Aim: Today, eating disorders are one of the most common mental disorders that cause many problems in physical health, mental functioning, and quality of life. This research was conducted with the aim of modeling the structural equations of eating attitude based on self-differentiation, emotional reactivity and negative urgency with the mediation of emotion regulation difficulty in students of Islamic Azad University, Zanjan branch. Methods: The method of conducting the research was correlational using the SEM structural equation modeling method and the statistical population of this research included all undergraduate students in the number of 4730 people. 284 people were selected by cluster sampling method. The research tools include Garner and Garfinkel (1979) Eating Attitude Test, Drake, Murdock, Marszalek and Barber (2015) short form of differentiation inventory, Impulsive Behavior Scale (UPPS), Positive and Negative Affect Scale (PANAS) and Gratz Emotion Regulation Difficulty Scale. And Roemer (2004). To collect data, descriptive and inferential statistics and structural equations were used using SPSS26 and AMOS24 software. Bootstrap method was used in MACRO program to analyze mediating relationships. Results: The findings showed that the relationship between the structural model of eating attitude based on self-differentiation, emotional reactivity (positive and negative emotional) and negative urgency with the mediation of students' emotion regulation difficulty has a good fit (P<0.001). Differentiation relationship with negative and inverse eating attitude, relationship between emotion regulation difficulty and direct and positive eating attitude has been estimated (P<0.001). Also, positive emotional reactivity had a negative and inverse relationship with eating attitude (P<0.001). Conclusion: The findings of this study emphasize the effective role of differentiation, emotion regulation and emotional reactivity in the attitude of eating disorders in students. Therefore, the necessary training to regulate and control emotions should be done in this important segment of the society, in order to prevent the complications and consequences of disordered eating attitude, which is eating disorders.
