The aim of this graduate thesis was to examine the contribution of satisfaction of physical appearance, the locus of control, the belief in the just world, the amount of physical activity and body mass index to the explanation of the variance of prejudice towards obese people. The prejudice towards obese people was looked at from three different aspects; general unlikability, fear of gaining weight and strength of will. The correlation between the variables and the three mentioned aspects of prejudice was also checked. The study was conducted on a sample of 314 young adult women. The hypotheses have been partially confirmed. The results showed that body mass index is positively correlated with fear of gaining weight and is negatively correlated with general unlikability and power of will. Satisfaction with appearance is positively correlated with general unlikability and power of will and is negatively correlated with fear of gaining weight. Immanent justice is positively associated with general unlikability and power of will. The amount of physical activity and locus of control did not appear to be significantly correlated with any aspect of prejudice despite what was expected. Furthermore, body mass index proved to be a negative predictor and immanent justice proved to be a positive predictor in explaining the variation of general unlikability. Considering the fear of gaining weight, immanent justice and body mass index have proven to be significant positive predictors while satisfaction with appearance has proven to be a significant negative predictor. Satisfaction with appearance and immanent justice have been shown to be significant positive predictors in the explanation of the power of will.
