ABSTRACT There is considerable evidence that incidence of schizophrenia and other psychoses varies across ethnic groups in the UK, with particularly high rates for people of African-Caribbean origin.
The aims of this shady were to estimate in a community-based sample of people from ethnic minorities: 1) the prevalence of psychotic symptoms; and 2) risk factors for reporting psychotic symptoms.
Face-to-face interviews were carried out with a probabilistic sample of 4281 adults from six ethnic groups living in the UK. Psychotic symptoms were measured using the psychosis screening questionnaire (PSQ).
There was a twofold higher rate of reporting psychotic symptoms on the PSQ in Black Caribbean people compared with Whites. Adjustment for demographic factors had little effect on this association.
Prevalence rates of psychotic symptoms were higher in people from ethnic minorities, but were not consistent with the much higher first contact rates for psychotic disorder reported previously, particularly in Black Caribbeans.

    • "The link between socio-economic status and mental health has long been established, with mental health problems more prevalent in communities with greatest deprivation (Weich & Lewis, 1998). Ethnic minorities tend to have higher rates of poverty than the White British population (Kenway & Palmer, 2007), while there is evidence that some subgroups display increased incidence of psychosis (Bhugra, Leff, Mallett, Der, Corridan & Rudge, 1997; King et al., 2005) and common mental disorders such as anxiety and depression (Weich et al., 2004). In some cases mental health problems interact with lower income to the greatest detriment of African Caribbean, Pakistani and Bangladeshi populations (Mangalore & Knapp, 2012). "

    • "Motivated by previous studies that indicate significantly more frequent endorsement of psychotic-like symptom by Blacks, including African-Americans and Caribbean Blacks (Arnold et al. 2004; Ferron, Barron, and Chen 2002; King et al. 2005), this study demonstrates the importance of examining heterogeneity within the Black American population and across other racial/ethnic minority populations in the USA. Furthermore, our results suggest that psychotic like symptoms could be indicative of underlying distress, depression, and even coping with discrimination and other stressful circumstances, which if better understood and better assessed could assist in providing culturally responsive care.

    ABSTRACT: Objective. To examine racial-ethnic differences in the endorsement and attribution of psychotic-like symptoms in a nationally representative sample of African-Americans, Asians, Caribbean Blacks, and Latinos living in the USA.Design. Data were drawn from a total of 979 respondents who endorsed psychotic-like symptoms as part of the National Latino and Asian American Study (NLAAS) and the National Survey of American Life (NSAL). We use a mixed qualitative and quantitative analytical approach to examine sociodemographic and ethnic variations in the prevalence and attributions of hallucinations and other psychotic-like symptoms in the NLAAS and NSAL. The lifetime presence of psychotic-like symptoms was assessed using the World Health Organization Composite International Diagnostic Interview (WMH-CIDI) psychotic symptom screener. We used logistic regression models to examine the probability of endorsing the four most frequently occurring thematic categories for psychotic-like experiences by race/ethnicity (n > 100). We used qualitative methods to explore common themes from participant responses to open ended questions on their attributions for psychotic-like symptoms.Results. African-Americans were significantly less likely to endorse visual hallucinations compared to Caribbean Blacks (73.7% and 89.3%, p p p p supernatural, ghosts/unidentified beings, death and dying, spirituality or religiosity, premonitions, familial and other. Respondents differed by race/ethnicity in the attributions given to psychotic like symptoms.Conclusion. Findings suggest that variations exist by race/ethnicity in both psychotic-like symptom endorsement and in self-reported attributions/understandings for these symptoms on a psychosis screening instrument. Ethnic/racial differences could result from culturally sanctioned beliefs and idioms of distress that deserve more attention in conducting culturally informed and responsive screening, assessment and treatment.

    • "Fearon et al., 2006, see also Bhui et al., 2003 for review), with the highest rates in younger British-born Afro-Caribbeans (Sugarman & Crawford, 1994) – a finding that has persisted at least to the second generation (Pinto, Ashworth, & Jones, 2008). This finding seems to extend to measures of schizotypal characteristics that are seen in non-clinical populations as well: greater proneness to psychosis in the form of delusional ideation, hallucinatory experiences, and presence of psychotic symptoms in the Afro-Caribbean healthy population have been found ( Johns, Nazroo, Bebbington, & Kuipers, 2002; King et al., 2005; Morgan et al., 2009; Sharpley & Peters, 1999). It is important to emphasize that these findings do not reflect greater psychopathology, but instead, greater tendencies to some types of experience, and their attribution. "

    ABSTRACT: Previous research has highlighted increased risk for schizophrenia in Afro-Caribbeans as well as over-representation in the prison population. This small-scale study examined the relationship between criminality, ethnicity, and psychosis-proneness in a male prison sample. Twenty British Caucasian and 20 Afro-Caribbean prisoners were divided into equal sub-groups of violent and non-violent offenders. Participants completed measures of schizotypy, delusional ideation, and hostility. Afro-Caribbean offenders scored more highly on negative schizotypy and delusional ideation than their Caucasian counterparts. Violent offenders scored more highly on the positive symptoms of schizotypy than non-violent prisoners. Both ethnicity and violent offending may be relevant factors when considering vulnerability to psychosis in the offending population.
