Abstract：
Traditionally, narcissistic characteristics are considered relatively stable, although clinical accounts and recent research show that additional narcissistic states are variable and fluctuate in actuality. Narcissism research tends to focus on cross-sectional, group-based, trait approaches. Momentary ecological assessments allow one to discover individuals\' true colors by observing narcissistic experiences while they unfold in real-time and real-world settings. Within momentary ecological assessments, inspecting single cases enables insight into individual dynamics and presentations. Consequently, this research collected grandiose and vulnerable narcissistic trait and state data 10 times a day for 6 days. Based on the highest trait scores, two individual cases are presented per category: predominantly grandiose narcissistic, predominantly vulnerable narcissistic, and combined narcissistic. Overall, the descriptions provide evidence for the dynamics within and between grandiose and vulnerable narcissistic states. Further, broad patterns for each narcissistic dimension were uncovered, in which the grandiose subdimension experienced mainly grandiosity, and the vulnerable and combined subdimensions experienced both grandiosity and vulnerability. Out of the three, the combined subdimension experienced the highest instability and levels of daily vulnerability. However, each individual case showed unique fluctuation patterns that highlight the importance of personalized, real-life assessments in research and clinical care.
摘要：
传统上,自恋特征被认为是相对稳定的，尽管临床报道和最近的研究表明，额外的自恋状态是可变的，并且实际上是波动的。自恋研究往往集中在横断面上，基于群体，特质方法。短暂的生态评估使人们能够通过观察自恋的经历来发现个体的真面目，同时它们在实时和现实世界的环境中展开。在短暂的生态评估中，检查单个案例可以洞察个人动态和演示。因此,这项研究收集了浮夸和脆弱的自恋特征和状态数据，每天10次，共6天。基于最高的特质分数，每个类别列出了两个个案：主要是浮夸的自恋，主要是脆弱的自恋，结合了自恋。总的来说,这些描述为宏伟和脆弱的自恋状态内部和之间的动态提供了证据。Further,揭示了每个自恋维度的广泛模式，其中宏伟的子维度主要经历宏伟，脆弱和合并的子维度经历了宏伟和脆弱性。在这三个人中，组合子维度经历了最高的不稳定性和日常脆弱性水平。然而,每个个案都表现出独特的波动模式，突出了个性化的重要性，研究和临床护理中的现实生活评估。
