Assessing Personal and General Belief in a Just World: Adaptation of a Scale to the Brazilian Context/Medindo crenca no mundo justo pessoal e geral: adaptacao de uma escala ao contexto brasileiro/Midiendo creencia en el mundo justo personal y general: adaptación de una escala al contexto brasileño

This article aims to adapt the Belief in a Just World Scale to the Brazilian context, providing evidence of its reliability and factorial validity. Two studies were carried out in virtual environments. Study 1 aimed at knowledge of the measure's factorial structure and its reliability. Its participants were 300 individuals with a mean age of 26.4 years (61.3% females), who satisfied the scale and demographic requirements. The results indicated a 2-component structure: personal belief in a just world [7 items, eigenvalue = 4.42, and Cronbach's alpha ([alpha]) of .83], and general belief in a just world (6 items, eigenvalue = 1.67, and [alpha] = .69). Study 2 aimed to confirm the previous 2-factor structure. Its participants were 331 individuals with a mean age of 27.1 years (64.4%% females). The fit indices supported the 2-factor model [GFI = .92, CFI = .91, and RMSEA = .07 (CI90% = .05-.08)], which showed acceptable reliability coefficients ([alpha] = .82 and .71, respectively). In conclusion, the findings support evidence for the factorial validity and reliability of this measure, which can be used in future studies in Brazil.
