The Narcissistic Personality Inventory (NPI) is widely used in social and personality psychology. The present study validates a French version of the NPI (NPI-Fr) for use with young adults. Respondents (N = 1275, Mage = 21.83, SD = 4.97) completed the NPI and two other convergent measures (Rosenberg Self-Esteem Scale and French version of the Big Five Inventory) for three validation steps. Exploratory factor analyses yielded evidence for a structure with either two (Power/Authority, Exhibitionism/Self-Admiration) or four (Leadership/Authority, Grandiosity/Exhibitionism, Special Person, Exploitativeness/Entitlement) first-order factors for the NPI. Confirmatory factor analyses supported the 33-item four-factor model, with moderate model fit indices (&khgr;2/df = 2.04, RMSEA = .058, CFI = .90, GFI = .85). We found significant positive correlations (r = .11 to .44) with self-esteem, Extraversion, and Openness, and a negative correlation with Neuroticism (r = –.09 to –.21). There was high internal consistency, with a reliability coefficient of &agr; = .73 to .93, while test–retest reliability at 4 weeks was satisfactory. Our results confirm the psychometric quality of the questionnaire for French young adults.

法语版年轻人自恋人格量表的心理测量特性

自恋人格量表（NPI）广泛用于社会和人格心理学。本研究验证了法语版本的 NPI (NPI-Fr) 可用于年轻人。受访者（N = 1275，Mage = 21.83，SD = 4.97）完成了三个验证步骤的 NPI 和其他两项收敛措施（罗森伯格自尊量表和法语版大五问卷）。探索性因素分析为 NPI 具有两个（权力/权威、表现主义/自尊）或四个（领导力/权威、浮夸/表现主义、特殊人物、剥削性/权利）一阶因素的结构提供了证据。验证性因子分析支持 33 项四因子模型，模型拟合指数适中（&khgr;2/df = 2.04，RMSEA = .058，CFI = .90，GFI = .85）。我们发现与自尊、外向性和开放性显着正相关（r = .11 至 .44），与神经质呈负相关（r = –.09 至 –.21）。内部一致性高，信度系数&agr; = .73 至 .93，而 4 周时的重测信度令人满意。我们的结果证实了法国年轻人问卷的心理测量质量。
