Doubling-down on deprivation: Using latent profile analysis to evaluate an age-old assumption in relative deprivation theory.

Theorists have long argued that two forms of relative deprivation exist: individual-based relative deprivation (IRD) whereby a person feels deprived relative to other individuals and group-based relative deprivation (GRD) whereby a person feels his/her ingroup is deprived relative to other groups. Combinations of IRD and GRD are therefore assumed to produce four response profiles: (i) high on IRD and GRD (i.e. 'doubly deprived'); (ii) high on IRD, low on GRD; (iii) low on IRD, high on GRD; or (iv) low on IRD and GRD. The existence of these profiles, however, has never been assessed. We address this oversight by using latent profile analysis to identify distinct response patterns to measures of IRD and GRD. Across two studies, we found no support for this typology, nor the oft-assumed doubly deprived profile. Rather, response patterns showed moderate levels of IRD across discrete profiles accompanied by considerable variability in GRD. [ABSTRACT FROM AUTHOR]
