There is a movement towards a dimensional classification of personality disorders (PD). However, data linking dimensional systems and the categorical system for classifying PD are lacking. In the present study, N = 165 normal subjects and N = 222 nonpsychotic in-patients (including N = 81 patients with a PD diagnosis) completed the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ) measuring 18 PD traits. DSM-IV PD symptoms were assessed by SCID-II interviews. Group differences were analyzed by ANCOVA, and the relation between the dimensional and categorical approach was investigated by regression, ROC, and MDS analyses. Patients with PD exhibited elevated scores on all DAPP traits compared with controls. Patients without PD scored in between. Each DSM-IV PD could be described by a distinct profile of DAPP traits. Results support the assumption that the DAPP trait system can represent mean differences between clinically defined subgroups. The categorical system can be mapped onto the dimensional DAPP system with sufficient clinical specificity.
目前有一种人格障碍（PD）的维度分类趋势。然而，缺乏将维度系统与用于分类 PD 的分类系统联系起来的数据。在本研究中，N=165 名正常受试者和 N=222 名非精神病住院患者（包括 81 名 PD 诊断患者）完成了测量 18 种 PD 特征的人格病理学的维度评估-基础问卷（DAPP-BQ）。DSM-IV PD 症状通过 SCID-II 访谈进行评估。通过协方差分析（ANCOVA）分析组间差异，并通过回归、ROC 和 MDS 分析研究维度和分类方法之间的关系。与对照组相比，PD 患者在所有 DAPP 特征上的得分均升高。非 PD 患者的得分则处于两者之间。每个 DSM-IV PD 都可以通过 DAPP 特征的独特特征来描述。结果支持这样的假设，即 DAPP 特征系统可以代表临床定义的亚组之间的平均差异。分类系统可以以足够的临床特异性映射到维度 DAPP 系统上。
