Abstract
The purpose of present study was to compare perfectionism, negative affect and brain-behavioral systems in individualsl with and without bulimia. To achieve this, of treatment center clients, 70 bulimia nervosa patients were selected through purposeful sampling,.Furthermore,70 normal persons were selected through purposeful sampling who were matched with the control group in terms of demographic characteristics. To collect the data, the Hewitt and Flett multidimensional perfectionism scale, Hed depression and anxiety scale and Carver and White’s brain-behavioral systems questionnaires were used. Data were analyzed by multiple analysis of variance (MANOVA). Results revealed that there was significant difference between patient group and normal group in perfectionism, negative affect and brain-behavioral systems.Furthermore, Bulimia nervosa patients, in comparison with normal group, reported higher levels of perfectionism, negative affect and BAS. Also normal group showed higher level of BIS in comparison with bulimia nervosa patients.

Abstract
This study investigated the Mediating Role of Cognitive Emotion Regulation in the Relationship between Brain-Behavioral Systems and eating behaviors among individuals with overweight and obesity by structural equation modeling. The statistical population consisted of women and men suffering from overweight and obesity who went to health centers, and sports clubs of Tehran in autumn and winter of 2017. Using convenient sampling method, 500 of them were selected. Duct behavior questionnaire (Van Strien, Frijters, Bergers & Defares, 1986), Cognitive Emotion Regulation (Garnefski & Kraaij, 2006), Measurement of Inhibition / Behavioral Activation Systems (Carver & White, 1994) were used for gathering data. Findings showed that maladaptive cognitive emotion regulation relatively mediated the relationship between brain-behavioral systems, and eating behaviors. Finally ,it was determined that the model (After the modification of model based on statistical results) had a better fit to the observed data. And predictive variables significantly explained 53 percent of eating behaviors. Brain-behavioral systems and emotional cognitive regulation play an important role in predicting eating behaviors in overweight and obese patients, so their role should be considered in prevention and treatment programs.
