Childhood maltreatment (CM) is thought to be linked to adult narcissistic traits. However, it remains unclear how CM is associated with each type of narcissism, vulnerable and grandiose, and what mechanism mediates these links. One potential candidate is dissociation. This study examines the relations among CM, dissociation, vulnerable narcissism, and grandiose narcissism. A total of 322 women completed self-reported questionnaires assessing CM, dissociation, vulnerable narcissism, and grandiose narcissism. To examine the relations among CM, dissociation, and each type of narcissism, we performed Pearson's correlations and mediation analyses. In secondary analyses, we conducted latent class analyses to classify different types of CM and to assess their relations with the study variables. We found small to moderate correlations between CM and vulnerable narcissism, ( = .35, < .001) and CM and grandiose narcissism ( = .2, < .001), with the former association being greater than the latter ( = -3.25, < .001). Dissociation was found to mediate the link between CM and each type of narcissism ( < .001). Results suggest that CM may play a role in the etiology of vulnerable and grandiose narcissism, and that dissociation links CM to each type of narcissism. Findings highlight that CM may lead to different responses in terms of narcissism-through the same mediation process.
儿童虐待（CM）被认为与成人自恋特质有关。然而，目前尚不清楚 CM 与每种自恋类型（脆弱型和夸大型）有何关联，以及何种机制介导了这些关联。一个潜在的候选者是解离。本研究探讨了 CM、解离、脆弱型自恋和夸大型自恋之间的关系。共有 322 名女性完成了自我报告问卷，评估了 CM、解离、脆弱型自恋和夸大型自恋。为了检验 CM、解离与每种自恋类型之间的关系，我们进行了 Pearson 相关分析和中介分析。在二次分析中，我们进行了潜在类别分析，以对不同类型的 CM 进行分类，并评估它们与研究变量的关系。我们发现 CM 与脆弱型自恋（ =.35， <.001）和 CM 与夸大型自恋（ =.2， <.001）之间存在小到中等程度的相关，前者的关联大于后者（ = -3.25， <.001）。解离被发现中介了 CM 与每种自恋类型之间的联系（ <.001）。研究结果表明，CM 可能在脆弱型和夸大型自恋的发病机制中起作用，而解离将 CM 与每种自恋类型联系起来。研究结果强调，CM 可能通过相同的中介过程导致不同的自恋反应。
