Development and preliminary validation of a Korean version of the Personal Relative Deprivation Scale

The current research developed and validated a Korean-translated version of the Personal Relative Deprivation Scale (PRDS). The PRDS measures individual differences in people’s tendencies to feel resentful about what they have compared to what other people like them have. Across 2 studies, Exploratory Factor Analyses revealed that the two reverse-worded items from the original PRDS did not load onto the primary factor for the Korean-translated PRDS. A reduced 3-item Korean PRDS, however, showed good convergent validity. Replicating previous findings using Western samples, greater tendencies to make social comparisons of abilities (but not opinions) were associated with higher PRDS (Studies 1 and 2), and participants scoring higher on the 3-item Korean PRDS were more materialistic (Studies 1 and 2), reported worse physical health (Study 1), had lower self-esteem (Study 2) and experienced higher stress (Study 2).
