Interpersonal Problems in Parents and Adolescent Borderline Personality Disorder Features.

Research shows that parental personality pathology is associated with borderline personality disorder features and internalizing/externalizing symptoms in offspring. However, studies have been limited by DSM-IV-based assessments of parental personality pathology. The authors leveraged evidence that interpersonal problems described by the Interpersonal Circumplex align with Criterion A of the DSM-5 Alternative Model for Personality Disorders and therefore used a measure of interpersonal problems to capture parental personality pathology. The authors hypothesized that parental interpersonal problems would be associated with a latent variable of borderline features in adolescent offspring. They also examined whether this relation with offspring borderline features existed above and beyond relations with offspring internalizing/externalizing symptoms, age, and gender. The sample included 524 inpatient adolescents (Mage = 15.31, 62.4% female) and their parents (80.5% female). Parental interpersonal problems demonstrated unique relationships with adolescent borderline features and externalizing symptoms, but not internalizing symptoms. Implications of the results, limitations, and future directions are discussed.
