Abstract
Dissociative Identity Disorder (DID), formerly Multiple Personality Disorder, involves two or more distinct identities controlling behaviour, stemming from trauma-related dissociation. Understanding DID's cognitive, neural, and psychometric aspects remains a challenge, especially in distinguishing genuine cases from malingering. We present a case of a DID patient with nine identities, evaluated to rule out malingering. Using the Millon Index of Personality Styles, we assessed the primary and two alternate identities, revealing marked differences. High consistency scores support validity. We suggest employing personality inventories beyond symptomatology to characterise dissociative identities' consistency and adaptation styles, aiding in malingering assessments in future studies.
分离性身份识别障碍（DID），前身为多重人格障碍，涉及两个或多个不同的身份控制行为，源于与创伤相关的分离。了解 DID 的认知、神经和心理测量方面仍然是一项挑战，尤其是在区分真实病例和装病病例方面。我们介绍了一例具有九种身份的 DID 患者，通过评估排除了装病的可能性。我们使用米隆人格类型指数（Millon Index of Personality Styles）对主要身份和两个备用身份进行了评估，结果发现了明显的差异。高一致性得分证明了其有效性。我们建议采用症状学以外的人格清单来描述分离性身份的一致性和适应风格，从而在未来的研究中帮助进行弊病评估。
期刊介绍：
Neurocase is a rapid response journal of case studies and innovative group studies in neuropsychology, neuropsychiatry and behavioral neurology that speak to the neural basis of cognition. Four types of manuscript are considered for publication: single case investigations that bear directly on issues of relevance to theoretical issues or brain-behavior relationships; group studies of subjects with brain dysfunction that address issues relevant to the understanding of human cognition; reviews of important topics in the domains of neuropsychology, neuropsychiatry and behavioral neurology; and brief reports (up to 2500 words) that replicate previous reports dealing with issues of considerable significance. Of particular interest are investigations that include precise anatomical localization of lesions or neural activity via imaging or other techniques, as well as studies of patients with neurodegenerative diseases, since these diseases are becoming more common as our population ages. Topic reviews are included in most issues.
