Methods and Materials: This study employed a three-wave longitudinal panel design over a one-year period, collecting data from a sample of 482 professional and managerial women in Mexico. Validated self-report surveys were administered at three distinct time points, each separated by a 6-month interval, to capture the temporal dynamics of the psychological and interpersonal constructs. To transition beyond traditional correlational associations and establish structural directionality, the Peter-Clark (PC) causal discovery algorithm was utilized alongside robust bootstrapping techniques on the R statistical platform, supplemented by formal mediation analysis to quantify indirect pathways. Findings: The causal discovery algorithm successfully identified a robust, fully mediated indirect pathway, eliminating the direct long-term path between early hostilities and later leadership confidence. Specifically, exposure to workplace microaggressions at Time 1significantly eroded social support networks at Time 2, a directed causal edge that was retained in 92.4%of the bootstrap samples. Subsequently, this diminished social support at Time 2directly reduced leadership efficacy at Time 3, a structural path present in 88.7%of the bootstrap samples. Formal mediation analysis confirmed that social support networks act as a significant and critical mediating mechanism in this detrimental dynamic, yielding a standardized indirect effect of -0.046. Conclusion: Subtle workplace hostilities do not merely cause immediate distress, but structurally dismantle the professional social support networks fundamentally required to sustain and cultivate women’s leadership efficacy over time.</p> https://www.journals.kmanpub.com/index.php/psywoman/article/download/3719/9419
