Past literature has documented a linkage between entitlement and interpersonal tension, primarily in romantic relationships. However, there is a lack of research investigating the impact of entitlement on sibling relationships. Guided by the agency model of narcissism and adult development literature, this study conceptualized relational entitlement as one form of state narcissism and examined the actor and partner effects of relational entitlement on perceived sibling conflict as well as the moderating effects of financial dependence on parents. Participants were 136 emerging adult sibling dyads (older sibling Mage = 22.20, SD = 2.35; younger sibling Mage = 19.54, SD = 1.55). Results indicated that younger siblings' (not older siblings') relational entitlement was positively associated with both their own and their siblings' perceptions of conflict. Moreover, younger siblings' financial dependence buffered the actor association between younger siblings' relational entitlement and perceived conflict. These findings suggest that emerging adult siblings' developmental status of financial dependence provides a nuanced context for understanding the actor and partner effects of relational entitlement on sibling conflict. The discussion focuses on the role of self‐inflated social comparison in emerging adult sibling conflict and how the developmental characteristics of older and younger siblings shape the above associations.

新兴成年兄弟姐妹的关系权利和冲突：经济依赖父母的调节作用

过去的文献记录了权利与人际紧张之间的联系，主要是在浪漫关系中。然而，缺乏研究调查权利对兄弟姐妹关系的影响。在自恋代理模型和成人发展文献的指导下，本研究将关系权利概念化为国家自恋的一种形式，并研究了关系权利对行为者和伴侣对兄弟姐妹冲突的影响以及经济依赖对父母的调节作用。参与者是 136 名即将成年的兄弟姐妹（年长的兄弟姐妹）中号年龄= 22.20，标准差 = 2.35；弟弟妹妹中号年龄= 19.54，标准差 = 1.55）。结果表明，弟弟妹妹（而不是哥哥姐姐）的关系权利与他们自己和兄弟姐妹对冲突的看法呈正相关。此外，弟弟妹妹的经济依赖缓冲了弟弟妹妹的关系权利和感知冲突之间的行动者关联。这些发现表明，新兴成年兄弟姐妹的经济依赖的发展状况为理解关系权利对兄弟姐妹冲突的行为者和伴侣的影响提供了微妙的背景。讨论的重点是自我膨胀的社会比较在新出现的成人兄弟姐妹冲突中的作用，以及年长和年幼的兄弟姐妹的发展特征如何塑造上述关联。
