Factor analytic studies of the State-Trait Anxiety Inventory (STAI) have provided support for the concepts of state and trait anxiety. This article reports the factor structure of the STAI (Form X) using 205 panic-disordered patients with and without agoraphobia. Results show that a two-factor oblique solution is the most appropriate, accounting for 41.1 per cent of the variance. Eighteen of the A-State items had salient loadings on factor 1 (state anxiety) and all 20 of the A-Trait items had salient loadings on factor 2 (trait anxiety). This study demonstrates the utility of the STAI in measuring anxiety in clinical populations and further supports the theoretical distinction between state and trait anxiety.
对状态-特质焦虑量表（STAI）的因素分析研究为状态焦虑和特质焦虑的概念提供了支持。本文报告了使用205名有或无广场恐惧症的惊恐障碍患者的STAI（X型）的因素结构。结果表明，两因素斜交解法是最合适的，解释了41.1%的方差。18个A-状态项目在因素1（状态焦虑）上有显著载荷，所有20个A-特质项目在因素2（特质焦虑）上有显著载荷。本研究证明了STAI在测量临床人群焦虑方面的效用，并进一步支持了状态焦虑和特质焦虑之间的理论区别。
