Alexithymia is defined as the lack of words to describe emotions and is associated with different psychopathologies. Various tools have been developed for measuring alexithymia; each has its limitations. A new questionnaire, Perth Alexithymia Questionnaire (PAQ), was developed to simultaneously assess positive and negative dimensions. Validation of such a tool in different cultures allows cross-cultural health psychology studies and facilitates knowledge transfer in the field. We aimed to examine the psychometric features of the PAQ in the Farsi-speaking population in Iran. Four-hundred-twenty-nine university students were asked to complete the PAQ, the Toronto Alexithymia Scale (TAS-20), Beck Depression Inventory (BDI-II), Beck Anxiety Inventory (BAI), and emotion regulation questionnaire (ERQ). Concurrent validity, discriminant validity, internal consistency, and test-retest reliability and factor structure were investigated. Confirmatory factor analysis showed a five-factor model identical to the original questionnaire. The questionnaire indicated good internal consistency (0.82 < α < 0.94). Test-retest reliability was acceptable for all subscales. The correlations between PAQ and its subscales with BDI-II, BAI, and TAS, and expression suppression subscale of ERQ were strong for concurrent validity. Concerning the discriminant validity, PAQ and its subscales were not correlated with reappraisal subscales of ERQ. The present findings suggest that the Farsi version of PAQ has strong psychometric properties and is appropriate for use in the Farsi-speaking population.
述情障碍被定义为缺乏描述情感的词汇，并且与不同的精神病理学相关。已经开发了各种工具来测量述情障碍；每种工具都有其局限性。一种新的问卷，即珀斯述情障碍问卷（PAQ），被开发出来以同时评估积极和消极维度。在不同文化中对这样一种工具进行验证有助于跨文化健康心理学研究，并促进该领域的知识转移。我们旨在研究PAQ在伊朗说波斯语人群中的心理测量特征。429名大学生被要求完成PAQ、多伦多述情障碍量表（TAS - 20）、贝克抑郁量表（BDI - II）、贝克焦虑量表（BAI）和情绪调节问卷（ERQ）。研究了同时效度、区分效度、内部一致性、重测信度和因子结构。验证性因子分析显示了一个与原始问卷相同的五因子模型。该问卷显示出良好的内部一致性（0.82 < α < 0.94）。所有子量表的重测信度均可接受。PAQ及其子量表与BDI - II、BAI和TAS以及ERQ的表达抑制子量表之间的相关性很强，具有同时效度。关于区分效度，PAQ及其子量表与ERQ的重新评价子量表不相关。目前的研究结果表明，波斯语版的PAQ具有很强的心理测量特性，适用于说波斯语的人群。
