Psychological risk factors and self-mutilation in male patients with BPD.

The purpose of this study was to determine whether or not self-mutilation in patients with personality disorders is related to other psychological risk factors, dissociation or diagnosis. The sample included 61 subjects with borderline personality disorder and 60 subjects with nonborderline personality disorder; 32 subjects with borderline personality disorder reported self-mutilation. Psychological risk factors were measured through histories of childhood sexual abuse, physical abuse and separation or loss as well as through scores on the Parental Bonding Index. Dissociation was measured by the Dissociative Experiences Scale. There were no relationships between any of the psychological risk factors and self-mutilation. Subjects who mutilated themselves had higher scores on the Dissociative Experiences Scale in univariate analysis but the scores in multivariate analyses dissociation did not discriminate between subjects who mutilated themselves and those who did not. The results do not support the theory that abuse and dissociation account for self-mutilation in the personality disorders.
