This study describes a psychometric approach to refining descriptions of antisocial, borderline, histrionic, and narcissistic personality disorders in an attempt to achieve greater distinctiveness. We developed descriptions of each diagnosis from content analysis of the literature. Psychiatrists' ratings were used to organize the features of each diagnosis into a set of carefully defined behavioral dimensions. Self-report scales were developed to assess each dimension. Scales were administered to a general population sample (N = 274) and a sample of patients with a primary diagnosis of personality disorder (N = 133). Scales demonstrated satisfactory levels of internal consistency. Some dimensions showed a low correlation with other dimensions defining the same diagnosis. These dimensions could be eliminated without affecting reliability. The structure underlying the dimensions delineating each diagnosis was evaluated using factor analysis. For each diagnosis, the structure was highly similar in the two samples. Based on these results, specific proposals are made for redefining diagnoses.
本研究描述了一种心理测量方法，用于细化对反社会型、边缘型、表演型和自恋型人格障碍的描述，以试图实现更大的区分度。我们通过对文献的内容分析得出了每种诊断的描述。利用精神科医生的评分，将每种诊断的特征组织成一组精心定义的行为维度。开发了自我报告量表来评估每个维度。量表施用于普通人群样本（N = 274）和原发性人格障碍患者样本（N = 133）。量表显示出令人满意的内部一致性水平。一些维度与定义相同诊断的其他维度相关性较低。这些维度可以在不影响信度的情况下被剔除。使用因子分析评估描绘每种诊断的维度背后的结构。对于每种诊断，两个样本中的结构高度相似。基于这些结果，提出了重新定义诊断的具体建议。
