ABSTRACT

Background

The most extensively used instrument to measure dissociation is the Dissociative Experiences Scale (DES). Recently, an extended version of this instrument was provided, which also measures somatoform symptoms of dissociation. The aim of this study was to examine the component structure and internal consistency of the extended version of the Dissociative Experiences Scale (FDS) in patients diagnosed with substance use disorders (SUD).

Methods

Principal component analyses (PCAs) were conducted in a large clinical sample of patients diagnosed with SUD (n = 459) for the 44 FDS items, the 28 original DES items, the 23 items of the original DES subscales that compose FDS subscales of amnesia, absorption, and depersonalization/derealization, and the 9 conversion subscale items.

Results

PCA of all 44 FDS items yielded a 9-factor solution where the first factor explained 32% variance. A 6-, 4-, and 2-factor solution, respectively, was found for 28 DES original items, 23 items of original DES subscales that compose FDS subscales of amnesia, absorption, and depersonalization/derealization, and 9 items of the conversion subscale of the FDS.

Conclusion

FDS proves to be a reliable tool that can be used to screen patients with SUD for dissociative psychopathology within the ICD and DSM-5 framework.

在被诊断患有物质使用障碍的患者中验证分离体验量表 (DES) 的扩展版本

摘要

背景

测量分离最广泛使用的工具是分离体验量表(DES)。最近,提供了该仪器的扩展版本,它还可以测量分离的躯体形式症状。本研究的目的是检查被诊断患有物质使用障碍 (SUD) 的患者的分离体验量表 (FDS) 扩展版的组成结构和内部一致性。

方法

对 44 个 FDS 项目、28 个原始 DES 项目、构成健忘症 FDS 子量表的原始 DES 子量表的 23 个项目、诊断为 SUD(n = 459)的大量临床样本进行主成分分析(PCA),吸收、人格解体/现实解体,以及 9 个转换分量表项目。

结果

所有 44 个 FDS 项目的 PCA 产生了一个 9 因素解决方案,其中第一个因素解释了 32% 的方差。分别为 28 个 DES 原始项目、23 个原始 DES 子量表(构成健忘症、吸收和人格解体/去现实化的 FDS 子量表)和 9 个转换子量表找到了 6 因子、4 因子和 2 因子解的 FDS。

结论

FDS 被证明是一种可靠的工具,可用于在 ICD 和 DSM-5 框架内筛查 SUD 患者的分离性精神病理学。
