PURPOSE: The present study sought to examine the diagnosis and treatment of mental disorders comparing Asian American (AA) and non-Hispanic Whites (WNH) drawn from a population accessing a large general hospital for any reason. Socio-demographic predictors of diagnosis and treatment were also explored.

METHODS: Data were obtained from de-identified medical records in the Partner Health Care System's Research Patient Data Registry.

RESULTS: The final sample included 345,070 self-identified WNH and 16,418 self-identified AA's between January 1, 2009 and December 31, 2009. WNH patients were more likely than AA patients to carry a diagnosis of a mental disorder (18.1% vs. 8.6%, p < 0.0001) and were more likely to receive psychotropic medication treatment (15.0% vs 8.5%, p < 0.0001). Logistic regression analyses of the AA cohort identified several risk factors (i.e. language, religion, gender, age) predicting the diagnosis of a mental disorder or use of psychotropic medication.

CONCLUSIONS: Our findings on the racial disparity in mental disorder diagnosis and treatment between AA and WNH patients suggest that mental disorders are under-recognized and mental health services are under-utilized in the AA community. There remains a need for health care providers to improve screening services and to gain a better understanding of the cultural barriers that hinder mental health care among AA patients.
