人格障碍的结构的主要批评之一是建立在实证研究进行因素分析的标准为每一个障碍。这里的研究人员着眼于类别的区分效度，或者换句话说，他们询问类别之间是否存在真正的显著差异。研究如克拉克，Livesley和莫雷（1997）在他们的资料，显示该类别的判别效度往往是低。同样，同样的怀疑主义在各级DSM的类别，包括三组人格障碍。人格障碍的聚类可能表明，集群内的紊乱之间有一定的共性，因此，可能有一些模糊的区别。哥斯达黎加和widiger（1994）报告在对人格障碍的症状因子分析以前的证据和发现事实上有四个独立的集群的障碍的理由（Hyler Lyons，1988）而不是三个轴在临床上这一行的经验证据指出认为人格障碍也许，真的，只是假设的结构，而不是实体类。

One of the main criticisms of the construct of personality disorders is built on empirical studies carrying out factor analysis of the criteria for each disorder. Researchers here are looking at the discriminant validity of the categories, or in other words, they are asking whether there is really any significant difference between the categories. Research such as Clark, Livesley & Morey (1997) in their review of the data, have shown that the discriminant validity of the categories is often low. Similarly, the same kind of scepticism operates at all levels of the DSM categories, including the three clusters of personality disorders. The clustering of the personality disorders might suggest that there is some commonality between the disorder within the clusters, and therefore, there may be some blurring of the distinctions. Costa & Widiger (1994) report on previous evidence of factor analysis of the symptoms of the personality disorders and found that in fact there was justification for four separate clusters of disorders (Hyler & Lyons, 1988) instead of the three axes in the DSM-IV. This is one line of empirical evidence that points to the idea that personality disorders may, indeed, be mere hypothetical constructs, rather than solid categories.
