Even though prejudice towards Bolivian immigrants is one of the main reasons for discrimination in Argentina, there is no valid measure to assess it. The aim of this study was to explore the psychometric properties of the subtle and blatant prejudice towards Bolivian immigrants scale. In addition, we tested correlations with right-wing authoritarianism, social dominance orientation, feelings towards Bolivian immigrants, and ideological self-placement. Data was collected through a convenience sample of 431 undergraduate students from Buenos Aires, with an age range from 18 to 45 years old (38.75% men and 61.25% women). Results showed adequate psychometric properties for the scale. Moreover, significant correlations between subtle and blatant prejudice and the other psychosocial variables tested were found. Implications of these findings are discussed.
