Aims of this study were (a) to summarize the psychometric literature on the Mobility Inventory for Agoraphobia (MIA), (b) to examine the convergent and discriminant validity of the MIA's Avoidance Alone and Avoidance Accompanied rating scales relative to clinical severity ratings of anxiety disorders from the Anxiety Disorders Interview Schedule (ADIS), and (c) to establish a cutoff score indicative of interviewers' diagnosis of agoraphobia for the Avoidance Alone scale. A meta-analytic synthesis of 10 published studies yielded positive evidence for internal consistency and convergent and discriminant validity of the scales. Participants in the present study were 129 people with a diagnosis of panic disorder. Internal consistency was excellent for this sample, α=.95 for AAC and .96 for AAL. When the MIA scales were correlated with interviewer ratings, evidence for convergent and discriminant validity for AAL was strong (convergent r with agoraphobia severity ratings=.63 vs. discriminant rs of .10-.29 for other anxiety disorders) and more modest but still positive for AAC (.54 vs. .01-.37). Receiver operating curve analysis indicated that the optimal operating point for AAL as an indicator of ADIS agoraphobia diagnosis was 1.61, which yielded sensitivity of .87 and specificity of .73.
(a)总结《广场恐怖症移动性量表》（MIA）的心理测量文献；(b)检验 MIA 的回避单独和回避伴随评分量表与《焦虑障碍访谈量表》（ADIS）中焦虑障碍临床严重程度评定之间的聚合和区别效度；(c)为回避单独量表建立一个指示访谈者对广场恐怖症诊断的截断分数。对 10 项已发表研究的元分析综合表明，这些量表具有良好的内部一致性、聚合和区别效度。本研究的参与者是 129 名被诊断为恐慌症的人。该样本的内部一致性非常好，AAC 的 α 值为.95，AAL 的 α 值为.96。当 MIA 量表与访谈者的评定相关时，AAL 的聚合和区别效度的证据很强（与广场恐怖症严重程度评定的聚合相关系数为.63，与其他焦虑障碍的区分相关系数为.10-.29），AAC 的证据也很适度但仍然是阳性的（.54 与.01-.37）。受试者工作特征曲线分析表明，AAL 作为 ADIS 广场恐怖症诊断指标的最佳工作点为 1.61，其敏感性为.87，特异性为.73。
