Abstract

Previous research has suggested the presence of various subtypes in posttraumatic stress disorder (PTSD) in patient populations. The purpose of this study was to explore the presence of various subtypes in PTSD in veterans referred for traumatic brain injury evaluation. As a focus of this analysis, comorbid symptoms (i.e., anxiety, depression, and neurobehavioral) were used to divide a polytrauma sample of veterans with diagnosed PTSD into clusters. The presence of a three-cluster solution was identified and validated with two types of cluster analysis. Discussion of the nature of the three subtypes of PTSD and implications for treatment are presented.

摘要

先前的研究表明，患者群体中存在创伤后应激障碍 (PTSD) 的各种亚型。本研究的目的是探讨在接受创伤性脑损伤评估的退伍军人中存在 PTSD 的各种亚型。作为本次分析的重点，共病症状（即焦虑、抑郁和神经行为）被用于将诊断为 PTSD 的退伍军人的多发性创伤样本分成几组。使用两种类型的聚类分析来识别和验证三聚类解决方案的存在。讨论了三种 PTSD 亚型的性质以及对治疗的影响。
