Previous studies suggested an association of alexithymia with other personality models, as well as with various psychiatric syndromes. However, with regard to current diagnostic systems, the clinical validity of alexithymia remains to be established. In a sample of 182 psychiatric outpatients, the lifetime prevalence of DSM-III-R axis I disorders was determined by Structured Clinical Interview for DSM-III-R (SCID) interviews. In addition, DSM-III-R personality disorders were assessed using the Personality Diagnostic Questionnaire-Revised (PDQ-R). On the Toronto Alexithymia Scale (TAS), 17% of the sample scored in the alexithymic range. A series of stepwise multiple regression analyses were performed, exhibiting no relationship between alexithymia and any of the DSM-III-R axis I lifetime diagnoses. In contrast, schizotypal, dependent, and avoidant personality dimensions, as well as a lack of histrionic features, emerged as significant predictors of alexithymia, which further supports the conceptualization of alexithymia as a personality dimension.
先前的研究表明述情障碍与其他人格模型以及各种精神综合征有关联。然而，就当前的诊断系统而言，述情障碍的临床效度仍有待确定。在一个由182名精神科门诊患者组成的样本中，通过《精神障碍诊断与统计手册》第三版修订本（DSM-III-R）的结构化临床访谈（SCID）来确定DSM-III-R轴I障碍的终生患病率。此外，使用修订版人格诊断问卷（PDQ-R）对DSM-III-R人格障碍进行评估。在多伦多述情障碍量表（TAS）上，17%的样本得分处于述情障碍范围内。进行了一系列逐步多元回归分析，结果显示述情障碍与任何DSM-III-R轴I终生诊断之间均无关联。相比之下，分裂型、依赖型和回避型人格维度，以及缺乏表演型特征，成为述情障碍的显著预测因素，这进一步支持了将述情障碍概念化为一种人格维度的观点。
