Parental bonding and personality pathology assessed by clinician report.

The present study focused on the link between parental bonding and personality pathology. We developed a clinician-report version of the Parental Bonding Instrument (PBI; Parker, Tupling, and Brown, 1979), which 203 clinicians applied to a randomly selected patient in their care. The goal of the study was to examine the reliability and validity of a clinician-report PBI, and to provide a preliminary examination of the relation between personality disorder (PD) symptoms and parental bonding in a national sample of patients in treatment in the community. Factor analysis yielded two factors (parental rejection/care and parental overprotection) for each parent, which had high internal consistency (coefficient alphas all >.80). The factor structure of the clinician-report measure strongly resembled the factor structure of the widely used self-report instrument. Parental bonding as assessed by clinician report showed coherent patterns of association with PD diagnoses, which resembled those found in other samples. Maternal rejection/care showed a particular link to borderline PD (BPD), and remained a significant predictor of BPD along with sexual abuse and physical abuse in multiple regression analysis. These data, along with others from recent studies using clinicians as informants, suggest that clinicians can provide reliable and valid data when their observations are quantified using psychometrically sound instruments. Clinician-report methods may provide a useful complement to studies of personality disorders that rely primarily on self-reports or structured interviews.
