The Role of Brain-Behavioral Systems, Emotional Schemas and Deficits in Executive Dysfunctionin Prediction of Obsessive Beliefs in Students

The aim of this research was to investigate the role of brain-behavioral systems, emotional schemas and deficits in executive functioning in prediction of obsessive beliefs in Students. using the correlation method, 152 Undergraduate students of kharazmi University of karaj (81 girl students and 71 boy students) of the age range of 18 to 22 years were selected through available non-probability sampling and completed Carver and White Brain-Behavioral Systems questionnaire (Carver, White, 1994), Emotional Schema Scale (Leahy, 2002), Cognitive Abilities Questionnaire (Nejati, 2013) and Obsessive Beliefs questionnaire (OCCWG, 2001). in order to analysing of data, Pearson correlation coefficient and stepwise multiple regression was used.

The results also showed that there was a significant relationship (p<0/05) between Most components of emotional schemas and executive functioning with Students obsessive beliefs. Moreover, the regression results showed that predictor variables in current study could explain the 42/8 percent of the changes in obsessive beliefs variable that In the meantime, inhibitory control and selective attention component, brain-behavioral systems and demands for rationality emotional schemas, were The most important in predicting obsessive beliefs variable, respectively. based on results of this study can be said that The presence of maladaptive emotional schemas and also Reduce in effectiveness of executive functioning in people who have high levels of Brain-Behavioral Systems activity, Can predict their tendency towards obsessive beliefs.
