The present study investigated the potential mediating effects of the Big Five personality traits between emotion regulation strategies (cognitive reappraisal and expressive suppression) and conflict management styles. Statistical analyses were conducted on a sample of emerging adults (N = 373; 18–23 years) using the Jamovi software package. Multiple linear regression and mediation analyses showed that cognitive reappraisal and expression suppression did not significantly pre-dict conflict management styles (p>.05). Moreover, the indirect effects of big five personality traits were not statistically significant, all bootstrap confidence intervals crossed zero. Thus, the null hypotheses were accepted. Nevertheless, it is axiomatic that defining the boundary conditions of socio-emotional competencies is crucial to advance this field of study. The non-significant findings suggested that internal self-regulation processes and external conflict tactics may operate through separate psychological pathways during emerging adulthood, a developmental period marked by systemic changes and continued neurological development. Essentially, these findings clarified the distinct empirical landscape of this demographic that suggested important clinical utility, not a conceptual failure. In conclusion, the present study contributed important parameters to the ex-isting body of knowledge, showing that tactical conflict modes in youth may be determined by immediate situational variables and may not be structurally mediated by stable dispositional traits.
