Abstract: (5 Views)
The present study aimed to explain the mediating role of differentiation of self in the relationship between brain–behavioral systems and psychological resilience among adults with a history of childhood trauma. This study employed a descriptive-correlational design using structural equation modeling (SEM). The statistical population consisted of individuals with a history of childhood trauma in Tehran who attended psychological counseling and treatment centers between spring and summer 2025. We selected 218 participants using purposive sampling. The research instruments included the Childhood Trauma Questionnaire (CTQ; Bernstein et al., 2003), the Connor–Davidson Resilience Scale (CD-RISC; Connor & Davidson, 2003), the Differentiation of Self Inventory (DSI; Skowron & Friedlander, 1998), and the Behavioral Inhibition/Behavioral Activation System Scales (BIS/BAS; Carver & White, 1994). Data were analyzed using structural equation modeling. The findings indicated that the proposed model fit the data well. The results showed significant negative relationships between the Behavioral Inhibition System (BIS) and the Behavioral Activation System (BAS) and psychological resilience (p < .05). Furthermore, differentiation of self played a mediating role between psychological resilience and the Behavioral Inhibition System (BIS) and the Behavioral Activation System (BAS) (p < .05). These findings suggest that brain–behavioral systems play an important role in predicting psychological resilience among individuals with a history of childhood trauma, considering the significant role of differentiation of self.
