This study examined evidence for a dissociative subtype of post-traumatic stress disorder (PTSD) among women seeking psychotherapy for childhood sexual abuse (CSA). One hundred and twenty-two women seeking treatment for CSA completed a battery of questionnaires assessing PTSD, dissociative symptoms, and child maltreatment. Using signal detection analysis, we identified high and low dissociation PTSD subgroups. A constellation of three PTSD symptoms-hypervigilance, sense of foreshortened future, and sleep difficulties-discriminated between these two subgroups (OR = 8.15). Further evidence was provided by the finding of a nonlinear relationship between severity of childhood maltreatment and dissociation in the women with PTSD. These results provide support for a dissociative subtype of PTSD that may stem from more severe childhood experiences of neglect and abuse.
本研究调查了在因童年期性虐待（CSA）而寻求心理治疗的女性中，创伤后应激障碍（PTSD）的分离亚型的证据。122名因CSA寻求治疗的女性完成了一系列评估PTSD、分离症状和儿童期虐待情况的问卷。通过信号检测分析，我们确定了高分离PTSD亚组和低分离PTSD亚组。一组三种PTSD症状——过度警觉、对未来的缩短感和睡眠困难——区分了这两个亚组（OR = 8.15）。PTSD女性中童年期虐待的严重程度与分离之间存在非线性关系这一发现提供了进一步的证据。这些结果为PTSD的分离亚型提供了支持，该亚型可能源于更严重的童年期忽视和虐待经历。
