The relationship of early maternal separation to borderline personality in children and adolescents: a pilot study.

The author compared 14 child and adolescent borderline patients, diagnosed by the criteria of Gunderson and Singer (1), with a control population for history of separation from the mother or significant caretaker before age 10. The borderline patients experienced a statistically greater number of separations than the psychotic controls, the nonpsychotic psychiatric controls, and the nonpsychiatrically-referred delinquent controls before age 5 but not between ages 5 and 10. The author concludes that the study provides statistical support for the theoretic role of disruption of the early infant-mother bond in borderline pathology.
