Results: 171 patients were included. The prevalence rate in this population was 1.68%, higher for males (2.60%) than females (0.89%), and twice as high in the Aboriginal (2.05%) than in the Torres Strait Islander (0.95%) population. High rates of alcohol and cannabis use were found. Comorbid intellectual disability was common and more frequent among Aboriginal patients.
Conclusions: The burden of psychosis in the Indigenous population of Cape York and the Torres Strait is high. Further research is needed to understand the social determinants of these disorders and to design effective social and clinical measures to alleviate this burden.
