Although the State-Trait Anxiety Inventory (STAI) is a popular measure of anxiety, some previous research suggests that the trait scale may assess depression, as well as anxiety. The factor structure of the trait items was initially examined using factor analytic procedures. Confirmatory factor analytic methods suggested that a hierarchical solution best fit the data, with one overall factor and two lower order factors. The lower order subscales created from this factor solution were examined in a sample of individuals diagnosed with an anxiety disorder. Overall, the results offered good support for the notion that the trait scale of the STAI assesses depression, as well as anxiety. One set of items appeared to assess anxiety and worry, whereas the other assessed sadness and self-deprecation. The two subscales correlated differentially with other measures of anxiety and depression in a manner that was consistent with their content. Finally, diagnostic groups and controls could be meaningfully distinguished on these subscales. Implications for the use of this measure are discussed.
尽管状态-特质焦虑量表（STAI）是一种常用的焦虑测量工具，但先前的一些研究表明，特质量表可能既评估焦虑，也评估抑郁。特质项目的因子结构最初使用因子分析程序进行了检验。验证性因子分析方法表明，层次模型最适合数据，有一个总体因子和两个低阶因子。从这个因子模型得出的低阶分量表在一组被诊断为焦虑症的个体样本中进行了检验。总体而言，结果有力地支持了STAI特质量表既评估焦虑也评估抑郁这一观点。一组项目似乎评估焦虑和担忧，而另一组评估悲伤和自我贬低。这两个分量表与其他焦虑和抑郁测量指标的相关性在方式上与其内容一致。最后，在这些分量表上可以有意义地区分诊断组和对照组。本文讨论了该测量工具使用方面的意义。
