such a lack of epidemiological information is due to the methods used that depend on the ethnic minority categorization schemes that are traditionally used in the UK mental health system. For example, Eastern Europeans are usually lumped into the category of “White or White British” while Middle Eastern people may fit in with either “White or White British” or “other”, therefore leading to nebulous categories that do not allow the researcher to compare different population groups by country of origin. A study by Hitch and Rack in the late 1970s was one of the few research reports published that focused on exploring Eastern and Central European immigrants diagnosed with schizophrenia in the UK. What they found was that the rates of mental illness in Polish, Russian and Bulgarian immigrants was higher than that of the British population (Hitch and Rack, 1980).
