Recent theories of generalized anxiety disorder (GAD) have emphasized interpersonal and personality functioning as important aspects of the disorder. We examined heterogeneity in interpersonal problems in 2 studies of individuals with GAD (n = 47 and n = 83). Interpersonal subtypes were assessed with the Inventory of Interpersonal Problems-Circumplex (Alden, Wiggins, & Pincus, 1990). Across both studies, individuals with GAD exhibited heterogeneous interpersonal problems, and cluster analyses of these patients' interpersonal characteristics yielded 4 replicable clusters, identified as intrusive, exploitable, cold, and nonassertive subtypes. Consistent with our pathoplasticity hypotheses, clusters did not differ with GAD severity, anxiety severity, or depression severity. Clusters in Study 2 differed on rates of personality disorders, including avoidant personality disorder, further providing support for the validity of interpersonal subtypes. The presence of interpersonal subtypes in GAD may have important implications for treatment planning and efficacy.
最近的广泛性焦虑障碍（GAD）理论强调人际关系和人格功能是该障碍的重要方面。我们在两项 GAD 患者的研究（n = 47 和 n = 83）中检查了人际关系问题的异质性。人际关系亚型使用人际关系问题清单-环面量表（Alden、Wiggins 和 Pincus，1990）进行评估。在两项研究中，GAD 患者表现出人际关系问题的异质性，对这些患者的人际关系特征进行聚类分析得出了 4 个可重复的聚类，分别确定为侵入性、剥削性、冷漠和非果断亚型。与我们的易病性假说一致，聚类与 GAD 严重程度、焦虑严重程度或抑郁严重程度没有差异。研究 2 中的聚类在人格障碍的发生率上存在差异，包括回避型人格障碍，进一步为人际关系亚型的有效性提供了支持。GAD 中存在人际关系亚型可能对治疗计划和疗效有重要影响。
