The role of mindfulness in predicting perceived stress through the mediation of personality traits among high school teachers in Sabzevar in the academic year ۱۴۰۳-۱۴۰۴.

The present study aimed to investigate the role of mindfulness in predicting perceived stress through the mediating role of personality traits among high school teachers in Sabzevar during the academic year 2024–2025. This research was fundamental in purpose and employed a descriptive-correlational design based on structural equation modeling (PLS). The statistical population consisted of all secondary school teachers in Sabzevar, from which 291 individuals were selected using multi-stage cluster random sampling. Data were collected using the Five Facet Mindfulness Questionnaire (FFMQ), Cohen’s Perceived Stress Scale (PSS), and the NEO Five-Factor Inventory (NEO-FFI). The collected data were analyzed using SPSS and SmartPLS software. The findings revealed a significant positive correlation between mindfulness and perceived stress (r = 0.877, p < 0.05). Moreover, mindfulness was positively correlated with personality traits (r = 0.823, p < 0.05), and personality traits were significantly related to perceived stress (r = 0.887, p < 0.05). The mediation analysis showed that personality traits play a significant mediating role in the relationship between mindfulness and perceived stress. Additionally, all sub-hypotheses were confirmed, indicating that the pairwise relationships among the study variables were statistically significant. Overall, the results suggest that mindfulness not only has a direct relationship with perceived stress but also indirectly affects it through personality traits. These findings highlight the importance of fostering mindfulness and promoting positive personality traits among teachers to reduce occupational stress and enhance psychological well-being. Based on the limitations of this study, future research is recommended to employ longitudinal and interventional designs to examine the causal relationships among these variables more accurately.
