The Narcissistic Personality Inventory (NPI) is commonly used in empirical studies of narcissism. Few population-based studies have been published. Our aim was to do a confirmatory factor analysis (CFA) of the NPI 29 item version with a four-factor structure, in two population-based samples and in a patient sample, and present normative population-based data. The NPI-29 was filled in by 324 respondents from the Norwegian population, 231 from the Swedish population and 167 Norwegian psychiatric patients. The four-factor structure of the NPI-29 with Leadership/Power, Exhibitionism/Self-admiration, Superiority/Arrogance and Uniqueness/Entitlement was reproduced in these samples. The CFA models showed good fit indices in all samples. Mean scores on the NPI-29 and four subscales hardly differed between the samples. For the NPI-29 total score and factors, few significant differences were observed. CFA of the samples supported the factor structure of the NPI-29 formerly identified by principal component analysis of the Swedish population sample.
自恋人格问卷（NPI）常用于自恋的实证研究。基于人群的研究发表较少。我们的目的是在两个基于人群的样本和一个患者样本中，对具有四因素结构的29项版本的NPI进行验证性因素分析（CFA），并呈现基于人群的规范数据。来自挪威人群的324名受访者、瑞典人群的231名受访者和167名挪威精神病患者填写了NPI - 29。在这些样本中再现了NPI - 29具有领导力/权力、暴露癖/自我欣赏、优越感/傲慢和独特性/权利的四因素结构。CFA模型在所有样本中均显示出良好的拟合指数。样本之间NPI - 29及其四个子量表的平均分几乎没有差异。对于NPI - 29总分和各因素，观察到的显著差异较少。样本的CFA支持了之前通过对瑞典人群样本进行主成分分析所确定的NPI - 29的因素结构。
