In this study, we utilized reliability generalization procedures to examine internal consistency estimates across 3 scales measuring the belief in a just world. The distribution of reliability estimates for the measures suggest low to moderate ranges of internal consistency reliability coefficients. The Global Belief in a Just World Scale (Lipkus, 1991) produced the highest average reliability score (alpha = .81) compared to the Just World Scale (Rubin & Peplau, 1973; alpha = .64) and the Just World Scale Revised (Rubin & Peplau, 1975; alpha = .68).
