The aim of this review was to synthesise the literature on the use of the Toronto Alexithymia Scale (TAS) in eating disorder populations and Healthy Controls (HCs) and to compare TAS scores in these groups.
Electronic databases were searched systematically for studies using the TAS and meta-analyses were performed to statistically compare scores on the TAS between individuals with eating disorders and HCs.
Forty-eight studies using the TAS with both a clinical eating disorder group and HCs were identified. Of these, 44 were included in the meta-analyses, separated into: Anorexia Nervosa; Anorexia Nervosa, Restricting subtype; Anorexia Nervosa, Binge-Purge subtype, Bulimia Nervosa and Binge Eating Disorder. For all groups, there were significant differences with medium or large effect sizes between the clinical group and HCs, with the clinical group scoring significantly higher on the TAS, indicating greater difficulty with identifying and labelling emotions.
Across the spectrum of eating disorders, individuals report having difficulties recognising or describing their emotions. Given the self-report design of the TAS, research to develop and evaluate treatments and clinician-administered assessments of alexithymia is warranted.
本综述的目的是综合有关多伦多述情障碍量表（TAS）在饮食失调人群和健康对照者（HCs）中使用情况的文献，并比较这些组的TAS得分。
系统检索电子数据库以查找使用TAS的研究，并进行荟萃分析以统计比较饮食失调个体与HCs之间的TAS得分。
共识别出48项同时使用TAS研究临床饮食失调组和HCs的研究。其中，44项纳入荟萃分析，分为：神经性厌食症；神经性厌食症，限制型亚型；神经性厌食症，暴食-清除型亚型，神经性贪食症和暴饮暴食症。对于所有组，临床组与HCs之间存在显著差异，效应大小为中等或较大，临床组在TAS上得分显著更高，表明在识别和标记情绪方面存在更大困难。
在整个饮食失调范围内，个体报告在识别或描述自己的情绪方面存在困难。鉴于TAS的自我报告设计，有必要开展研究以开发和评估治疗方法以及临床医生对述情障碍的评估。
