The Belief in a Just World: An Examination of Reliability Estimates Across Three Measures

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 Lipkus, I. 1991. The construction and preliminary validation of a Global Belief in a Just World Scale and the exploratory analysis of the Multidimensional Belief in a Just World. Personality and Individual Differences, 12: 1171–1178. [Crossref], [Web of Science ®] , [Google Scholar]) produced the highest average reliability score (α = .81) compared to the Just World Scale (Rubin & Peplau, 1973 Rubin, Z. and Peplau, A. 1973. Belief in a just world and reactions to another's lot: A study of participants in the national draft lottery. Journal of Social Issues, 29: 73–93. [Crossref], [Web of Science ®] , [Google Scholar]; α = .64) and the Just World Scale Revised (Rubin & Peplau, 1975 Rubin, Z. and Peplau, L. A. 1975. Who believes in a just world?. Journal of Social Issues, 31: 65–89. [Crossref], [Web of Science ®] , [Google Scholar]; α = .68).
