This study compared dissociative symptom areas in Vietnam combat veterans with posttraumatic stress disorder (PTSD) and in Vietnam combat veterans without PTSD.
The Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D) was used to compare dissociative symptoms in 40 Vietnam combat veterans with PTSD and 15 Vietnam combat veterans without PTSD. The SCID-D yields a total score and scores in five symptom areas: amnesia, depersonalization, derealization, identity confusion, and identity alteration.
The PTSD patients had more severe dissociative symptoms in each of the five symptom areas of the SCID-D and higher total symptom scores. Amnesia was the symptom area with the greatest difference in scores between the PTSD patients (mean = 3.68, SD = 0.73) and the non-PTSD veterans (mean = 1.06, SD = 0.26).
The finding of higher levels of dissociative symptoms in Vietnam combat veterans with PTSD than in Vietnam veterans without PTSD is consistent with a level of dissociative symptoms in PTSD similar to that in dissociative disorders.
本研究比较了患有创伤后应激障碍（PTSD）的越南退伍军人与未患PTSD的越南退伍军人的分离症状领域。
采用《精神疾病诊断与统计手册》第四版分离障碍结构化临床访谈（SCID-D），比较40名患有PTSD的越南退伍军人和15名未患PTSD的越南退伍军人的分离症状。SCID-D得出总分以及五个症状领域的得分：失忆、人格解体、现实解体、身份混淆和身份改变。
PTSD患者在SCID-D的五个症状领域中的每一个都有更严重的分离症状，且总症状得分更高。失忆是PTSD患者（均值=3.68，标准差=0.73）和未患PTSD的退伍军人（均值=1.06，标准差=0.26）得分差异最大的症状领域。
患有PTSD的越南退伍军人比未患PTSD的越南退伍军人有更高水平的分离症状这一发现，与PTSD中分离症状的水平与分离障碍中的水平相似是一致的。
