Evidence for the Influence of Social Dominance Orientation and Intergroup Relations on the Stigma of Schizophrenia

The stigma of schizophrenia is an intergroup phenomenon associated with issues of social power. We consider that the concept of stigma power should be extended to include intergroup relations that go beyond the aspect of the relation between “schizophrenic” and “normal.” With the present study, we intend to demonstrate that perceivers hold more stigmatizing attitudes toward a person with schizophrenia belonging to the outgroup and that especially when the perceiver has a higher Social Dominance Orientation (SDO). One hundred and sixty-one participants from the general population participated in our study (50.3% male, Mage = 39.14, SD = 16.36), which was based on a 2 (Sex of Target: male vs. female) × 2 (Sex of Participant: male vs. female) × SDO between-subjects design. The participants read a standardized vignette used in previous research, depicting a person presenting the symptoms of schizophrenia, and were then asked to complete questionnaires about SDO and intention to discriminate against the depicted individual. Our analysis showed the main effect of SDO on discriminating intentions. Simple slope analysis revealed that SDO predicts male participants’ discriminating intentions when the target is a woman, while this relation is not significant when the target is a man. The exact reverse pattern was observed among female participants. Our results suggest intergroup relations and ideological motivations underpin the stigma of schizophrenia. We conclude that different group belongings of individuals with schizophrenia as well as the public’s ideological motivations should be further considered by future research and anti-stigma efforts.
