Chronic pain's influence on emotional well-being can be significant. It may evoke feelings of despair, frustration, nervousness, and melancholy in individuals, which often manifest as reactions to enduring pain and disruptions in their daily lives. In this study, we seek to perform Bootstrap Exploratory Graph Analysis (EGA) on the Persian Version of the Perth Alexithymia Questionnaire (PAQ) in a cohort of people with chronic pain.
The research concentrated on the population of individuals encountering chronic pain within Tehran province from 2022 to 2023. Ultimately, the analysis comprised information from 234 male participants (with a mean age of 30.59, SD = 6.84) and 307 female participants (with a mean age of 30.16, SD = 6.65). After data collection, statistical analysis was conducted using the EGAnet2.0.4 package in R.4.3.2 software.
The outcome of bootstrapped EGA unveiled a two-dimensional configuration of the PAQ comprising Factor 1 denoted as negative difficulty in describing and identifying feelings (N-DDIF) and Factor 2 characterized as general-externally orientated thinking (GEOT), representing robust structural integrity and item consistency (all items have stabilities > 0.70).
These findings endorse the validity of the PAQ, as evidenced by its confirmation in a broader sample using a novel methodology consistent with existing literature on two-factor decentering models.
慢性疼痛对情绪健康的影响可能很大。它可能会在个体中引发绝望、沮丧、紧张和忧郁等情绪，这些情绪通常表现为对持续疼痛和日常生活中断的反应。在本研究中，我们试图对一组慢性疼痛患者的波斯语版珀斯述情障碍问卷（PAQ）进行Bootstrap探索性图形分析（EGA）。
该研究集中于2022年至2023年德黑兰省患有慢性疼痛的人群。最终，分析纳入了234名男性参与者（平均年龄30.59岁，标准差=6.84）和307名女性参与者（平均年龄30.16岁，标准差=6.65）的信息。数据收集后，使用R.4.3.2软件中的EGAnet2.0.4包进行统计分析。
Bootstrap EGA的结果揭示了PAQ的二维结构，包括表示描述和识别情感方面的消极困难的因子1（N-DDIF）和表示一般外部导向思维的因子2（GEOT），显示出强大的结构完整性和项目一致性（所有项目的稳定性>0.70）。
这些发现支持了PAQ的有效性，这在更广泛的样本中得到了证实，采用了与现有关于双因素去中心化模型的文献一致的新方法。
