Patterns of Stepsibling Relationship Development

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.
