The purpose of this research is to test social capital as a moderating role in the relationship between organizational justice (distributive & procedural) and (personal & organizational) outcomes within the two-factor model. The two-factor model is a concept introduced by Sweeney and McFarlin (1993) who explained that distributive and procedural justices have different influences on outcomes. In the two-factor model, the effects of distributive justice on personal outcomes are more dominant compared with procedural justice. On the other side, procedural justice will be more accurate to predict the organizational outcomes compared with distributive justice. This model is based on U.S.A. setting research. Empirically, that model is not always supported in the field. The different empirical results indicate that the model is not universal cross population, but more dependent on individual differences. Based on theoretical studies, social capital is the individual differences that important in explaining human in cognition and behavior. This research is done in Indonesian setting where the researcher gathered 426 samples of full-time private university employees in Yogyakarta. In general, the result supported the hypothesis that high or low social capital will make differences in the relationship between organizational justices and personal organizational outcomes.
