ABSTRACT

Background and Objectives

Construct and discriminant validity of the ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) has been examined worldwide. However, little is known about CPTSD in Korean population who are suffering with long-term responses of organized violence in their context.

Design

This study conducted a cross-sectional survey to assess the construct and discriminant validity of the ICD-11 PTSD and CPTSD using the Korean International Trauma Questionnaire (ITQ) among organized violence survivors of past political oppression (from 1940s to 2010s) in South Korea.

Method

A total of 236 survivors and families completed the survey including the ITQ. A confirmatory factor analysis and a multinomial logistic regression were conducted.

Results

A second-order eight-factor, the ICD-11 CPTSD model, best described the structure of CPTSD. Compared to the non-diagnosed group, having above median score of cumulative trauma was a risk factor for PTSD [Odds ratio (OR) = 3.18] and CPTSD (OR = 3.27). Having above median score of cumulative social stressors increased the risk of CPTSD, relative to PTSD (OR = 4.84), and to the non-diagnosed group (OR = 7.79).

Conclusions

The ITQ seemed applicable to the Korean culture, showing a valid construct and meaningfully distinguishing ICD-11 PTSD and CPTSD.

ICD-11 创伤后应激障碍 (PTSD) 和韩国现代政治压迫历史中有组织的暴力幸存者的复杂 PTSD

摘要

背景和目标

ICD-11 创伤后应激障碍 (PTSD) 和复杂 PTSD (CPTSD) 的构造效度和判别效度已在世界范围内得到检验。然而，韩国人对 CPTSD 知之甚少，这些人在他们的背景下长期遭受有组织的暴力反应。

设计

本研究进行了一项横断面调查，使用韩国国际创伤问卷 (ITQ) 在韩国过去政治压迫（从 1940 年代至 2010 年代）的有组织暴力幸存者中评估 ICD-11 PTSD 和 CPTSD 的结构和区分效度。

方法

共有 236 名幸存者和家庭完成了包括 ITQ 在内的调查。进行了验证性因素分析和多项逻辑回归。

结果

二阶八因子 ICD-11 CPTSD 模型最能描述 CPTSD 的结构。与未确诊组相比，累积创伤得分高于中位数是 PTSD [优势比 (OR) = 3.18] 和 CPTSD (OR = 3.27) 的危险因素。相对于 PTSD (OR = 4.84) 和未诊断组 (OR = 7.79)，累积社交压力的中位数高于中位数会增加 CPTSD 的风险。

结论

ITQ 似乎适用于韩国文化，显示出有效的结构并有意义地区分 ICD-11 PTSD 和 CPTSD。
