Enneagram typologies can impact psychological well-being and stressful situations in college students. However, the literature is still limited on the study of the psychodynamic functioning of personality types in Spanish-speaking population, being necessary a better understanding from the network system. The objective was to analyze the network associations and centrality measures of the Enneagram personality typologies and healthy personality in Peruvian university students. A total of 261 male university students participated in this research, who responded to two instruments assessing the Enneagram personality types and a measure of healthy personality to psychosocial stress. A regularized cross-sectional network structure was estimated based on the Gaussian graph of partial correlations. The expected influence centrality, predictability and node bridging strength indices, as well as their stability and tests of differences, were also examined. It was found that Enneagram type 4 presented greater associations in the network structure with types 2 and 5. Type 6 emerged as the node with the greatest predictability. Healthy personality and type 7 acted as bridging variables between the personality domains, being causal activation links of the associative patterns of the psychodynamic styles and states according to the theorization of the Enneagram system. The accuracy of the network was adequate and its strength stability was adequate (CS = .52). It can be concluded that suggesting type 6, 7 with healthy personality to psychosocial stress, play an important role in the development of causal activation of the network model, where type 6 is more influential in direct and indirect relationships in the network. Consequently, it is relevant for future research to consider the typological knowledge of the Enneagram for implementation in university programs and to evaluate the psychological correlates of greater impact on mental health.
