Higher indexes of childhood trauma in borderline personality disorder compared with bipolar disorder.

OBJECTIVES

Comparison of the frequency of childhood traumatic events between agroup of patients with bipolar disorder (BD), borderline personality disorder (BPD) and healthy persons.

METHODS

The study included 35 patients (10 male, 25 female) with BD, hospitalized in the Department of Adult Psychiatry in Poznań, the Neuropsychiatric Hospital in Kościan and the Medical Centre in Milicz, as well as 35 patients (9 male, 26 female) with BPD under the care of the Józef Babinski Hospital in Kraków. Seventy-one healthy persons (22 male, 49 female) constituted a control group. The Polish version of the Childhood Trauma Questionnaire (CTQ) was used.

RESULTS

In both clinical groups, no gender differences as to the CTQ indexes were found. Patients from both groups hadmorefrequentchildhoodtraumacomparedwith controlsubjects. Patients with BPD showed significantly higher CTQ indexes than those with BD. .

CONCLUSIONS

The obtained results indicate significantly more frequent experience of traumatic events in childhood in patients with BPD compared with BD. This is discussed in the context of the pathogenesis and treatment of both conditions. It is probable that in BPD childhood trauma plays the biggest role among all psychiatric disturbances.
