The ICD-11 includes posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) as two distinct disorders. Several empirical studies have supported the distinction between PTSD and CPTSD in various trauma population and different culture backgrounds. However, research documenting qualitatively distinction between PTSD and CPTSD using the International Trauma Questionnaire (ITQ) in a large general population from non-English-speaking countries is limited.
Self-report measures were used to assess CPTSD, dissociation, depression, and posttraumatic growth in a sample of 1,760 Chinese college students who had experienced at least one traumatic event. Latent profile analysis was utilized to identify the number of classes based on the 18-item version of ITQ.
A four-class solution (low symptoms, disturbance of self-organization, PTSD, CPTSD) was the most appropriate one in our study. Compared to the PTSD class, the CPTSD class was associated with more serious psychopathology symptoms.
Sample characteristics in this study limit its generalizability to other population (e.g., low educational level, clinical sample). The type of traumatic event in predicting distinct classes should also be investigated in future studies.
Distinction between PTSD and CPTSD as ICD-11 proposed was supported in a Chinese young adult sample. DSO symptoms might inhibit healing and recovery process, and subsequent intervention could consider treat CPTSD based on addressing DSO symptoms.
ICD-11 将创伤后应激障碍（PTSD）和复杂创伤后应激障碍（CPTSD）列为两种不同的疾病。多项实证研究支持 PTSD 和 CPTSD 在不同的创伤人群和不同文化背景中的区分。然而，使用国际创伤问卷（ITQ）在非英语国家的大型普通人群中记录 PTSD 和 CPTSD 之间定性区别的研究有限。
使用自我报告的测量方法评估了经历至少一次创伤事件的 1760 名中国大学生的 CPTSD、解离、抑郁和创伤后成长。基于 ITQ 的 18 项版本，利用潜在剖面分析确定了类别的数量。
在我们的研究中，四分类解决方案（低症状、自我组织障碍、PTSD、CPTSD）是最合适的。与 PTSD 组相比，CPTSD 组的精神病理学症状更为严重。
本研究中的样本特征限制了其在其他人群（例如，低教育水平、临床样本）中的普遍性。在预测不同类别时，创伤事件的类型也应在未来的研究中进行调查。
在一个中国年轻成年人样本中支持了 ICD-11 提出的 PTSD 和 CPTSD 的区分。DSO 症状可能会抑制愈合和恢复过程，随后的干预措施可以考虑基于解决 DSO 症状来治疗 CPTSD。
