Abstract

Previous research has shown that grandiose narcissism, particularly its agentic facet, is positively associated with testosterone in men. In two studies (N₁ = 186; N₂ = 269) we investigated potential hormonal underpinnings of narcissism in women. We examined the associations between facets of narcissism, estradiol levels measured from blood samples, self-reported estradiol, and self-perceived attractiveness. We failed to find a significant association between agentic narcissism and objectively measured estradiol. However, women with higher grandiose narcissism perceived themselves as having elevated estradiol levels and reported feeling more attractive. In women, the effects of estradiol on personality-related behaviors may be context-dependent and temporally variable. Moreover, since estradiol fluctuates across the menstrual cycle, potential associations with state narcissism may be more evident around the fertile (ovulatory) phase.

女性自恋的荷尔蒙基础：从血液和自我报告中测量雌二醇的作用

先前的研究表明，浮夸型自恋，尤其是其主观方面，与男性的睾丸激素呈正相关。在两项研究中（N1 = 186; N2 = 269），我们调查了女性自恋的潜在荷尔蒙基础。我们研究了自恋的各个方面、从血液样本中测量的雌二醇水平、自我报告的雌二醇水平和自我感知的吸引力之间的联系。我们没有发现主观自恋和客观测量的雌二醇之间有显著的联系。然而，浮夸型自恋程度较高的女性认为自己的雌二醇水平较高，感觉自己更有吸引力。在女性中，雌二醇对人格相关行为的影响可能是环境依赖的，并且是暂时可变的。此外，由于雌二醇在整个月经周期中波动，与状态自恋的潜在关联可能在排卵期更为明显。

The subject matter includes treatments of genetic, physiological, motivational, learning, perceptual, cognitive, and social processes of both normal and abnormal kinds in human and animal subjects. Features: • Papers that present integrated sets of studies that address significant theoretical issues relating to personality. • Theoretical papers and critical reviews of current experimental and methodological interest. • Single, well-designed studies of an innovative nature. • Brief reports, including replication or null result studies of previously reported findings, or a well-designed studies addressing questions of limited scope.
