There is a gap in understanding the pathogenesis of dissociative conversion disorder (DCD), despite the disorder having a strong historical root. The role of personality and neurocognitive factors are now highlighted; however, inconsistencies are reported. This study explores the personality disposition, arousability, and decision-making ability of patients with DCD, in reference to a healthy control group (HCG).
In this cross-sectional study, the sample comprised ten adult psychiatric patients with DCD. Ten participants of the HCG were matched according to age, gender, education, economic status, domicile, religious background, and handedness. The study assessed personality disposition with Temperament and Character Inventory, arousability with reaction time task, and decision-making ability with the Iowa Gambling Task (IGT PEBL version).
The DCD group differed significantly on personality disposition related to both temperament and character. There was also evidence of easy arousability and frustration along with deficit in executive function related to decision-making ability.
This study highlights the presence of both temperamental and characterological factors associated with DCD. Moreover, this study identifies the role of cognitive arousability and decision-making or feedback utilization ability in the psychopathology of DCD.
尽管分离性转换障碍（DCD）有着深厚的历史根源，但在理解其发病机制方面仍存在差距。目前，人格和神经认知因素的作用受到了关注；然而，研究结果并不一致。本研究以健康对照组（HCG）为参照，探讨了DCD患者的人格特质、易唤醒性和决策能力。
在这项横断面研究中，样本包括10名成年精神科DCD患者。根据年龄、性别、教育程度、经济状况、居住地、宗教背景和利手，选取了10名HCG参与者作为匹配对象。本研究使用气质和性格量表评估人格特质，通过反应时间任务评估易唤醒性，并使用爱荷华赌博任务（IGT PEBL版本）评估决策能力。
DCD组在与气质和性格相关的人格特质方面存在显著差异。此外，有证据表明DCD组存在易唤醒性和挫折感，且在与决策能力相关的执行功能方面存在缺陷。
本研究强调了与DCD相关的气质和性格因素的存在。此外，本研究确定了认知易唤醒性以及决策或反馈利用能力在DCD精神病理学中的作用。
