Significant research has been dedicated to the relation between childhood adversities and the development of personality structure. The present research aims to contribute to this exploration using a data-driven network approach. Specifically, the study psychometrically investigates the relationships between personality organization (PO) and childhood trauma (CT). A total sample of 1,110 participants from the general population (68% female) was analyzed in terms of personality organization (IPO-16) and childhood trauma (CTQ) within a pairwise Markov random fields model. The network was estimated using the EBICglasso algorithm. Regularized partial correlation edge weights, node centrality indices (estimated influence, strength, bridge strength), and predictability were examined. Significant correlations were observed between PO and CT across all subdomains (p
