A greater incidence of psychotic disorders in immigrants (in comparison to nom-immigrant population) has been established. In actuality a range of studies carried out in different socio demographic contexts and with different ethnic groups (of immigrants) identify ethnicity, neighbourhood characteristics (namely level ethnic density), discrimination and refugee status, as some of the probable factors that modulate the rate of psychotic disorder and influence its incidence in immigrants.
