Published online 15 Março 20221046-1310http://hdl.handle.net/10451/52011System justification theory contends that people are motivated to consider the social arrangements as just, legitimate and necessary. The adequate assessment of individual differences regarding this motivation is a critical issue in this field, especially in a cultural context of profound social inequalities like Brazil. We addressed this issue by proposing an adapted and modified version of the General System Justification Scale (GSJS). In Study 1, we explored the content validity of the GSJS through expert analysis. In Study 2 (n = 305), we conducted exploratory factor analysis and found a single-factor structure. In Study 3 (n = 307), we confirmed this factorial structure. In Study 4 (n = 227), we estimated the convergent-discriminating and incremental validity of the SJS by comparing it with correlated constructs. Finally, in Study 5 (n = 100), we experimentally manipulated a news story about a high (vs. low) threat to the Brazilian system, and observed the predictive validity of the GSJS. In general, the results showed that the new version of the GSJS is a valid and reliable measure. Furthermore, they suggest the new version of the GSJS is a useful tool to measure individual differences in justification of social inequalities in a context of deep social disparities.engSystem justificationMeasuresSocial inequalityStatus quoPerception of justicejournal article10.1007/s12144-022-02992-5
