Ethnic diversity leads to higher levels of psychosis
Scientists sought to assess potential mechanisms underlying the observation that minority ethnic groups experience an increased risk of psychosis when living in neighborhoods of lower own-group density. The researchers found that for every ten percentage point reduction in own-group density, the relative odds of reporting psychotic experiences increased 1.07 times for the total minority ethnic sample. In general, people living in areas of lower own-group density experienced greater social adversity that was in turn associated with reporting psychotic experiences. People resident in neighborhoods of higher own-group density experience "buffering" effects from the social risk factors for psychosis.
