All other neighborhoods were defined as "low ethnic density." Compared with native Dutch, the incidence of psychotic disorders for first and second generation immigrants from Morocco, Surinam, and Turkey living in The Hague was significantly increased in low ethnic density neighborhoods. Immigrant populations in these neighborhoods had psychotic disorders more than two times the rate of immigrants living in high ethnic density neighborhoods. While the findings were consistent for all three ethnic groups, Moroccans had the highest incidence of schizophrenia in both high and low density neighborhoods.

"Increasingly, investigators suspected that the social experiences of immigrant groups after migration contribute to their elevated risk. However, until this body of research -- large enough to examine the incidence of psychotic disorders for immigrant groups within a single urban area -- few studies had the data to confirm that increased incidence of psychotic disorders among immigrants depended strongly on neighborhood context," noted Dr. Susser.

Neighborhood ethnic density was assessed and investigated at the time of first treatment contact. In future studies, the researchers suggest it might be feasible to collect data on neighborhood context in childhood and adolescence. This approach could be used to determine the developmental period during which neighborhood ethnic density is most important.
