The present investigation was designed to determine by factor analysis the nature of the items that comprise the A-State and A-Trait scales of the State-Trait Anxiety Inventory. Three factors were identified. Factor I was defined exclusively by items from the A-State scale. The underlying dimension tapped by the scale was interpreted as state anxiety (how one feels at a particular moment in time); support thus was provided for Spielberger's A-State concept. Items from the A-Trait scale, however, identified two separate factors, neither of which was clearly consonant with Spielberger's concept of A-Trait. Factor II appeared to tap state anxiety according to how the individual generally feels or a typical level of state anxiety as remembered over an indefinite period of time. Factor III was interpreted as a measure of neuroticism.
本研究旨在通过因素分析确定构成状态-特质焦虑量表中A状态和A特质分量表的项目的性质。识别出了三个因素。因素I完全由A状态分量表中的项目定义。该量表所挖掘的潜在维度被解释为状态焦虑（一个人在特定时刻的感受）；因此为斯皮尔伯格的A状态概念提供了支持。然而，A特质分量表中的项目识别出了两个独立的因素，其中任何一个都与斯皮尔伯格的A特质概念不完全一致。因素II似乎根据个体的总体感受或在不确定时间段内记忆的典型状态焦虑水平来挖掘状态焦虑。因素III被解释为神经质的一种度量。
