Elevated scores on some MMPI-2 (Minnesota Multiphasic Inventory-2) validity scales are common among patients with dissociative identity disorder (DID), which raises questions about the validity of their responses. Such patients show elevated scores on atypical answers (F), F-psychopathology (Fp), atypical answers in the second half of the test (FB), schizophrenia (Sc), and depression (D) scales, with Fp showing the greatest utility in distinguishing them from coached and uncoached DID simulators. In the current study, we investigated the items on the MMPI-2 F, Fp, FB, Sc, and D scales that were most and least commonly endorsed by participants with DID in our 2014 study and compared these responses with those of coached and uncoached DID simulators. The comparisons revealed that patients with DID most frequently endorsed items related to dissociation, trauma, depression, fearfulness, conflict within family, and self-destructiveness. The coached group more successfully imitated item endorsements of the DID group than did the uncoached group. However, both simulating groups, especially the uncoached group, frequently endorsed items that were uncommonly endorsed by the DID group. The uncoached group endorsed items consistent with popular media portrayals of people with DID being violent, delusional, and unlawful. These results suggest that item endorsement patterns can provide useful information to clinicians making determinations about whether an individual is presenting with DID or feigning.
在分离性身份障碍（DID）患者中，明尼苏达多相人格测验第二版（MMPI - 2）某些效度量表得分升高很常见，这引发了对其回答效度的质疑。这类患者在异常回答（F）、F - 精神病理学（Fp）、测验后半部分的异常回答（FB）、精神分裂症（Sc）和抑郁（D）量表上得分升高，其中Fp量表在区分他们与有指导和无指导的DID模拟者方面最有用。在当前研究中，我们调查了2014年研究中DID参与者在MMPI - 2的F、Fp、FB、Sc和D量表上最常和最不常认可的项目，并将这些回答与有指导和无指导的DID模拟者的回答进行比较。比较结果显示，DID患者最常认可与解离、创伤、抑郁、恐惧、家庭冲突和自我毁灭相关的项目。有指导的模拟组比无指导的模拟组更成功地模仿了DID组的项目认可情况。然而，两个模拟组，尤其是无指导的模拟组，经常认可DID组不常认可的项目。无指导的模拟组认可的项目与大众媒体对患有DID的人暴力、妄想和违法的描绘一致。这些结果表明，项目认可模式可以为临床医生判断个体是否患有DID或是否在伪装提供有用信息。
