Abstract

The current study focuses on the development and validation of a scoring procedure for malignant narcissism using the Personality Inventory for DSM-5, a self-report measure of Criterion B from the Alternative Model for Personality Disorders. In Study 1, a prototype matching approach was used to aggregate ratings from 15 clinicians specializing in personality disorder treatment and/or assessment. Indices of inter-rater agreement and inter-rater reliability revealed high convergence as to the most important maladaptive facets for malignant narcissism. The scoring procedure, based on additive counts for score computation, included eleven Criterion B facets covering core features of malignant narcissism. Study 2 evaluated the criterion and incremental validity of the scoring procedure in a sample of 288 patients from a personality disorder treatment clinic, as well as in a sample of 1103 participants from the community. In both samples, results from nonparametric mean comparisons, receiver operating characteristic curves, bivariate Pearson correlations, and hierarchical multiple linear regressions showed significant associations between malignant narcissism and broader components of personality functioning, as well as with relevant emotional, relational, and/or behavioral features. This new scoring procedure is a simple and valid method for measuring malignant narcissism, and is suitable for clinical and research settings.

摘要

目前的研究重点是使用 DSM-5 人格量表开发和验证恶性自恋评分程序，DSM-5 是人格障碍替代模型中标准 B 的自我报告测量。在研究 1 中，使用原型匹配方法汇总了 15 名专门从事人格障碍治疗和/或评估的临床医生的评分。评估者间一致性和评估者间可靠性的指数表明，恶性自恋最重要的适应不良方面高度趋同。评分程序基于分数计算的加性计数，包括十一个标准 B 方面，涵盖恶性自恋的核心特征。研究 2 在来自人格障碍治疗诊所的 288 名患者样本以及来自社区的 1103 名参与者样本中评估了评分程序的标准和增量有效性。在这两个样本中，非参数均值比较、接受者操作特征曲线、双变量 Pearson 相关性和分层多元线性回归的结果表明，恶性自恋与人格功能的更广泛组成部分以及相关的情绪、关系和/或行为之间存在显着关联特征。这种新的评分程序是一种简单有效的恶性自恋测量方法，适用于临床和研究环境。非参数均值比较、接受者操作特征曲线、双变量皮尔逊相关系数和层次多元线性回归的结果表明，恶性自恋与人格功能的更广泛组成部分以及相关的情绪、关系和/或行为特征之间存在显着关联。这种新的评分程序是一种简单有效的恶性自恋测量方法，适用于临床和研究环境。非参数均值比较、接受者操作特征曲线、双变量皮尔逊相关系数和分层多元线性回归的结果表明，恶性自恋与人格功能的更广泛组成部分以及相关的情绪、关系和/或行为特征之间存在显着关联。这种新的评分程序是一种简单有效的恶性自恋测量方法，适用于临床和研究环境。
