The present study aimed to evaluate the psychometric properties of a Persian version of the Psychological Flexibility Epilepsy Questionnaire (P-PFEQ). Transcultural adaptation and validation of the Persian version of the PFEQ were performed using translation and back-translation with pilot testing (on 17 patients) and expert evaluation. Participants in the current study involved 100 patients with an EEG-verified epilepsy diagnosis and an average age of 30.96 years (SD ± 6.46) (63% were female). Data collection included a sociodemographic questionnaire, epilepsy-specific questionnaire, the Depression-Anxiety-stress scale (DASS-21), the Insomnia Severity Index (ISI), the 31-item Quality-of-Life questionnaire in Epilepsy (QOLIE-31), the Acceptance and Action Questionnaire (AAQ), the Committed Action Questionnaire (CAQ), and the short form of the Freiburg Mindfulness Inventory (FMI). Descriptive and inferential analyses were conducted by SPSS software V.26. The P-PFEQ demonstrated semantic, conceptual, and content validity in equivalence with the Swedish version. Based on Exploratory Factor Analysis (EFA), five items were eliminated and unidimensional scale of PFEQ with 12 items, explaining 50.38% of the total variance, was accepted. The scale showed good reliability through internal consistency (Cronbach's α of 0.9) and temporal stability on retest (n = 85, Intraclass correlation = 0.92). Convergent and divergent validity findings were acceptable for the P-PFEQ. The findings show that the P-PFEQ is a reliable and valid scale for assessing psychological flexibility in the Iranian patients with epilepsy. Also, it can be confidently recommended as a useful instrument in clinical practice.
本研究旨在评估波斯语版心理灵活性癫痫问卷（P-PFEQ）的心理测量特性。采用翻译、回译、预测试（对17名患者）和专家评估的方法对波斯语版PFEQ进行跨文化调适和验证。本研究的参与者包括100名经脑电图证实患有癫痫的患者，平均年龄为30.96岁（标准差±6.46）（63%为女性）。数据收集包括社会人口学问卷、癫痫特异性问卷、抑郁-焦虑-压力量表（DASS-21）、失眠严重程度指数（ISI）、癫痫生活质量问卷31项版（QOLIE-31）、接受与行动问卷（AAQ）、承诺行动问卷（CAQ）以及弗莱堡正念量表简版（FMI）。使用SPSS软件V.26进行描述性和推断性分析。P-PFEQ在语义、概念和内容效度方面与瑞典语版相当。基于探索性因子分析（EFA），剔除了5个项目，接受了由12个项目组成的PFEQ单维度量表，该量表解释了总方差的50.38%。该量表通过内部一致性（Cronbach's α为0.9）和重测时的时间稳定性（n = 85，组内相关系数 = 0.92）显示出良好的信度。P-PFEQ的收敛效度和区分效度结果均可接受。研究结果表明，P-PFEQ是评估伊朗癫痫患者心理灵活性的可靠且有效的量表。此外，它可以被放心地推荐为临床实践中的有用工具。
