This research aimed to examine the causal relationships between cognitive strategies for emotional regulation,academic passion and mindfulness among university students, and to verify the structural model that explains the direct and indirect effects between the variables. To achieve this goal,a total of (419) male and female university students at the Faculty of Education, Zagazig University (175 males, 244 females) completed scales of cognitive strategies for emotional regulation, academic passion and mindfulness.The results showed that the proposed path analysis model was consistent with the study sample data for the relationship between adaptive and maladaptive emotional regulation cognitive strategies as independent variables,academic passion(harmonic passion and obsessive passion)as mediating variables,and mindfulness as a dependent variable.There are statistically significant direct effects between adaptive emotional regulation strategies and both harmonious passion and obsessive compulsive passion,and there is a statistically significant direct effect between emotional regulation strategies and mindfulness, and there is a statistically significant direct effect between academic passion in its two dimensions and mindfulness, and there is no statistically significant direct effect between negative emotional regulation strategies and harmonious passion, while there is a statistically significant direct effect between negative emotional regulation strategies and obsessive passion, and there is a statistically significant indirect effect between positive emotional regulation strategies as an independent variable and mindfulness as a dependent variable through the variables of harmonious passion and obsessive passion together as mediating variables, while there is no statistically significant indirect effect between negative emotional regulation strategies as an independent variable and mindfulness as a dependent variable through the variables of harmonious passion and obsessive passion together as mediating variables among university students.
