title: Severity of personality disorders and domains of general personality dysfunction related to attachment.
abstract: This is the first study to link attachment to both severity of total DSM-IV personality disorder (PD) traits and domains of general personality dysfunction, using a sample of 72 inpatients from New York City. We assessed a measure of global PD severity and the core domains of personality functioning using the severity indices of personality problems (SIPP-118). Attachment was measured with the experience in close relationships-revised (ECR-R) and the relationship style questionnaire (RSQ). Global PD severity correlated most strongly with attachment anxiety (r = 0.65). Regression of the SIPP-118 domains on attachment produced models that accounted for a substantial proportion of variance in those scales (R(2) ranging from 28.2 to 54.2%). SIPP-118 relational capacities were the strongest predictor of ECR-R avoidance (β = -0.88) and anxiety (β = -0.58), as well as RSQ secure (β = 0.53) and fearful (β = -0.65). In conclusion, insecure attachment strongly related to the severity of global PD traits and specifically to relational capacities, which are a higher-order domain of general personality dysfunction. These findings provide further evidence that interpersonal problems are at the core of PDs and that attachment could constitute an important mediator of the social dysfunction in persons with personality pathology.
