ABSTRACT Sibling relationships are typically long-lasting, providing opportunities for critical social support throughout a lifetime. This study examined how perceptions of sibling support differ for closest and least close sibling relationships, and how support in one sibling relationship can be associated with satisfaction in the other. Adults with at least two siblings answered questions about closest and least close sibling support and relationship satisfaction. Multilevel modeling results indicated that support in one sibling relationship is associated with relationship satisfaction in another sibling relationship. The types of support that contributed to relationship satisfaction differed for the closest and least close sibling but communicated support availability was important to both types of relationships. Implications for understanding sibling triad dynamics are discussed.

相互依赖的兄弟姐妹：最亲密和最不亲密的兄弟姐妹社会支持与兄弟姐妹关系满意度之间的关联

摘要 兄弟姐妹关系通常是持久的，为终生提供重要社会支持的机会。本研究调查了对兄弟姐妹支持的看法在最亲密和最不亲密的兄弟姐妹关系中有何不同，以及一个兄弟姐妹关系中的支持如何与另一个兄弟姐妹的满意度相关联。至少有两个兄弟姐妹的成年人回答了关于最亲密和最不亲密的兄弟姐妹支持和关系满意度的问题。多级建模结果表明，一种兄弟关系中的支持与另一种兄弟关系中的关系满意度相关。最亲密和最不亲密的兄弟姐妹之间关系满意度的支持类型不同，但沟通支持的可用性对两种类型的关系都很重要。
