A comparison of dietarian identity profiles between vegetarians and vegans

Vegetarianism and veganism are often grouped together in nutritional and psychological investigations. Yet an emerging body of literature has highlighted that vegetarians and vegans differ along a number of neurological, attitudinal, and behavioral variables. In this research, I found that vegetarians and vegans exhibit different dietarian identity profiles. Compared to vegetarians, vegans saw their dietary patterns as more intertwined with their identity (higher centrality), had more positive feelings toward their dietary in-group (higher private regard), felt as if other people judge them more negatively for following their dietary patterns (lower public regard), evaluated out-group dieters more negatively (lower out-group regard), and had stronger motivations for following their dietary patterns (higher prosocial, personal, and moral motivations). By distinguishing between vegetarians and vegans more concretely, investigators can capture meaningful within-group heterogeneity in how people think, feel, and behave when it comes to eschewing animal products.
