Risk of Psychosis Among Refugees: A Systematic Review and Meta-analysis

Refugee Migration Background and Healthcare Contacts Prior to First-Episode Psychosis in Young Adults in Denmark and Sweden: Are Patterns Consistent Across Countries?

INTRODUCTION

The objective of this study was to examine group differences in healthcare contacts prior to a first diagnosis of non-affective psychotic disorders (NAPDs) comparing young refugees settled in Denmark and Sweden before turning 18 non-refugee migrants and native-born individuals.

METHODS

Using nationwide register data, we identified all individuals aged 18-35 who received an NAPD diagnosis during 2006-2018. Healthcare contacts for other psychiatric disorders were categorised as inpatient, outpatient (grouped by discharge diagnosis) or dispensed antidepressant medication. Logistic regression was used in each country to compare contacts within 12 months prior to NAPD diagnosis, yielding odds ratios (OR) and corresponding 95% confidence intervals (CI), while standardised prevalence ratios (SPR), reported in percentages, were used to compare healthcare contact across countries.

RESULTS

We included 11,679 individuals in Denmark and 11,088 in Sweden. The likelihood of prior contact of any type was lower in both countries for both refugees [Denmark: OR = 0.75(CI: 0.63, 0.90); Sweden: OR = 0.61(CI: 0.55, 0.68)] and non-refugee migrants [Denmark: OR = 0.78(CI: 0.64, 0.95); Sweden: OR = 0.55(CI: 0.49, 0.62)] compared with majority peers. The largest differences were observed for dispensed antidepressants in both countries [Denmark: ORrefugees = 0.58(CI: 0.47, 0.71); Sweden: ORrefugees = 0.52(CI: 0.45, 0.61)]. Outpatient contacts in particular were more common in Sweden than in Denmark across all groups [SIRrefugees = 151% (CI: 125, 180)].

CONCLUSION

Young refugees and non-refugee migrants in both Denmark and Sweden were less likely to have healthcare contact for other psychiatric disorders prior to NAPD onset than host populations. As healthcare contacts offer opportunities to identify treatment needs early, these groups may be vulnerable to delays in the pathway to treatment.

Salivary cortisol measures across the clinical stages of psychosis: An individual participant data (IPD) meta-analysis

BACKGROUND

Studies of salivary cortisol levels in psychosis have yielded inconsistent findings, which may be attributable to heterogeneity in cortisol measurement, illness stage, and approaches to dealing with sampling factors and potential confounders. To address these issues, we performed an individual participant data (IPD) meta-analysis comparing individuals at different stages of psychosis to controls using five different salivary cortisol measures and explored potential effect modifiers.

METHODS

Salivary cortisol data from five London-based cohorts were used to derive the cortisol awakening response, total daytime cortisol output, basal cortisol, and diurnal slope measures (wake-to-evening and peak-to-evening). Linear regression models were first performed to obtain standardised beta coefficients (β), representing the difference in each cortisol metric between each clinical stage group (cases) and healthy individuals (controls) after accounting for relevant sampling factors; we then used random-effects meta-analyses and meta-regression models to investigate the effect of psychosis stage and sample characteristics on effect sizes.

RESULTS

Data were available for 352 individuals distributed across psychosis clinical stages (1a - distress disorder: N = 35; 1b - clinical high-risk for psychosis: N = 90; 2a - first-episode psychosis: N = 197; 2b - single episode remitted: N = 5; 3 - relapsing/remitting illness: N = 18; 4 - severe and persistent illness: N = 7) and 292 controls. A significant overall main effect of clinical stage on peak-to-evening diurnal slope was observed (χ2=12.83, p = 0.025), with both the clinical high-risk (β=0.21, 95 % CI: 0.06, 0.36) and first-episode psychosis (β=0.20, 95 % CI: 0.10, 0.31) groups characterised by flatter slopes than controls. The clinical stage groups and controls did not differ on any other cortisol measure. Several sample characteristics were significantly associated with diurnal slope effect sizes, but after accounting for clinical stage, only the association between mean age in cases and wake-to-evening diurnal slope retained significance.

CONCLUSION

Clinical high-risk and first-episode psychosis participants differed from healthy controls in the peak-to-evening diurnal cortisol slope. This measure has not been examined in these populations before, and its potential predictive and prognostic utility for psychotic disorders merits further investigation.

Acculturation stress and mental health outcomes in a sample of migrant inpatients: Findings from a naturalistic study

INTRODUCTION

Migrants face numerous risk factors for mental disorders, including stressors and traumatic events during the pre-, peri-, and post-migratory phases. Acculturation stress, a significant post-migratory stressor, can adversely affect mental health during the cultural adaptation process. This study aims to assess the clinical implications of acculturation stress in migrants admitted to a psychiatric intensive care unit, with a focus on identifying predictors of acculturative stress and their impact on clinical outcomes.

METHODS

We conducted a retrospective study of 268 immigrant patients hospitalized between 2004 and 2019 at the psychiatric inpatient unit of the University of Foggia. We collected socio-demographic and clinical data using ad hoc schedules and validated assessment instruments, including the Brief Psychiatric Rating Scale (BPRS), the Global Assessment of Functioning (GAF), and the Clinical Global Impression (CGI). Diagnoses were based on DSM-IV-TR/DSM-5 criteria. We analyzed associations between demographic and clinical characteristics of patients reporting acculturative stress and those not reporting it, using appropriate statistical methods.

RESULTS

The majority of patients were diagnosed with affective (45.1%) or psychotic disorders (31.7%), with 57.1% experiencing their first psychiatric episode. Acculturation stress was reported by 51.9% of patients (N = 139), predominantly among males (71.9%), single individuals (80.9%), and those of Islamic faith (56.8%). Patients experiencing acculturation stress were more likely to be unemployed (57.6%) and without a residence permit (63.3%). This stress was particularly prevalent among patients with psychotic disorders (25.9%) and first-episode psychiatric cases (64.7%). At discharge, patients with acculturation stress showed less improvement on CGI, GAF, and BPRS scores compared to those without such stress.

CONCLUSIONS

Acculturation stress is influenced by several socio-demographic factors and is crucial for the full symptomatic remission of migrant patients. Culturally-oriented mental health services, including language and cultural integration programs, are essential in reducing acculturative stress and improving the overall well-being of immigrants.

War Exposure and DNA Methylation in Syrian Refugee Children and Adolescents

Importance

Exposure to war is associated with poor mental health outcomes. Adverse and traumatic experiences can lead to long-lasting DNA methylation changes, potentially mediating the link between adversity and mental health. To date, limited studies have investigated the impact of war on DNA methylation in children or adolescents, hampering our understanding of the biological impact of war exposure.

Objective

To identify salivary DNA methylation differences associated with war exposure in refugee children and adolescents.

Design, Setting, and Participants

This cohort study included Syrian refugee children and adolescents, and their primary caregiver were recruited from tented settlements in Lebanon. Data collection was carried out in 2 waves, 1 year apart, from October 2017 to January 2018 and October 2018 to January 2019. Children and their caregiver were interviewed, and children provided saliva samples for DNA extraction. Data analysis was conducted in 2022, 2023, and 2024.

Exposure

War exposure assessed by interviewing children and their caregiver using the War Events Questionnaire.

Main Outcomes and Measures

Salivary DNA methylation levels were assayed with the Infinium MethylationEPIC BeadChip (Illumina). Epigenetic aging acceleration was estimated using a set of preexisting epigenetic aging clocks. A literature search was conducted to identify previously reported DNA methylation correlates of childhood trauma.

Results

The study population included 1507 children and adolescents (mean [SD] age, 11.3 [2.4] years; age range, 6-19 years; 793 female [52.6%]). A total of 1449 children provided saliva samples for DNA extraction in year 1, and 872 children provided samples in year 2. Children who reported war events had a number of differentially methylated sites and regions. Enrichment analyses indicated an enrichment of gene sets associated with transmembrane transport, neurotransmission, and intracellular movement in genes that exhibited differential methylation. Sex-stratified analyses found a number of sex-specific DNA methylation differences associated with war exposure. Only 2 of 258 (0.8%) previously reported trauma-associated DNA methylation sites were associated with war exposure (B = -0.004; 95% CI, -0.005 to -0.003; Bonferroni P = .04 and B = -0.005; 95% CI, -0.006 to -0.004; Bonferroni P = .03). Any war exposure or bombardment was nominally associated with decreased epigenetic age using the Horvath multitissue clock (B = -0.39; 95% CI, -0.63 to -0.14; P = .007 and B = -0.42; 95% CI, -0.73 to -0.11; P = .002).

Conclusions and Relevance

In this cohort of Syrian refugee children and adolescents, war exposure was associated with a small number of distinct differences in salivary DNA methylation.

Schizotypal dimensions by migrant status in the general population: An exploratory study

Migrant status and ethnic minority background have been associated with increased risk for psychosis. However, it remains unclear if such association exists with subclinical forms of psychosis. In two general population samples, totaling 460 subjects, we investigated whether migrant status and/or ethnicity predict self-reported positive, negative and/or disorganized dimensions of psychosis (as measured by the SPQ-B). In comparison to the reference population, we observed higher scores in the negative dimension among both first and second-generation migrants as well as in some ethnic minority groups (particularly North Africa and French overseas). Our findings highlight the need to understand the mechanisms underlying this association between negative schizotypal traits and migrant/ethnic minority status. The fact that migration/ethnicity are associated with both psychotic disorders and subclinical manifestations of psychosis also support the psychosis continuum theory. The higher rates of negative schizotypal traits in these populations underscores the necessity for tailored policies and interventions to enhance mental health and prevent the transition to psychosis in these subgroups.

Prevalence of mental disorders and related risk factors in refugees and asylum seekers in Campania

Introduction

In recent years, the increasing presence of refugees and asylum seekers displaced from their country of origin, determined significant social, economic, humanitarian and public health implications in host countries, including Italy. These populations are exposed to several potential stressful experiences which make them vulnerable to psychological distress. In fact, the majority of studies addressing the topic found a higher prevalence of mental disorders, especially post-traumatic stress disorder and major depressive disorder, in refugees and asylum seekers with respect to the general population. However, heterogeneous prevalence rates have been reported among studies, due to methodological factor as well as to the impact of a variety of risk factors related to stressful experiences lived in the country of origin, during the migration journey and in the host country.

Objectives

The aim of the present study was to assess the prevalence of the main psychiatric diagnoses in a large group of adult refugees and asylum seekers (N=303) in the reception centers of two provinces of the Campania region, as well as to investigate the impact of potential risk factors on the occurrence of psychiatric disorders.

Methods

The diagnosis of psychiatric disorders and the identification of subjects at high risk to develop psychosis were carried out by means of structured diagnostic interviews. The following variables were explored as potential risk/protective factors to the occurrence of psychiatric disorders: socio-demographic variables, migration status (refugees/asylum seekers) and characteristics of the reception center,assessed by means of an ad hoc questionnaire; cognitive indices assessed by using standardized neuropsychological tests; traumatic experiences and level of political terror in the country of origin, assessed by means of reliable and valid self-report questionnaires.

Results

At least one mental disorder was found in 29.7% of the sample. Most prevalent diagnoses were depressive disorders, anxiety disorders and PTSD. Women showed, with respect to men, a higher prevalence of anxiety disorders, higher trauma levels, and came from more at-risk countries. Higher trauma levels, better cognitive abilities and unemployment and refugee status were associated to the presence of a current psychiatric disorder in the whole sample.

Conclusions

Our findings showed a higher prevalence of depressive disorders and PTSD in the sample of refugees and asylum seekers with respect to the general population and highlighted the role of potential risk factors whose identification may guide the implementation of preventive strategies and early treatments in these people.

[Climate crisis and psychiatry]

BACKGROUND

The climate crisis is increasingly leading to negative consequences for mental health and is of growing importance for psychiatric and psychotherapeutic care.

OBJECTIVE

The effects of the climate crisis on mental health and its significance for psychiatric and psychotherapeutic care are presented. Recommendations for sustainability in psychiatric and psychotherapeutic practice are provided.

MATERIAL AND METHODS

A narrative review of the literature was conducted for this article.

RESULTS

The climate crisis has direct, indirect and intersectional negative effects on mental health. Sustainable and preventive recommendations for the practice include promoting health literacy, faster access to psychotherapy and online counselling, supporting social networks, promoting employment and reducing poverty, homelessness and social isolation. It is recommended to increase the proportion of outpatient care and to streamline administrative processes. The use of disposable products should be minimized and the application of instrumental diagnostics and materials should be optimized according to guidelines. Digital interventions should be considered more frequently in the clinical practice and sustainable facility management should be improved. Access to green spaces for the general population and patients should be facilitated.

CONCLUSION

Due to the negative impact of the climate crisis on mental health, sustainability should be promoted in psychiatric and psychotherapeutic care.

Adolescents with first-episode psychosis and clinical high risk in the Province of Ferrara: an audit on the implementation of a specialised early intervention program

OBJECTIVE

The first-episode psychosis (FEP) and clinical high-risk (CHR) team within the child and adolescent mental health (CAMH) service receives referrals by psychiatric units, CAMH service, schools, and general practitioners. This audit evaluated the implementation of the FEP-CHR team in Ferrara, Italy.

METHODS

The FEP-CHR team provides standardised assessment and up to 2-year individualised treatment including pharmacological prescription, cognitive-behavioral psychotherapy, and vocational activities. Data regarding access and pathways to care, assessment, and outcome of all patients admitted to this service from January 2019 to June 2023 were analysed. Descriptive statistics were reported and discussed.

RESULTS

The service admitted 29 patients (19 FEP, 10 CHR), mostly females. FEP referrals primarily came from families via general practitioners, while half of CHR patients were already receiving CAMH care. One in three in the total sample had psychiatric hospitalisation during treatment. At discharge, most transitioned to usual or specialised mental health care and five patients achieved full recovery.

CONCLUSIONS

The audit revealed a lower-than-expected incidence rate, a sub-optimal adherence to the standardised assessment, and a need for improved outcome monitoring. It promoted quality improvement initiatives including professional training to improve psychiatric differential diagnosis, drug prescribing, and transition to adult psychiatric services.

Involuntary admissions for non-affective psychotic disorders in young refugees and peers in Denmark: A population cohort study

INTRODUCTION

People with psychotic disorders are at increased risk of experiencing involuntary hospital admissions relative to other psychiatric patients. Within this group, refugees and other minority groups may be at even greater risk. However, little is known about the role of migration background in the risk of involuntary admissions around the time of first psychosis-related treatment.

METHOD

We utilized nationwide administrative data from Denmark covering the period 2006-2018. We included all persons aged 18-35 years in first treatment for psychotic disorders [inpatient and hospital-based outpatient settings (N = 11,871)]. We estimated odds ratios (OR) of any involuntary inpatient admission within three months of first treatment using logistic regression, and rate ratios (RR) of further involuntary admissions, total number of involuntary admissions, and days of involuntary care among patients initially admitted involuntarily using Poisson regression. We compared refugees with majority peers (native-born with native-born parent), other migrants, and descendants of non-refugee migrants.

RESULTS

Compared with the majority group, refugees, non-refugee migrants and descendants were at increased risk of involuntarily admissions (ORrange = 2.12-2.69). Differences in sex, age, education, household income and family situation did not explain these disparities. In contrast, the risk of subsequent involuntary care did not differ between groups (RRrange = 0.77-1.31).

CONCLUSIONS

The findings highlight the need to review if and why processes of needs detection and voluntary treatment enrolment are less effective for minorities in Denmark. Further studies should investigate the pathways to care across population groups to inform interventions that address disparities.

Incidence of non-affective psychotic disorders in refugees and peers growing up in Denmark and Sweden: a registry linkage study

PURPOSE

Higher rates of non-affective psychotic disorders (NAPD) in minority groups have been reported in many countries. However, few studies have explored how rates differ between refugees and other minority groups and none with an international comparative angle. A comparative perspective makes it possible to relate group differences to aspects national context that underpin the social determinants of disease.

METHODS

We compared the incidence of treated NAPD among youth born in or who immigrated to Denmark/Sweden before turning 18. Youth aged 18-35 during 2006-2018 were included (NDenmark/NSweden = 1,606,423/2,614,721) and were followed until first NAPD treatment (cases [Denmark/Sweden] = 12,193/9,641), 36th birthday, emigration or death. Incidence rates (IR) and ratios (IRR) comparing refugees, non-refugee migrants, descendants of non-refugee migrants and majority youth were obtained through Poisson regression on data aggregated by country, sex and age, contrasted by sex and country. Complementary analyses on individual-level data adjusting for further socio-demographic factors were conducted in each country separately.

RESULTS

Incidence rates were higher in all groups compared with the majority group (IRRrange = 1.4-2.9, 95% CI[min, max] = 1.2-3.1). Relative differences between the three minority groups were smaller (IRRrange = 0.7-1.0, 95% CI[min, max] = 0.5-1.2). Although incidence rates were higher in Denmark than Sweden, relative group differences were similar.

CONCLUSION

Exposures shared between young refugees and other minority groups growing up in Denmark and Sweden may be especially important for their excess risk of NAPD. Further studies should investigate the mechanisms behind the elevated rates in minority groups with special paid attention to factors such as discrimination, social exclusion and acculturation stress.

Exploring causal mechanisms of psychosis risk

Robust epidemiological evidence of risk and protective factors for psychosis is essential to inform preventive interventions. Previous evidence syntheses have classified these risk and protective factors according to their strength of association with psychosis. In this critical review we appraise the distinct and overlapping mechanisms of 25 key environmental risk factors for psychosis, and link these to mechanistic pathways that may contribute to neurochemical alterations hypothesised to underlie psychotic symptoms. We then discuss the implications of our findings for future research, specifically considering interactions between factors, exploring universal and subgroup-specific factors, improving understanding of temporality and risk dynamics, standardising operationalisation and measurement of risk and protective factors, and developing preventive interventions targeting risk and protective factors.

The association between neighborhood-level social fragmentation and distressing psychotic-like experiences in early adolescence: the moderating role of close friends

BACKGROUND

Early exposure to neighborhood social fragmentation has been shown to be associated with schizophrenia. The impact of social fragmentation and friendships on distressing psychotic-like experiences (PLE) remains unknown. We investigate the relationships between neighborhood social fragmentation, number of friends, and distressing PLE among early adolescents.

METHODS

Data were collected from the Adolescent Brain Cognitive Development Study. Generalized linear mixed models tested associations between social fragmentation and distressing PLE, as well as the moderating role of the number of total and close friends.

RESULTS

Participants included 11 133 adolescents aged 9 to 10, with 52.3% being males. Greater neighborhood social fragmentation was associated with higher levels of distressing PLE (adjusted β = 0.05; 95% CI: 0.01-0.09). The number of close but not total friends significantly interacted with social fragmentation to predict distressing PLE (adjusted β = -0.02; 95% CI: -0.04 to <-0.01). Among those with fewer close friends, the association between neighborhood social fragmentation and distressing PLE was significant (adjusted β = 0.07; 95% CI: 0.03-0.11). However, among those with more close friends, the association was non-significant (adjusted β = 0.03; 95% CI: -0.01 to 0.07).

CONCLUSIONS

Greater neighborhood social fragmentation is associated with higher levels of distressing PLE, particularly among those with fewer close friends. Further research is needed to disentangle aspects of the interaction between neighborhood characteristics and the quality of social interactions that may contribute to psychosis, which would have implications for developing effective interventions at the individual and community levels.

Factors associated with the psychosis continuum among homeless people: Comparison between natives and migrants in the SAMENTA study

Background

In the last decades, there has been a documented increase in the proportion of migrants among homeless people in Europe. While homelessness is associated with psychosis, little is known about the factors associated with psychosis among migrants in this context.

Methods

Our study analyzed data collected in the SAMENTA cross-sectional survey conducted among 859 adult French-speaking homeless people living in the Greater Paris area. We analyzed the prevalence of psychosis and psychotic-like experiences (PLE) and associated factors by migrant status, using bivariate analysis and multivariable logistic regression models.

Results

Our sample comprised 280 natives and 559 migrants in France. Psychosis was significantly more prevalent among natives (21.6 %) than among migrants (7.5 %) (p = 0.003). The total prevalence of PLE was 30.8% (95 % CI: 24.3 - 38.2), and not statistically different between groups (p = 0.215) or sex (p = 0.528). Adverse events over the past year were associated with the increased odds of psychosis in both groups and with PLE among migrants. Sexual abuse during childhood was associated with both outcomes among natives. Among migrants, exposure to war or life-threatening events increased the odds of psychosis and PLE. Increased odds of psychosis were found among migrants who had been living in France for more than 10 years (OR = 3.34, 95 % CI: 1.41-7.93, p = 0.007).

Conclusion

Differences were found in the factors associated with the psychosis continuum by migrant status, they highlight the impact of experiences related to migration. Prospective studies are needed to better understand these underlying pathways.

Prevalence of multimorbidity in people with and without severe mental illness: a systematic review and meta-analysis

BACKGROUND

People with severe mental illness, such as schizophrenia-spectrum disorder and bipolar disorder, face poorer health outcomes from multiple chronic illnesses. Physical multimorbidity, the coexistence of two or more chronic physical conditions, and psychiatric multimorbidity, the coexistence of three or more psychiatric disorders, are both emerging concepts useful in conceptualising disease burden. However, the prevalence of physical and psychiatric multimorbidity in this cohort is unknown. This study aimed to estimate the absolute prevalence of both physical and psychiatric multimorbidity in people with severe mental illness, and also compare the odds of physical multimorbidity prevalence against people without severe mental illness.

METHODS

We searched CINAHL, EMBASE, PubMed, and PsycINFO from inception until Feb 15, 2024, for observational studies that measured multimorbidity prevalence. To be included, studies had to have an observational study design, be conducted in an adult population (mean age ≥18 years) diagnosed with either schizophrenia-spectrum disorder or bipolar disorder, and include a measurement of occurrence of either physical multimorbidity (≥2 physical health conditions) or psychiatric multimorbidity (≥3 psychiatric conditions total, including the severe mental illness). From control studies, a random-effects meta-analysis compared odds of physical multimorbidity between people with and without severe mental illness. Absolute prevalence of physical and psychiatric multimorbidity in people with severe mental illness was also calculated. Sensitivity and meta-regression analyses tested an array of demographic, diagnostic, and methodological variables.

FINDINGS

From 11 144 citations we included 82 observational studies featuring 1 623 773 individuals with severe mental illness (specifically schizophrenia-spectrum disorder or bipolar disorder), of which 21 studies featured 13 235 882 control individuals without severe mental illness (descriptive data for the entire pooled cohorts were not available for numbers of males and females, age, and ethnicity). This study did not feature involvement of people with lived experience. The odds ratio (OR) of physical multimorbidity between people with and without severe mental illness was 2·40 (95% CI 1·57-3·65, k=11, p=0·0009). This ratio was higher in younger severe mental illness populations (mean age ≤40 years, OR 3·99, 95% CI 1·43-11·10) compared with older populations (mean age >40 years, OR 1·55, 95% CI 0·96-2·51; subgroup differences p=0·0013). For absolute prevalence, 25% of those with severe mental illness have physical multimorbidity (95% CI 0·19-0·32, k=29) and 14% have psychiatric multimorbidity (95% CI 0·08-0·23, k=21).

INTERPRETATION

This is the first meta-analysis to estimate physical alongside psychiatric multimorbidity prevalence, showing that these are common in people with schizophrenia-spectrum disorder and bipolar disorder. The greater burden of physical multimorbidity in people with severe mental illness compared with those without is higher for younger cohorts, reflecting a need for earlier intervention. Our findings speak to the utility of multimorbidity for characterising the disease burden associated with severe mental illness, and the importance of facilitating integrated physical and mental health care.

Climate change and mental health: Position paper of the European Psychiatric Association

BACKGROUND

Climate change is one of the greatest threats to health that societies face and can adversely affect mental health. Given the current lack of a European consensus paper on the interplay between climate change and mental health, we signal a need for a pan-European position paper about this topic, written by stakeholders working in mental health care.

METHODS

On behalf of the European Psychiatric Association (EPA), we give recommendations to make mental health care, research, and education more sustainable based on a narrative review of the literature.

RESULTS

Examples of sustainable mental healthcare comprise preventive strategies, interdisciplinary collaborations, evidence-based patient care, addressing social determinants of mental health, maintaining health services during extreme weather events, optimising use of resources, and sustainable facility management. In mental health research, sustainable strategies include investigating the impact of climate change on mental health, promoting research on climate change interventions, strengthening the evidence base for mental health-care recommendations, evaluating the allocation of research funding, and establishing evidence-based definitions and clinical approaches for emerging issues such as 'eco-distress'. Regarding mental health education, planetary health, which refers to human health and how it is intertwined with ecosystems, may be integrated into educational courses.

CONCLUSIONS

The EPA is committed to combat climate change as the latter poses a threat to the future of mental health care. The current EPA position paper on climate change and mental health may be of interest to a diverse readership of stakeholders, including clinicians, researchers, educators, patients, and policymakers.

Refugee status and the incidence of affective psychotic disorders and non-psychotic bipolar disorder: A register-based cohort study of 1.3m people in Sweden

BACKGROUND

Refugees are at increased risk of non-affective psychotic disorders, but it is unclear whether this extends to affective psychotic disorders [APD] or non-psychotic bipolar disorder [NPB].

METHODS

We conducted a nationwide cohort study in Sweden of all refugees, non-refugee migrants and the Swedish-born population, born 1 Jan 1984-31 Dec 2016. We followed participants from age 14 years until first ICD-10 diagnosis of APD or NPB. We fitted Cox proportional hazards models to estimate hazard ratios [HR] and 95 % confidence intervals [95%CI], adjusted for age, sex and family income. Models were additionally stratified by region-of-origin.

RESULTS

We followed 1.3 million people for 15.1 million person-years, including 2428 new APD cases (rate: 16.0 per 100,000 person-years; 95%CI: 15.4-16.7) and 9425 NPB cases (rate: 63.8; 95%CI: 62.6-65.1). Rates of APD were higher in refugee (HRadjusted: 2.07; 95%CI: 1.55-2.78) and non-refugee migrants (HRadjusted: 1.40; 95%CI: 1.16-1.68), but lower for NPBs for refugee (HRadjusted: 0.24; 95%CI: 0.16-0.38) and non-refugee migrants (HRadjusted: 0.34; 95%CI: 0.28-0.41), compared with the Swedish-born. APD rates were elevated for both migrant groups from Asia and sub-Saharan Africa, but not other regions. Migrant groups from all regions-of-origin experienced lower rates of NPB.

LIMITATIONS

Income may have been on the causal pathway making adjustment inappropriate.

CONCLUSIONS

Refugees experience elevated rates of APD compared with Swedish-born and non-refugee migrants, but lower rates of NPB. This specificity of excess risk warrants clinical and public health investment in appropriate psychosis care for these vulnerable populations.

Moving Forward in Mental Health Care for Refugee, Asylum-Seeking, and Undocumented Children: Social Determinants, Phased Approach to Care, and Advocacy

Given the current political and climate crisis, the number of forcedly displaced individuals continues to rise, posing new challenges to host societies aiming to support and respond to the needs of those fleeing war or persecution. In this article, we turn our attention to current and historical sociopolitical contexts influencing the mental health of forcedly displaced children (ie, refugee, asylum-seeking, and undocumented) during their resettlement in high-income countries, proposing timely ways to respond to evolving needs and recommendations to redress ubiquitous structural inequities that act as barriers to education and care for the children, youth, and families seeking sanctuary.

Mapping the evidence on psychosocial interventions for migrant populations: Descriptive analysis of a living database of randomized studies

Migrant mental health is a pressing public health issue with wide-ranging implications. Many randomized controlled trials (RCTs) have been conducted in this population to assess the effects of psychosocial interventions. However, the available evidence is characterized by controversy and fragmentation, with studies focusing on different migrant populations, interventions, outcomes, delivery modalities and settings. Aiming to promote systematic reviews of the effectiveness of psychosocial interventions in different migrant groups, we have developed a living database of existing RCTs. The development of the database provides an opportunity to map the existing RCT evidence in this population. A total of 135 studies involving 24,859 participants were included in the living database. The distribution of studies by year of publication aligns with the increasing global migrant population in recent years. Most studies focus primarily on adult participants, with a limited representation of children and adolescents, and a prevalence of female participants, which is consistent with epidemiological data, except for older adults, who are underrepresented in research. Studies predominantly focus on refugees and asylum seekers, likely due to their elevated risk of mental health issues, despite the substantial presence of economic migrants worldwide. While studies mainly involve migrants from the Middle East and East Asia, epidemiological data suggest a broader geographic representation, with migrants coming from Eastern Europe, Latin America and South Asia. The present descriptive analysis of RCTs on mental health and psychosocial interventions for migrant populations provides valuable insights into the existing research landscape. It should be used to inform future research efforts, ensuring that studies are more representative of the global migrant population and more responsive to the mental health needs of migrants in different contexts.

Psychotic and Somatic Symptoms Are Frequent in Refugees With Posttraumatic Stress Disorder: A Narrative Review

OBJECTIVE

In 2021, 89.3 million refugees were vulnerable to posttraumatic stress disorder (PTSD) after exposure to multiple and repeated traumatic experiences. The recent war in Ukraine provoked 7 million refugees to flee their homes. Specific clinical presentations of PTSD in refugee populations may not be familiar to most physicians. The goal of this review is to describe the diagnosis and specific clinical features of PTSD in refugees.

METHODS

This narrative review of 263 articles explores 3 PTSD diagnoses that are frequently described in refugee populations and that have been observed in our clinical practices: complex PTSD, PTSD with psychotic symptoms, and PTSD with somatic symptoms.

RESULTS

While complex PTSD does not seem to be related to individuals' culture and origin, the other 2 diagnoses have been specifically described in refugee populations. PTSD with somatic manifestations appears to be the most frequently described and commonly acknowledged form in refugee populations, whereas PTSD with psychotic symptoms remains more controversial due to its clinical variability and association with comorbid disorders.

CONCLUSIONS

The difficulty of identifying PTSD with psychotic symptoms and PTSD with somatic symptoms in refugee populations may lead to misdiagnosis and explain the moderate effectiveness of care delivered to these populations. Appropriate diagnosis is essential to provide optimal psychiatric care to refugee populations.

Risk of unemployment and work disability among refugee and non-refugee migrants with incident psychotic disorders in Sweden and Denmark

BACKGROUND

Unemployment and work disability are common among individuals with non-affective psychotic disorders (NAPDs) but it is unknown whether rates differ among migrants and native-born individuals. The present study aimed to compare the risk of these outcomes during the first 5 years of illness in non-refugee migrants, refugees and native-born individuals with NAPDs in Sweden and Denmark-two countries with different immigration policies and models of early psychosis care.

METHODS

Using national registers, we identified all individuals aged 18-35 years in Sweden and Denmark who received an incident NAPD diagnosis between 2006 and 2013 (N = 6750 and 8320, respectively). Cohorts were followed for 5 years to determine the days of unemployment and sickness absence (analyzed using zero-inflated negative binomial models) and the time to receipt of disability pension (analyzed using complementary log-log models).

RESULTS

Relative to their native-born peers, refugees and non-refugee migrants in Sweden and non-refugee migrants in Denmark were significantly less likely to have zero unemployment days (OR range: 0.54-0.72) and all migrant groups experienced more unemployment days (IRR range: 1.26-1.37). Results were largely unchanged after adjustment for sociodemographic and clinical factors. In the adjusted model, both Swedish migrant groups and refugees in Denmark were more likely to experience zero sickness absence days than native-born individuals (OR range: 1.48-1.56). Only refugees in Denmark were at greater risk of disability pension.

CONCLUSIONS

Non-refugee migrants and refugees with NAPDs in both Sweden and Denmark are particularly vulnerable to experiencing unemployment. Targeted interventions may help to reduce these disparities and promote long-term work ability among migrant groups.

Treated incidence of first episode psychosis in Sinop, Turkey: results of a 4-year admission-based study - SINOPsy

BACKGROUND

The incidence of psychotic disorders varies in different geographic areas. As there has been no report from Turkey, this study aimed to provide the treated incidence rate of first-episode psychosis (FEP) in a defined area.

METHODS

All individuals, aged 15-64 years, presenting with FEP (ICD-10 F20-29, F30-33) to mental health services in a defined catchment-area in Sinop which is located in the Black Sea region of the northern Turkey were recorded over a 4-year period (2009 to 2012). Incidence rates of psychotic disorders and their 95% confidence intervals (CIs) were estimated. Poisson regression was applied to estimate the differences in incidence rate ratio (IRR) by age, sex, and urbanicity.

RESULTS

One hundred and fifteen FEP participants were identified during the 4 years. Crude incidence rates of all psychoses, schizophrenia, other psychotic disorders, and affective psychotic disorders were respectively 38.5 (95% CI 27.1-49.9), 10.7 (95% CI 6.6-14.8), 10.0 (95% CI 5.7-14.3) and 17.7 (95% CI 11.3-24.2) per 100 000 person-years. After age-sex standardisation the rates increased slightly. There were no gender differences in the incidence rates. IRR of any psychotic disorder was highest in the youngest age group (15-24 years) compared to the oldest age group (55-64 years), 7.9 (95% CI 2.8-30.5). In contrast with previous studies, the incidence rate of any psychotic disorder was not significantly increased in urban areas compared with rural areas.

CONCLUSIONS

The current study, the first of its kind from Turkey, indicates that the risk of schizophrenia and other psychotic disorders in a lowly urbanised area of Turkey is comparable to those reported in Western European cities.

The social determinants of mental health and disorder: evidence, prevention and recommendations

People exposed to more unfavourable social circumstances are more vulnerable to poor mental health over their life course, in ways that are often determined by structural factors which generate and perpetuate intergenerational cycles of disadvantage and poor health. Addressing these challenges is an imperative matter of social justice. In this paper we provide a roadmap to address the social determinants that cause mental ill health. Relying as far as possible on high-quality evidence, we first map out the literature that supports a causal link between social determinants and later mental health outcomes. Given the breadth of this topic, we focus on the most pervasive social determinants across the life course, and those that are common across major mental disorders. We draw primarily on the available evidence from the Global North, acknowledging that other global contexts will face both similar and unique sets of social determinants that will require equitable attention. Much of our evidence focuses on mental health in groups who are marginalized, and thus often exposed to a multitude of intersecting social risk factors. These groups include refugees, asylum seekers and displaced persons, as well as ethnoracial minoritized groups; lesbian, gay, bisexual, transgender and queer (LGBTQ+) groups; and those living in poverty. We then introduce a preventive framework for conceptualizing the link between social determinants and mental health and disorder, which can guide much needed primary prevention strategies capable of reducing inequalities and improving population mental health. Following this, we provide a review of the evidence concerning candidate preventive strategies to intervene on social determinants of mental health. These interventions fall broadly within the scope of universal, selected and indicated primary prevention strategies, but we also briefly review important secondary and tertiary strategies to promote recovery in those with existing mental disorders. Finally, we provide seven key recommendations, framed around social justice, which constitute a roadmap for action in research, policy and public health. Adoption of these recommendations would provide an opportunity to advance efforts to intervene on modifiable social determinants that affect population mental health.

How much schizophrenia do famines cause?

Since the 1970s, famines have been widely invoked as natural experiments in research into the long-term impact of foetal exposure to nutritional shocks. That research has produced compelling evidence for a robust link between foetal exposure and the odds of developing schizophrenia. However, the implications of that research for the human cost of famines in the longer run have not been investigated. We address the connection between foetal origins and schizophrenia with that question in mind. The impact turns out to be very modest-much less than one per cent of the associated famine death tolls-across a selection of case studies.

Linguistic findings in persons with schizophrenia-a review of the current literature

INTRODUCTION

Alterations of verbalized thought occur frequently in psychotic disorders. We characterize linguistic findings in individuals with schizophrenia based on the current literature, including findings relevant for differential and early diagnosis.

METHODS

Review of literature published via PubMed search between January 2010 and May 2022.

RESULTS

A total of 143 articles were included. In persons with schizophrenia, language-related alterations can occur at all linguistic levels. Differentiating from findings in persons with affective disorders, typical symptoms in those with schizophrenia mainly include so-called "poverty of speech," reduced word and sentence production, impaired processing of complex syntax, pragmatic language deficits as well as reduced semantic verbal fluency. At the at-risk state, "poverty of content," pragmatic difficulties and reduced verbal fluency could be of predictive value.

DISCUSSION

The current results support multilevel alterations of the language system in persons with schizophrenia. Creative expressions of psychotic experiences are frequently found but are not in the focus of this review. Clinical examinations of linguistic alterations can support differential diagnostics and early detection. Computational methods (Natural Language Processing) may improve the precision of corresponding diagnostics. The relations between language-related and other symptoms can improve diagnostics.

Comparison of Hospitalization for Nonaffective Psychotic Disorders Among Refugee, Migrant, and Native-Born Adults in Sweden and Denmark

Importance

Determining whether migrants with nonaffective psychotic disorders (NAPDs) experience poorer outcomes after illness onset is essential to ensure adequate health care provision to these disadvantaged populations.

Objective

To compare cumulative hospital days for NAPDs during the first 5 years of illness among refugee, nonrefugee, and second-generation migrants and their Swedish and Danish peers.

Design, Setting, and Participants

This was a prospective cohort study of individuals treated for incident NAPDs in inpatient or outpatient settings between January 1, 2006, and December 31, 2013, and followed up for 5 years. This population-based study used Swedish and Danish national registries. Included participants were individuals in Sweden and Denmark, aged 18 to 35 years, treated for incident NAPDs. Data analyses were conducted from November 2022 to August 2023.

Exposures

Population group (determined according to residency in either country, not both countries), categorized as refugee (migrants whose residence in Sweden or Denmark was registered as refugee status or family reunification with a refugee), nonrefugee (all other individuals born outside Sweden and Denmark), second generation (individuals born in Sweden or Denmark with at least 1 parent born abroad), or native born (individuals born in Sweden or Denmark with both parents born in these countries).

Main Outcome and Measures

Total hospital days for NAPDs during the first 5 years of illness, analyzed using a hurdle model. Among those ever admitted, total number of admissions and mean admission length were examined.

Results

In total, 7733 individuals in Sweden (mean [SD] age, 26.0 [5.1] years; 4919 male [63.6%]) and 8747 in Denmark (mean [SD] age 24.8 [5.0] years; 5324 male [60.9%]) were followed up for 5 years or until death or emigration. After adjusting for a range of sociodemographic and clinical factors, the odds of experiencing any hospital days for NAPD were significantly higher among migrant groups compared with their native-born peers (Sweden: second generation, odds ratio [OR], 1.17; 95% CI, 1.03-1.33; P = .01; nonrefugee migrant, OR, 1.45; 95% CI, 1.21-1.73; P < .001; refugee, OR, 1.25; 95% CI, 1.06-1.47; P = .009; Denmark: second generation, OR, 1.21; 95% CI, 1.05-1.40; P = .01; nonrefugee migrant, OR, 1.33; 95% CI, 1.14-1.55; P < .001). These odds were highest among nonrefugee (Sweden: OR, 2.53; 95% CI, 1.59-4.03; P < .001; Denmark: OR, 2.61; 95% CI, 1.70-4.01; P < .001) and refugee (Sweden: OR, 1.96; 95% CI, 1.43-2.69; P < .001; Denmark: OR, 2.14; 95% CI, 1.42-3.21; P < .001) migrants from Africa and those who had arrived within 3 to 5 years (Sweden: nonrefugee migrants, OR, 1.93; 95% CI, 1.26-2.95; P = .002; refugees, OR, 2.38; 95% CI, 1.46-3.88; P < .001; Denmark: nonrefugee migrants, OR, 1.66; 95% CI, 0.96-2.85; P = .07; refugees, OR, 3.40; 95% CI, 1.13-10.17; P = .03). Among those ever hospitalized, refugees in both countries (Sweden, incidence rate ratio [IRR], 1.30; 95% CI, 1.12-1.51; P < .001; Denmark, IRR, 1.47; 95% CI, 1.24-1.75; P < .001) and second-generation migrants in Denmark (IRR, 1.22; 95% CI, 1.07-1.39; P = .003) experienced more days hospitalized for NAPDs than native-born individuals.

Conclusions and Relevance

In this prospective cohort study of individuals with NAPDs, results suggest that refugee, nonrefugee, and second-generation migrants experience more days hospitalized for these disorders than their native-born peers. Patterns were consistent across 2 countries with different models of psychosis care and immigration and integration policies.

The prevalence of non-affective psychosis in refugee populations: A systematic review

BACKGROUND

As we face the largest refugee crisis since World War Two, research is increasingly examining the impact of forced displacement. The risk of non-affective psychosis in refugees is evidenced to be significantly greater than non-refugees, and the role of pre-, peri- and post-migratory trauma and dissociation is increasingly implicated.

AIMS

To determine the prevalence of non-affective psychosis in refugee populations.

METHOD

PRISMA guidelines were followed. Three key databases (PubMed, PsychINFO and Web of Science), Google scholar and study references were searched. The full-text of 62 studies were screened and 23 studies were eligible for inclusion. A narrative synthesis was undertaken and the Quality Assessment Tool for Quantitative Studies was used to assess methodological quality. (PROSPERO registration CRD42019152170).

RESULTS

The results were widely heterogeneous. The combined weighted average prevalence of non-affective psychosis in refugee populations was 0.9 %. Psychosis prevalence for individual psychotic symptoms was 28.4 %; 0.5 % for schizophrenia; 1.0 % for psychosis; 0.6 % for mixed psychotic disorders and 2.9 % for psychotic episodes.

CONCLUSIONS

Variations in examined populations, diagnostic and prevalence classifications, and study designs and methodologies likely contributed to heterogeneity across the data. The findings highlight a greater need to provide more specialist mental health services and trauma-focused interventions, as well as transculturally sensitive assessment and treatment to address refugee vulnerability to psychosis. Future research should examine psychosis prevalence longitudinally and in refugees-only, address methodological bias and further examine the role of trauma and dissociation in refugee psychosis prevalence.

Racism and psychosis: an umbrella review and qualitative analysis of the mental health consequences of racism

Black people and People of Color are disproportionately affected by racism and show increased rates of psychosis. To examine whether racialized migrant groups are particularly exposed to racism and therefore have higher risks for psychosis, this paper (1) systematically assesses rates of psychosis among racialized migrant groups concerning the country of origin, and (2) analyzes interviews regarding the association of racism experiences with psychosis-related symptoms in racialized Black people and People of Color populations in Germany. We present an umbrella review of meta-analyses that report the incidence of positive symptoms (e.g., hallucinations and delusions) and negative symptoms (e.g., apathy and incoherent speech) of diagnosed schizophrenia, other non-affective psychotic disorders (e.g., schizoaffective disorder) or first-episode psychosis among migrants by country of origin. We also report 20 interviews with first- and second-generation migrants racialized as Black and of Color in Germany to capture and classify their experiences of racism as well as racism-associated mental health challenges. In the umbrella review, psychosis risk was greatest when migration occurred from developing countries. Effect size estimates were even larger among Caribbean and African migrants. In the qualitative study, the application of the constant comparative method yielded four subordinate themes that form a subclinical psychosis symptomatology profile related to experiences of racism: (1) a sense of differentness, (2) negative self-awareness, (3) paranoid ideation regarding general persecution, and (4) self-questioning and self-esteem instability. We here provide converging evidence from a quantitative and qualitative analysis that the risk of poor mental health and psychotic experiences is related to racism associated with minority status and migration.

Are migrants diagnosed with a trauma-related disorder at risk of premature mortality? A register-based cohort study in Denmark

Background

Mental illness is common among refugees displaced by conflict and war. While evidence points to the relatively good health in terms of longevity of migrants resettled in the destination country, less is known about the mortality of the most vulnerable migrants with a trauma-related diagnosis alone and those with an additional comorbid psychotic disorder. This study aimed to provide an overview of the number and mortality of foreign-born individuals diagnosed with Post-Traumatic Stress Disorder or Enduring Personality Change after a Catastrophic Event (PTSD/EPCACE), a psychotic disorder or both.

Methods

A nationwide register-based cohort study, including residents in Denmark, followed from 1 January 1995 to 31 December 2016. The exposure was PTSD/EPCACE and psychotic disorders as well as region of origin. Relative all-cause mortality was estimated using Cox proportional hazards regression models and calculated for migrants with one or both groups of disorders compared to those from the same region without the disorder.

Results

During the study period, 6,580,000 individuals (50.4% women) were included in the cohort. Of these 1,249,654 (50.5% women) died during follow-up. For men and women from the former Yugoslavia, the Middle East and Northern Africa, a PTSD/EPCACE diagnosis alone or with comorbid psychotic disorder was not associated with increased mortality after adjusting for region of origin. A psychotic disorder alone, however, was associated with an increased mortality rate.

Conclusion

Despite the severity of many refugees' traumatic experiences, a diagnosis of a trauma-related psychiatric disorder did not appear to increase the mortality rates.

Review of Major Social Determinants of Health in Schizophrenia-Spectrum Psychotic Disorders: I. Clinical Outcomes

BACKGROUND

Social determinants of health (SDoHs) are receiving growing attention and are particularly relevant to persons with schizophrenia-spectrum psychotic disorders (SSPDs), considering their heightened risk of comorbidities, cognitive and functional decline, and early mortality. Yet, we did not find any comprehensive review of multiple SDoHs in SSPD.

STUDY DESIGN

We conducted a scoping review of meta-analyses and systematic reviews of nine major SDoHs in SSPD.

STUDY RESULTS

Childhood abuse, parental psychopathology, parental communication problems, bullying, and urban settings with lower socioeconomic status were major risk factors for the greater incidence of SSPD and/or worse health. Social network size was inversely associated with overall psychopathology and negative symptoms. Experiences of racial/ethnic discrimination correlated with the prevalence of psychotic symptoms and experiences. Compared to native populations, the risk of psychosis was higher in immigrants, refugees, and asylees. Social fragmentation was associated with an increased prevalence of schizophrenia. Homeless populations had a 30-fold higher prevalence of schizophrenia than the general population. Seriously mentally ill people were 2.7 times more likely to report food insecurity than controls. The prevalence of non-affective psychosis in prisoners was 2.0%-6.5%, compared to 0.3% in the general population. Certain potentially positive factors like family and community resilience remain poorly studied.

CONCLUSIONS

SDoHs are associated with higher rates of and worse outcomes in SSPD. Well-designed longitudinal studies are needed to understand SDoHs' contribution to health in persons with SSPD, to develop interventions, and to implement changes in clinical care and public health policies that would reduce adverse health impacts of SDoHs. Positive SDoHs deserve greater attention.

Migrant status, clinical symptoms and functional outcome in youth at clinical high risk for psychosis: findings from the NAPLS-3 study

PURPOSE

Migrant status is a known risk factor for psychosis, but the underlying causes of this vulnerability are poorly understood. Recently, studies have begun to explore whether migrant status predicts transition to psychosis in individuals at clinical high risk (CHR) for psychosis. Results, however, have been inconclusive. The present study assessed the impact of migrant status on clinical symptoms and functional outcome in individuals at CHR for psychosis who took part in the NAPLS-3 study.

METHODS

Participants' migrant status was classified as native-born, first-generation, or second-generation migrant. Clinical symptoms were assessed using the Structured Interview for Psychosis-Risk Syndromes (SIPS); functional outcome was measured using the Global Functioning Scales:Social and Role (GF:S; GF:R). Assessments were conducted at baseline, 12-months, 18-months, and 24-months follow-up. Generalized linear mixed models for repeated measures were used to examine changes over time and differences between groups.

RESULTS

The overall sample included 710 individuals at CHR for psychosis (54.2% males; Age: M = 18.19; SD = 4.04). A mixed model analysis was conducted, and no significant differences between groups in symptoms or functioning were observed at any time point. Over time, significant improvement in symptoms and functioning was observed within each group. Transition rates did not differ across groups.

CONCLUSION

We discuss potential factors that might explain the lack of group differences. Overall, migrants are a heterogeneous population. Discerning the impact of migration from that of neighborhood ethnic density, social disadvantage or socio-economic status of different ethnic groups could help better understand vulnerability and resilience to psychosis.

Early childhood adversity and non-affective psychosis: a study of refugees and international adoptees in Sweden

BACKGROUND

Previous Scandinavian studies have shown increased levels of psychiatric morbidity in young refugees and international adoptees with an origin outside Europe. This study investigated their risk of non-affective psychotic disorders (NAPD) and whether this risk is influenced by early childhood adversity, operationalised as age at adoption/residency, and/or gender.

METHODS

Register study in Swedish national cohorts born 1972-1990 including 21 615 non-European international adoptees, 42 732 non-European refugees that settled in Sweden at age 0-14 years and 1 610 233 Swedish born. The study population was followed from age 18 to year 2016 for hospitalisations with a discharge diagnosis of NAPD. Hazard ratios (HRs) were calculated in gender stratified Cox regression models, adjusted for household income at age 17.

RESULTS

The adjusted risks of NAPD were 2.33 [95% confidence interval (CI) 2.07-2.63] for the international adoptees and 1.92 (1.76-2.09) for the former child refugees, relative to the Swedish-born population. For the international adoptees there was a stepwise gradient for NAPD by age of adoption from adjusted HR 1.66 (1.29-2.03) when adopted during the first year of life to adjusted HR 4.56 (3.22-6.46) when adopted at ages 5-14 years, with a similar risk pattern in women and men. Age at residency did not influence the risk of NAPD in the refugees, but their male to female risk ratio was higher than in Swedish-born and the adoptees.

CONCLUSION

The risk pattern in the international adoptees gives support to a link between early childhood adversity and NAPD. Male gender increased the risk of NAPD more among the refugees.

The refugee and asylum seeker mental health treatment screener (RAS-MT-screener): Feasibility and psychometric properties of a questionnaire detecting refugees' and asylum seekers' need and urgency for mental health treatment

OBJECTIVE

Refugees and asylum seekers are highly vulnerable to the development of mental health problems, yet oftentimes their need is underestimated. We aimed to develop a culturally sensitive screening tool for primary care settings assessing the urgency and need for mental health treatment to close this gap.

METHOD

Items for the screening tool were selected out of an item pool generated by a group of clinical experts based on the data obtained from n = 307 asylum seekers in a refugee state registration and reception center in Germany. Out of these, n = 111 attended a psychosocial walk-in clinic, and clinicians' ratings of urgency and need for mental health treatment were added.

RESULTS

The resulting questionnaire comprised 8 items assessing urgency and 13 items assessing need for mental health treatment. Sensitivity was =0.74 and specificity =0.70. Participants of clinical and non-clinical samples differ highly significantly (p < .001). Cross-cultural validity was shown by comparing measurement invariance for different countries of origin.

CONCLUSION

The RAS-MT-Screener is a clinically and cross-culturally valid screening tool in primary care settings for the urgency and need for mental health treatment with acceptable psychometric properties. Future research on its external and construct validity is warranted.

[Climate change and mental health. Position paper of a task force of the DGPPN]

Climate change and the resulting higher frequency of extreme weather events have a direct negative impact on mental health. Natural disasters are particularly associated with an increase in the prevalence of depression, anxiety and posttraumatic stress disorder. Indirect consequences of climate change, such as food shortages, economic crises, violent conflicts and forced migration, additionally represent severe psychological risk and stress factors. Climate anxiety and solastalgia, the distress induced by environmental change, are new psychological syndromes in the face of the existential threat posed by the climate crisis. Accordingly, a sustainable psychiatry must prepare for increasing and changing demands. The principles of psychiatric treatment need to focus more on prevention to reduce the overall burden on the healthcare system. Waste of resources and CO₂ emissions in psychiatric treatment processes as well as infrastructure must be perceived and prevented. Psychiatric education, training and continuing education concepts should be expanded to include the topic of climate change in order to comprehensively inform and sensitize professionals, those affected and the public and to encourage climate-friendly and health-promoting behavior. More in-depth research is needed on the impact of climate change on mental health. The DGPPN becomes a sponsor and aims for climate neutrality by 2030 by committing to climate-friendly and energy-saving measures in the area of finance, in relation to the DGPPN congress as well as the DGPPN office.

[On the Ideological Function of a Traditional Criticism of Psychiatry in Neoliberalism]

Social isolation and discrimination play a major role in the development and maintenance of mental disorders. This could motivate a critical public to demand improved treatment facilities for persons with mental illness. Instead, the media and a critical public tend to repeat a traditional critique of psychiatry, which was articulated before psychiatry reform in the 1970s and which tends to romanticize or neglect mental illness. The replication of this traditional critique of psychiatry today has an ideological function: it reassures a neoliberal public that it is emancipated from traditional authoritarian patterns of dominance, rejects demands for increased funding of mental health treatment facilities, and emphasizes individual autonomy at the price of blaming the victims for homelessness and social impoverishment.

Challenges in health care services for refugees in Cologne, Germany: A providers' perspective using a mixed-methods approach

Since the peak of refugees arriving in Germany in 2015, existing health care structures have faced major challenges. The city of Cologne developed ad-hoc new structures to address these challenges, including a separate department for refugee medicine. We examine the processes of health care provision and perceived challenges in the health care of refugees in Cologne. We used a mixed-methods approach using 20 semi-structured interviews and analyzed descriptively a database including 353 datasets with socio-demographic, health-related and resource-related information to link with the results of qualitative data. Our qualitative data revealed several challenges in providing health care to refugees. Challenges included receiving approval of health care services and medical aids by the municipality, communication and cooperation between the actors in care of refugees, undersupplies in mental health care and addictive disorders as well as improper housing conditions for refugees with mental health issues, psychiatric disorders or elderly persons. Quantitative data confirmed the challenges in approving health care services and medical aids, but no valid statement could be made about communication and cooperation. Undersupplies for mental health issues were confirmed, the gap for treatment of addictive disorders shows a divergence within the database. Improper housing conditions for mentally ill persons were reflected, for elderly persons this did not appear in data. In conclusion, analyzing the challenges in care can stimulate necessary changes to improve health services for refugees locally, while others are beyond the control of the local authority and require legislative and political action.

Increased social identification is linked with lower depressive and anxiety symptoms among ethnic minorities and migrants: A systematic review and meta-analysis

Evidence suggests that social identities, which provide purpose and a sense of belonging to the social world, promote resilience against psychological strain and protect well-being. This is especially important in ethnic minorities, who experience exclusion and discrimination from the majority group, and in migrant populations where adverse experiences, such as prejudice, disconnection from previous identities and issues of integration into the host country, negatively impact well-being. Drawing from the social identity theory, a meta-analysis was conducted examining the influence of group memberships and sense of belonging on ethnic minority and migrant mental health (depression and anxiety). The final search on three databases (i.e., PubMed, PsycINFO, Web of Science) was conducted on August 9th, 2022, identifying 3236 citations before removing any duplicates within and between databases. Across the 74 studies that met the inclusion criteria for the meta-analysis, increased social identification (ethnic, national and other types of identification) was associated with low psychological symptoms. We found that social identification is protective against common psychological disorders but with small effect sizes for depression (r = - 0.09, CI = [- 0.12; - 0.06]) and anxiety (r = - 0.08, CI [- 0.12; - 0.03]). Results are discussed with regard to the role that social context plays on ethnic minority and migrant mental health and the importance of facilitating migrant integration with the host society after displacement.

Racial discrimination and its impact on mental health

There is evidence that racial discrimination at different levels has a major impact on mental health over the whole life span. It is related generally to poor health, with the relationship being particularly strong for mental health. All forms of structural, institutionalised, interpersonal and internalised racism as well as the cumulative impact of intersectional discrimination appear to be linked to mental health and well-being. Studies also show links between effects of racial discrimination and neurophysiology especially on the brain volume. All forms of racism need to be addressed in inter- and transdisciplinary ways in order to dismantle racial discrimination. This review provides an overview of these interconnections.

Twelve-month follow-up of a randomised clinical trial of a brief group psychological intervention for common mental disorders in Syrian refugees in Jordan

AIMS

There is increasing evidence that brief psychological interventions delivered by lay providers can reduce common mental disorders in the short-term. This study evaluates the longer-term impact of a brief, lay provider delivered group psychological intervention (Group Problem Management Plus; gPM+) on the mental health of refugees and their children's mental health.

METHODS

This single-blind, parallel, controlled trial randomised 410 adult Syrians in Azraq Refugee Camp in Jordan who screened positive for distress and impaired functioning to either five sessions of gPM+ or enhanced usual care (EUC). Primary outcomes were scores on the Hopkins Symptom Checklist-25 (HSCL-25; depression and anxiety scales) assessed at baseline, 6 weeks, 3 months and 12 months Secondary outcomes included disability, posttraumatic stress, personally identified problems, prolonged grief, prodromal psychotic symptoms, parenting behaviour and children's mental health.

RESULTS

Between 15 October 2019 and 2 March 2020, 204 participants were assigned to gPM + and 206 to EUC, and 307 (74.9%) were retained at 12 months. Intent-to-treat analyses indicated that although participants in gPM + had greater reductions in depression at 3 months, at 12 months there were no significant differences between treatment arms on depression (mean difference -0.9, 95% CI -3.2 to 1.3; p = 0.39) or anxiety (mean difference -1.7, 95% CI -4.8 to -1.3; p = 0.06). There were no significant differences between conditions for secondary outcomes except that participants in gPM + had greater increases in positive parenting.

CONCLUSIONS

The short-term benefits of a brief, psychological programme delivered by lay providers may not be sustained over longer time periods, and there is a need for sustainable programmes that can prolong benefits gained through gPM + .

Migration history and risk of psychosis: results from the multinational EU-GEI study

BACKGROUND

Psychosis rates are higher among some migrant groups. We hypothesized that psychosis in migrants is associated with cumulative social disadvantage during different phases of migration.

METHODS

We used data from the EUropean Network of National Schizophrenia Networks studying Gene-Environment Interactions (EU-GEI) case-control study. We defined a set of three indicators of social disadvantage for each phase: pre-migration, migration and post-migration. We examined whether social disadvantage in the pre- and post-migration phases, migration adversities, and mismatch between achievements and expectations differed between first-generation migrants with first-episode psychosis and healthy first-generation migrants, and tested whether this accounted for differences in odds of psychosis in multivariable logistic regression models.

RESULTS

In total, 249 cases and 219 controls were assessed. Pre-migration (OR 1.61, 95% CI 1.06-2.44, p = 0.027) and post-migration social disadvantages (OR 1.89, 95% CI 1.02-3.51, p = 0.044), along with expectations/achievements mismatch (OR 1.14, 95% CI 1.03-1.26, p = 0.014) were all significantly associated with psychosis. Migration adversities (OR 1.18, 95% CI 0.672-2.06, p = 0.568) were not significantly related to the outcome. Finally, we found a dose-response effect between the number of adversities across all phases and odds of psychosis (⩾6: OR 14.09, 95% CI 2.06-96.47, p = 0.007).

CONCLUSIONS

The cumulative effect of social disadvantages before, during and after migration was associated with increased odds of psychosis in migrants, independently of ethnicity or length of stay in the country of arrival. Public health initiatives that address the social disadvantages that many migrants face during the whole migration process and post-migration psychological support may reduce the excess of psychosis in migrants.

The effects of social isolation stress and discrimination on mental health

Social isolation and discrimination are growing public health concerns associated with poor physical and mental health. They are risk factors for increased morbidity and mortality and reduced quality of life. Despite their detrimental effects on health, there is a lack of knowledge regarding translation across the domains of experimental research, clinical studies, and real-life applications. Here, we review and synthesize evidence from basic research in animals and humans to clinical translation and interventions. Animal models indicate that social separation stress, particularly in early life, activates the hypothalamic-pituitary-adrenal axis and interacts with monoaminergic, glutamatergic, and GABAergic neurotransmitter systems, inducing long-lasting reductions in serotonin turnover and alterations in dopamine receptor sensitivity. These findings are of particular importance for human social isolation stress, as effects of social isolation stress on the same neurotransmitter systems have been implicated in addictive, psychotic, and affective disorders. Children may be particularly vulnerable due to lasting effects of social isolation and discrimination stress on the developing brain. The effects of social isolation and loneliness are pronounced in the context of social exclusion due to discrimination and racism, during widespread infectious disease related containment strategies such as quarantine, and in older persons due to sociodemographic changes. This highlights the importance of new strategies for social inclusion and outreach, including gender, culture, and socially sensitive telemedicine and digital interventions for mental health care.

Aetiological research on the health of migrants living in Germany: a systematic literature review

BACKGROUND

Germany has become an important immigration country and health services need to adopt to meet the needs of an increasingly multicultural population. For public health planning, it is essential to understand the aetiology of health problems among migrant populations. The main objective was to systematically identify, evaluate and synthesise population-based studies that investigated exposure-outcome relationships among migrant groups in Germany.

METHODS

In November 2019, we searched PubMed and LIVIVO, and updated this search in November 2020, to identify peer-reviewed publications that fulfilled our eligibility criteria: English or German language; study on disease aetiology among major migrant groups in Germany, according to the latest microcensus; publication date from inception to 01 November 2020 and observational or experimental study designs. For quality appraisal, we used the Critical Appraisal Skills Programme checklists. Outcomes under investigation were categorised according to the WHO major disease groups, and their associations with risk factors were synthesised as a heat map.

RESULTS

Out of 2407 articles retrieved, we included 68 publications with a total number of 864 518 participants. These publications reported on cross-sectional data (n=56), cohort studies (n=11) and one intervention study. The population groups most frequently studied were from the Middle East (n=28), Turkey (n=24), sub-Saharan Africa (n=24), Eastern Europe (n=15) and the former Soviet Union (n=11). The outcomes under study were population group specific. There were consistent associations of demographic and socioeconomic factors with ill health among migrants in Germany.

DISCUSSION

In this systematic review, we observed low risk of bias in two-thirds of the studies. There is an increasing body of evidence for aetiological research on migrants' health in Germany. Still, the directions of associations between a wide range of risk factors and major disease groups seem only partially understood.

Ten years of tracking mental health in refugee primary health care settings: an updated analysis of data from UNHCR's Health Information System (2009-2018)

BACKGROUND

This study examines mental, neurological, and substance use (MNS) service usage within refugee camp primary health care facilities in low- and middle-income countries (LMICs) by analyzing surveillance data from the United Nations High Commissioner for Refugees Health Information System (HIS). Such information is crucial for efforts to strengthen MNS services in primary health care settings for refugees in LMICs.

METHODS

Data on 744,036 MNS visits were collected from 175 refugee camps across 24 countries between 2009 and 2018. The HIS documented primary health care visits for seven MNS categories: epilepsy/seizures, alcohol/substance use disorders, mental retardation/intellectual disability, psychotic disorders, severe emotional disorders, medically unexplained somatic complaints, and other psychological complaints. Combined data were stratified by 2-year period, country, sex, and age group. These data were then integrated with camp population data to generate MNS service utilization rates, calculated as MNS visits per 1000 persons per month.

RESULTS

MNS service utilization rates remained broadly consistent throughout the 10-year period, with rates across all camps hovering around 2-3 visits per 1000 persons per month. The largest proportion of MNS visits were attributable to epilepsy/seizures (44.4%) and psychotic disorders (21.8%). There were wide variations in MNS service utilization rates and few consistent patterns over time at the country level. Across the 10 years, females had higher MNS service utilization rates than males, and rates were lower among children under five compared to those five and older.

CONCLUSIONS

Despite increased efforts to integrate MNS services into refugee primary health care settings over the past 10 years, there does not appear to be an increase in overall service utilization rates for MNS disorders within these settings. Healthcare service utilization rates are particularly low for common mental disorders such as depression, anxiety, post-traumatic stress disorder, and substance use. This may be related to different health-seeking behaviors for these disorders and because psychological services are often offered outside of formal health settings and consequently do not report to the HIS. Sustained and equitable investment to improve identification and holistic management of MNS disorders in refugee settings should remain a priority.

Treatment adherence to psychotropic drugs among non-Western migrants: a systematic review

BACKGROUND

Low medication adherence is a significant challenge in all medical fields and particularly in mental health treatment, where a lack of insight into one's own disease can repress the ability to adhere. In recent years, the increase in migration combined with a high prevalence of mental illnesses among migrants and the possible consequences of nonadherence, point towards the need for a focus on adherence with psychotropic drugs among migrants.

AIM

To review current literature, exploring the potential impact of being a migrant from a non-Western country living in a Western country on the level of adherence to psychotropic medication and subsequently to discuss these findings.

METHODS

A systematic review of studies investigating adherence among non-western migrants was conducted. The literature search was conducted using PubMed and Embase databases in October 2020.

RESULTS

Seven observational studies were included, all ranging from moderate to high-quality. Six out of seven studies found an association between being a non-Western migrant in a Western country and low adherence to psychotropic drugs.

CONCLUSION

Studies indicate an association between being a non-Western migrant in a Western country and low adherence to psychotropic drugs. None of the included studies investigated possible causes of the low adherence in migrants. Communication difficulties are, however, considered possible barriers to healthcare access and a contributing factor to nonadherence. There is a need for studies assessing the possible impact of interventions aiming at increasing adherence such as intercultural mediators and training of healthcare providers in cultural competencies.

Preventing the mental health consequences of war in refugee populations

The refugee experience is associated with several potentially traumatic events that increase the risk of developing mental health consequences, including worsening of subjective wellbeing and quality of life, and risk of developing mental disorders. Here we present actions that countries hosting forcibly displaced refugees may implement to decrease exposure to potentially traumatic stressors, enhance subjective wellbeing and prevent the onset of mental disorders. A first set of actions refers to the development of reception conditions aiming to decrease exposure to post-migration stressors, and a second set of actions refers to the implementation of evidence-based psychological interventions aimed at reducing stress, preventing the development of mental disorders and enhancing subjective wellbeing.

Training in cultural psychiatry: Translating research into improvements in mental health care for migrants

This special issue of Transcultural Psychiatry on training in cultural psychiatry discusses translating research into improvements in mental health care for refugees and migrants. This topic is timely because, in addition to a global increase in migration, the number of forcibly displaced people is growing rapidly due to war and conflicts. We know that migrants, particularly refugees, are at increased risk of psychiatric disorders, including psychotic disorders and post-traumatic stress. Despite this, there is evidence of major disparities in care for minorities, migrants, and refugees. The gap between needs related to mental health care for migrants, refugees, and minority groups and available services points to the need to improve accessibility and adapt systems, services, and interventions. Health professionals have a key role in ensuring the quality of care. Their capacity to cope with new challenges depends on their competence, knowledge, skills, and attitudes toward their patients' needs. Mental health professionals need training in working with cultural diversity and structural competence to understand, treat, and support migrant and refugee patients-and to respond to racial discrimination. Mental health care services need to reduce barriers to providing adequate resources, including supporting skills training for mental health professionals. Hopefully, this thematic special issue will motivate further research, discussion, and sharing of local experience and pedagogical methods in this vital field.

Comparing Risk Factors for Non-affective Psychotic Disorders With Common Mental Disorders Among Migrant Groups: A 25-Year Retrospective Cohort Study of 2 Million Migrants

BACKGROUND AND HYPOTHESIS

Although migration is a well-established risk factor for psychotic disorders, less is known about factors that modify risk within migrant groups. We sought to assess whether socio-demographic, migration-related, and post-migration factors were associated with the risk of non-affective psychotic disorders (NAPD) among first-generation migrants, and to compare with estimates for common mental disorders (CMD) to explore specificity of the effect.

STUDY DESIGN

We constructed a retrospective cohort of first-generation migrants to Ontario, Canada using linked population-based health administrative data (1992-2011; n = 1 964 884). We identified NAPD and CMD using standardized algorithms. We used modified Poisson regression models to estimate incidence rate ratios (IRR) for each factor to assess its effect on the risk of each outcome.

STUDY RESULTS

Nearly 75% of cases of NAPD met the case definition for a CMD prior to the first diagnosis of psychosis. Our findings suggest that younger age at migration, male sex, being of African-origin, and not having proficiency in national languages had a specificity of effect for a higher risk of NAPD. Among migrants who were over 19 years of age at landing, higher pre-migratory education and being married/common-law at landing showed specificity of effect for a lower risk of NAPD. Migrant class, rurality of residence after landing, and post-migration neighborhood-level income showed similar effects across disorders.

CONCLUSIONS

Our findings help identify high-risk groups to target for intervention. Identifying factors that show specific effects for psychotic disorder, rather than mental disorders more broadly, are important for informing prevention and early intervention efforts.

Involuntary psychiatric hospitalization among migrants in Italy: A matched sample study

BACKGROUND

Immigrants in Europe appear to be at higher risk of psychiatric coercive interventions. Involuntary psychiatric hospitalization poses significant ethical and clinical challenges. Nonetheless, reasons for migration and other risk factors for involuntary treatment were rarely addressed in previous studies. The aims of this study are to clarify whether immigrant patients with acute mental disorders are at higher risk to be involuntarily admitted to hospital and to explore clinical and migratory factors associated with involuntary treatment.

METHODS

In this cross-sectional matched sample study, we compared the rates of involuntary treatment in a sample of first-generation immigrants admitted in a Psychiatric Intensive Care Unit of a large metropolitan academic hospital to their age-, gender-, and psychiatric diagnosis-matched native counterparts. Clinical, sociodemographic, and migratory variables were collected. The Brief Psychiatric Rating Scale-expanded (BPRS-E) and the Clinical Global Impression-Severity (CGI-S) scale were administered. McNemar test was used for paired categorical variables and a binary logistic regression analysis was performed.

RESULTS

A total of 234 patients were included in the analysis. Involuntary treatment rates were significantly higher in immigrants as compared to their matched natives (32% vs. 24% respectively; p < .001). Among immigrants, involuntary hospitalization was found to be more frequent in those patients whose length of stay in Italy was less than 2 years (OR = 4.2, 95% CI [1.4-12.7]).

CONCLUSION

Recently arrived immigrants appear to be at higher risk of involuntary admission. Since coercive interventions can be traumatic and negatively affect outcomes, strategies to prevent this phenomenon are needed.
