Alternative Abstract: The purpose of the current study was to translate and validate the Reward Probability Index(RPI) developed by Carvalho and colleges(2011) with Korean adults. Exploratory Factor Analysis conducted with non-clinical 300 adults reported a two factor structure with 15 items. Confirmatory Factor Analysis with 400 non-clinical adults supported the two factor model. Results indicate a strong factor structure, internal consistency and test-retest reliability. Convergent and divergent validity were also supported. Study 2 applied the Korean RPI to examine the relationship between negative affectivity and depression. As a result, Experiential Avoidance and Reward Probability partially mediated the relationship between Negative Affectivity and Depression. These findings suggest that negative affectivity indirectly had an impact on depressive symptoms through the signifiant mediating effects of experiential avoidance and reward probability. Based on these results, implications, limitations, and suggestions for future research were discussed.
