Objective: This study aimed to analyze the potential mediating
influence of primary emotional systems and rumination on the
relationship between resilience and perceived stress.
Method: A sample of 503 undergraduate students completed a selfreport
battery including the Perceived Stress Scale (PSS), the Brief
Resilience Scale (BRS), the Ruminative Responses Scale–Brief Form
(RRS-BF), and the Affective Neuroscience Personality Scale (ANPS).
Common method bias was assessed and found not to be a significant
concern. Hypothesized relationships and indirect effects were tested
using path analysis and mediation analysis (bootstrapping), with model
fit assessed via CFI, TLI, RMSEA, and BIC indices.
Results: The final model, controlling for gender and age, demonstrated
good fit (χ²/df = 2.91, RMSEA = 0.068, TLI = 0.963, CFI = 0.998).
Resilience was negatively associated with the FEAR, SADNESS, and
ANGER systems, brooding, and perceived stress (all p<0.001). FEAR
and SADNESS were positively associated with brooding and perceived
stress. Brooding was positively associated with perceived stress. Bootstrap
analyses confirmed significant indirect effects of resilience on perceived
stress through FEAR, SADNESS, ANGER, and brooding (β= -0.253,
p = 0.011).
Conclusion: Resilience capacity may influence stress evaluation through
its relationship with primary emotional systems and rumination. These
findings suggest that interactions between subcortical emotional
mechanisms and cortical processes play a role in stress perception.
Further research should investigate negative primary emotional systems
as potential neuromodulation targets in stress processing
