The reliability and validity of the Toronto Structured Interview for Alexithymia (TSIA) have been demonstrated in previous studies with English-speaking community and psychiatric samples and a German-speaking psychiatric sample. The aim of this study was to evaluate the psychometric properties of the TSIA in a mixed clinical and nonclinical sample from Italy. The original English version of the TSIA was translated into Italian and administered, along with the 20-item Toronto Alexithymia Scale (TAS-20), to 80 healthy subjects, 69 medical outpatients, and 62 psychiatric outpatients. Eighty-one videotaped interviews were used for assessing the interrater reliability. Confirmatory factor analysis supported the hierarchical, four-factor structure of the TSIA obtained in previous studies, with four lower-order factors nested within two higher-order latent factors. The TSIA also demonstrated internal and interrater reliability, and concurrent validity with the TAS-20. The results support the use of the TSIA to assess alexithymia especially when a multimethod approach to measurement is possible.
多伦多述情障碍量表（TSIA）的可靠性和有效性已在前瞻性研究中得到验证，研究对象包括英语为母语的社区和精神科样本，以及德语为母语的精神科样本。本研究旨在评估 TSIA 在意大利混合临床和非临床样本中的心理测量特性。TSIA 的原始英文版本被翻译成意大利语，并与 20 项多伦多述情障碍量表（TAS-20）一起用于评估 80 名健康受试者、69 名门诊患者和 62 名精神科门诊患者。81 个录像访谈用于评估评定者间信度。验证性因子分析支持了在先前研究中获得的 TSIA 的分层、四因素结构，四个较低阶的因素嵌套在两个高阶的潜在因素中。TSIA 还表现出内部和评定者间信度，以及与 TAS-20 的同时效度。结果支持使用 TSIA 评估述情障碍，特别是在可以采用多方法测量的情况下。
