Dissociation was one of the roots of the nosopoetic construct "schizophrenia", and a link seems to exist between psychotic and dissociative phenomena. We explored the relationship between dissociation and schizoidia as defined by the Dissociative Experiences Scale (DES) total score and the schizoidia subscale of the Munich Personality Test (MPT), respectively. The study comprised 43 outpatients diagnosed with schizophrenia spectrum disorders in remission, 47 outpatients with personality disorders and 42 non-patients. Besides the DES and the MPT, all participants also completed parts of the Symptom Checklist (SCL-90-R) and theTrauma Questionnaire (TQ). In the final multivariable logistic model, a set of five variables was identified as the strongest contributors to the occurrence of schizoida. The model included TQ broken home, MPT neuroticism, schizophrenia spectrum and personality disorder diagnoses, and SCL aggressivity; it did not include any dissociation variable. The purported relationship between dissociation and schizoidia could not be confirmed; the existence of schizophrenia-inherent dissociation appears questionable.
分离是疾病构成“精神分裂症”的根源之一，并且精神病性现象和解离现象之间似乎存在联系。我们分别通过解离体验量表（DES）总分和慕尼黑人格测试（MPT）的分裂样特质分量表来探究解离与分裂样特质之间的关系。该研究纳入了43名处于缓解期的精神分裂症谱系障碍门诊患者、47名人格障碍门诊患者和42名非患者。除了DES和MPT外，所有参与者还完成了症状自评量表（SCL - 90 - R）和创伤问卷（TQ）的部分内容。在最终的多变量逻辑模型中，一组五个变量被确定为对分裂样特质发生的最强影响因素。该模型包括TQ中的家庭破裂、MPT中的神经质、精神分裂症谱系和人格障碍诊断以及SCL中的攻击性；它不包括任何解离变量。解离与分裂样特质之间所谓的关系无法得到证实；精神分裂症固有的解离现象的存在似乎存在疑问。
