Maternal Representations of Patients with Schizophrenia as Measured by the Parental Bonding Instrument

Maternal perceptions were assessed, using the Parental Bonding Instrument (PBI) in 19 subjects with schizophrenia, 14 subjects with borderline personality disorder and 15 non-clinical subjects. Subjects with schizophrenia and subjects with borderline personality disorder reported significantly less care and more overprotection than did non-clinical subjects. No significant differences were found in representations by subjects with schizophrenia and subjects with borderline personality disorders. To the extent that the reported negative maternal behaviour gives a true picture of childhood and adolescent experiences, it does not seem to be specific for schizophrenia, but may be one factor in the development of severe mental disorders.
