Structural relations of brain-behavioral systems and Emotion regulation difficulties with social anxiety disorder and depression symptoms

Social anxiety disorder and depression have a high comorbidity. Understanding the mechanisms underlying the development and maintenance of these disorders is very important. Present study aims to evaluation of structural relations of brain-behavioral systems and Emotion regulation difficulties with social anxiety disorder and depression symptoms. 240 individuals (120 male and 120 female) of Tabriz University Student selected by clustering sampling and answered to following questionnaires: Carver and White's Behavioral Inhibition & Activation Scale, Difficulties in emotion regulation scale (DERS), Albany Panic and Phobia Questionnaire (APPQ) and Beck Depression Inventory. For data analysis, confirmatory factor analysis (CFA) and structural equation modeling (SEM) technique was used. Evaluation of structural model was performed using the chi-square, Root Mean Square Error of Approximation (RMSEA), Standard Root Mean Square Residual (SRMR) and comparative fit index (CFI). Results show the average fitness of the hypothesized model, the modified model that In addition to the direct relations; also had indirect relations between study variables showed a better fit. Relying on the findings of this study and emphasized the role of mediation Emotion regulation difficulties can presented a Theoretical framework to explain the complexity of the comorbidity and distinguishability between depression and social anxiety disorder.
