ABSTRACT

A total of 491 participants from four previous studies, 443 of whom were diagnosed with dissociative identity disorder (DID) on the Dissociative Disorders Interview Schedule, completed the Dissociative Experiences Scale (DES). Their results were analyzed to determine how many were in the dissociative taxon (DES-T) on the DES. Of the 443 individuals with DID, 419 (94.6%) were in the taxon, 13 (2.9%) were out of the taxon and 11 (2.5%) were indeterminate. The DES-T is therefore very effective at identifying people with DID as being in the dissociative taxon, although it does have a false negative rate of 5.4%. Out of 48 people with no dissociative disorder on the Dissociative Disorders Interview Schedule, the DES-T identified 26 (54.2%) as being in the taxon and 22 (45.8%) as being out of the taxon with no indeterminate cases. The clinical diagnoses of these 48 individuals are unknown: all were inpatients in the same Trauma Program. Thus, the sensitivity of the DES-T for confirming that individuals with DID are in the dissociative taxon was 94.6% and the specificity of the DES-T for confirming that individuals with no dissociative disorder are not in the dissociative taxon was 45.8%. It is possible that the DES-T yields false positives for taxon membership; this possibility should be investigated in future research.

摘要

来自四项先前研究的总共 491 名参与者完成了分离体验量表 (DES)，其中 443 人在分离障碍访谈时间表中被诊断出患有分离性身份障碍 (DID)。对他们的结果进行了分析，以确定 DES 上的分离分类群 (DES-T) 中有多少。在 443 名患有 DID 的个体中，419 人 (94.6%) 在分类群中，13 (2.9%) 在分类群外，11 (2.5%) 是不确定的。因此，DES-T 在将 DID 患者识别为游离分类群方面非常有效，尽管它的假阴性率为 5.4%。在分离性障碍访谈时间表中没有分离性障碍的 48 人中，DES-T 确定 26 (54.2%) 人在分类群中，22 (45.8%) 人在没有不确定病例的分类群之外。这 48 人的临床诊断未知：他们都是同一创伤计划的住院患者。因此，DES-T 用于确认患有 DID 的个体在分离分类群中的敏感性为 94.6%，而用于确认没有分离障碍的个体不在分离分类群中的 DES-T 的特异性为 45.8%。DES-T 可能会对分类单元成员产生误报；在未来的研究中应该调查这种可能性。DES-T 可能会对分类单元成员产生误报；在未来的研究中应该调查这种可能性。DES-T 可能会对分类单元成员产生误报；在未来的研究中应该调查这种可能性。
