Two studies are reported describing the development of a short-form of the state scale of the Spielberger State-Trait Anxiety Inventory (STAI) for use in circumstances where the full-form is inappropriate. Using item-remainder correlations, the most highly correlated anxiety-present and anxiety-absent items were combined, and correlated with scores obtained using the full-form of the STAI. Correlation coefficients greater than .90 were obtained using four and six items from the STAI. Acceptable reliability and validity were obtained using six items. The use of this six-item short-form produced scores similar to those obtained using the full-form. This was so for several groups of subjects manifesting a range of anxiety levels. This short-form of the STAI is therefore sensitive to fluctuations in state anxiety. When compared with the full-form of the STAI, the six-item version offers a briefer and just as acceptable scale for subjects while maintaining results that are comparable to those obtained using the full-form of the STAI.
本文报告了两项研究，描述了斯皮尔伯格状态-特质焦虑量表（STAI）状态分量表简版的开发情况，该简版用于完整版不适用的情况。通过项目-剩余相关分析，将相关性最高的焦虑存在和焦虑不存在项目进行组合，并与使用STAI完整版获得的分数进行相关分析。从STAI中选取4个和6个项目时，相关系数大于0.90。使用6个项目时获得了可接受的信度和效度。使用这个6项简版得出的分数与使用完整版得出的分数相似。对于几组表现出不同焦虑水平的受试者都是如此。因此，STAI的这个简版对状态焦虑的波动很敏感。与STAI完整版相比，6项版本为受试者提供了一个更简短且同样可接受的量表，同时保持了与使用STAI完整版获得的结果相当的结果。
