Personal relative deprivation (PRD) is the belief that one is worse off than other people who are like oneself, in a way that seems unfair and which induces resentment. Previous work suggests that PRD may be associated with increased preference for energy dense/unhealthy foods, and more broadly that PRD entails an increased focus on gaining rewards even if these may come with longer-term costs. We report two studies that build on this research by examining the correlation between PRD and self-reported reward-based eating drives (RED). In both studies, higher PRD was associated with greater RED, whereas other indicators of objective and subjective status had little or no meaningful association with RED. RED was also positively associated with negative affect (examined in Study 1) and low self esteem (examined in Study 2), and negatively associated with age. In multiple regression analyses in which all predictors were entered simultaneously, negative affect, self esteem and age continued to predicted RED over and above the effects of other variables, but there was less indication that PRD provided unique predictive power; in Study 1, there was a modest positive effect of PRD but the 95\% CIs were quite wide and included zero; in Study 2, which used a larger sample and produced a more precise parameter estimate, there was a positive effect of PRD with 95\% CIs that just included zero when conventional OLS regression was used, and which just excluded zero when robust regression was used. Taken together, the data suggest an association between relative deprivation and reward-based eating which could form the basis for productive future inquiry.
