The Trifurcated Model of Narcissism (TriMN) has received growing attention in the scientific study of narcissistic traits, as it provides a clear and clinically useful distinction of the three core elements of narcissistic personalities: agentic extraversion (AE), narcissistic antagonism (NA), and narcissistic neuroticism (NN). So far, the Five-Factor Narcissism Inventory (FFNI) and its abbreviations-for example, the recently introduced brief form (FFNI-BF)-represent the only measures that allow for a direct and simultaneous assessment of these traits. Distinct parts of the TriMN have also been measured by other narcissism scales, however, including the Narcissistic Admiration and Rivalry Questionnaire (NARQ) or the Hypersensitive Narcissism Scale (HSNS). It remains unclear to what extent trait estimates provided by these alternative measures overlap and under which circumstances they can be used interchangeably. Here, we present a model-driven combination of NARQ and HSNS items that may serve as a valuable, economic tool to assess the three narcissism dimensions. In two studies (accumulated N = 2,266, 1,673 female, 580 male, 13 diverse), we show that the NARQ/HSNS and the FFNI-BF access virtually the same presentations of AE, NA, and NN, whereby the combined NARQ/HSNS outperforms the FFNI-BF in terms of structure, theory-consistent relations among (latent) narcissistic traits, and predictive validity with respect to personality pathology. Our research provides new insights on the assessment of narcissistic traits according to the increasingly popular TriMN and can inform future research on its dimensions.

一个衡量的问题？评估自恋的三个维度。

自恋三叉模型（TriMN）在自恋特质的科学研究中受到越来越多的关注，因为它对自恋人格的三个核心要素提供了清晰且在临床上有用的区分：代理外向性（AE）、自恋对抗性（NA）、和自恋神经质（NN）。到目前为止，五因素自恋量表（FFNI）及其缩写——例如最近推出的简短形式（FFNI-BF）——是唯一可以直接、同时评估这些特征的措施。然而，TriMN 的不同部分也可以通过其他自恋量表来测量，包括自恋钦佩和竞争问卷 (NARQ) 或超敏感自恋量表 (HSNS)。目前尚不清楚这些替代措施提供的性状估计在多大程度上重叠，以及在什么情况下它们可以互换使用。在这里，我们提出了 NARQ 和 HSNS 项目的模型驱动组合，可以作为评估三个自恋维度的有价值的经济工具。在两项研究中（累计 N = 2,266，1,673 名女性，580 名男性，13 名不同的人），我们表明 NARQ/HSNS 和 FFNI-BF 访问几乎相同的 AE、NA 和 NN 表现，其中组合的 NARQ/HSNS在结构、（潜在）自恋特征之间的理论一致性关系以及人格病理学的预测有效性方面优于 FFNI-BF。我们的研究为根据日益流行的 TriMN 评估自恋特质提供了新的见解，并可为未来对其维度的研究提供信息。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
