The Pathological Narcissism Inventory (PNI) is a popular measure and the first to attempt to tap into both grandiose and vulnerable narcissism (GN/VN). However, data have raised questions as to whether it appropriately formulates GN and differentiates it from VN. In this study, we examined the Brief-PNI's structure and construct validity, by using a novel model based on the theoretical notion of GN and VN sharing core features. Participants ( = 1,061) completed the Brief-PNI, and psychological distress and social avoidance questionnaires. Results showed a better fit and differentiation of GN and VN for a model with cross-loading of shared first-order factors on GN and VN, compared with the traditional PNI structure. We concluded that the Brief-PNI can offer an appropriate formulation and differentiation of VN and GN, provided that their shared variance is considered.
病理性自恋量表（PNI）是一种流行的测量工具，也是第一个尝试同时测量夸大性和脆弱性自恋（GN/VN）的量表。然而，数据提出了一些问题，即它是否适当地构建了 GN 并将其与 VN 区分开来。在这项研究中，我们通过使用基于 GN 和 VN 共享核心特征的理论概念的新模型，检验了Brief-PNI 的结构和构念效度。参与者（n=1061）完成了Brief-PNI 以及心理困扰和社交回避问卷。结果表明，与传统 PNI 结构相比，对于共享一阶因子在 GN 和 VN 上具有交叉负荷的模型，GN 和 VN 的拟合度更好，区分度也更好。我们得出结论，只要考虑到它们的共享方差，Brief-PNI 就可以提供对 VN 和 GN 的适当构建和区分。
