Addressing certain problems with the compositional structure of the self-report Toronto Alexithymia Scale, this paper reports the development of a revised version of the scale as well as results from a preliminary series of studies evaluating its reliability and validity. The Revised Toronto Alexithymia Scale (TAS-R) demonstrated good internal consistency and a stable and replicable two-factor structure that is congruent with the two major dimensions of the alexithymia construct. Evidence of convergent and discriminant validity for the TAS-R was provided by correlations with measures of other constructs. Criterion validity was demonstrated by the ability of TAS-R scores to discriminate between behavioral medicine outpatients designated alexithymic and those designated non-alexithymic on the basis of clinical interview ratings. Normative data are provided for university student, normal adult, and psychiatric outpatient populations.
针对自陈式多伦多述情障碍量表在结构组成方面的某些问题，本文报告了该量表修订版的编制情况以及一系列初步研究评估其信效度的结果。修订版多伦多述情障碍量表（TAS-R）显示出良好的内部一致性以及稳定且可重复的双因素结构，这与述情障碍概念的两个主要维度相符。通过与其他构念测量指标的相关性，提供了TAS-R的聚合效度和区分效度的证据。TAS-R分数能够根据临床访谈评分区分行为医学门诊中被认定为述情障碍的患者和非述情障碍的患者，从而证明了其效标效度。文中还提供了大学生、正常成年人和精神科门诊患者群体的常模数据。
