Does ethnicity affect need for mental health service among New Zealand prisoners?

Objective: The National Study on Psychiatric Morbidity in New Zealand Prisons identified undiagnosed mental illness and unmet treatment needs for mentally disordered offenders. As approximately 50% of prisoners are of Maori and 8.3% Pacific Island ethnicity, we analyzed the data to determine if there were any differences in the rates of major mental disorders between ethnic groups.
