Dissociative experiences commonly occur in schizophrenia spectrum disorders (SSD). Yet little is known about how dissociative experiences in SSD are related to SSD symptoms. Accordingly, we investigated the relations between dissociative experiences and SSD symptoms, focusing on symptoms bridging these 2 symptom clusters as well as their relation to reported trauma history.
Network analyses were conducted on the responses of 248 individuals with an SSD who enrolled from multiple mental health centers in The Netherlands. Dissociative experiences were assessed via the Dissociative Experience Scale, SSD symptoms using the Positive and Negative Syndrome Scale, and trauma history through the Trauma History Questionnaire.
The results indicated that dissociative symptoms in SSD are mostly independent of other symptoms, but that emotional distress bridges between the dissociative and SSD symptom clusters. Furthermore, results revealed associations between positive and negative SSD symptoms and trauma through emotional distress, whereas dissociative symptoms remained relatively isolated.
Because SSD symptoms and dissociative experiences clustered relatively independent from each other, our findings promote the idea of tailored treatment approaches for individuals with an SSD with frequent dissociative experiences, specifically targeting these symptoms.
分离体验在精神分裂症谱系障碍（SSD）中较为常见。然而，对于 SSD 中的分离体验与 SSD 症状之间的关系，我们知之甚少。因此，我们研究了分离体验与 SSD 症状之间的关系，重点关注连接这两个症状群的症状，以及它们与报告的创伤史之间的关系。
我们对来自荷兰多个心理健康中心的 248 名 SSD 患者的反应进行了网络分析。使用分离体验量表评估分离体验，使用阳性和阴性综合征量表评估 SSD 症状，使用创伤史问卷评估创伤史。
结果表明，SSD 中的分离症状在很大程度上独立于其他症状，但情绪困扰将分离和 SSD 症状群联系在一起。此外，结果显示，通过情绪困扰，阳性和阴性 SSD 症状与创伤之间存在关联，而分离症状则相对孤立。
由于 SSD 症状和分离体验相对独立，我们的发现支持为经常出现分离体验的 SSD 患者制定个性化治疗方法的想法，特别是针对这些症状。
