Abstract

Objective: This study sought to determine the utility of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) in accurately distinguishing genuine dissociative identity disorder (DID) patients from coached and uncoached DID simulators.

Method: DID patients (n = 34) who were diagnosed using the Structured Clinical Interview for DSM-IV-Dissociative Disorders were recruited from inpatient and outpatient settings. Coached (n = 25) and uncoached (n = 64) simulator groups were recruited from a Mid-Atlantic university. All participants completed the MMPI-2.

Results: MMPI-2 validity scales reliably distinguished simulators from DID patients with high sensitivity (0.95) and specificity (0.97). The scales showing greatest promise making the distinction were F minus K index, back infrequency scale, and superlative self-presentation. Simulators and genuine DID patients also differed in their pattern of symptoms. All results were calculated with White female DID patients and simulators only.

Conclusions: Genuine DID patients can be differentiated from simulators. Simulators appear to overweight symptoms of paranoia and alienation relative to mood and somatic symptoms. Further research is needed to generalize these findings to male and non-White populations. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

明尼苏达多相人格量表-2在区分真性与假性分离性身份障碍中的应用。

目的:本研究旨在确定明尼苏达多相人格量表-2 (MMPI-2)在准确区分真正的分离性身份障碍(DID)患者与训练过的和未训练过的DID模拟者中的效用。方法:从住院和门诊招募使用dsm - iv -分离性障碍结构化临床访谈诊断的DID患者(n = 34)。经过训练(n = 25)和未经训练(n = 64)的模拟器组从中大西洋大学招募。所有参与者都完成了MMPI-2。结果:MMPI-2效度量表以高灵敏度(0.95)和特异性(0.97)可靠地区分模拟者和DID患者。最有希望做出区分的量表是F - K指数、回频率量表和最高自我表现量表。模拟患者和真正的DID患者在症状模式上也存在差异。所有结果仅以白人女性DID患者和模拟器计算。结论:真实DID患者可以与模拟DID患者区分开来。模拟者表现出超重症状偏执和疏离相对于情绪和躯体症状。需要进一步的研究将这些发现推广到男性和非白人人群。(PsycInfo数据库记录(c) 2023 APA，版权所有)。
