The rapidly expanding empirical study of personality disorders is the result of the publication of operational diagnostic criteria in DSM-III and the development of instruments to assess these criteria. Few researchers have examined the comparability of measures of personality disorders, and to our knowledge there are no studies of the factors associated with discordance between measures. In the present study, 697 relatives of psychiatric patients and healthy controls were interviewed with the Structured Interview for Personality Disorders (SIDP) and completed the Personality Disorders Questionnaire (PDQ). Significantly more individuals had a personality disorder according to the SIDP; however, multiple personality disorders were more frequently diagnosed on the PDQ. Schizotypal, compulsive, dependent, and borderline personality disorders were significantly more frequently diagnosed by the PDQ, whereas the SIDP more frequently diagnosed antisocial and passive-aggressive personality disorder. The corresponding dimensional scores of the two measures were all significantly correlated; however, the concordance for categorical diagnoses was poor. Discrepancies between the PDQ and the SIPD dimensional scores were significantly associated with current level of depressive symptoms and PDQ lie scale scores.
人格障碍实证研究的迅速扩展是《精神疾病诊断与统计手册》第三版（DSM - III）中操作性诊断标准的发布以及评估这些标准的工具发展的结果。很少有研究者考察人格障碍测量方法的可比性，据我们所知，尚无关于测量方法之间不一致相关因素的研究。在本研究中，对697名精神病患者亲属和健康对照者进行了人格障碍结构化访谈（SIDP），并让他们完成了人格障碍问卷（PDQ）。根据SIDP，被诊断为人格障碍的个体显著更多；然而，PDQ更频繁地诊断出多种人格障碍。分裂型、强迫型、依赖型和边缘型人格障碍通过PDQ诊断的频率显著更高，而SIDP更频繁地诊断出反社会和被动攻击型人格障碍。两种测量方法的相应维度分数均显著相关；然而，分类诊断的一致性较差。PDQ和SIPD维度分数之间的差异与当前抑郁症状水平和PDQ说谎量表分数显著相关。
