Abstract
AimThe increased rate of psychosis and poorer service-related outcomes in UK African-Caribbeans may in part be related to racism; racism as an aetiological factor remains comparatively under-investigated. We wanted to develop a measure of perceived racism in UK African-Caribbean patients with psychosisMethodsWe modified the Perceived Racism Scale (PRS) by substituting a mental-health-services' racism domain for the employment-racism domain and administered it to a sample of 150 individuals.Results110 people completed the PRS with a total mean perceived racism score of 54.2 for the previous year and 71.3 for the lifetime. The modified instrument had good internal consistency, and both a similar factor-analytic structure and sampling adequacy to the original instrument.Clinical ImplicationsThe modified PRS was acceptable to the sample, withstands statistical scrutiny and produced similar totals to those in previously-tested populations. Subjective measurement of perceived racism may improve understanding of psychosis in African-Caribbeans, improve engagement and, hopefully, outcome.
Highlights
People of African-Caribbean origin with psychosis in the UK are reported to have different service-related outcomes and increased rates of psychosis relative to their white counterparts [1,2,3]
Earlier UK work reported raised incidences of schizophrenia in all minority ethnic groups presenting to psychiatric services within a deprived, inner-city setting [9]
The statistical evaluation of the new domain showed it to be equivalent to the unmodified Perceived Racism Scale (PRS)
Summary
People of African-Caribbean origin with psychosis in the UK are reported to have different service-related outcomes and increased rates of psychosis relative to their white counterparts [1,2,3]. A literature-review indicates that both the excess risk of psychosis as well as the altered servicerelated outcome in UK African-Caribbeans with psychosis may at least in part be explained by racism [4]. A Netherlands group found a doseresponse relationship between discrimination and incidence rate ratios of psychosis in ethnic minority groups [7]. Their second study failed to find perceived discrimination to be a risk factor for schizophrenia [8]. Earlier UK work reported raised incidences of schizophrenia in all minority ethnic groups presenting to psychiatric services within a deprived, inner-city setting [9]
