The Relationship of Behavioral Activation and Inhibition Systems (BAS/BIS), Difficulty of Emotional Regulation and Shyness with Social Anxiety Disorder in Normal Adolescents

Anxiety disorders are among the most common disorders in youth and adolescence “social anxiety” is one of the most important of these disorders. The aim of this study was to predict social anxiety disorder using three predictive factors inhibition and behavioral activation system, deficiency in emotion regulation and Shyness. The population of this descriptive – correlational study included all male and female high school students of Shahrekord. cluster sampling was used to select 1000 students (500 girls and 500 boys) from the first grade of high schools in Shahrekord. System Activation and Behavioral Inhibition Scale (BIS/BAS), Emotion Regulation Scale (RES), Social Anxiety Scale (SPIN) and Shyness Scale, were used to measure the variables. Descriptive (mean and standard variation) and inferential (correlation coefficient and regression analysis) statistical methods were used for data analysis. Findings demonstrated A significant positive correlation between social anxiety disorder and behavioral inhibition system (P<0/05), difficulties in emotional regulation (P<0/05) and shyness (P<0/05). But There was not a significant association between behavioral activation system and social anxiety disorder. (P>0/05). Stepwise multiple regression analysis indicated a predictive model for social anxiety disorder in which shyness, difficulty of emotional regulation and behavioral inhibition system were its components respectively. High sensitivity BIS system, difficulty in emotion regulating and shyness increase social anxiety.In sum, recognition of the brain-behavioral systems specialy BIS in individuals and being aware of this characteristic will decrease social anxiety disorder in them.
