Siblings as Selfobjects in Childhood: An Interview Study of Factors and Consequences

This study explores the factors psychotherapists working with adult clients identify as contributing to their clients' use in childhood of relationships with siblings to meet selfobject needs or the use of clients by their siblings for selfobject purposes in childhood, and the consequences of this to the children's intrapsychic development as evidenced in their adult psychotherapy. Using interviews with six psychotherapists practicing within the framework of self psychology, this research determines that the emotional and physical unavailability of parents was a common factor causing children to use their siblings for selfobject purposes. The research also explores the lasting impact of these selfobject ties on the psychological development of both the child using a sibling for selfobject purposes and the child who serves this function for another, as well as the role of psychotherapy in understanding these relationships. These findings give psychotherapists from a variety of disciplines, including social work, an enhanced conceptual framework from which to consider the role of siblings in psychological development.
