Increased rates of social defeat and schizotypy in racial minorities

Abstract

This study examines the extent to which a measure of multidimensional schizotypy is associated with experiences of social defeat. Based on the social defeat hypothesis of psychosis, which suggests that chronic stressful experiences leading to social defeat increase risk for psychotic-like experiences, we expect that individual differences on a schizotypy measure would be explained by differences in social defeat. We hypothesized that racial and ethnic minorities would report higher rates of schizotypy relative to non-minorities and that social defeat would explain those differences. Participants included a community sample of English-speaking adults ages 18 and older, recruited from online social media platforms (N = 501; M age = 28.06). Demographic information was collected, as well as the Multidimensional Schizotypy Scale–Brief (Kwapil et al., 2018) and the Defeat Scale (Gilbert & Allan, 1998). Analyses revealed that social defeat and schizotypy scores are highly correlated. Examination of group differences revealed that racial and ethnic minorities reported higher rates of schizotypy and higher rates of social defeat than non-minorities. ANCOVA analyses revealed that, after controlling for social defeat scores, racial and ethnic status was no longer significantly associated with schizotypy scores.
