Previous research suggested that narcissism is associated with infidelity and reduced commitment in relationships. However, the majority of studies supporting this association were conducted among individuals and did not examine dyadic paths and also conceptualized and measured narcissism as a global variable, lacking a nuance perspective of the two traits of narcissism (i.e., grandiose and vulnerable). The present study sought to examine attitudes toward infidelity from a dyadic perspective, using narcissism personality traits (grandiose and vulnerable) as predictors. The effect of narcissism personality traits on attitudes toward infidelity was investigated among 135 couples ( = 270) in enduring relationships. To assess whether attitudes toward infidelity were explained by grandiose narcissism and vulnerable narcissism, we used multivariate multilevel statistical model for matched pairs to evaluate the effect of each partner's characteristics on their own (actor effect) and their partner's (partner effect) attitudes. The results indicate that females' attitudes toward infidelity were positively associated with their own grandiose narcissism and vulnerable narcissism and negatively associated with their partner's grandiose narcissism. Males' attitudes toward infidelity were positively associated with both their own and their partner's vulnerable narcissism but not with their or their partner's grandiose narcissism. The results highlighted the importance of studying different aspects of narcissism in relation to dyadic processes within intimate relationships in general and regarding infidelity in particular. Our findings suggest that more or less favorable attitudes toward infidelity depend not only on the individual's narcissistic traits but on his/her partner's grandiosity and vulnerability as well.

先前的研究表明，自恋与不忠和关系承诺减少有关。然而，支持这种关联的大多数研究都是在个体中进行的，没有考察对偶路径，也没有将自恋概念化为一个全局变量，缺乏对自恋的两个特征（即夸大和脆弱）的细微视角。本研究试图从对偶的角度研究对不忠的态度，将自恋人格特质（夸大和脆弱）作为预测指标。在持久关系中的 135 对夫妻（=270）中，研究了自恋人格特质对不忠态度的影响。为了评估对不忠的态度是否可以用夸大的自恋和脆弱的自恋来解释，我们使用多元多层统计模型对配对进行了评估，以评估每个伴侣的特征对自己（演员效应）和他们伴侣（伴侣效应）的态度的影响。结果表明，女性对不忠的态度与其自身的夸大型自恋和脆弱型自恋呈正相关，与伴侣的夸大型自恋呈负相关。男性对不忠的态度与其自身和伴侣的脆弱型自恋呈正相关，但与他们或伴侣的夸大型自恋无关。这些结果强调了在一般亲密关系的对偶过程中研究自恋的不同方面以及特别是在不忠方面的重要性。我们的研究结果表明，对不忠的态度或多或少的有利，不仅取决于个人的自恋特质，还取决于他/她伴侣的夸大和脆弱。（PsycInfo 数据库记录（c）2023 APA，保留所有权利）。
