Ethnic inequalities in severe mental disorders: where is the harm?

Engagement with services in Black African and Caribbean people with psychosis: The role of social networks, illness perceptions, internalized stigma, and perceived discrimination

OBJECTIVES

Research and policies in the United Kingdom have repeatedly highlighted the need to reduce ethnic disparities and improve engagement with mental health services among Black African and Caribbean people with psychosis. The aim of this study was to examine the role of social network characteristics and psychological factors in engagement with services in Black people with psychosis.

METHODS

A cross-sectional study was conducted with 51 Black African and Caribbean adults with non-affective psychosis and currently receiving care from mental health services in England. Measures were completed to examine relationships between social networks, illness perceptions, perceived racial or ethnic discrimination in services, internalized stigma, and current engagement with services from service user and staff perspectives.

RESULTS

Social network composition (ethnic homogeneity) moderately correlated with better service user and staff reported engagement. Greater perceived personal control over problems was associated with better staff reported engagement. Lower perceived ethnic or racial discrimination in services, and specific illness perceptions (higher perceived treatment control, greater self-identification with psychosis symptoms, more concern and greater emotional response related to problems) were associated with better service user reported engagement. Internalized stigma was not associated with service engagement. Multivariate regression analyses suggested that a more ethnically homogenous social network was the strongest predictor of better service user and staff reported engagement.

CONCLUSIONS

Psychosocial interventions that target social networks, perceived ethnic and racial discrimination in services, and illness perceptions may facilitate better engagement and improve outcomes. Further longitudinal studies are required to examine causal mechanisms.

To cross or not to cross: Clinical boundary considerations with persons who are refugees

Recent studies suggest that culturally divergent explanatory models of illness and treatment practices, differing physician-patient goals and expectations, and mistrust and misunderstandings between refugee patients and health care professionals are associated with lower health care utilization and outcomes among refugees in Western host countries. In our experience working as psychiatrists with persons who are refugees, we have found that attention to the processes that define and redefine boundary relationships has important implications for therapeutic care, as well as for training residents and others in culturally-responsive care. This article examines the manner and micro-processes by which boundaries are established, maintained, or altered between medical provider and person who is a refugee as a key pathway in the development of working relationships that are culturally sensitive. We work from an expanded concept of boundaries in psychiatry, viewing boundaries as a way of describing interactions that play important and even critical roles in advancing, impeding, and redefining significant aspects of the therapeutic relationship between practitioner and patient. The quality of the interactions occurring minute by minute within treatment sessions provides the foundation from which relationships are defined, parameters of openness or closure of communication are conveyed, and the power structure is laid out. We offer Martin Buber's formulation of the I-Thou relationship as the philosophical grounding of flexible, culturally sensitive boundary behaviors. At its best, boundaries of mutual engagement that are respectful and cognizant of a patient's individuality and cultural history and values are conveyed to the refugee patient.

Ethnic inequalities in the incidence of diagnosis of severe mental illness in England: a systematic review and new meta-analyses for non-affective and affective psychoses

PURPOSE

Although excess risks particularly for a diagnosis of schizophrenia have been identified for ethnic minority people in England and other contexts, we sought to identify and synthesise up-to-date evidence (2018) for affective in addition to non-affective psychoses by specific ethnic groups in England.

METHODS

Systematic review and meta-analysis of ethnic differences in diagnosed incidence of psychoses in England, searching nine databases for reviews (citing relevant studies up to 2009) and an updated search in three databases for studies between 2010 and 2018. Studies from both searches were combined in meta-analyses allowing coverage of more specific ethnic groups than previously.

RESULTS

We included 28 primary studies. Relative to the majority population, significantly higher risks of diagnosed schizophrenia were found in Black African (Relative risk, RR 5.72, 95% CI 3.87-8.46, n = 9); Black Caribbean (RR 5.20, 95% CI 4.33-6.24, n = 21); South Asian (RR 2.27, 95% CI 1.63-3.16, n = 14); White Other (RR 2.24, 95% CI 1.59-3.14, n = 9); and Mixed Ethnicity people (RR 2.24, 95% CI 1.32-3.80, n = 4). Significantly higher risks for diagnosed affective psychoses were also revealed: Black African (RR 4.07, 95% CI 2.27-7.28, n = 5); Black Caribbean (RR 2.91, 95% CI 1.78-4.74, n = 16); South Asian (RR 1.71, 95% CI 1.07-2.72, n = 8); White Other (RR 1.55, 95% CI 1.32-1.83, n = 5); Mixed Ethnicity (RR 6.16, 95% CI 3.99-9.52, n = 4).

CONCLUSIONS

The risk for a diagnosis of non-affective and affective psychoses is particularly elevated for Black ethnic groups, but is higher for all ethnic minority groups including those previously not assessed through meta-analyses (White Other, Mixed Ethnicity). This calls for further research on broader disadvantages affecting ethnic minority people.

Subclinical psychosis in adult migrants and ethnic minorities: systematic review and meta-analysis

BACKGROUND

It is well established that migration and ethnic minority status are risk factors for psychotic disorders. Recent studies have aimed to determine if they are also associated with subclinical psychosis (psychotic-like experiences and schizotypal traits).

AIMS

We aimed to determine to what extent migrant and ethnic minority groups are associated with higher risk of subclinical psychosis.

METHOD

We conducted a systematic review, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, and examined findings by ethnicity, migrant status, outcomes of subclinical psychosis and host country. A meta-analysis was carried out with robust variance estimation where possible, to handle statistically dependent effect size estimates.

RESULTS

We included 28 studies (19 studies on psychotic-like experiences and 9 studies on schizotypal traits) and found that ethnicity, but not migrant status, was associated with current and lifetime psychotic-like experiences. In the narrative analysis, we observed the effect of psychosocial risk factors on this association: Black ethnicity groups showed consistent increased prevalence of current and lifetime psychotic-like experiences compared with the reference population across countries.

CONCLUSIONS

More generalisable and standardised cohort studies of psychotic-like experiences and schizotypal traits in relation to migration/ethnicity are necessary to examine the effects of exposures and outcomes in different contexts, and to understand the underlying mechanisms of the association between subclinical psychosis and migrant and ethnic minority status.
