Schizoid personality disorder (ScPD) is one of the "odd cluster" or "cluster A" personality disorders in DSM-IV. In the present article, the authors review information pertaining to the psychometric characteristics of ScPD as gleaned from a search of relevant publications as well as from databases of personality disorder study groups. Comparatively little evidence exists for the validity and reliability of ScPD as a separate, multifaceted personality disorder. Some authors, moreover, have contended that the group of patients termed "schizoid" actually fall into two distinct groups--an "affect constricted" group, who might better be subsumed within schizotypal personality disorder, and a "seclusive" group, who might better be subsumed within avoidant personality disorder. The research-based justification for retaining ScPD as an independent diagnosis is sufficiently sparse for it to seem reasonable to remove ScPD from the list of personality disorders in DSM-V, and instead to invite clinicians to code for schizoid traits using a dimensional model.
分裂型人格障碍（ScPD）是 DSM-IV 中的“古怪集群”或“集群 A”人格障碍之一。在本文中，作者通过对相关文献的检索以及人格障碍研究小组的数据库进行搜索，回顾了与 ScPD 的心理计量学特征相关的信息。作为一种独立的、多方面的人格障碍，ScPD 的有效性和可靠性的证据相对较少。此外，一些作者认为，被称为“分裂型”的患者群体实际上分为两个不同的群体——一个是“情感受限”群体，他们可能更好地归入分裂型人格障碍，另一个是“孤僻”群体，他们可能更好地归入回避型人格障碍。保留 ScPD 作为一个独立诊断的基于研究的理由是如此稀少，以至于将 ScPD 从 DSM-V 中的人格障碍列表中删除似乎是合理的，而不是邀请临床医生使用维度模型对分裂型特征进行编码。
