The aim of this study was to examine relationship between belief in just world and obesity stigmatization. The research was conducted on a large number of students at Osijek universities. Problems included determining correlation between just world beliefs, contact hypothesis and causal attributions and obesity stigmatization. Other problem was determining differences in obesity stigmatization prevalence taking into account the gender of subjects and gender of person being evaluated. Third problem was determining the contribution of just world beliefs, causal attributions and contact hypothesis to the explanation of stigmatization of obese people. The statistic analysis results did not indicate significant correlation between belief in just world and attitudes toward obese people or between types of attributions made to the cause of disorder and contact hypothesis and obesity stigmatization. Gender of the participants was shown to be negatively associated to stigmatization. The results indicate that women, more often than men, tend to have negative attitudes toward obese people. Also, trend was noticed indicating that people tend to have stricter attitude toward obese people of opposite gender, whereas they have less strict attitudes when it comes to people of the same gender. This trend, although noticed in all participants, was highly pronounced with female participants. Out of all constructs that were tested in this study, the self deceptive enhancement and gender of participants were the ones to show statistically significant predictors of stigmatization. Female participants once again showed higher tendency to negatively evaluate obese people. Socially desirable responding was shown to be a significant covariate which influenced the results. To be more precise, self deceptive enhancement, as a part of socially desirable responding, was positively correlated to the attitudes toward obese people and significant stigmatization predictor.
