In this grounded theory study, we examined the processes through which 25 young adult stepchildren developed relationships with 71 stepsiblings. We also examined the interpersonal and familial contexts within which stepsibling relationships were formed. We identified six distinct types of stepsibling connections: (a) strangers, (b) distant acquaintances, (c) rivals, (d) ambivalent friends or frenemies, (e) friends, and (f) siblings. These relationship types varied in emotional closeness and quality and were qualitatively different in how they developed and were maintained. These stepsibling types also differed in their interpersonal contexts, particularly in interactions and relationships with parents and stepparents.

在这项扎根理论研究中，我们研究了 25 名年轻成年继子女与 71 名继兄弟姐妹发展关系的过程。我们还研究了形成继兄弟关系的人际关系和家庭环境。我们确定了六种不同类型的继兄弟姐妹关系：（a）陌生人，（b）远方的熟人，（c）竞争对手，（d）矛盾的朋友或敌人，（e）朋友，和（f）兄弟姐妹。这些关系类型在情感亲密程度和质量上各不相同，并且在它们的发展和维持方式上也存在质的不同。这些继兄弟姐妹类型在人际关系方面也有所不同，特别是在与父母和继父母的互动和关系方面。
