Objective: The theory of behavioral brain systems states that the level of activity of this system is associated with a wide range of emotional disorders, including depression and anxiety. The aim of this study was to investigate the depression of MS patients based on behavioral brain systems mediated by cognitive flexibility, cognitive avoidance in the form of causal model. Method: This study was a correlational study using structural equation modeling.The statistical population includes all MS patients. They were from Mashhad and the samples were selected by available sampling method. The instruments used in this study included Beck Depression Inventory (1972), Carver & White (1994) Behavioral Brain Questionnaire, Dennis Wonderwall (2010) Cognitive Flexibility, and Sexton and Dagas (2004) Cognitive Avoidance Questionnaire. Structural modeling and Amos21 and SPSS21 software were used to analyze the data. Findings: The results showed that the activating behavioral brain system and cognitive flexibility have a negative and significant relationship with depression. Cognitive avoidance behavioral brain system has a positive and significant relationship with depression. Conclusion: The results show that the standardized indirect effect of activating behavioral system on depression is significant and the inhibitory system has cognitive avoidance on cognitive avoidance indirectly due to cognitive flexibility. Negative activator and inhibitory behavioral system can positively predict depression
