Abstract :
Introduction: According to Gray’s Reinforcement Sensitivity Theory (RST), individual differences in the
sensitivity of basic brain systems are thought to underlie the personality dimensions and to have relevance
for psychopathology. The present study aims at studying the relationship between BIS/BAS and
psychological symptoms.
Methods: In this regard, 361 students (205 boys-156 girls) in Tabriz University were selected by cluster
sampling method and then tested by symptom check list -90-R (SCL-90-R) and inventory of behaviour
inhibition/activation systems. The data were analyzed via Pearson Correlation coefficient and hierarchical
regression.
Results: The results show that behavioural inhibition system has a significant relationship (p<0.05) with all
the 9 symptoms. Also, regression results show that 1% of sensitivity and frequency of symptoms were
explained by Behavioural inhibition system (BIS).
Conclusion: It seems that the behavioural inhibition/activation systems (BIS/BAS) are one of the important
components in explaining psychological symptoms, especially in the youth.
