Prevalence of psychosis in black ethnic minorities in Britain: analysis based on three national surveys

The role of Black-led community organisations in supporting Black mental health: a Black emancipatory action research project

OBJECTIVE

To explore the role of Black-led community organisations in supporting Black mental health and wellbeing in the UK.

DESIGN

A qualitative, Black Emancipatory Action Research Framework was adopted. Framework application involved adequately compensating community organisations for their consultancy role; having 'research conversations' rather than interviewing participants; and focusing outputs on community benefit. Eight individual and group research conversations took place with nine Black directors, employees and volunteers working with Black-led community organisations, aged between 19 and 62, living in the UK. Reflexive thematic analysis was used to analyse conversations.

RESULTS

Three themes were developed in relation to what Black-led community organisations do for Black mental health. These are: identify and respond to mental health needs; selectively build relationships with mainstream services; and drive social and systemic improvements. Findings revealed that Black-led community organisations uniquely identify and address mental wellbeing by offering respite from racism, hosting activities, and meeting urgent needs. They navigate and facilitate access to health and social systems, protect communities from harmful services, and advocate for social and systemic change. Drawing on the study design, findings, and the broader literature, we propose three key changes to current funding, community, and research practices. These are a reconsideration of how Black-led organisations' work is valued and measured, a forging of greater collaboration between these organisations, and bolder consideration of how research practice can benefit Black communities.

CONCLUSIONS

Black-led organisations play multiple roles in supporting individual and collective mental health, crucial for mediating the effects of racism and mitigating ethnic inequalities. To our knowledge, this is the first study to both illuminate the critical role of community organisations in promoting Black mental health in the UK and to prioritise participant, and community, benefit throughout the research process.

Mental health beliefs and help-seeking in an African descended sample with experiences of psychosis

BACKGROUND

African-descended groups with psychosis have poorer clinical outcomes and more negative pathways to care than White-British groups. It is therefore important to investigate potential contributing factors to this disparity.

AIMS

To explore the relationships between beliefs about schizophrenia and attitudes towards accessing help from mental health services in an African-descended UK-based sample with psychosis.

METHOD

Thirty-four participants with self-reported experiences of psychosis completed the Illness Perception Questionnaire for Schizophrenia and the Inventory of Attitudes towards Seeking Help from Services.

RESULTS

Beliefs about coherence of symptoms and treatment control were the only significant individual predictors of attitudes towards accessing help from mental health services subscales.

CONCLUSIONS

Implications of the findings include the use of culturally-appropriate educational resources and the generation of culturally-informed, collaborative psychological formulations to help guide to guide treatment choice.

Exploring the Characteristics of Men Aged 55+ Who Use Mental Health Community Care and Support Services: A Secondary Analysis of the Adult Psychiatric Morbidity Study in England

ObjectivesThe aim of this study is to understand the demographic and situational characteristics of men over 55 who have used a community support service. Method: Hierarchical multivariable logistic regression was conducted using anonymised data from the Adult Psychiatric Morbidity Study 2014. Results: Need factors such as having a common mental disorder (CMD), poor general health and having counselling/therapy were the most relevant to use of a community support service. It was more common for older men (85+), single men, and those who reported experiencing several traumatic life events to have used a community support service. Discussion: The results are critically discussed by considering the roles of gender, ageing, and social support, which might influence the use of community support services. There is a need for more awareness of categories such as age and previous service use, and how they might influence community support help seeking.

Associations between ethnicity and mental health problems among children and adolescents in the United Kingdom: A systematic review and narrative synthesis

BACKGROUND

The associations between ethnicity and mental health problems (MHPs) among children and adolescents in the UK have been reported in recent years. However, this is the first review to compare and synthesise these associations and provides a deep understanding of child MHPs across ethnic groups in the UK.

METHOD

A comprehensive literature search across seven electronic databases and fifteen websites was conducted. The inclusion criteria focused on studies reporting quantitative associations between ethnicity and MHPs for children and adolescents aged 0-19 residing in the UK. Given the high heterogeneity of the studies, a narrative synthesis was adopted to analyse the associations.

RESULTS

Twelve studies met the inclusion criteria, involving a total of 48,281 participants. The review reports no significant differences in the risk of experiencing general MHPs among children from Indian, Pakistani, Bangladeshi, and Black Caribbean groups compared to their White British counterparts. However, Black African children were less likely to develop general MHPs, while children in the Pakistani, Bangladeshi, and Black Caribbean groups showed a higher risk for internalising problems. Externalising and conduct problems were similarly likely among children from Pakistani and Bangladeshi backgrounds compared to White children, with Black Caribbean children showing a higher likelihood of these issues.

CONCLUSION

The findings suggest that most ethnic minority children and adolescents in the UK have comparable risks of MHPs to their White counterparts, although specific risks vary by ethnicity and MHP types. The results underscore the need for multifaceted analyses considering socioeconomic and cultural factors, beyond simple ethnic categorisations, to inform mental health services that effectively meet the diverse needs of the UK's child population. This review calls for more detailed and uniform categorisation in future research to understand and address the mental health disparities across different ethnic groups.

The revised Psychosis Attachment Measure: further psychometric evidence

PURPOSE

Disorganised attachment is a key concept in understanding the development of psychosis. However, existing questionnaires of adult attachment do not adequately measure this construct hindering future research into the psychosocial causes of psychosis. The most widely measure of adult attachment in people experiencing psychosis is the Psychosis Attachment Measure (PAM). The measure has recently been revised to include disorganised attachment items. This study develops previous research by providing a rigorous examination the psychometric properties of the revised questionnaire (PAM-R).

METHODS

A total of 407 participants with self-reported experiences of psychosis completed a battery of questionnaires which included the PAM-R and other measures which were conceptually related to the concept of disorganised attachment.

RESULTS

Confirmatory factor analysis (CFA) indicated a three-factor solution with factors corresponding to anxious, avoidant, and disorganised attachment. The majority of the fit statistics were acceptable with the exception of the RMSEA statistic. Internal consistency and test-retest reliability were good for all subscales. The disorganised subscale correlated in expected directions with other measures of attachment, dissociation, trauma, and psychotic experiences.

CONCLUSION

The PAM-R is a valid and reliable measure of adult attachment. It is a practical assessment tool for clinicians and researchers to measure insecure and disorganised attachment patterns that is acceptable to people experiencing psychosis.

Exploring black women's experiences of mental health services: a literature review

The prevalence of mental health issues among black women is high, but they are underrepresented among mental health service users. This article details a systematised review of the literature that explored black women's perceptions and experiences of, and barriers to, engaging with mental health services. A total of 16 articles from the UK and North America were included in the review. Four main themes were identified as presenting barriers to black women's engagement with services: mistrust; sociocultural factors; lack of awareness; and practical barriers. The intersection of gender and race was evident in the 'strong black woman' ideal, which may have hindered their recognition and disclosure of mental health conditions, as well as in practical barriers such as costs and caring responsibilities. Historical and cultural perceptions of mental health issues and healthcare services, alongside their previous negative experiences of services, may prevent many black women from accessing essential support. Nurses and other healthcare professionals have an important role in engendering trust, challenging racism and promoting positive mental health.

Psychosis prevalence in London neighbourhoods; A case study in spatial confounding

Analysis of impacts of neighbourhood risk factors on mental health outcomes frequently adopts a disease mapping approach, with unknown neighbourhood influences summarised by random effects. However, such effects may show confounding with observed predictors, especially when such predictors have a clear spatial pattern. Here, the standard disease mapping model is compared to methods which account and adjust for spatial confounding in an analysis of psychosis prevalence in London neighbourhoods. Established area risk factors such as area deprivation, non-white ethnicity, greenspace access and social fragmentation are considered as influences on psychosis. The results show evidence of spatial confounding in the standard disease mapping model. Impacts expected on substantive grounds and available evidence are either nullified or reversed in direction. It is argued that the potential for spatial confounding to affect inferences about geographic disease patterns and risk factors should be routinely considered in ecological studies of health based on disease mapping.

The structure of the Prodromal Questionnaire-16 (PQ-16) in a non-help-seeking youth population: Exploratory and confirmatory factor analyses study

AIMS

The present study aimed to examine the structure of the Prodromal Questionnaire-16 (PQ-16) in a non-help-seeking youth population through exploratory and confirmatory factor analysis. Previous studies have not examined the structure of this self-report measure in this age group outside a clinical setting.

METHODS

Participants (n = 1165) aged 11-19 years were recruited to an epidemiological study of young people in Northern Ireland, and completed the PQ-16 alongside other measures. The dataset was split randomly in two for separate factor analyses. A polychoric correlation matrix was created and exploratory factor analysis was used to identify the optimal number of factors. In addition, based on previous studies, six models were tested through confirmatory factor analysis to determine best fit. A one-factor, 3 two-factor, a three-factor and a four-factor model were all tested.

RESULTS

The exploratory factor analysis indicated a two-factor structure of the PQ-16 in this population, which we have labelled 'general unusual experiences' and 'hallucinations'. Confirmatory analysis indicated that the two-factor model identified through the exploratory analysis was the best fit for the data.

DISCUSSION

The present study suggests that the structure of the PQ-16 may vary across age groups in non-clinical settings, and adds further support to the validity of the PQ-16 is a cost-effective, easy to administer self-report measure that is suitable for use in non-help-seeking populations as a screening tool for prodromal symptoms.

The ethnic density effect as a contextual influence in ecological disease models: Establishing its quantitative expression

Research suggests higher neighbourhood ethnic minority density to be associated with lessened chances of ethnic group illness. We focus on the density effect on psychosis, arguing that (at higher ethnic concentrations) it acts as a contextual influence attenuating the compositional influence whereby minority ethnicity is associated with higher psychosis risk. In terms of ecological disease regression, the ethnic density effect will then be apparent in nonlinear impacts of minority concentration. Contextual effects may also be evident in spatially varying regression coefficient models for psychosis. Nonlinearity or heterogeneity may be associated with other contextual processes where geography modifies demography (e.g. deprivation amplification). We illustrate these issues with an analysis of psychosis prevalence in 4835 London neighbourhoods. The data are collected in primary care (during 2019/20) using clinical diagnosis (e.g. based on referrals to specialists or psychosis hospitalisation), and refer to patients currently under care: such care may extend retrospectively over several years. The data offer a complete population perspective in contrast to survey data, which typically offer limited geographic perspectives. We consider impacts on psychosis prevalence of non-white ethnicity, as well as those of deprivation, social fragmentation and urbanicity. We find evidence suggesting nonlinear impacts of non-white ethnicity on psychosis (essentially flat risk above a threshold concentration), but find no evidence for deprivation amplification.

Multifaceted risk for non-suicidal self-injury only versus suicide attempt in a population-based cohort of adults

BACKGROUND

Non-suicidal self-injury and suicide attempt represent significant public health concerns. While these outcomes are related, there is prior evidence that their etiology does not entirely overlap. Efforts to directly differentiate risk across outcomes are uncommon, particularly among older, population-based cohorts.

METHODS

This research has been conducted using the UK Biobank. Data on individuals' self-reported history of non-suicidal self-injury only versus suicide attempt (maximum N = 6643) were analyzed. Applying LASSO and standard logistic regression, participants reporting one of these outcomes were assessed for differences across a range of sociodemographic, behavioral, and environmental features.

RESULTS

Sociodemographic features most strongly differentiated between the outcomes of non-suicidal self-injury only versus suicide attempt. Specifically, Black individuals were more likely to report a suicide attempt, as were those of mixed race, those endorsing higher levels of depressive symptoms or trauma history, and those who had experienced financial problems (odds ratios 1.02-3.92). Those more likely to engage in non-suicidal self-injury only were younger, female, had higher levels of education, those who resided with a partner, and those who had a recently injured relative.

LIMITATIONS

Differences in timing across correlates and outcomes preclude the ability to establish causal pathways.

CONCLUSIONS

The factors identified in the current study as differentially associated with non-suicidal self-injury only versus suicide attempt provide further evidence of at least partially distinct correlates, and warrant follow-up in independent samples to investigate causality.

Effects of ethnic density on the risk of compulsory psychiatric admission for individuals attending secondary care mental health services: evidence from a large-scale study in England

BACKGROUND

Black, Asian and minority ethnicity groups may experience better health outcomes when living in areas of high own-group ethnic density - the so-called 'ethnic density' hypothesis. We tested this hypothesis for the treatment outcome of compulsory admission.

METHODS

Data from the 2010-2011 Mental Health Minimum Dataset (N = 1 053 617) was linked to the 2011 Census and 2010 Index of Multiple Deprivation. Own-group ethnic density was calculated by dividing the number of residents per ethnic group for each lower layer super output area (LSOA) in the Census by the LSOA total population. Multilevel modelling estimated the effect of own-group ethnic density on the risk of compulsory admission by ethnic group (White British, White other, Black, Asian and mixed), accounting for patient characteristics (age and gender), area-level deprivation and population density.

RESULTS

Asian and White British patients experienced a reduced risk of compulsory admission when living in the areas of high own-group ethnic density [odds ratios (OR) 0.97, 95% credible interval (CI) 0.95-0.99 and 0.94, 95% CI 0.93-0.95, respectively], whereas White minority patients were at increased risk when living in neighbourhoods of higher own-group ethnic concentration (OR 1.18, 95% CI 1.11-1.26). Higher levels of own-group ethnic density were associated with an increased risk of compulsory admission for mixed-ethnicity patients, but only when deprivation and population density were excluded from the model. Neighbourhood-level concentration of own-group ethnicity for Black patients did not influence the risk of compulsory admission.

CONCLUSIONS

We found only minimal support for the ethnic density hypothesis for the treatment outcome of compulsory admission to under the Mental Health Act.

Thinking biases and their role in persecutory delusions: A systematic review

AIM

Thinking biases are posited to be involved in the genesis and maintenance of delusions. Persecutory delusions are one of the most commonly occurring delusional subtypes and cause substantial distress and disability to the individuals experiencing them. Their clinical relevance confers a rationale for investigating them. Particularly, this review aims to elucidate which cognitive biases are involved in their development and persistence.

METHODS

MEDLINE, Embase, PsycINFO and Global Health were searched from the year 2000 to June 2020. A formal narrative synthesis was employed to report the findings and a quality assessment of included studies was conducted.

RESULTS

Twenty five studies were included. Overall, 18 thinking biases were identified. Hostility and trustworthiness judgement biases appeared to be specific to persecutory delusions while jumping to conclusions, self-serving attributional biases and belief inflexibility were proposed to be more closely related to other delusional subtypes. While the majority of the biases identified were suggested to be involved in delusion maintenance, hostility biases, need for closure and personalizing attributional biases were believed to also have aetiological influences.

CONCLUSIONS

These findings show that some cognitive biases are specific to paranoid psychosis and appear to be involved in the formation and/or persistence of persecutory delusions.

Psychotic disorders in young adults with perinatally acquired HIV: a UK case series

BACKGROUND

Increasing numbers of children with perinatally acquired HIV (PaHIV) are transitioning into adult care. People living with behaviourally acquired HIV are known to be at more risk of psychosis than uninfected peers. Young adults living with PaHIV face numerous risk factors; biological: lifelong exposure to a neurotrophic virus, antiretroviral medication and immune dysfunction during brain development, and environmental; social deprivation, ethnicity-related discrimination, and migration-related issues. To date, there is little published data on the prevalence of psychotic illness in young people growing up with PaHIV.

METHODS

We conducted a retrospective case note review of all individuals with PaHIV aged over 18 years registered for follow up at a dedicated clinic in the UK (n = 184).

RESULTS

In total, 12/184 (6.5%), median age 23 years (interquartile range 21-26), had experienced at least one psychotic episode. The presentation and course of the psychotic episodes experienced by our cohort varied from short-lived symptoms to long term illness and nine (75%) appear to have developed a severe and enduring mental illness requiring long term care.

CONCLUSION

The prevalence of psychosis in our cohort was clearly above the lifetime prevalence of psychosis in UK individuals aged 16-34 years, which has been reported to be 0.5-1.0%. This highlights the importance of clinical vigilance regarding the mental health of young people growing up with PaHIV and the need to integrate direct access to mental health services within the HIV centres providing medical care.

A Systematic Review of Inequalities in the Mental Health Experiences of Black African, Black Caribbean and Black-mixed UK Populations: Implications for Action

BACKGROUND

Measurable differences in the experience and treatment of mental health conditions have been found to exist between different racial categories of community groups. The objective of this research was to review the reported mental health of Black African-Caribbean communities in the UK, determinants of mental health, and interventions to enhance their experiences of mental health services.

METHOD

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement was applied. To be included, papers must be published in a peer reviewed journal; report on adult populations (over 18) from any of Black African, Black Caribbean or Black mixed people in the UK; and assess (quantitative), or discuss (qualitative) mental health experiences, determinants of mental health, or interventions intended to enhance experiences of mental health services among the target population. The aims, inclusion criteria, data extraction, and data quality evaluation were specified in advance. Searches were conducted using EBSCO (PsychInfo; MEDLINE; CINAHL Plus; psychology and behavioural sciences collection). The search strategy included search terms relating to the aim. Risk of bias was assessed using a standard tool, records were organised using Endnote, and data were extracted and synthesised using Microsoft Excel.

RESULTS

Thirty-six studies were included, of which 26 were quantitative and six reported exclusively on Black participants. Black populations were less likely to access mental health support via traditional pathways due to stigma and mistrust of mental health services. Black Africans especially, sought alternative help from community leaders, which increased the likelihood of accessing treatment at the point of crisis or breakdown, which in turn increased risk of being detained under the Mental Health Act and via the criminal justice system.

DISCUSSION

Findings suggest a cycle of poor mental health, coercive treatment, stigma, and mistrust of services as experienced by Black communities. Evidence was limited by poorly defined ethnic categories, especially where Black populations were subsumed into one category. It is recommended that mental health services work collaboratively with cultural and faith communities in supporting Black people to cope with mental illness, navigate mental health pathways, and provide culturally appropriate advice.

The Role and Clinical Correlates of Complex Post-traumatic Stress Disorder in People With Psychosis

Traumatic experiences and post-traumatic stress are highly prevalent in people with psychosis, increasing symptom burden, decreasing quality of life and moderating treatment response. A range of post-traumatic sequelae have been found to mediate the relationship between trauma and psychotic experiences, including the "traditional" symptoms of post-traumatic stress disorder (PTSD). The International Classification of Diseases-11th Edition recognizes a more complex post-traumatic presentation, complex PTSD (cPTSD), which captures both the characteristic symptoms of PTSD alongside more pervasive post-traumatic sequelae known as 'disturbances in self-organization' (DSOs). The prevalence and impact of cPTSD and DSOs in psychosis remains to be explored. In the first study of this kind, 144 participants with psychosis recruited from North West United Kingdom mental health services completed measures assessing trauma, PTSD and cPTSD symptoms and symptoms of psychosis. Forty-percent of the sample met criteria for cPTSD, compared to 10% who met diagnostic criteria for PTSD. PTSD and DSOs mediated the relationship between trauma and positive symptoms, controlling for dataset membership. Both PTSD and DSOs mediated the relationship between trauma and affective symptoms but did not explain a significant proportion of variance in negative symptoms. Cognitive and excitative symptoms of psychosis did not correlate with trauma, PTSD or DSO scores. These findings indicate the possible value of adjunct therapies to manage cPTSD symptoms in people with psychosis, pending replication in larger epidemiological samples and longitudinal studies.

The role of attachment and dissociation in the relationship between childhood interpersonal trauma and negative symptoms in psychosis

Negative symptoms have an adverse impact on quality of life and functioning in psychosis. Service users with psychosis have identified negative symptoms as a priority for their recovery. Despite this, there is a lack of effective and targeted psychological interventions for negative symptoms and their underlying mechanisms remain poorly understood. Childhood trauma is a robust risk factor for positive symptoms in psychosis, but the association with negative symptoms is less well established. Our aim was to examine the association between childhood interpersonal trauma and negative symptoms and the psychological mediators of this relationship. Two hundred and forty participants experiencing psychosis completed validated self-report measures of childhood trauma, attachment, dissociation, compartmentalization, and symptoms. Mediation analyses showed that disorganized attachment and dissociative experiences mediated the association between childhood trauma and negative symptoms, when analysed individually and in a combined model. Models adjusted for age and positive and depressive symptoms. Avoidant attachment and compartmentalization were independently associated with negative symptoms but not childhood trauma and thus were not significant mediators. Childhood trauma was not independently associated with negative symptoms. This paper is the first to present empirical data to support a model implicating attachment and dissociation as important psychological processes in the link between childhood trauma and negative symptoms. These exploratory findings suggest that it may be beneficial to consider these relationships in trauma-informed formulations and interventions. Further longitudinal research is required to establish causality and test theoretical models of mechanisms in the pathway to negative symptoms.

Mental illness stigma after a decade of Time to Change England: inequalities as targets for further improvement

Background

England’s Time to Change programme to reduce mental health-related stigma and discrimination included a social marketing campaign using traditional and social media, and targeted middle-income groups aged 25–45 between 2009 and 2016. From 2017, the same age group on low to middle incomes were targeted, and the content focused on men’s mental health, by changing the advertising and adapting the ‘key messages’. This study investigates changes in stigma-related public knowledge, attitudes and desire for social distance in England since Time to Change began in 2008–19 and for 2017–19.

Methods

Using data from a face-to-face survey of a nationally representative quota sample of adults for England, we evaluated longitudinal trends in outcomes with regression analyses and made assumptions based on a simple random sample. The pre-existing survey used a measure of attitudes; measures of knowledge and desire for social distance were added in 2009.

Results

Reported in standard deviation units (95% CI), the improvement for knowledge for 2009–19 was 0.25 (0.19, 0.32); for attitudes, 2008–19, 0.32 (0.26, 0.39) and for desire for social distance, 2009–19 0.29 (0.23, 0.36). Significant interactions between year and both region and age suggest greater improvements in London, where stigma is higher, and narrowing of age differences. There were significant improvements between 2017 and 2019 in knowledge [0.09 (0.02, 0.16)] and attitudes [0.08 (0.02, 0.14)] but not social distance.

Conclusion

The positive changes support the effectiveness of Time to Change but cannot be definitively attributed to it. Inequalities in stigma by demographic characteristics present targets for research and intervention.

Evidence for interventions to promote mental health and reduce stigma in Black faith communities: systematic review

PURPOSE

There are significant documented inequalities for the Black community in the UK in relation to mental health care. Research has also indicated that cultural difference exists in pathways into, and engagement with, mental health services. To reduce inequalities and improve engagement with mental health services, it is important that professionals utilise culturally appropriate community networks to increase mental health awareness and reduce stigma. This systematic review considers research in Black faith settings, with two linked aims to review the evidence for the effectiveness of (i) mental health interventions, and (ii) other health stigma interventions as the latter have been implemented in Black faith settings. The review identified 'active ingredients' of interventions for this population that can be applied in future work. The authors seek to draw from the mental health and wider health stigma literature to inform the design of the ON TRAC project, a collaborative partnership between King's College London, South London and Maudsley NHS Foundation Trust and Black faith community groups in Southwark and Lambeth, London, in this currently under-researched area.

METHODS

A systematic search of ten major medical and social sciences databases was conducted in 2019, for studies on mental health or other health stigma interventions in Black faith settings. PRISMA guidelines were followed and search terms and search strategy ensured all possible studies were identified for review.

RESULTS

The review identified sixteen studies for inclusion. Ten were quantitative studies, four qualitative studies and two systematic reviews. Active ingredients of interventions included utilisation of 'bottom up' development of approaches and mental health champions. Multiple factors were found to influence effective implementation. Co-production and partnership working are key to ensure that an acceptable and accessible intervention is agreed.

CONCLUSION

Evidence for the effectiveness of interventions focused on mental health awareness and stigma reduction in the Black faith community is limited due to the low quality of studies. This review sheds light on the lessons learnt and necessary key requirements for interventions that can guide future projects.

Characteristics associated with the risk of psychosis among immigrants and their descendants in France

OBJECTIVE

To explore the sociodemographic characteristics that might explain the increased incidence of psychosis among immigrants and their descendants in France.

METHODS

Data were collected for all subjects with first contact for psychosis aged between 18 and 64 years, in two catchment areas in the Paris region. Incidence rates (IR) and incidence rate ratios (IRR) were adjusted for gender and age.

RESULTS

During 805,396 persons-year at risk, we identified 321 cases of first-episode psychosis, of which 129 were immigrants and 78 descendants of immigrants. We found that the geographic origin was associated with the risk of psychosis although generation has little impact. Sub-Saharan African immigrants and their descendants showed the highest risk (IRR = 3.1 and IRR = 2.9, respectively). We observed that living in deprived areas increased the incidence of psychosis (IRR = 1.3, 95CI%: 1.0-1.6), particularly among immigrants (IRR = 1.6; 95% CI: 1.1-2.5). Finally, our study showed that subjects having unstable housing (a proxy for "hard to count population") could inflate the incidence rates among immigrants.

CONCLUSION

The current study shows that the increased risk of psychosis in groups with an immigration background in France is associated with their origin and highlights the importance of socioeconomic factors in modulating this risk.

The prevalence of mental illness and unmet needs of police custody detainees

BACKGROUND

Internationally, there is evidence of high rates of mental disorders amongst police custody detainees but this literature is limited, and there has been little research into the unmet needs of police detainees in the UK, or elsewhere. Such research could support better focussed interventions for improving health and recidivism outcomes.

AIM

To examine psychiatric and developmental morbidity amongst police detainees, and ascertain differences in need between morbidity categories.

METHOD

We used a cross-sectional study design and interviewed a 40% sample of people entering police custody in one South London police station over a 2-week period. A series of standardised measures was administered to screen for the presence of mental illness, general health and social care needs.

RESULTS

A cohort of 134 people was generated, of whom nearly one-third (39, 29%) had current mental illness (major depression and/or psychosis); more had a lifetime diagnosis (54, 40%). Just under a fifth met the threshold for post-traumatic stress disorder (11, 8%). Clinically relevant alcohol or daily cannabis use affected about one quarter of the sample. Twenty-one percent (or 28) screened positive for personality disorder, 11% (or 15) for attention deficit hyperactivity disorder and 4% (6) for intellectual disability. Nearly one-fifth (24, 18%) were at risk for suicide. Those with psychosis, and those deemed at risk for suicide, had the highest levels of unmet need and, indeed, overall need. The most frequent unmet need was for accommodation.

CONCLUSION

Our findings not only confirm high rates of mental health problems amongst police detainees but also demonstrate their high risk of suicide and high levels of unmet need, especially as regards accommodation. This underscores the need to provide mental health services in police stations, to help identify and resolve these issues at this early stage in the criminal justice system. Extending accommodation capacity to help some arrestees may help to save lives and interrupt cycling through the criminal justice system.

Exploring service user and family perspectives of a Culturally adapted Family Intervention (CaFI) for African-Caribbean people with psychosis: A qualitative study

OBJECTIVES

In the UK, people of African-Caribbean background have the highest rates of psychosis and greatest inequity in mental health services of all ethnicities. National policies have highlighted the lack of evidence-based psychological interventions for this group. The aim of this study was to examine the acceptability of a novel Culturally adapted Family Intervention (CaFI) for African-Caribbean individuals diagnosed with non-affective psychosis and their relatives.

DESIGN

A qualitative design.

METHODS

Semi-structured interviews conducted with 22 service users and 12 family members following participation in CaFI. The interview topic guide included perceptions of the needs and benefits of CaFI; usefulness, cultural specificity and accessibility of CaFI therapy and supporting materials; content and delivering of CaFI sessions; views and experiences of working with CaFI therapists; and perceived barriers and facilitators to implementation.

RESULTS

Deductive framework analysis identified three main themes for service users: perceived benefits, barriers and limitations, and delivery of the therapy. Four themes were identified for family members: perceived benefits, perceptions of therapists, delivery of therapy, and accessibility of therapy content, supporting materials, and cultural appropriateness.

CONCLUSIONS

CaFI was found to be an acceptable intervention for African-Caribbean service users with psychosis and their relatives. Family interventions considering the needs of ethnic and cultural groups have the potential to improve the mental health care and experiences of service users and their families.

PRACTITIONER POINTS

The Culturally adapted Family Intervention (CaFI) was viewed as acceptable to African-Caribbean service users with psychosis and their families. Through adapting interventions to be more culturally sensitive, it is possible to enhance the care of those who typically have poor engagement with mental health services. In-keeping with their ethos of individualized care delivery, mental health services should place more emphasis on being able to offer appropriate, culturally adapted interventions to their service users.

Temporal trends in psychotic symptoms: Repeated cross-sectional surveys of the population in England 2000-14

BACKGROUND

The number of antipsychotic prescriptions dispensed annually in England has increased substantially over the past decade. It is not known whether this is due to changes in prescribing practices, or an increase in the prevalence of psychosis. To our knowledge, no previous studies have investigated temporal trends in prevalence of psychotic symptoms in non-clinical populations.

METHODS

We used data from the nationally representative Adult Psychiatric Morbidity Surveys 2000, 2007 and 2014 to (1) test whether the prevalence of psychotic symptoms increased between 2000 and 2014; (2) compare prevalence of psychotic symptoms to the prevalence of being prescribed antipsychotic medication; and (3) identify correlates of experiencing psychotic symptoms.

RESULTS

There was a small increase in the prevalence of psychotic symptoms in 2014 compared to 2000 (prevalence in 2000 5.6%, 95% confidence intervals (CI) 5.1% to 6.2%; prevalence in 2014 6.8%, 95% CI 6.1% - 7.6%). This corresponded to an adjusted odds ratio of 1.2 (95% CI 1.02-1.40, p=0.026) for experiencing psychotic symptoms in 2014 compared to 2007. By comparison, antipsychotic medication use doubled over this period (prevalence in 2000 0.6%, 95% CI 0.4%-0.7%; prevalence in 2014 1.2% 95% CI 0.9%-1.5%; aOR 2.22 (1.52-3.25) p<0.001). Correlates of reporting psychotic symptoms included ethnic minority identity, younger age, lower social class, alcohol and cannabis use, and any psychiatric diagnosis.

CONCLUSIONS

While the rates of antipsychotic prescription doubled between 2000 and 2014, the odds of having psychotic symptoms rose only slightly. The reasons for this warrant further investigation.

Migration and Psychosis: Specificity and Burden on the Mental Health System in Italy

In the last years, there has been a huge migratory flow to Italy. Migration is a risk factor for the development of psychopathology, especially psychosis and posttraumatic stress disorder. We aimed at investigating the burden and characteristics of psychotic features among immigrants in Lombardy, one of the most involved regions. A total of 7819 patients had at least one psychiatric appointment in 2013, 10.3% of them where immigrants. Patients from Africa showed a significant higher rate of psychosis, psychiatric onset, compulsory admissions, and number of professional appointments. Our result can confirm a cultural specificity of psychotic manifestations and their burden on the mental health system.

Dementia in People from Ethnic Minority Backgrounds: Disability, Functioning, and Pharmacotherapy at the Time of Diagnosis

OBJECTIVES

Increasingly, older populations in the United Kingdom and other well-resourced settings are ethnically diverse. Despite a concern that the prevalence of dementia is expected to rise, very little is known about the association of ethnicity and dementia among aging older adults. The current study aimed to compare ethnic group differences in symptom profile, functioning and pharmacotherapy at dementia diagnosis.

DESIGN

Cross-sectional study of patient characteristics at the point of dementia diagnosis.

SETTING AND PARTICIPANTS

In total, 12,154 patients aged 65 years or older diagnosed with dementia in Southeast London between 2007 and 2015.

METHODS

Data were extracted from the Clinical Record Interactive Search system, which provides anonymized access to the electronic health records of a large mental healthcare provider in Southeast London. Patients from ethnic minority backgrounds were compared with white British individuals on mental and physical well-being, functional scales and medications prescribed at dementia diagnosis, as well as subtype of dementia documented anywhere in the record.

RESULTS

Compared with white British patients, Black African and Black Caribbean patients were more likely to present with psychotic symptoms and were less likely to have an antidepressant prescribed; white Irish patients had higher rates of substance/alcohol use and depressive symptoms were more prevalent in South Asian patients; all ethnic minority groups had higher odds of polypharmacy; and vascular dementia diagnoses were more common in Black and Irish ethnic minority groups.

CONCLUSIONS AND IMPLICATIONS

At dementia diagnosis, there are substantial differences in noncognitive mental health symptoms and pharmacotherapy across ethnic minority groups and compared with the white British majority population. Some of these differences might reflect access/treatment inequalities or implicit unconscious bias related to ethnicity, influencing both. They need to be taken into consideration to optimize pathways into care and personalize assessment and management.

An ethnic-group comparison of caregiver beliefs about early psychotic illness in a UK sample: Implications for evidence-based caregiver interventions

This study aimed to investigate potential ethnic differences in cognitive responses to caregiving in psychosis that might be relevant to the delivery of caregiver interventions for difficulties related to psychosis. We compared cross-sectional outcomes across early-stage caregivers who self-identified as white British (n = 37) and those who self-identified as black African or Caribbean (n = 41) using United Kingdom (UK) census ethnicity criteria. Self-report questionnaires were used to examine caregiver beliefs about psychosis, including the perceived causes, consequences, timeline, the degree of control that patients have over their difficulties, as well as their appraisals of caregiving. Caregivers from black African or Caribbean backgrounds reported a significantly shorter expected duration of illness than white British caregivers. They were also more likely to cite psychosocial causes (e.g., relationship issues), and less likely to cite biological and genetic causes, as their principal explanations for problems. However, overall differences in perceived causes of illness between ethnicities were not significant, despite the power in this sample to detect medium-sized effects. Factors associated with ethnicity may contribute to individual differences in explanatory models of illness and in experiences of caregiving. A degree of sensitivity to the range of views that people might hold about psychosis may help to engage caregivers from diverse ethnic backgrounds.

Where next for understanding race/ethnic inequalities in severe mental illness? Structural, interpersonal and institutional racism

In this article we use the example of race/ethnic inequalities in severe mental illness to demonstrate the utility of a novel integrative approach to theorising the role of racism in generating inequality. Ethnic minority people in the UK are at much greater risk than White British people of being diagnosed with a severe - psychosis related - mental illness, and this is particularly the case for those with Black Caribbean or Black African origins. There is entrenched dispute about how we might understand the drivers of this inequality. To address this dispute we build on, and to a certain extent refine, established approaches to theorising structural and institutional racism, and integrate this within a theoretical framework that also incorporates racist/discriminatory interactions (interpersonal racism). We argue that this provides a conceptually robust and thorough analysis of the role of inter-related dimensions of racism in shaping risks of severe mental illness, access to care, and policy and practice responses. This analysis carries implications for a broader, but integrated, understanding of the fundamental drives of race/ethnic inequalities in health and for an anti-racism public health agenda.

Public knowledge, attitudes, social distance and reporting contact with people with mental illness 2009-2017

BACKGROUND

Our aim was to investigate patterns of change in public knowledge, attitudes, desire for social distance and reporting having contact with people with mental health problems in England during the Time to Change (TTC) programme to reduce stigma and discrimination 2009-2017.

METHODS

Using data from an annual face-to-face survey of a nationally representative quota sample of adults, we evaluated longitudinal trends of the outcome measures with regression analyses and made assumptions on the basis of a simple random sample. We tested interactions between year and demographic subgroups.

RESULTS

There were improvements in all outcomes in 2017 compared with baseline measures (2008 or 2009). Reported in s.d. units [95% confidence interval (CI)], the improvement for knowledge was 0.17 (0.10-0.23); for attitudes 0.25 (0.18-0.31); and for social distance 0.29 (0.23-0.35). A higher likelihood of reporting contact was also associated with most recent survey year (odds ratio 1.47, 95% CI 1.27-1.71). Statistically significant interactions between year and region of England suggest greatest improvements in attitudes and intended behaviour in London, where both outcomes were significantly worse in the early years of the survey. However, for attitudes, this interaction was only significant among women. Other significant interactions suggest that attitudes improved most in the target age group (25-44).

CONCLUSIONS

The results provide support for the effectiveness of TTC across demographic groups. However, other societal changes may influence the results, such as the increasing prevalence of common mental disorder in young women.

Modifying illness beliefs in recent onset psychosis carers: Evaluating the impact of a cognitively focused brief group intervention in a routine service

AIMS

At first-episode psychosis (FEP), many patients will be routed within familial networks and supported by informal carers who are predominately close family members such as parents. Carer burden, distress and poorer coping styles are associated with different illness beliefs. The current study sought to examine the impact and acceptability of a 3 session, cognitively informed, group intervention targeting illness beliefs previously linked to distress and poorer caregiving experiences in FEP carers.

METHODS

Carers attending a routine FEP service were invited to attend the group intervention and completed a measure of illness beliefs at baseline and post intervention.

RESULTS

Data on 68 carers with complete datasets are presented. Carers were predominately females (64.2%). Group attendance was linked to positive improvements in carer baseline beliefs about the negative consequences of the illness for the patient and themselves, attributions of blame about the illness to the patient and themselves and their overall understanding about the illness. Significant improvements in their understanding of the illness timeline and course, and confidence in dealing with difficulties were also identified.

CONCLUSIONS

A cognitively informed group approach to targeting the less adaptive illness beliefs reported by FEP carers may offer an effective and acceptable pathway to facilitate their understanding of the illness and adjustment. Further studies using controlled designs are required.

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.

Culturally adapted Family Intervention (CaFI): case examples from therapists’ perspectives

This paper describes three case examples from a recent trial of family intervention specifically designed for people of African-Caribbean descent. These examples, told from the therapists’ perspectives, highlight key components of the intervention and issues that arose in working with this client group. Findings from the study suggest that it is possible to engage this client-group in family therapy similar to traditional evidenced-based family interventions, although as illustrated in the paper, it is important that therapists pay attention to themes that are likely to be particularly pertinent for this group, including experiences of discrimination and mistrust of services. The use of Family Support Members, consisting of members of the person's care team or volunteers recruited from the community, may also help support people to engage in therapy in the absence of biological relatives.

HIV prevalence among first-presentation psychotic patients

OBJECTIVES

First-episode psychosis is a frequent emergency department (ED) presentation that may potentially be secondary to an underlying life-threatening HIV-related condition. The aim of this study was to determine the prevalence of HIV infection in patients presenting with a first episode of psychosis.

METHODS

Medical records of 159 consecutive African, Asian, White and mixed ethnicity patients presenting to a tertiary academic hospital ED with a first episode of psychotic features were prospectively reviewed.

RESULTS

Of the 159 subjects, 63 (39.6%) were HIV positive. An underlying medical condition was the most common aetiology of psychosis in both HIV-positive (84.2%) and HIV-negative (35.4%) subjects, but was significantly more common in HIV-positive individuals (P < 0.001). Substance-induced psychotic disorders and other primary psychiatric disorders were significantly more common in subjects without HIV infection (P < 0.001 and P < 0.001, respectively). While there were more men in the HIV-negative group (66.7%), gender distribution was almost equal in the HIV-infected group (49.2% male). Overall, as well as in both groups, most subjects were of African race, were unemployed and had not completed high school.

CONCLUSIONS

Co-occurrence of HIV infection was a frequent finding in first-episode psychotic individuals residing in a high-prevalence HIV setting. These individuals are more likely to have an underlying medical condition precipitating the onset of psychosis, not to have been initiated on antiretroviral therapy and to present with a low CD4 cell count and high HIV viral load.

Assessing needs for psychiatric treatment in prisoners: 1. Prevalence of disorder

BACKGROUND

High levels of psychiatric morbidity in prisoners have important implications for services. Assessing Needs for Psychiatric Treatment in Prisoners is an evaluation of representative samples of prisoners in a male and a female prison in London. This paper reports on the prevalence of mental disorders. In a companion paper, we describe how this translates into mental health treatment needs and the extent to which they have been met.

METHODS

Prisoners were randomly sampled in a sequential procedure based on the Local Inmate Data System. We interviewed roughly equal numbers from the following groups: male remand; male sentenced prisoners (Pentonville prison); and female remand; female sentenced prisoners (Holloway prison). Structured assessments were made of psychosis, common mental disorders, PTSD, personality disorder and substance abuse.

RESULTS

We interviewed 197 male and 171 female prisoners. Psychiatric morbidity in male and female, sentenced and remand prisoners far exceeded in prevalence and severity than in equivalent general population surveys. In particular, 12% met criteria for psychosis; 53.8% for depressive disorders; 26.8% for anxiety disorders; 33.1% were dependent on alcohol and 57.1% on illegal drugs; 34.2% had some form of personality disorder; and 69.1% had two disorders or more. Moreover, in the year before imprisonment, 25.3% had used mental health services.

CONCLUSIONS

These rates of mental ill-health and their similarity in remand and sentenced prisoners indicate that diversion of people with mental health problems from the prison arm of the criminal justice system remains inadequate, with serious consequences for well-being and recidivism.

Prevalence and treatment of common mental disorders in the English national population, 1993-2007

BACKGROUND

The National Psychiatric Morbidity Surveys include English cross-sectional household samples surveyed in 1993, 2000 and 2007.

AIMS

To evaluate frequency of common mental disorders (CMDs), service contact and treatment.

METHOD

Common mental disorders were identified with the Clinical Interview Schedule - Revised (CIS-R). Service contact and treatment were established in structured interviews.

RESULTS

There were 8615, 6126 and 5385 participants aged 16-64. Prevalence of CMDs was consistent (1993: 14.3%; 2000: 16.0%; 2007: 16.0%), as was past-year primary care physician contact for psychological problems (1993: 11.3%; 2000: 12.0%; 2007: 11.7%). Antidepressant receipt in people with CMDs more than doubled between 1993 (5.7%) and 2000 (14.5%), with little further increase by 2007 (15.9%). Psychological treatments increased in successive surveys. Many with CMDs received no treatment.

CONCLUSIONS

Reduction in prevalence did not follow increased treatment uptake, and may require universal public health measures together with individual pharmacological, psychological and computer-based interventions.

At risk or not at risk? A meta-analysis of the prognostic accuracy of psychometric interviews for psychosis prediction

An accurate detection of individuals at clinical high risk (CHR) for psychosis is a prerequisite for effective preventive interventions. Several psychometric interviews are available, but their prognostic accuracy is unknown. We conducted a prognostic accuracy meta-analysis of psychometric interviews used to examine referrals to high risk services. The index test was an established CHR psychometric instrument used to identify subjects with and without CHR (CHR+ and CHR-). The reference index was psychosis onset over time in both CHR+ and CHR- subjects. Data were analyzed with MIDAS (STATA13). Area under the curve (AUC), summary receiver operating characteristic curves, quality assessment, likelihood ratios, Fagan's nomogram and probability modified plots were computed. Eleven independent studies were included, with a total of 2,519 help-seeking, predominately adult subjects (CHR+: N=1,359; CHR-: N=1,160) referred to high risk services. The mean follow-up duration was 38 months. The AUC was excellent (0.90; 95% CI: 0.87-0.93), and comparable to other tests in preventive medicine, suggesting clinical utility in subjects referred to high risk services. Meta-regression analyses revealed an effect for exposure to antipsychotics and no effects for type of instrument, age, gender, follow-up time, sample size, quality assessment, proportion of CHR+ subjects in the total sample. Fagan's nomogram indicated a low positive predictive value (5.74%) in the general non-help-seeking population. Albeit the clear need to further improve prediction of psychosis, these findings support the use of psychometric prognostic interviews for CHR as clinical tools for an indicated prevention in subjects seeking help at high risk services worldwide.

Adult attention deficit hyperactivity symptoms and psychosis: Epidemiological evidence from a population survey in England

Despite both having some shared features, evidence linking psychosis and adult attention deficit hyperactivity disorder (ADHD) is sparse and inconsistent. Hypotheses tested were (1) adult ADHD symptoms are associated with auditory hallucinations, paranoid ideation and psychosis (2) links between ADHD symptoms and psychosis are mediated by prescribed ADHD medications, use of illicit drugs, and dysphoric mood. The Adult Psychiatric Morbidity Survey 2007 (N=7403) provided data for regression and multiple mediation analyses. ADHD symptoms were coded from the ADHD Self-Report Scale (ASRS). Higher ASRS total score was significantly associated with psychosis, paranoid ideation and auditory hallucinations despite controlling for socio-demographic variables, verbal IQ, autism spectrum disorder traits, childhood conduct problems, hypomanic and dysphoric mood. An ASRS score indicating probable ADHD diagnosis was also significantly associated with psychosis. The link between higher ADHD symptoms and psychosis, paranoia and auditory hallucinations was significantly mediated by dysphoric mood, but not by use of amphetamine, cocaine or cannabis. In conclusion, higher levels of adult ADHD symptoms and psychosis are linked and dysphoric mood may form part of the mechanism. Our analyses contradict the traditional clinical view that the main explanation for people with ADHD symptoms developing psychosis is illicit drugs.
