OBJECTIVE
Psychometric properties of 20-item Toronto Alexithymia Scale (TAS-20) have been widely analyzed, but the validity and psychometric qualities of the TAS-20 in populations with personality disorders are still poorly understood. The aim of the current study was to analyze the factor structure and validity of TAS-20.
METHOD
Data were extracted from a multisite clinical sample of patients with personality disorders or personality-related problems referred to specialist mental health services in Norway.
RESULTS
With one exception, TAS-20 revealed acceptable psychometric properties. Variations of TAS-20 are associated with other clinical measures of distress and severity. Anxiety disorders, borderline, and avoidant personality disorders were all highly related to levels of TAS-20. The TAS-20 also revealed unique variance not accounted for by subjective distress, symptom disorders, or dysfunctional personality traits.
CONCLUSION
The TAS-20 is a relevant instrument for use in assessment of personality disorders, but one subscale should be improved.
目的
多伦多述情障碍量表（TAS-20）的 20 项心理测量特性已得到广泛分析，但述情障碍量表在人格障碍人群中的效度和心理测量特性仍知之甚少。本研究旨在分析 TAS-20 的因子结构和效度。
方法
数据来自挪威专门心理健康服务机构转诊的人格障碍或与人格相关问题的多地点临床样本。
结果
除一项外，TAS-20 均显示出可接受的心理测量特性。TAS-20 的变化与其他痛苦和严重程度的临床测量指标相关。焦虑障碍、边缘型和回避型人格障碍均与 TAS-20 的水平高度相关。TAS-20 还显示出无法用主观痛苦、症状障碍或功能失调的人格特征来解释的独特差异。
结论
TAS-20 是评估人格障碍的一个相关工具，但一个分量表需要改进。
