Background:

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).

Methods:

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).

Results:

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.

Conclusion:

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.

解离性障碍的唤醒能力、人格和决策能力

背景：

尽管该障碍具有很强的历史根源，但在理解解离性转换障碍 (DCD) 的发病机制方面仍存在差距。现在强调人格和神经认知因素的作用；然而，有不一致的报道。本研究以健康对照组 (HCG) 为参考，探讨 DCD 患者的性格倾向、唤醒能力和决策能力。

方法：

在这项横断面研究中，样本包括 10 名患有 DCD 的成年精神病患者。HCG 的 10 名参与者根据年龄、性别、教育、经济状况、住所、宗教背景和惯用手进行匹配。该研究通过气质和性格量表评估人格倾向，通过反应时间任务评估兴奋性，通过爱荷华赌博任务（IGT PEBL 版本）评估决策能力。

结果：

DCD 组在与气质和性格相关的性格倾向上存在显着差异。也有证据表明容易被唤醒和沮丧，以及与决策能力相关的执行功能缺陷。

结论：

这项研究强调了与 DCD 相关的气质和性格因素的存在。此外，本研究确定了认知唤醒和决策或反馈利用能力在 DCD 精神病理学中的作用。
