ABSTRACT

Background: The formulations of post-traumatic stress disorder (PTSD) and the newly included disorder complex PTSD (CPTSD) in the 11th edition of the International Classification of Diseases (ICD-11) have not been evaluated on a broad range of maladaptive personality traits.

Objective: The aim of this study was to evaluate ICD-11 PTSD and CPTSD on maladaptive personality traits.

Method: In a cross-sectional study of 106 Danish outpatients with ICD-10 PTSD, we used the International Trauma Questionnaire (ITQ) to identify patients with either ICD-11 PTSD or CPTSD (N = 84). We utilized the Personality Inventory for DSM-5 (PID-5) from the alternative model of personality disorders in DSM-5, section III, to evaluate personality trait differences between ICD-11 PTSD and CPTSD. Furthermore, PID-5 was also used to investigate relationships between personality traits and ICD-11 PTSD/CPTSD symptom clusters. The Life Event Checklist was used to assess traumatic experiences, and the MINI International Neuropsychiatric Interview was applied to assess comorbidity.

Results: Patients with ICD-11 PTSD or CPTSD had elevated scores on personality traits indicative of internalizing psychopathology. However, higher impairment levels of the trait domains Negative Affectivity (d= 0.75) and Psychoticism (d = 0.80) discriminated patients with ICD-11 CPTSD from patients with PTSD. The PID-5 trait domain Detachment was moderately positively correlated to most of the ITQ symptom clusters and, the ITQ Negative Self-concept symptom cluster showed a relatively high number of significant correlations across all the PID-5 trait domains and facets. The PID-5 domain Negative Affectivity and almost all the encompassing facets were significantly correlated with DSO symptom clusters.

Conclusions: The findings demonstrate the relevance of applying dimensional assessment of personality features to study the psychopathology of ICD-11 PTSD and CPTSD and potential differences. The results suggest that CPTSD is a more debilitating disorder than PTSD considering the severity of the personality features.

ICD-11 PTSD 和复杂 PTSD 在 DSM-5 第 III 节人格特质上的差异

摘要

背景:第 11 版国际疾病分类(ICD-11 ) 中创伤后应激障碍 (PTSD) 和新纳入的复杂性障碍 PTSD (CPTSD) 的表述尚未针对广泛的适应不良人格特征进行评估.

目的:本研究的目的是评估 ICD-11 PTSD 和 CPTSD 对适应不良人格特质的影响。

方法:在一项针对 106 名患有 ICD-10 PTSD 的丹麦门诊患者的横断面研究中,我们使用国际创伤问卷 (ITQ) 来识别患有 ICD-11 PTSD 或 CPTSD 的患者(N = 84 。我们利用 DSM-5 第三部分人格障碍替代模型中的 DSM-5 人格量表 (PID-5) 来评估 ICD-11 PTSD 和 CPTSD 之间的人格特质差异。此外,PID-5 还用于调查人格特质与 ICD-11 PTSD/CPTSD 症状群之间的关系。生活事件清单用于评估创伤经历,MINI 国际神经精神病学访谈用于评估合并症。

结果:患有 ICD-11 PTSD 或 CPTSD 的患者在人格特质上得分较高,表明内化精神病理学。然而,负面情感 ( d = 0.75) 和精神病 ( d = 0.80)特征域的较高损伤水平将 ICD-11 CPTSD 患者与 PTSD 患者区分开来。PID-5 特征域分离与大多数 ITQ 症状群呈适度正相关,而 ITQ 消极自我概念症状群在所有 PID-5 特征域和方面显示出相对较多的显着相关性。PID-5 域的负面情感和几乎所有包含的方面都与 DSO 症状群显着相关。

结论:研究结果证明了应用人格特征维度评估研究 ICD-11 PTSD 和 CPTSD 的精神病理学和潜在差异的相关性。结果表明,考虑到人格特征的严重性,CPTSD 是一种比 PTSD 更令人虚弱的疾病。
