To date, adolescent and adult narcissism research are independent research branches with almost no cross-talk. In the current paper, we argue that it is possible to merge them. The study was completed by adolescents (N = 269) three times during one year period and we compared their scores with adult population (N = 351). Further, we evaluated whether the two-dimensional model of narcissism fits the data from adolescents and whether is invariant in comparison to the adults. Third, we analysed whether narcissism in adolescence is stable. Finally, we scrutinized whether the pathways underlying the link of narcissistic personality to being liked are the same in adolescent as reported in adult narcissism. We have found support for linking adolescent and adult narcissism.

迄今为止，青少年和成人自恋研究是独立的研究分支，几乎没有相声。在当前的论文中，我们认为可以合并它们。该研究由青少年 ( N  = 269) 在一年内完成3 次，我们将他们的分数与成年人 ( N  = 351) 进行了比较。此外，我们评估了自恋的二维模型是否适合青少年的数据，以及与成年人相比是否具有不变性。第三，我们分析了青春期的自恋是否稳定。最后，我们仔细研究了自恋人格与被喜欢的联系背后的途径是否与成人自恋中报告的青少年相同。我们已经找到了将青少年和成人自恋联系起来的支持。
