Using cluster analysis of 207 patients with panic disorder (PD), we investigated the relationships between several panic symptoms at the time of panic attacks, which included anticipatory anxiety, agoraphobia, and 13 clinical symptoms based on the Diagnostic and Statistics Manual-III-Revised. Cluster analysis revealed three panic symptom clusters: cluster A (dyspnea, choking, sweating, nausea, flushes/chills); cluster B (dizziness, palpitations, trembling or shaking, depersonalization, agoraphobia, and anticipatory anxiety); and cluster C (fear of dying, fear of going crazy, paresthesias, and chest pain or discomfort). Generally, cluster A was comprised exclusively of physiological symptoms, among which respiratory symptoms were prominent, cluster B included both panic and non-panic symptoms such as agoraphobia and anticipatory anxiety, and cluster C was comprised chiefly of fear symptoms.
通过对207名惊恐障碍（PD）患者进行聚类分析，我们研究了惊恐发作时几种惊恐症状之间的关系，这些症状包括预期焦虑、广场恐惧症以及基于《诊断与统计手册》第三版修订版的13种临床症状。聚类分析揭示了三个惊恐症状集群：集群A（呼吸困难、窒息感、出汗、恶心、脸红/发冷）；集群B（头晕、心悸、颤抖或摇晃、人格解体、广场恐惧症和预期焦虑）；以及集群C（怕死、怕发疯、感觉异常和胸痛或不适）。一般来说，集群A完全由生理症状组成，其中呼吸症状较为突出，集群B包括惊恐和非惊恐症状，如广场恐惧症和预期焦虑，而集群C主要由恐惧症状组成。
