WHAT IS KNOWN ON THE SUBJECT?: The TAS-20 is the most widely used self-reported questionnaire to assess the level of alexithymia in students and community and clinical samples. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: The TAS-20-C exhibited high levels of reliability and validity, indicating that it is appropriate for the assessment of alexithymia in Chinese adolescents. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Screening adolescents who are at risk of alexithymia through the TAS-20 could help to perform necessary and effective precautions to decrease the adverse effects of alexithymia, such as the risks of developing depressive mood and behavioral problems.
Purpose The aim of this study was to examine the psychometric properties of the Chinese version of the 20-item Toronto Alexithymia Scale (TAS-20-C) in a sample of Chinese adolescents. Method Adolescents (n = 1260) recruited from three schools in mainland China completed the TAS-20-C, the somatization subscale of the Symptom Checklist 90 (SCL-90) and Center for Epidemiological Studies Depression Scale (CES-D). Five different factorial models of the TAS-20 were tested using confirmatory factor analysis (CFA). Cronbach's α, mean inter-item correlations and predictive validity were also evaluated. Results Among those five different factorial models, the four-factor structure model was suitable and invariant across gender and age in this sample. The TAS-20-C demonstrated adequate internal reliability. Gender and age accounted for insignificant amounts of variability in total TAS-20-C and factor scores. TAS-20-C total and subscale scores were correlated significantly with SCL-90 somatization subscale and CES-D. Girls scored higher than boys on difficulty identifying feelings (DIF) and pragmatic thinking (PR) subscales. DIF and lack of subjective significance or importance of emotions (IMs) subscale scores were higher among younger than among middle and older adolescents. Implications for Practice Validating the TAS-20 in adolescents is quite important to use it in evaluating adolescents' alexithymia, and screen those at risk of alexithymia.
关于该主题已知的信息是什么？：多伦多述情障碍量表（TAS-20）是用于评估学生、社区及临床样本中述情障碍水平的最广泛使用的自陈问卷。本文对现有知识的补充是什么？：中文版TAS-20（TAS-20-C）表现出高信度和效度，表明其适用于评估中国青少年的述情障碍。对实践有何启示？：通过TAS-20筛查有述情障碍风险的青少年有助于采取必要且有效的预防措施，以减少述情障碍的不良影响，如出现抑郁情绪和行为问题的风险。
目的 本研究旨在检验中文版20项多伦多述情障碍量表（TAS-20-C）在一组中国青少年样本中的心理测量学特性。方法 从中国大陆三所学校招募的青少年（n = 1260）完成了TAS-20-C、症状自评量表90（SCL-90）的躯体化分量表和流调中心抑郁量表（CES-D）。使用验证性因子分析（CFA）对TAS-20的五种不同因子模型进行了检验。还评估了克朗巴哈α系数、平均项目间相关性和预测效度。结果 在这五种不同的因子模型中，四因子结构模型在此样本中适合且在性别和年龄上具有不变性。TAS-20-C表现出足够的内部信度。性别和年龄在TAS-20-C总分及因子得分中所解释的变异量不显著。TAS-20-C总分及分量表得分与SCL-90躯体化分量表和CES-D显著相关。女孩在难以识别情感（DIF）和实用思维（PR）分量表上的得分高于男孩。在较年轻青少年中，DIF和缺乏情感主观意义或重要性（IMs）分量表得分高于中年和年长青少年。对实践的启示 在青少年中验证TAS-20对于使用其评估青少年述情障碍并筛查有述情障碍风险的个体非常重要。
