Borderline personality traits; Eigenvalue spectrum of correlation network

Borderline personality influenced by numerous factors is considered as a complex network. Purpose of the study was to conduct a research on borderline personality traits (BPT) using network dynamics for research on factors influencing BPT.

The statistical population included monozygotic and dizygotic twins (N=500 participants; Mage=23.46; 74.40% female; Iranian). The research instruments were self-report for participants. We used a threshold for correlations to remove links which represented weak relations. After creating a sparse network, inverse participation ratio (IPR) method was used to extract affective nodes.

In total sample and monozygotic twins, nodes of secure attachment to mother and father had a profound effect on network stability (Prevention of sings) and node of secure attachment to father had the greatest impact on the given stability among dizygotic twins. Nodes of interpersonal problems, emotional neglect, and insecure attachment to father were among the most important ones affecting all groups in network no stability (Moving towards sings).

Given the dominance of environmental factors within threshold conditions, the influence of environment on heritability for BPT was confirmed.
