Examining the impact of migrant status on ethnic differences in mental health service use preceding a first diagnosis of schizophrenia.

We observed fewer ethnic differences in health service use preceding the first diagnosis of psychosis when patterns are compared among first-generation migrants, rather than to the general population, suggesting that the choice of reference group influences ethnic patterning of health service use. We need a comprehensive understanding of the mechanisms behind observed differences for minority groups to adequately address disparities in access to care.
