Young migrants to Australia identified as being at ultra-high risk for psychosis: Pathways to care and clinical characteristics.

INTRODUCTION

Despite the established finding that migrants are at higher risk of developing a first-episode psychosis, they are under-represented in cohorts of young people identified as being at ultra-high risk for psychosis (UHR). Therefore, in order to determine the reasons for these conflicting findings, this study examined the pathways to care and clinical presentation of migrants attending an At-Risk Mental State clinic.

METHODOLOGY

This study included consecutive UHR cases identified over five years attending the PACE clinic in Melbourne, Australia. The CAARMS was used to assess the severity of attenuated psychotic symptoms. Depressive symptoms and functioning were measured using the PHQ9 and GAF, respectively.

RESULTS

Over the five-year study period, 461 UHR young people attended the PACE clinic and 13.7% were first-generation migrants. A higher proportion of migrants were referred by community health services, such as general practitioners, than other referral sources. Australian born UHR patients were more likely to be referred via another mental health service. There was no difference in the type or severity of attenuated psychotic symptoms based on migrant status, except that there was a trend for young African migrants to have more severe unusual thought content. Depressive symptoms and poor functioning were highly prevalent across the total cohort and did not differ according to migrant status.

CONCLUSIONS

It is not yet understood why migrants are under-represented in UHR cohorts. Qualitative interviews of migrants, who are not typically identified in the UHR stage, could provide insights into the barriers to accessing care.
