On the Comparison of Behavioral Activation/Inhibitory System and Temperament and Character between Addicted and Non-addicted Persons

This study was aimed to compare the behavioral activation/inhibition system and temperament and character between addicted and non-addicted people.
A descriptive research design along with a causal-comparative method was used for the conduct of this research. The research population consisted of all dependent and non-dependent men living in Kish Island, among whom 200 individuals were selected by convenience sampling method. The data were gathered using Cloninger's Temperament and Character Inventory and Behavioral Inhibition/Activation System. Data analysis was performed using Pearson correlation test and multivariate analysis of variance.
The results showed that there was no significant difference between the two groups in terms of behavioral activation system, fun seeking, and reward dependence, while there was only a significant difference between the groups in Drive and inhibition system (P Substance dependent individuals have a weaker behavioral system than non-addicted subjects. However, unlike previous studies, the drive sensitivity in non-addicted individuals was obtained higher than those addicts in this study. High levels of harm avoidance and low self-directedness affect the severity of addiction in drug dependent people. Regarding the sample large size of this study in comparison with previous studies and the homogeneity of the research sample, the conduct of similar research is needed to achieve more clear results.
