Abstract
Introduction Cultural variety in expressed symptom presentations of mental health problems creates difficulties in transcultural diagnostic assessments. This emphasizes the need of culturally sensitive diagnostic tools like the Cultural Formulation Interview (CFI). Although the CFI is being implemented worldwide there is a lack of studies analyzing what kind of information it provides when used with new patients in routine psychiatric assessments, and how CFI information contributes to diagnostic evaluations. This study aimed to find out what information the CFI questions revealed when used with non-native Swedish speaking patients. We also wanted to understand how the CFI may facilitate identification of psychiatric diagnoses among these patients. Materials and methods The CFI was used as part of a routine clinical psychiatric assessment in an outpatient clinic in Sweden. Interpreters were used in the consultations when needed. A qualitative thematic analysis was used to analyze the documented CFI answers from non-native speaking patients. Results We found that the CFI information contained contextualized descriptions of dysfunction and current life conditions, as well as expressions of emotions, often described along with somatic terms. Discussion Our results indicate that the narrative approach of the CFI, giving contextualized information about distress and functioning, can facilitate clinicians' identification of psychiatric symptoms when language, psychiatric terms and understandings are not shared between patient and clinician.

Anderson KK, Rodrigues R. Differences in clinical presentation at first hospitalization and the impact on involuntary admissions among first-generation migrant groups with non-affective psychotic disorders. Soc Psychiatry Psychiatr Epidemiol 2023; 58:1329-1341. [PMID: 36922459 DOI: 10.1007/s00127-023-02465-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 03/08/2023] [Indexed: 03/18/2023]
Abstract
BACKGROUND Some migrant and ethnic minority groups have a higher risk of coercive pathways to care; however, it is unclear whether differences in clinical presentation contribute to this risk. We sought to assess: (i) whether there were differences in clinician-rated symptoms and behaviours across first-generation immigrant and refugee groups at the first psychiatric hospitalization after psychosis diagnosis, and (ii) whether these differences accounted for disparities in involuntary admission. METHODS Using population-based health administrative data from Ontario, Canada, we constructed a sample (2009-2013) of incident cases of non-affective psychotic disorder followed for two years to identify first psychiatric hospitalization. We compared clinician-rated symptoms and behaviours at admission between first-generation immigrants and refugees and the general population, and adjusted for these variables to ascertain whether the elevated prevalence of involuntary admission persisted. RESULTS Immigrants and refugee groups tended to have lower ratings for affective symptoms, self-harm behaviours, and substance use, as well as higher levels of medication nonadherence and poor insight. Immigrant groups were more likely to be perceived as aggressive and a risk of harm to others, and both groups were perceived as having self-care issues. Adjustment for perceived differences in clinical presentation at admission did not attenuate the higher prevalence of involuntary admission for immigrant and refugee groups. CONCLUSIONS First-generation migrant groups may differ in clinical presentation during the early course of psychotic illness, although these perceived differences did not explain the elevated rates of involuntary admission. Further research using outpatient samples and tools with established cross-cultural validity are warranted.

Abstract
BACKGROUND AND AIMS Social determinants of health (SDoHs) impact the development and course of schizophrenia-spectrum psychotic disorders (SSPDs). Yet, we found no published scholarly reviews of psychometric properties and pragmatic utility of SDoH assessments among people with SSPDs. We aim to review those aspects of SDoH assessments. STUDY DESIGN PsychInfo, PubMed, and Google Scholar databases were examined to obtain data on reliability, validity, administration process, strengths, and limitations of the measures for SDoHs identified in a paired scoping review. STUDY RESULTS SDoHs were assessed using different approaches including self-reports, interviews, rating scales, and review of public databases. Of the major SDoHs, early-life adversities, social disconnection, racism, social fragmentation, and food insecurity had measures with satisfactory psychometric properties. Internal consistency reliabilities-evaluated in the general population for 13 measures of early-life adversities, social disconnection, racism, social fragmentation, and food insecurity-ranged from poor to excellent (0.68-0.96). The number of items varied from 1 to more than 100 and administration time ranged from less than 5 minutes to over an hour. Measures of urbanicity, low socioeconomic status, immigration status, homelessness/housing instability, and incarceration were based on public records or targeted sampling. CONCLUSIONS Although the reported assessments of SDoHs show promise, there is a need to develop and test brief but validated screening measures suitable for clinical application. Novel assessment tools, including objective assessments at individual and community levels utilizing new technology, and sophisticated psychometric evaluations for reliability, validity, and sensitivity to change with effective interventions are recommended, and suggestions for training curricula are offered.

ETHNICITY & HEALTH 2022; 27:1123-1146. [PMID: 33316171 DOI: 10.1080/13557858.2020.1857338] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/21/2020] [Accepted: 11/24/2020] [Indexed: 06/12/2023]
Abstract
OBJECTIVES To gain insight into (1) the unfulfilled instrumental and affective needs of Turkish-Dutch and Moroccan-Dutch older cancer patients/survivors, (2) the barriers perceived by healthcare professionals in fulfilling these needs, and (3) how the Health Communicator, a multilingual eHealth tool, can support the fulfillment of patients'/survivors' needs, and decrease professionals' barriers. DESIGN We conducted a pre-implementation study of the Health Communicator using semi-structured interviews with Turkish-Dutch (n = 10; mean age = 69.10) and Moroccan-Dutch (n = 9; mean age = 69.33) older cancer patients/survivors, and held two focus groups with general practitioners (GPs; n = 7; mean age 45.14) and oncology nurses (ONs; n = 5; mean age = 49.60). Topic list consisted of questions related to needs and perceived barriers. Analysis was based on grounded theory. The acceptance of the Health Communicator was inquired by questions based on the concepts of the Technology Acceptance Model, and analyzed deductively. RESULTS Patients/survivors reported unfulfilled needs concerning: (1) information about cancer (treatment), (2) information about the healthcare system, (3) possibilities regarding psychosocial support, and (4) doctor-patient relationship. Among professionals, the main perceived barriers were: (1) patients'/survivors' low health literacy and language barrier, (2) cultural taboo, (3) lack of insight into patients' instrumental needs, and (4) patients'/survivors' lack of trust in Dutch healthcare. Both patients/survivors and professionals thought that implementing the Health Communicator could be effective in fulfilling most of the needs and decreasing the barriers. However, a majority of the patients/survivors were hesitant regarding the use of it, because they found it too difficult to use. Professionals showed a positive intention towards using the Health Communicator. CONCLUSIONS To enhance patient participation among older migrant cancer patients/survivors, the Health Communicator is, under certain conditions, a promising tool for fulfilling patients'/survivors' unfulfilled instrumental and affective needs and for bridging barriers perceived by professionals.

First perinatal psychiatric episode among refugee and family-reunified immigrant women compared to Danish-born women: a register-based study. Soc Psychiatry Psychiatr Epidemiol 2021; 56:2239-2250. [PMID: 34008058 DOI: 10.1007/s00127-021-02104-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Accepted: 05/10/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE This study aimed at examining psychiatric morbidity in the perinatal period among refugees and family-reunified immigrants compared to Danish-born women, including predictors of psychiatric morbidity according to migration history. METHODS Inclusion criteria were women who had a residence permit in Denmark and gave birth to a live child between 1 April 1998 and 31 December 2014. The study included 7804 refugee women, 21,257 family-reunified women, and 245,865 Danish-born women. We estimated Odds Ratios (ORs) of having a first-time perinatal psychiatric episode (PPE) and specific risk for affective, psychotic, and neurotic disorders. RESULTS Compared with Danish-born women, women family-reunified with immigrants had lower (aOR 0.37, 95% CI 0.22-0.64) and refugees had higher ORs of PPE (OR 1.46, 95% CI 1.22-1.76). In fully adjusted models, refugees no longer presented increased risk of PPE (OR 1.16, 95% CI 0.95-1.42) but showed higher ORs for psychotic (aOR 4.72, 95% CI 2.18-9.84) and neurotic disorders (aOR 1.31, 95% CI 1.01-1.72). Women family-reunified with refugees and to Nordic citizens had higher ORs of psychotic disorders. Among migrants, refugees had higher ORs of PPE. CONCLUSIONS Results suggest that elevation in risk of PPE among refugees compared to Danish-born may be related to higher likelihood of poverty and single-parenting among refugees. Still, refugees appear to have increased risk for neurotic and psychotic disorders. In contrast, family-reunified to immigrants may have lower risk of PPE. Maternal health programs need to focus on promotion of mental health and tackle social risks that disproportionately affect immigrant women, particularly refugees.

Abstract
BACKGROUND Ethnic minority groups in Western countries face an increased risk of psychotic disorders. Causes of this long-standing public health inequality remain poorly understood. We investigated whether social disadvantage, linguistic distance and discrimination contributed to these patterns. METHODS We used case-control data from the EUropean network of national schizophrenia networks studying Gene-Environment Interactions (EU-GEI) study, carried out in 16 centres in six countries. We recruited 1130 cases and 1497 population-based controls. Our main outcome measure was first-episode ICD-10 psychotic disorder (F20-F33), and exposures were ethnicity (white majority, black, mixed, Asian, North-African, white minority and other), generational status, social disadvantage, linguistic distance and discrimination. Age, sex, paternal age, cannabis use, childhood trauma and parental history of psychosis were included as a priori confounders. Exposures and confounders were added sequentially to multivariable logistic models, following multiple imputation for missing data. RESULTS Participants from any ethnic minority background had crude excess odds of psychosis [odds ratio (OR) 2.03, 95% confidence interval (CI) 1.69-2.43], which remained after adjustment for confounders (OR 1.61, 95% CI 1.31-1.98). This was progressively attenuated following further adjustment for social disadvantage (OR 1.52, 95% CI 1.22-1.89) and linguistic distance (OR 1.22, 95% CI 0.95-1.57), a pattern mirrored in several specific ethnic groups. Linguistic distance and social disadvantage had stronger effects for first- and later-generation groups, respectively. CONCLUSION Social disadvantage and linguistic distance, two potential markers of sociocultural exclusion, were associated with increased odds of psychotic disorder, and adjusting for these led to equivocal risk between several ethnic minority groups and the white majority.

Abstract
BACKGROUND A higher incidence of psychotic disorders has been consistently reported among black and other minority ethnic groups, particularly in northern Europe. It is unclear whether these rates have changed over time. METHODS We identified all individuals with a first episode psychosis who presented to adult mental health services between 1 May 2010 and 30 April 2012 and who were resident in London boroughs of Lambeth and Southwark. We estimated age-and-gender standardised incidence rates overall and by ethnic group, then compared our findings to those reported in the Aetiology and Ethnicity of Schizophrenia and Other Psychoses (ÆSOP) study that we carried out in the same catchment area around 10 years earlier. RESULTS From 9109 clinical records we identified 558 patients with first episode psychosis. Compared with ÆSOP, the overall incidence rates of psychotic disorder in southeast London have increased from 49.4 (95% confidence interval (CI) 43.6-55.3) to 63.1 (95% CI 57.3-69.0) per 100 000 person-years at risk. However, the overall incidence rate ratios (IRR) were reduced in some ethnic groups: for example, IRR (95% CI) for the black Caribbean group reduced from 6.7 (5.4-8.3) to 2.8 (2.1-3.6) and the 'mixed' group from 2.7 (1.8-4.2) to 1.4 (0.9-2.1). In the black African group, there was a negligible difference from 4.1 (3.2-5.3) to 3.5 (2.8-4.5). CONCLUSIONS We found that incidence rates of psychosis have increased over time, and the IRR varied by the ethnic group. Future studies are needed to investigate more changes over time and determinants of change.

Abstract
INTRODUCTION First episode psychosis (FEP) disproportionately affects rangatahi (young) Māori, the Indigenous people of New Zealand, but little is known about factors contributing to this inequity. This study describes a cohort of rangatahi Māori and young non-Māori with FEP, and explores ethnic differences in incidence rates, and the contribution of deprivation, urbanicity and substance use. METHODS Māori and young non-Māori, aged 13-25 at the time of the first recorded psychosis-related diagnoses, were identified from within Statistics NZ's Integrated Data Infrastructure (IDI), between 2009 and 2012. To estimate age-standardised FEP incidence rates, the population-at-risk was estimated using IDI-based usual resident population estimates for 2009-2012, stratified by ethnicity and single year of age. Poisson regression models were used to estimate ethnic differences in FEP incidence adjusted for age, gender, deprivation, and urban-rural area classification. RESULTS A total of 2412 young people with FEP (40% Māori, 60% non-Māori) were identified. Māori were younger, and more likely to live in deprived and rural communities and be diagnosed with schizophrenia. Substance induced psychosis was uncommon. The unadjusted age-standardised FEP incidence rate ratio was 2.48 (95% CI: 2.29-2.69) for rangatahi Māori compared with young non-Māori. While adjusting for age, sex, deprivation and urban rural area classification reduced ethnic differences in incidence, rangatahi Māori were still more than twice as likely to have been diagnosed with FEP compared to young non-Māori. CONCLUSIONS This study confirms previous findings of elevated rates of psychosis among rangatahi Māori. The difference in rates between Māori and non-Māori were attenuated but remained after adjustment for deprivation and urbanicity.

Abstract
BACKGROUND Previous studies have shown an elevated risk of psychotic symptoms (PS) and experiences (PEs) among ethnic minority groups, with significant variation between groups. This pattern may be partially attributable to the unfavorable socio-environmental conditions that surround ethnic minority groups. Perceived ethnic discrimination (PED) in particular has been a salient putative risk factor to explain the increased risk. METHODS We conducted a systematic literature review and meta-analysis to assess the impact of PED on reporting PS/PEs in ethnic minorities. This review abides by the guidelines set forth by Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The included studies were obtained from the databases: Medline, PsycINFO, and Web Of Science. Sub-group analyses were performed assessing the effect of PED in different subtypes of PS, the influence of ethnicity and moderating/mediating factors. RESULTS Seventeen studies met the inclusion criteria, and nine were used to conduct the meta-analysis. We found a positive association between PED and the occurrence of PS/PEs among ethnic minorities. The combined odds ratio were 1.77 (95% CI 1.26-2.49) for PS and 1.94 (95% CI 1.42-2.67) for PEs. We found that the association was similar across ethnic groups and did not depend on the ethnic origin of individuals. Weak evidence supported the buffering effects of ethnic identity, collective self-esteem and social support; and no evidence supported the moderating effect of ethnic density. Sensitivity to race-based rejection significantly but only slightly mediated the association. CONCLUSION These findings suggest that PED is involved in the increased risk of PS/PEs in ethnic minority populations.

[PMID: 30722795 PMCID: PMC7083571 DOI: 10.1017/s0033291719000035] [Citation(s) in RCA: 115] [Impact Index Per Article: 28.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2018] [Revised: 11/15/2018] [Accepted: 01/04/2019] [Indexed: 11/06/2022]
Abstract
BACKGROUND The aims of this meta-analysis are (i) to estimate the pooled relative risk (RR) of developing non-affective psychotic disorder (NAPD) and affective psychotic disorder (APD) among migrants and their children; (ii) to adjust these results for socioeconomic status (SES); (iii) to examine the sources of heterogeneity that underlie the risk of NAPD. METHODS We included population-based incidence studies that reported an age-adjusted RR with 95% confidence interval (CI) published 1 January 1977-12 October 2017 and used a random-effects model. RESULTS We retrieved studies performed in Europe (n = 43), Israel (n = 3), Canada (n = 2) and Australia (n = 1). The meta-analysis yielded a RR, adjusted for age and sex, of 2.13 (95% CI 1.99-2.27) for NAPD and 2.94 (95% CI 2.28-3.79) for APD. The RRs diminished, but persisted after adjustment for SES. With reference to NAPD: a personal or parental history of migration to Europe from countries outside Europe was associated with a higher RR (RR = 2.94, 95% CI 2.63-3.29) than migration within Europe (RR = 1.88, 95% 1.62-2.18). The corresponding RR was lower in Israel (RR = 1.22; 0.99-1.50) and Canada (RR = 1.21; 0.85-1.74). The RR was highest among individuals with a black skin colour (RR = 4.19, 95% CI 3.42-5.14). The evidence of a difference in risk between first and second generation was insufficient. CONCLUSIONS Positive selection may explain the low risk in Canada, while the change from exclusion to inclusion may do the same in Israel. Given the high risks among migrants from developing countries in Europe, social exclusion may have a pathogenic role.

Abstract
BACKGROUND We assessed whether the risk of various psychotic disorders and non-psychotic bipolar disorder (including mania) varied by migrant status, a region of origin, or age-at-migration, hypothesizing that risk would only be elevated for psychotic disorders. METHODS We established a prospective cohort of 1 796 257 Swedish residents born between 1982 and 1996, followed from their 15th birthday, or immigration to Sweden after age 15, until diagnosis, emigration, death, or end of 2011. Cox proportional hazards models were used to model hazard ratios by migration-related factors, adjusted for covariates. RESULTS All psychotic disorders were elevated among migrants and their children compared with Swedish-born individuals, including schizophrenia and schizoaffective disorder (adjusted hazard ratio [aHR]migrants: 2.20, 95% CI 1.96-2.47; aHRchildren : 2.00, 95% CI 1.79-2.25), affective psychotic disorders (aHRmigrant1.42, 95% CI 1.25-1.63; aHRchildren: 1.22 95% CI 1.07-1.40), and other non-affective psychotic disorders (aHRmigrant: 1.97, 95% CI 1.81-2.14; aHRchildren: 1.68, 95% CI 1.54-1.83). For all psychotic disorders, risks were generally highest in migrants from Africa (i.e. aHRschizophrenia: 5.24, 95% CI 4.26-6.45) and elevated at most ages-of-migration. By contrast, risk of non-psychotic bipolar disorders was lower for migrants (aHR: 0.58, 95% CI 0.52-0.64) overall, and across all ages-of-migration except infancy (aHR: 1.20; 95% CI 1.01-1.42), while risk for their children was similar to the Swedish-born population (aHR: 1.00, 95% CI 0.93-1.08). CONCLUSIONS Increased risk of psychiatric disorders associated with migration and minority status may be specific to psychotic disorders, with exact risk dependent on the region of origin.

Abstract
Understanding the excess risk of psychotic disorders in migrant and ethnic minority groups has long been an important research focus in psychiatric epidemiology and public mental health. Heterogeneity between migrant groups based on the region of origin, minority status and other socioeconomic factors may provide clues as to the underlying aetiological mechanisms explaining this risk, as well as informing our general understanding of psychotic disorders. Nonetheless, disentangling the mechanisms underlying this association has been the focus of more speculation and theory to date than empirical research. Now more than ever, we need to move beyond studies which demonstrate excess rates in migrant and ethnic minority groups to novel population-based studies which identify the determinants and mechanisms through which this risk is shaped. In this paper, we review the main hypotheses proposed to explain these disparities and the current level of support for them. We then highlight recent evidence from epidemiology and neuroscience which provides important new clues in our understanding of the aetiology of psychotic disorders. We concluded with suggestions for future interdisciplinary research to prevent this public mental health inequality within a generation.

Abstract
Psychotic symptoms (PS) are experienced by a substantial proportion of the general population. When not reaching a threshold of clinical relevance, these symptoms are defined as psychotic experiences (PEs) and may exist on a continuum with psychotic disorders. Unfavorable socio-environmental conditions, such as ethnic minority position (EMP) and migrant status (MS), may increase the risk of developing PS and PEs. We conducted an electronic systematic review and a meta-analysis assessing the role of EMP and MS for the development and persistence of PS in the general population. Sub-group analyses were performed investigating the influence of ethnic groups, host countries, age, types of PS, and scales. Twenty-four studies met our inclusion criteria. EMP was a relevant risk factor for reporting PS [odds ratio (OR) 1.44, 95% confidence interval (CI) 1.22-1.70) and PEs (OR 1.36, 95% CI 1.16-1.60). The greatest risk was observed in people from the Maghreb and the Middle East ethnic groups in Europe (OR 3.30, 95% CI 2.09-5.21), in Hispanic in the USA (OR 1.98, 95% CI 1.43-2.73), and in the Black populations (OR 1.85, 95% CI 1.39-2.47). We found a significant association between MS and delusional symptoms (OR 1.47, 95% CI 1.33-1.62). We found no association between EMP and persistence of PEs.EMP was associated with increased risk of reporting PS and PEs, and the risk was higher in ethnic groups facing deprivation and discrimination. We found an association between MS and delusional symptoms. These results raise questions about the precise role of socio-environmental factors along the psychosis continuum.

Abstract
PURPOSE A higher own-group ethnic density in the area of residence is often associated with a lower risk for psychotic disorder. For common mental disorders the evidence is less convincing. This study explores whether these findings are mirrored in data on dispensing of antipsychotics and antidepressants. METHODS Health insurance data on dispensed medication among all adults living in the four largest Dutch cities were linked to demographic data from Statistics Netherlands. Dispensing of antipsychotics and antidepressants in 2013 was analyzed in relation to the proportion of the own ethnic group in the neighborhood. RESULTS Higher own-group ethnic density was associated with lower dispensing of antipsychotics among the Moroccan-Dutch (N = 115,455), after adjusting for age, gender, and SES of the neighborhood (ORadj for the highest vs. the lowest density quintile = 0.72 [0.66-0.79]). However, this association vanished after adjustment for household composition (ORadj = 0.93 [0.85-1.03]). Similar results were found for the Turkish-Dutch (N = 105,460) (ORadj = 0.86 [0.76-0.96] and 1.05 [0.94-1.18]). For those of Surinamese (N = 147,123) and Antillean origin (N = 41,430), in contrast, the association between ethnic density and lower risk remained after each adjustment (P < 0.001). For antidepressants, a negative association with own-group ethnic density was consistently found for those of Antillean origin (ORadj = 0.62 [0.52-0.74]) only. CONCLUSION These data on dispensing of psychomedication confirm the ethnic density hypothesis for psychosis alongside earlier equivocal findings for other mental disorders. The negative association between own-group ethnic density and dispensing of antipsychotics among the Moroccan- and Turkish-Dutch may be explained, at least in part, by a favourable household composition (i.e., living in a family) in high-density neighborhoods.

Abstract
BACKGROUND Black and minority ethnic (BME) groups are known to have higher prevalences of psychotic disorders and are over-represented in western penitentiaries and forensic psychiatric institutions. Research from regular mental healthcare settings suggests that they could show different and more severe psychotic symptoms. Aims To explore ethnic variations in severity of symptomatology of BME and non-BME detainees with psychotic disorders. METHOD In this study, 824 patients with psychotic disorders from seven different ethnic groups, imprisoned in a penitentiary psychiatric centre in the Netherlands, were compared on symptom severity and symptom representation using the BPRS-E clinical interview. Data were analysed by means of a multilevel analysis. RESULTS BME patients with psychotic disorders are over-represented in forensic psychiatry, and symptom profiles of prisoners with psychotic disorders vary by ethnicity. Additionally, severity levels of overall psychopathology differ between ethnic groups: patients with an ethnic majority status show more severe levels of psychopathology compared with BME patients. CONCLUSIONS There are differences in symptom severity and symptom profiles between BME patients and non-BME patients. Disregarding these differences could have an adverse effect on the outcome of the treatment. Possible explanations and clinical impact are discussed. Declaration of interest None.

Abstract
A high prevalence of mental illness has been reported in asylum seekers. The present cross-sectional study examined suicidal thoughts, treatment modalities (outpatient crisis intervention, inpatient care), and their determinants in asylum seekers (n = 119) and permanent residents (n = 120) attending the same outpatient clinic in Geneva, Switzerland. The most frequent diagnoses were depressive disorders (64.7%) and posttraumatic stress disorder (34.5%) in asylum seekers and psychotic (55.0%) and depressive disorders (33.3%) in permanent residents. The frequency of suicidal thoughts was similar in both groups (>30%). Asylum seekers benefited from outpatient crisis intervention more frequently than residents did (26.9% vs. 5.8%), whereas inpatient care was less frequent (25.2% vs. 44.2%). In asylum seekers, acute suicidal thoughts were associated with increased frequency of outpatient crisis interventions, and, suicidal thoughts, psychosis, or personality disorders were associated with higher rates of hospitalization. Documenting clinical characteristics and service utilization of asylum seekers is a prerequisite to organizing targeted interventions.

Abstract
PURPOSE To estimate the effect of selective sampling on first contact (FC) studies of the relation between migration and schizophrenia. METHODS We compared the FC method directly with a more inclusive longitudinal psychiatric register (LPR) method, by letting both methods estimate age and sex adjusted incidence rate ratios (IRR) in the population of The Hague aged 20-54 years, for the three largest migrant groups (first and second generation Caribbean, Turkish, and Moroccan) relative to the native Dutch population. RESULTS Both methods found that the adjusted IRR was higher for migrants than for native Dutch [all migrants IRR = 1.70 (95% Cl 1.30-2.21) for the LPR method and 1.91 (95% Cl 1.15-3.25) for the FC]. The IRR for Moroccans was significantly lower in the LPR [IRR 2.69 (95% 2.10-3.41)] than in the FC study [4.81 (3.41-6.68)]. The FC method was relatively more inclusive for migrants presenting at earlier ages or with shorter durations of prior treatment (DPT) than the native Dutch. This resulted in differential sampling and artificially higher IRRs for Moroccan and, to a lesser extent, Turkish migrants. CONCLUSION We confirm that the incidence of schizophrenia is raised twofold for migrants compared to nonmigrants. Using the LPR method, however, IRR estimates were less pronounced for most migrant groups than in a high quality FC study conducted in the same population. The FC method may overestimate the risk of schizophrenia for migrant groups who seek first mental health at a relatively younger age, or who present directly with schizophrenia.

Abstract
PURPOSE Epidemiological studies in the Netherlands have reported an excessive gender gap in the risk for non-affective psychotic disorder (NAPD) among immigrants from Morocco with a higher risk elevation in males compared to females. We examined the consistency of these findings and their generalizability to immigrants from the Maghreb (Mauritania, Morocco, Algeria, Tunisia and Libya) in other European countries. METHODS Systematic review and meta-analysis. Medline, PsychINFO and EMBASE databases were searched for publications in the period from January 1970 to April 2014. We included incidence and prevalence studies of non-affective psychotic disorder (NAPD) among migrants from the Maghreb in Europe and studies of subclinical psychotic symptoms (SPS) in representative samples. A meta-analysis was performed on the subgroup of incidence studies. RESULTS Five incidence and three prevalence studies of NAPD, and two prevalence studies of SPS, conducted in the Netherlands (n=7), Belgium (n=1), France (n=1) and Italy (n=1) met our inclusion criteria. Across all research designs, the risks of NAPD and SPS were consistently increased among male, not female immigrants from the Maghreb. The meta-analysis of incidence studies of NAPD yielded male-to-female risk ratios of 5.1 [95 % confidence interval (CI) 3.1-8.4] for migrants from the Maghreb, 2.0 (95 % CI 1.6-2.5) for other migrant groups, and 1.8 (95 % CI 1.3-2.5) for non-migrant Europeans. CONCLUSIONS The marked gender gap in psychosis risk among migrants from the Maghreb appears a consistent finding, foremost among the Moroccan-Dutch. The small number of studies limits the strength of conclusions that can be drawn about countries other than the Netherlands. Achievement-expectation mismatch, social marginalization and an increased prevalence of illicit drug use are possible explanations.

Abstract
Previous studies have reported a higher incidence of psychosis in Moroccan immigrants in the Netherlands than among native-born residents. However, this disparity was substantially attenuated when cultural differences in symptom presentation were taken into account. To better understand the impact of different diagnostic procedures on incidence rates, we examined the effects of the use of a culturally sensitive diagnostic interview, compared to a standard semi-structured diagnostic interview, on symptom profiles among Moroccan immigrant and native Dutch patients in the Netherlands. A total of 26 Dutch and 26 Moroccan patients referred with a possible first psychosis diagnosis were interviewed twice: once with the standard version and once with a culturally adapted version of the Comprehensive Assessment of Symptoms and History questionnaire (CASH and CASH-CS, respectively). Among native Dutch patients, symptoms profiles based on CASH and CASH-CS interviews were very similar. By contrast, among Moroccan immigrant patients, symptom profiles based on CASH and CASH-CS interviews differed substantially, with more mania symptoms (+30%; p < .05) and fewer delusions (-31%; p < .05) reported when using the CASH-CS. These results suggest that the over-diagnosis of schizophrenia in Moroccan immigrants with a first psychosis referral may be related to a tendency to under-detect mood symptoms and over-detect positive psychotic symptoms when a standard diagnostic procedure is used. This bias may be corrected, at least in part, by the use of a culturally sensitive interview instrument such as the CASH- CS.

Abstract
This study evaluated the use of the Outline for Cultural Formulation (OCF) from the DSM-IV in the diagnosis of immigrants and refugee patients at an outpatient psychiatric clinic in Sweden. Using the OCF in conjunction with standard diagnostic procedures led to major revisions of diagnoses for 56.5% of patients. Anxiety disorders, especially PTSD, constitute the disorder group in which the most changes were made. In order to understand how information from the OCF interview led clinicians to revise diagnoses, data from clinical discussions were analysed through qualitative content analysis. This revealed four major themes related to the reevaluation, and at times confirmation, of given clinical psychiatric diagnoses: new information; expression of distress in emotional language; expression of distress in relation to life experiences; and improved understanding of the patient's suffering. The findings suggest that the OCF may be useful for: (a) formulating culture in relation to illness experiences, (b) contextualising diagnostic categorisation, and (c) improving overall understanding of the patient that may facilitate individualised planning of treatment and therapy.

Abstract
BACKGROUND The risk for psychotic disorders is increased for many ethnic minority groups and may develop in early childhood. This study investigated whether the prevalence of psychotic experiences (PE) with high impact is higher among ethnic minority youth compared to majority youth and examined the significance of these PE. METHOD A school-based study assessed a large community sample of 1545 ethnic minority and majority children in The Netherlands (mean age 12.98 ± 1.81 years). The Dutch (n = 702, 45.4%), Moroccan-Dutch (n = 400, 25.9%) and Turkish-Dutch (n = 170, 11.0%) ethnic groups could be studied separately. Self-report questionnaires on PE, impact and cultural context were administered. RESULTS Prevalence of PE with high impact was 3.1% in Dutch, 9.5% in Moroccan-Dutch and 7.1% in Turkish-Dutch youth. Compared to Dutch youth, odds ratios were 3.0 [95% confidence interval (CI) 1.7-5.1] for Moroccan-Dutch youth and 2.2 (95% CI 1.1-4.6) for Turkish-Dutch youth. Differences were not explained by cultural or religious differences. CONCLUSIONS The increased risk for psychotic disorders in ethnic minorities may already be detectable in childhood, since PE with high impact were more common among ethnic minority youth compared to majority youth. The additional measurement of impact of PE appears to be a valid approach to identify those children at risk to develop psychotic or other more common psychiatric disorders.

Abstract
The Outline for Cultural Formulation (OCF) introduced with DSM-IV provided a framework for clinicians to organize cultural information relevant to diagnostic assessment and treatment planning. However, use of the OCF has been inconsistent, raising questions about the need for guidance on implementation, training, and application in diverse settings. To address this need, DSM-5 introduced a cultural formulation interview (CFI) that operationalizes the process of data collection for the OCF. The CFI includes patient and informant versions and 12 supplementary modules addressing specific domains of the OCF. This article summarizes the literature reviews and analyses of experience with the OCF conducted by the DSM-5 Cross-Cultural Issues Subgroup (DCCIS) that informed the development of the CFI. We review the history and contents of the DSM-IV OCF, its use in training programs, and previous attempts to render it operational through questionnaires, protocols, and semi-structured interview formats. Results of research based on the OCF are discussed. For each domain of the OCF, we summarize findings from the DCCIS that led to content revision and operationalization in the CFI. The conclusion discusses training and implementation issues essential to service delivery.

Abstract
The population of the Netherlands has become increasingly diverse in terms of ethnicity and religion, and anti-immigrant attitudes have become more apparent. At the same time, interest in issues linked to transcultural psychiatry has grown steadily. The purpose of this article is to describe the most important results in Dutch transcultural psychiatric research in the last decade and to discuss their relationship with relevant social and political developments in the Netherlands. All relevant PhD theses (N = 27) between 2000 and 2011 were selected. Screening of Dutch journals in the field of transcultural psychiatry and medical anthropology and a PubMed query yielded additional publications. Forensic and addiction psychiatry were excluded from this review. The results of the review indicate three main topics: (a) the prevalence of psychiatric disorders and their relation to migration issues as social defeat and ethnic density, showing considerable intra- and interethnic differences in predictors and prevalence rates, (b) the social position of refugees and asylum seekers, and its effect on mental health, showing especially high risk among asylum seekers, and (c) the patterns of health-seeking behaviour and use of mental health services, showing a differentiated picture among various migrant groups. Anthropological research brought additional knowledge on all the above topics. The overall conclusion is that transcultural psychiatric research in the Netherlands has made a giant leap since the turn of the century. The results are of international importance and invite redefinition of the relationship between migration and mental health, and reconsideration of its underlying mechanisms in multiethnic societies.

Abstract
BACKGROUND Acculturation is the phenomenon that results when a group with one culture comes into continuous contact with a host culture. AIMS To investigate the correlation between acculturation and psychotic symptomatology in a group of immigrants suffering from psychosis and to explore differences in demographic factors related with the acculturation process between individuals with and without psychosis. METHODS Sixty-five patients and 317 non-psychotic immigrants were interviewed using the Immigrant Acculturation Scale (IAS) and a structured questionnaire for demographic data. The Positive and Negative Syndrome Scale (PANSS), the Calgary Depression Scale for Schizophrenia (CDSS) and the Global Assessment of Functioning (GAF) were also administered to all immigrants suffering from psychosis. RESULTS Total IAS scores, as well as IAS everyday life scores, were positively correlated with GAF scores. IAS everyday life score in the patient group related with religion, marital status, gender and years in Greece, while in the non-psychosis group it was related with gender and years in Greece. IAS wishful orientation/nostos (the strong desire for one's homeland) related with religion in both groups. The IAS identity in the psychosis group did not show any significant relation with any of the variables, while in the non-patient group, it was related with marital status, gender and years in Greece. Age, duration of residence in Greece and higher adoption of Greek ethnic identity were the variables that differentiated the two groups of immigrants. CONCLUSION Acculturation in immigrants suffering from psychosis could be seen as a process that does not correlate strongly with the severity of the symptomatology but is probably influenced by different set of factors.

Abstract
PURPOSE OF REVIEW This article reviews the recent literature about migration, ethnic minority position and the risk of psychotic disorders. RECENT FINDINGS A meta-analysis found that both first and second-generation migrants have on average a two-fold increase in risk for psychotic disorders. In the Netherlands, the risk was most elevated for individuals who migrated in early childhood. Several studies investigated diagnostic ethnic bias and reported greater likelihood of schizophrenia diagnosis in ethnic minority patients at the cost of diagnosis of affective psychotic disorders. Neighbourhood ethnic density was related to prevalence of psychotic experiences in ethnic minority populations in the UK. Perceived discrimination was associated with severity of psychotic and depressive symptoms in ethnic minority patients. Both weak and strong ethnic identification, as well as experiences of social adversity, were related to risk for psychosis. Low neonatal vitamin D was associated with adult risk for psychosis and vitamin D levels in childhood were associated with nonclinical psychotic experiences. SUMMARY The risk for psychotic disorders is increased among ethnic minority populations. Experiences of social adversity and having a disadvantaged outsider status may explain the excess risk. More research is needed into potential biological mechanisms, including vitamin D.

Abstract
PURPOSE Incidence rates of psychotic disorders are higher in immigrant groups compared to native populations. This increased risk may partly be explained by misdiagnosis. Neurocognitive deficits are a core feature of psychotic disorders, but little is known about the relationship between migration and cognition in psychotic disorders. We examined whether immigrant patients have cognitive deficits similar to non-immigrant patients, in order to investigate the plausibility of misdiagnosis as explanation for increased incidence rates. METHODS Patients who made first contact for non-affective psychotic disorder were assessed in the cognitive domains sustained attention, immediate recall and delayed recall. Immigrant patients were compared to Dutch patients on cognitive performance. RESULTS 407 Patients diagnosed with a non-affective psychotic disorder completed cognitive assessment (157 Dutch, 250 immigrants). Both Dutch and immigrant patients showed large cognitive deficits. Between-subgroup comparisons revealed large cognitive deficits for immigrants compared to Dutch, especially for immigrants from Morocco, Turkey and other non-Western countries. CONCLUSIONS These results indicate that immigrant status is associated with poorer cognitive functioning in early psychosis. The findings argue against diagnostic bias as an explanation for the increased incidence of psychotic disorders in immigrants.

Abstract
OBJECTIVE To explore differences in severity and nature of symptoms of first-episode psychosis (FEP) according to ethnic group and migrant status. METHOD We administered rating scales to assess positive and negative symptoms, as well as general psychopathology, to 301 consecutive patients presenting with an FEP within a defined catchment area in Montreal, Quebec, classified according to ethnicity and migrant status. Symptom scores of Euro-Canadian patients without a recent history of migration, that is, the reference group (n = 145), were compared with those of African and Afro-Caribbean (n = 39), Asian (n = 27), Central and South American (n = 15), Middle Eastern and North African (n = 24), and European and North American (n = 39) patients. RESULTS Except for referral source, there were no significant differences between ethnic groups on any demographic variables. The African and Afro-Caribbean group had a higher level of negative symptoms (especially alogia) and general psychopathology scores on the Positive and Negative Syndrome Scale (especially, uncooperativeness, preoccupation, and poor attention), compared with the reference group. Ethnic groups did not differ on the Scale for the Assessment of Positive Symptoms scores. CONCLUSIONS A comparison of FEP patients from different ethnic groups and native-born Euro-Canadians revealed no significant differences in the nature of positive symptoms at first presentation or in age at onset, suggesting that there was no evidence for the hypothesis that ethnic minorities are misdiagnosed as psychotic. Increased severity of negative symptoms and general psychopathology, specifically among the black ethnic minority group, may have implications for the role of ethnicity for the treatment and outcome of the initial episode of psychotic disorders.

Abstract
BACKGROUND Ethnicity has been associated with different incidence rates and different symptom profiles in young patients with psychotic-like disorders. No studies so far have examined the effect of ethnicity on symptoms in people with an At Risk Mental State (ARMS). METHOD In this cross-sectional study, we analysed the relationship between ethnicity and baseline data on the severity of psychopathology scores in 201 help-seeking patients who met the ARMS criteria and agreed to participate in the Dutch Early Detection and Intervention (EDIE-NL) trial. Eighty-seven of these patients had a non-Dutch ethnicity. We explored the possible mediating role of ethnic identity. RESULTS Higher rates of negative symptoms, and of anhedonia in particular, were found in the ethnic minority group. This result could be attributed mainly to the Moroccan-Dutch and Turkish-Dutch subgroups, who also presented with more depression symptoms when the groups were examined separately. The ethnic minority group displayed a lower level of ethnic group identity compared to the immigrants of the International Comparative Study of Ethnocultural Youth (ICSEY). Ethnic identity was inversely related to symptoms in the Moroccan-Dutch patient group. CONCLUSIONS The prevalence of more severe negative symptoms and depression symptoms in ethnic minority groups deserves more attention, as the experience of attenuated positive symptoms when accompanied by negative symptoms or distress has proven to be predictive for transition to a first psychotic episode.

Abstract
UNLABELLED Previous research has shown discrepancies between a standard diagnostic interview for schizophrenia (CASH) and a culture sensitive version of this instrument (CASH-CS) in Moroccan patients. More specifically we showed that among Moroccan immigrants the CASH-CS resulted in fewer patients with a diagnosis of schizophrenia compared with diagnoses based on the CASH, whereas for Native Dutch patients there was no difference between the CASH and the CASH-CS. The aim of the current study was to compare the predictive validity of a diagnosis of schizophrenia according to the CASH and CASH-CS. METHOD Thirty months after referral, 26 Moroccan and 26 native Dutch patients with a suspected first psychotic episode were compared with regard to 30-month diagnostic stability, symptom development, psychosocial functioning, medication use and hospitalization using baseline diagnoses based on the two versions of the CASH. RESULTS Moroccan patients who were diagnosed with schizophrenia using the standard CASH at baseline had a significantly better 30-month prognosis than native Dutch patients with the same CASH diagnosis. Prognosis of schizophrenia according to the CASH-CS was similar for Moroccans and native Dutch patients. Diagnostic stability according to the CASH was high for native Dutch (92%), but low for Moroccan patients (27%), whereas diagnostic stability according to the CASH-CS was high for both groups (85% and 81%, respectively). CONCLUSION These data raise questions regarding the validity of the standard CASH in Moroccan immigrants in The Netherlands and support the validity of the CASH-CS. As a consequence, there are serious doubts about the validity of previous studies showing an increased incidence of schizophrenia in immigrants using standard diagnostic procedures.

Abstract
The incidence of schizophrenia, as well as the symptoms, course, and outcomes for people so diagnosed seem to vary across some cultural contexts. The mechanisms by which cultural variations may protect one from or increase one's risk of developing schizophrenia remain unclear. Recent findings from transdisciplinary cross-cultural research, indicate ways that we may better understand how socioenvironmental and cultural variables interact with physiologic pathways relating psychosocial stress and psychotic symptoms, epigenetic changes, and people's use of culturally available tools to mitigate stress, in ways that may inform relevant, effective interventions for people diagnosed with psychotic disorders worldwide.

Abstract
The incidence of psychotic disorders is extremely high in several immigrant groups in Europe. This article describes the epidemiological evidence for increased incidence rates among immigrants compared with nonimmigrant populations and explores possible explanations for this excess risk. Potential causes not only involve factors acting at the level of the individual, but encompass the broader social context of neighborhoods and ethnic groups. Growing up and living in a disadvantaged ethnic minority position, characterized by a low social status, high degree of discrimination against the group and low neighborhood ethnic density, may lead to an increased risk of psychotic disorders, especially when individuals reject their minority status and when their social resources are insufficient to buffer the impact of adverse social experiences. Future research should refine measures of the social context, adopt a life-course perspective and should integrate social and neurobiological pathways.
