Aim: This study was performed aimed to evaluate the psychometric properties of Behavioral activation and Behavioral inhibition systems scale in nonclinical groups. Method: The study population were from Urmia and Kharazmi University, among which 368 and 472 respectively selected as the final sample. For determine the psychometric properties of Behavioral activation and Behavioral inhibition systems scale, exploratory and confirmatory factor analysis was used. Then reliability of this scale were measured through the Cronbach's alpha coefficient, retest, and splitting, as well as criterion validity its was examined with positive and negative affect scale sensitivity to punishment and reward Scale. Results: The results of the exploratory factor analysis, four factors were obtained. Also fit indictors in confirmatory factor analysis was supported from four-factor model. Alpha coefficients, retest and splitting Showed satisfactory internal consistency, and patterns of correlation coefficients between subscales Persian version of Behavioral activation and Behavioral inhibition systems with positive and negative affect scale and sensitivity to punishment and reward Scale showed good criterion validity for this scale. Conclusion: The findings of the present study was similar to original culture, therefore the Persian version of Behavioral activation and Behavioral inhibition systems scale is a good tool for assessment characteristics consistent with BAS and BIS system and their subscales.
