Psychometric characteristics of the Mobility Inventory (MI) were examined in 216 outpatients diagnosed with panic disorder with agoraphobia participating in a longitudinal study of anxiety disorders. An exploratory principal components analysis replicated a three-component solution for the MI reported in prior studies, with components corresponding to avoidance of public spaces, avoidance of enclosed spaces, and avoidance of open spaces. Correlational analyses suggested that the components tap unique but related areas of avoidance that were remarkably stable across periods of 1, 3, and 5 years between administrations. Implications of these results for future studies of agoraphobia are discussed.
在一项针对焦虑症的纵向研究中，对216名被诊断为伴有广场恐惧症的惊恐障碍门诊患者的行动能力量表（MI）的心理测量特征进行了检查。探索性主成分分析重复了先前研究中报告的MI的三成分解决方案，这些成分分别对应于对公共场所的回避、对封闭空间的回避和对开放空间的回避。相关性分析表明，这些成分反映了独特但相关的回避领域，在两次施测之间的1年、3年和5年期间，这些领域非常稳定。讨论了这些结果对未来广场恐惧症研究的意义。
