Structural relationships of dysfunctional thoughts and rumination with symptoms of eating disorder by mediating of avoidance performance

Eating disorder refers to inappropriate behaviors and attitudes that are defined as a chain of eating disorders.  Some consider anorexia as primary avoidance and bulimia as secondary avoidance. The purpose of this study was to provide a conceptual model and test it for eating behaviors based on rumination, dysfunctional thoughts, and avoidant performance. For this purpose, during a descriptive study, 312 students (198 females and 114 males) were selected through convenience sampling and evaluated in terms of symptoms of eating disorder, rumination and dysfunctional thinking and avoidance of experience.  Results of study of relationships between variable based on this structural model, showed Fits well with the data of this study and the pathways of dysfunctional thoughts and rumination with symptoms of eating disorder by mediate avoidance function are significant. Based on this structural model, rumination and dysfunctional thought as exogenous variables affect avoidance performance and avoidance performance on eating disorder as well. Based on findings of this study, it can be concluded that avoidance performance, in addition to having a direct relationship, also regulates the relationship between dysfunctional thoughts and rumination with eating disorder.
