in clinical samples. The LSAS was also demonstrated to be sensitive to the effects of pharmacological treatments of social phobia over time and in comparison to double-blind pill placebo.
The LSAS appears to be a reliable, valid and treatment sensitive measure of social phobia. Further study of the LSAS, both in samples with severe social phobia and in community samples, is needed.
本研究提供了关于利博维茨社交焦虑量表（LSAS）的信度、效度和治疗敏感性的数据，该量表是临床医生评估社交恐惧症最常用的量表之一。
对来自多项社交恐惧症治疗研究的382名患者进行了评估。一名独立评估者在治疗开始前对每位患者进行了LSAS评估。患者还完成了其他社交焦虑和回避测量，尽管不同样本中的具体测量方法有所不同。
LSAS及其子量表呈正态分布，具有出色的内部一致性。通过与其他常用的社交焦虑和回避测量方法的显著相关性，证明了LSAS的收敛效度。这些相关性在治疗后也往往大于与抑郁测量方法的相关性。然而，LSAS子量表之间以及与其他测量方法的相关模式表明，在临床样本中，恐惧子量表和回避子量表可能没有足够的区别。LSAS还被证明对社交恐惧症药物治疗的效果随时间变化敏感，并且与双盲安慰剂相比也是如此。
LSAS似乎是一种可靠、有效且对治疗敏感的社交恐惧症测量方法。需要在严重社交恐惧症样本和社区样本中对LSAS进行进一步研究。
