Perceived Caretaker Malevolence During Childhood Reported by Borderline Patients and Personality-Disordered Comparison Subjects: Description and Prediction.

This study has two purposes. The first is to assess the rates of childhood malevolence by caretakers reported by a well-defined sample of inpatients with borderline personality disorder (BPD) and comparison subjects with other personality disorders. The second purpose is to determine the relationship between reported malevolence of caretakers and possible risk factors for this experience. Two reliable interviews were administered to 290 borderline inpatients and 72 personality-disordered comparison subjects to address these aims. Malevolence was reported by a significantly higher percentage of borderline patients than comparison subjects (58% vs. 33%). In multivariate analyses, severity of other forms of abuse, severity of neglect, and a family history of a dramatic cluster personality disorder were found to significantly predict perceived malevolence. Taken together, the results of this study suggest that experiencing malevolence is common and distinguishing for BPD, and that the risk factors for reported childhood malevolence are multifactorial in nature.

Reported childhood onset of self-mutilation among borderline patients.

The purpose of this study was to determine the percentage of borderline patients who first engaged in self-mutilation as children and to compare the parameters of their self-harm to those of borderline patients who first harmed themselves at an older age. Two hundred and ninety inpatients meeting both Revised Diagnostic Interview for Borderlines (DIB-R; Zanarini, Gunderson, Frankenburg, & Chauncey, 1989) and Diagnostic and Statistical Manual of Mental Disorders (3rd ed. ref.) (DSM-III-R; APA, 1987) criteria for borderline personality disorder were interviewed about their history of self-mutilation. Of the 91% with a history of self mutilation, 32.8% reported first harming themselves as children (12 years of age or younger), 30.2% as adolescents (13-17 years of age), and 37% as adults (18 or older). Using logistic regression analyses and controlling for baseline age, it was found that those with a childhood onset reported more episodes of self-harm, a longer duration of self-harm, and a greater number of methods of self-harm than either those with an adolescent or adult onset to their self-mutilation. The results of this study suggest that a sizable minority of borderline patients first engage in self-harm as children and that the course of their self-mutilation may be particularly malignant.
