第五版精神障碍诊断和统计手册（DSM-5;美国精神病学协会，2013）包含创伤后应激障碍（PTSD）的分离亚型，其特征是显著的人格解体和现实解体。在这项研究中，使用潜在特征分析对541名遭受创伤的大学生样本进行了创伤后应激障碍分离亚型检查。PTSD检查表和多尺度分离量表中的项目被用作潜在类别指标。结果支持3类解决方案，包括一个良好的调整类，创伤后应激障碍类，和创伤后应激障碍/解离类，其特征是创伤后应激障碍，人格解体和现实解体的症状升高。显着的类差异被发现在一些措施相关的精神病理学与科恩的d效应大小估计范围从0.04到1.86。关于解离亚型的诊断和治疗的影响进行了讨论。
The fifth edition of Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013) contains a dissociative subtype for posttraumatic stress disorder (PTSD) characterized by significant depersonalization and derealization. In this study the PTSD dissociative subtype was examined using latent profile analysis in a sample of 541 trauma-exposed college students. Items from the PTSD Checklist and Multiscale Dissociation Inventory were used as latent class indicators. Results supported a 3-class solution including a well-adjusted class, a PTSD class, and a PTSD/dissociative class characterized by elevated symptoms of PTSD, depersonalization, and derealization. Significant class differences were found on a number of measures of related psychopathology with Cohen's d effect size estimates ranging from 0.04 to 1.86. Diagnostic and treatment implications regarding the dissociative subtype are discussed.
