Boundary Ambiguity and Borderline Personality Traits: Implications for Treatment for Adolescent Girls in Foster Care

This article explores the relationship between boundary ambiguity and borderline personality traits in adolescent girls in foster care. Boundary ambiguity is a family systems concept: family members are uncertain about who is in or out of the family-in either psychological or physical presence or absence. In foster care, it can be assumed that an adolescent girl has experienced trauma significant enough to be removed from her family. The connection between early childhood trauma and attachment disruption in addition to the connection between insecure/disorganized attachment and borderline personality disorder leads to the conclusion that these same adolescents are at high risk for developing borderline personality traits. The sample consists of 40 caseworkers from New England's child protection departments and therapists from residential programs working with adolescent girls. They completed the Shedler-Westen Assessment Procedure for Adolescents to determine the presence of personality disruption as well as a variation of Pauline Boss's Boundary Ambiguity Scale #1, and demographic questionnaires. The results find a significant correlation between boundary ambiguity and borderline personality traits. These findings provide directions for future research in clinical treatment and child welfare policy making.
