Urbanicity and rates of untreated psychotic disorders in three diverse settings in the Global South.

BACKGROUND: Extensive evidence indicates that rates of psychotic disorder are elevated in more urban compared with less urban areas, but this evidence largely originates from Northern Europe. It is unclear whether the same association holds globally. This study examined the association between urban residence and rates of psychotic disorder in catchment areas in India (Kancheepuram, Tamil Nadu), Nigeria (Ibadan, Oyo), and Northern Trinidad. METHODS: Comprehensive case detection systems were developed based on extensive pilot work to identify individuals aged 18-64 with previously untreated psychotic disorders residing in each catchment area (May 2018-April/May/July 2020). Area of residence and basic demographic details were collected for eligible cases. We compared rates of psychotic disorder in the more v. less urban administrative areas within each catchment area, based on all cases detected, and repeated these analyses while restricting to recent onset cases (<2 years/<5 years). RESULTS: We found evidence of higher overall rates of psychosis in more urban areas within the Trinidadian catchment area (IRR: 3.24, 95% CI 2.68-3.91), an inverse association in the Nigerian catchment area (IRR: 0.68, 95% CI 0.51-0.91) and no association in the Indian catchment area (IRR: 1.18, 95% CI 0.93-1.52). When restricting to recent onset cases, we found a modest positive association in the Indian catchment area. CONCLUSIONS: This study suggests that urbanicity is associated with higher rates of psychotic disorder in some but not all contexts outside of Northern Europe. Future studies should test candidate mechanisms that may underlie the associations observed, such as exposure to violence.

Cannabis use and psychotic disorders in diverse settings in the Global South: findings from INTREPID II.

BACKGROUND: Cannabis use has been linked to psychotic disorders but this association has been primarily observed in the Global North. This study investigates patterns of cannabis use and associations with psychoses in three Global South (regions within Latin America, Asia, Africa and Oceania) settings. METHODS: Case-control study within the International Programme of Research on Psychotic Disorders (INTREPID) II conducted between May 2018 and September 2020. In each setting, we recruited over 200 individuals with an untreated psychosis and individually-matched controls (Kancheepuram India; Ibadan, Nigeria; northern Trinidad). Controls, with no past or current psychotic disorder, were individually-matched to cases by 5-year age group, sex and neighbourhood. Presence of psychotic disorder assessed using the Schedules for Clinical Assessment in Neuropsychiatry and cannabis exposure measured by the World Health Organisation Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). RESULTS: Cases reported higher lifetime and frequent cannabis use than controls in each setting. In Trinidad, cannabis use was associated with increased odds of psychotic disorder: lifetime cannabis use (adj. OR 1.58, 95% CI 0.99-2.53); frequent cannabis use (adj. OR 1.99, 95% CI 1.10-3.60); cannabis dependency (as measured by high ASSIST score) (adj. OR 4.70, 95% CI 1.77-12.47), early age of first use (adj. OR 1.83, 95% CI 1.03-3.27). Cannabis use in the other two settings was too rare to examine associations. CONCLUSIONS: In line with previous studies, we found associations between cannabis use and the occurrence and age of onset of psychoses in Trinidad. These findings have implications for strategies for prevention of psychosis.

Parental bonding style and illness severity in a longitudinal study of individuals with first episode psychosis.

A parenting style with high amounts of control combined with low caring or nurturing behaviour has been reported in association with mental disorders including schizophrenia. However, the association of parenting style with illness severity in individuals with schizophrenia has never been evaluated retrospectively or over a longitudinal time course. In a subset (n = 84) of the participants included in the AESOP (Aetiology and Ethnicity in Schizophrenia and Other Psychoses)-10 study, we evaluated participants' perceptions of their own parents' bonding style at the time of their first episode of psychosis using the parental bonding instrument (PBI). We then examined the association between different bonding styles, illness course and severity, and global functioning over a 10-year follow-up. Participants who perceived that their fathers had a more caring and less controlling parenting style showed better functioning at follow-up. However, in contrast to previous research, participants who reported having been subject to uncaring and controlling parenting styles were not found to have a notably worse course of illness or symptom severity over the follow-up period. These results indicate that more optimal parental bonding styles may be associated with better overall functioning in individuals with psychosis but not with other measures of illness outcome.

Religion and Life Satisfaction: A Correlational Study of Undergraduate Students in Trinidad.

Religious behaviour tends to correlate positively with life satisfaction. The predictive power of this relationship is associated with various socio-demographic factors such as age, gender and religious affiliation. We investigated the relationship between religious involvement and life satisfaction in a multi-religious population of undergraduate medical students of the University of the West Indies. We used a cross-sectional design to assess 228 undergraduates (50 males and 178 females) on religiosity, religious well-being and life satisfaction using the Religious Orientation Test, Religious Well-Being subscale and the Satisfaction with Life Scale, respectively. Respondents also provided socio-demographic information such as age, gender and religious affiliation. "How religious one considers oneself" was the religiosity construct most significantly associated with life satisfaction while "frequency of prayer" was the least. Christians registered higher religiosity and religious well-being but non-Christians reported significantly higher life satisfaction. Muslim and Hindu scores on religiosity, religious well-being and life satisfaction were not statistically different. Females scored higher than males on religiosity (borderline significant, p = .054) and significantly higher on religious well-being (p < .01); however, there was no significant difference between males and females on life satisfaction. The "religious affiliation" group scored significantly higher on religiosity and religious well-being compared with the "no religious affiliation" group but there was no difference between these two groups on life satisfaction. Religiosity and religious well-being were overall significantly and positively associated with life satisfaction. However, in demographic groups where there was higher religiosity, for example females, Christians, people affiliated with a religion and older people, it was not associated with greater life satisfaction.

CBT in a Caribbean Context: A Controlled Trial of Anger Management in Trinidadian Prisons.

BACKGROUND: Anger causes significant problems in offenders and to date few interventions have been described in the Caribbean region. AIM: To evaluate a package of CBT-based Anger Management Training provided to offenders in prison in Trinidad. METHOD: A controlled clinical trial with 85 participants who participated in a 12-week prison-based group anger management programme, of whom 57 (67%: 16 control, 41 intervention) provided pretrial and posttrial outcome data at Times 1 and 2. RESULTS: Intervention and control groups were not directly comparable so outcome was analysed using t-tests. Reductions were noted for state and trait anger and anger expression, with an increase in coping skills for the intervention group. No changes were noted in the control group. The improvements seen on intervention were maintained at 4 month follow-up for a sub-group of participants for whom data were available. Several predictors of outcomes were identified.

Concepts of madness in diverse settings: a qualitative study from the INTREPID project.

BACKGROUND: In order to facilitate case identification of incident (untreated and recent onset) cases of psychosis and controls in three sites in India, Nigeria and Trinidad, we sought to understand how psychoses (or madness) were conceptualized locally. The evidence we gathered also contributes to a long history of research on concepts of madness in diverse settings. METHODS: We conducted focus group discussions and individual interviews to collect information about how informants in each site make sense of and respond to madness. A coding framework was developed and analyses of transcripts from the FGDs and interviews were conducted. RESULTS: Analyses suggest the following: a) disturbed behaviors are the primary sign of madness; b) madness is attributed to a wide range of causes; and, c) responses to madness are dictated by cultural and pragmatic factors. These findings are congruent with similar research that has been conducted over the past 50 years. CONCLUSIONS: The INTREPID research suggests that concepts about madness share similar features across diverse settings: a) terms for madness are often derived from a common understanding that involves disruptions in mental processes and capacities; b) madness is recognized mostly by disruptive behaviours or marked declines in functioning; c) causal attributions are varied; and, d) help-seeking is a complex process.

Searching for psychosis: INTREPID (1): systems for detecting untreated and first-episode cases of psychosis in diverse settings.

PURPOSE: Our understanding of psychotic disorders is largely based on studies conducted in North America, Europe and Australasia. Few methodologically robust and comparable studies have been carried out in other settings. INTREPID is a programme of research on psychoses in India, Nigeria, and Trinidad. As a platform for INTREPID, we sought to establish comprehensive systems for detecting representative samples of cases of psychosis by mapping and seeking to engage all professional and folk (traditional) providers and potential key informants in defined catchment areas. METHOD: We used a combination of official sources, local knowledge of principal investigators, and snowballing techniques. RESULTS: The structure of the mental health systems in each catchment area was similar, but the content (i.e., type, extent, and nature) differed. Tunapuna-Piarco (Trinidad), for example, has the most comprehensive and accessible professional services. By contrast, Ibadan (Nigeria) has the most extensive folk (traditional) sector. We identified and engaged in our detection system-(a) all professional mental health services in each site (in- and outpatient services-Chengalpet, 6; Ibadan, 3; Trinidad, 5); (b) a wide range of folk providers (Chengalpet, 3 major healing sites; Ibadan, 19 healers; Trinidad: 12 healers); and c) a number of key informants, depending on need (Chengalpet, 361; Ibadan, 54; Trinidad, 1). CONCLUSIONS: Marked differences in mental health systems in each catchment area illustrate the necessity of developing tailored systems for the detection of representative samples of cases with untreated and first-episode psychosis as a basis for robust, comparative epidemiological studies.

Gender differences in the association between childhood physical and sexual abuse, social support and psychosis.

PURPOSE: Childhood adversity (variously defined) is a robust risk factor for psychosis, yet the mitigating effects of social support in adulthood have not yet been explored. This study aimed to investigate the relationships between childhood sexual and physical abuse and adult psychosis, and gender differences in levels of perceived social support. METHODS: A sample of 202 individuals presenting for the first time to mental health services with psychosis and 266 population-based controls from south-east London and Nottingham, UK, was utilised. The Childhood Experience of Care and Abuse Questionnaire was used to elicit retrospective reports of exposure to childhood adversity, and the Significant Others Questionnaire was completed to collect information on the current size of social networks and perceptions of emotional and practical support. RESULTS: There was evidence of an interaction between severe physical abuse and levels of support (namely, number of significant others; likelihood ratio test χ(2) = 3.90, p = 0.048). When stratified by gender, there were no clear associations between childhood physical or sexual abuse, current social support and odds of psychosis in men. In contrast, for women, the highest odds of psychosis were generally found in those who reported severe abuse and low levels of social support in adulthood. However, tests for interaction by gender did not reach conventional levels of statistical significance. CONCLUSIONS: These findings highlight the importance of investigating the potential benefits of social support as a buffer against the development of adult psychosis amongst those, particularly women, with a history of early life stress.

Neighbourhoods & recovery from psychosis in Trinidad: A qualitative study.

•Various aspects of neighbourhood environments influence recovery from psychosis.•High levels of violence at the neighbourhood level may negatively affect recovery.•Social cohesion may be a protective factor that promotes recovery.•Normalisation of cannabis use and easy access to cannabis may also hinder recovery.•Community involvement is needed to design interventions targeting these factors.

Understanding mental health conditions and key coping strategies utilized during major lockdowns in the Caribbean based on Google trends searches.

The COVID-19 pandemic has prompted countries to implement extended Shelter in Place Orders (SIPOs) to restrict population movement and mitigate community spread. While these lockdown measures may be effective in containing the virus, they can substantially impact the population's well-being, potentially undermining their overall welfare. This study investigates whether major lockdowns implemented in the Caribbean produced differential changes in mental health among key English-Speaking Caribbean countries. More importantly, unlike past studies, we examine key coping strategies persons utilize during major lockdowns. Finally, this paper utilizes a novel near real-time high-frequency data source in Google Trends data analytics to assess mental health patterns and coping strategies among major Caribbean countries. Based on the results of difference-in-difference and event study models, we find positive and significant increases in searches for fear, depression, and suicide during key lockdown periods, which suggest negative mental health effects. Regarding coping strategies, searches for Zoom, learning, books, exercise, prayer, religion, and meditation increased, together with searches for addiction and marijuana. These results indicate the types of programs health administrators and policymakers can implement during lockdown periods to help local mental health communities, particularly among island communities.

Epidemiology of Untreated Psychoses in 3 Diverse Settings in the Global South: The International Research Program on Psychotic Disorders in Diverse Settings (INTREPID II).

Importance: Less than 10% of research on psychotic disorders has been conducted in settings in the Global South, which refers broadly to the regions of Latin America, Asia, Africa, and Oceania. There is a lack of basic epidemiological data on the distribution of and risks for psychoses that can inform the development of services in many parts of the world. Objective: To compare demographic and clinical profiles of cohorts of cases and rates of untreated psychoses (proxy for incidence) across and within 3 economically and socially diverse settings in the Global South. Two hypotheses were tested: (1) demographic and clinical profiles of cases with an untreated psychotic disorder vary across setting and (2) rates of untreated psychotic disorders vary across and within setting by clinical and demographic group. Design, Setting, and Participants: The International Research Program on Psychotic Disorders in Diverse Settings (INTREPID II) comprises incidence, case-control, and cohort studies of untreated psychoses in catchment areas in 3 countries in the Global South: Kancheepuram District, India; Ibadan, Nigeria; and northern Trinidad. Participants were individuals with an untreated psychotic disorder. This incidence study was conducted from May 1, 2018, to July 31, 2020. In each setting, comprehensive systems were implemented to identify and assess all individuals with an untreated psychosis during a 2-year period. Data were analyzed from January 1 to May 1, 2022. Main Outcomes and Measures: The presence of an untreated psychotic disorder, assessed using the Schedules for Clinical Assessment in Neuropsychiatry, which incorporate the Present State Examination. Results: Identified were a total of 1038 cases, including 64 through leakage studies (Kancheepuram: 268; median [IQR] age, 42 [33-50] years; 154 women [57.5%]; 114 men [42.5%]; Ibadan: 196; median [IQR] age, 34 [26-41] years; 93 women [47.4%]; 103 men [52.6%]; Trinidad: 574; median [IQR] age, 30 [23-40] years; 235 women [40.9%]; 339 men [59.1%]). Marked variations were found across and within settings in the sex, age, and clinical profiles of cases (eg, lower percentage of men, older age at onset, longer duration of psychosis, and lower percentage of affective psychosis in Kancheepuram compared with Ibadan and Trinidad) and in rates of untreated psychosis. Age- and sex-standardized rates of untreated psychoses were approximately 3 times higher in Trinidad (59.1/100 000 person-years; 95% CI, 54.2-64.0) compared with Kancheepuram (20.7/100 000 person-years; 95% CI, 18.2-23.2) and Ibadan (14.4/100 000 person-years; 95% CI, 12.3-16.5). In Trinidad, rates were approximately 2 times higher in the African Trinidadian population (85.4/100 000 person-years; 95% CI, 76.0-94.9) compared with the Indian Trinidadian (43.9/100 000 person-years; 95% CI, 35.7-52.2) and mixed populations (50.7/100 000 person-years; 95% CI, 42.0-59.5). Conclusions and Relevance: This analysis adds to research that suggests that core aspects of psychosis vary by historic, economic, and social context, with far-reaching implications for understanding and treatment of psychoses globally.

Life events and psychosis: case-control study from India, Nigeria, and Trinidad and Tobago.

BACKGROUND: There is evidence of an association between life events and psychosis in Europe, North America and Australasia, but few studies have examined this association in the rest of the world. AIMS: To test the association between exposure to life events and psychosis in catchment areas in India, Nigeria, and Trinidad and Tobago. METHOD: We conducted a population-based, matched case-control study of 194 participants in India, Nigeria, and Trinidad and Tobago. Cases were recruited through comprehensive population-based, case-finding strategies. The Harvard Trauma Questionnaire was used to measure life events. The Screening Schedule for Psychosis was used to screen for psychotic symptoms. The association between psychosis and having experienced life events (experienced or witnessed) was estimated by conditional logistic regression. RESULTS: There was no overall evidence of an association between psychosis and having experienced or witnessed life events (adjusted odds ratio 1.19, 95% CI 0.62-2.28). We found evidence of effect modification by site (P = 0.002), with stronger evidence of an association in India (adjusted odds ratio 1.56, 95% CI 1.03-2.34), inconclusive evidence in Nigeria (adjusted odds ratio 1.17, 95% CI 0.95-1.45) and evidence of an inverse association in Trinidad and Tobago (adjusted odds ratio 0.66, 95% CI 0.44-0.97). CONCLUSIONS: This study found no overall evidence of an association between witnessing or experiencing life events and psychotic disorder across three culturally and economically diverse countries. There was preliminary evidence that the association varies between settings.

Insight, grey matter and cognitive function in first-onset psychosis.

BACKGROUND: Several studies have suggested that neuropsychological and structural brain deficits are implicated in poor insight. Few insight studies however have combined neurocognitive and structural neuroanatomical measures. AIMS: Focusing on the ability to relabel psychotic symptoms as pathological, we examined insight, brain structure and neurocognition in first-onset psychosis. METHOD: Voxel-based magnetic resonance imaging data were acquired from 82 individuals with psychosis and 91 controls assessed with a brief neuropsychological test battery. Insight was measured using the Schedule for the Assessment of Insight. RESULTS: The principal analysis showed reduced general neuropsychological function was linked to poor symptom relabelling ability. A subsequent between-psychosis group analysis found those with no symptom relabelling ability had significant global and regional grey matter deficits primarily located at the posterior cingulate gyrus and right precuneus/cuneus. CONCLUSIONS: The cingulate gyrus (as part of a midline cortical system) along with right hemisphere regions may be involved in illness and symptom self-appraisal in first-onset psychosis.

INTREPID II: protocol for a multistudy programme of research on untreated psychosis in India, Nigeria and Trinidad.

INTRODUCTION: There are few robust and directly comparable studies of the epidemiology of psychotic disorders in the Global South. INTREPID II is designed to investigate variations in untreated psychotic disorders in the Global South in (1) incidence and presentation (2) 2-year course and outcome, (3) help-seeking and impact, and (4) physical health. METHODS: INTREPID II is a programme of research incorporating incidence, case-control and cohort studies of psychoses in contiguous urban and rural areas in India, Nigeria and Trinidad. In each country, the target samples are 240 untreated cases with a psychotic disorder, 240 age-matched, sex-matched and neighbourhood-matched controls, and 240 relatives or caregivers. Participants will be followed, in the first instance, for 2 years. In each setting, we have developed and are employing comprehensive case-finding methods to ensure cohorts are representative of the target populations. Using methods developed during pilot work, extensive data are being collected at baseline and 2-year follow-up across several domains: clinical, social, help-seeking and impact, and biological. ETHICS AND DISSEMINATION: Informed consent is sought, and participants are free to withdraw from the study at any time. Participants are referred to mental health services if not already in contact with these and emergency treatment arranged where necessary. All data collected are confidential, except when a participant presents a serious risk to either themselves or others. This programme has been approved by ethical review boards at all participating centres. Findings will be disseminated through international conferences, publications in international journals, and through local events for key stakeholders.

Gender differences in the association between childhood abuse and psychosis.

BACKGROUND: Studies demonstrating an association between childhood trauma and psychosis in adulthood have not systematically explored gender differences. AIMS: To investigate gender differences in the prevalence of childhood sexual and physical abuse among people with psychosis in comparison with healthy controls. METHOD: The Childhood Experiences of Care and Abuse Questionnaire was completed to elicit experiences of sexual and physical abuse during childhood in first-episode psychosis cases and population-based controls. RESULTS: Among women, those in the cases group were twice as likely to report either physical or sexual abuse compared with controls following adjustment for all confounders. In particular, the effect of physical abuse in women was stronger and more robust than that for sexual abuse. A similar trend was found for psychotic-like experiences in the female control group. No association was found in men. CONCLUSIONS: Reports of severe childhood physical or sexual abuse were associated with psychosis in women but not in men.

Migration, ethnicity and psychoses: evidence, models and future directions.

There is a large body of research reporting high rates of psychotic disorders among many migrant and minority ethnic groups, particularly in Northern Europe. In the context of increasing migration and consequent cultural diversity in many places worldwide, these findings are a major social and public health concern. In this paper, we take stock of the current state of the art, reviewing evidence on variations in rates of psychoses and putative explanations, including relevant theories and models. We discuss in particular: a) the wide variation in reported rates of psychotic disorders by ethnic group, and b) the evidence implicating social risks to explain this variation, at ecological and individual levels. We go on to set out our proposed socio-developmental model, that posits greater exposure to systemic social risks over the life course, particularly those involving threat, hostility and violence, to explain high rates of psychoses in some migrant and minority ethnic groups. Based on this analysis, the challenge of addressing this social and public health issue needs to be met at multiple levels, including social policy, community initiatives, and mental health service reform.

Sexually dimorphic changes in the amygdala in relation to delusional beliefs in first episode psychosis.

BACKGROUND: Few attempts have been made to examine the relationship between amygdala abnormalities and specific symptoms in psychosis. The present study explored the relationship between amygdala morphology and mood congruent and mood incongruent delusional beliefs. METHODS: Amygdala volumes were measured in 43 patients presenting with delusional beliefs in the context of their first episode of psychosis and 43 healthy volunteers matched for age and gender. RESULTS: Left-greater-than-right-asymmetry of the amygdala varied as a function of gender and mood congruence of delusional beliefs, due to asymmetrical enlargement of the left amygdala in women presenting with predominantly mood incongruent delusions. However, there was no difference in amygdala volumes across groups. CONCLUSIONS: Amygdala abnormalities in women may be associated with aberrant emotional processing that could contribute to the development of mood incongruent delusional beliefs. Sexually dimorphic changes in the amygdala may contribute to differential phenotypic illness expression in men and women.

Heterogeneity in incidence rates of schizophrenia and other psychotic syndromes: findings from the 3-center AeSOP study.

CONTEXT: Convention suggests uniformity of incidence of schizophrenia and other psychoses; variation would have implications for their causes and biological characteristics. OBJECTIVE: To investigate variability in the incidence of psychotic syndromes in terms of place, ethnicity, age, and sex. DESIGN: Three-center, prospective, comprehensive survey of clinically relevant first-onset psychotic syndromes over a 2-year period (1997-1999). Census data provided the denominator. SETTING: Southeast London, Nottingham, and Bristol, England. PARTICIPANTS: One million six hundred thousand person-years yielded 568 subjects aged 16 to 64 years with clinically relevant psychotic syndromes. MAIN OUTCOME MEASURES: The World Health Organization Psychosis Screen and the Schedules for Clinical Assessment in Neuropsychiatry to classify, blind to ethnicity, all DSM-IV psychotic syndromes and the subclasses of schizophrenia, other nonaffective disorders, affective disorders, and substance-induced psychosis. RESULTS: All syndromes showed a characteristic age distribution. Schizophrenia was significantly more common in men (incidence rate ratio [IRR], 2.3 [95% confidence interval (CI), 1.7-3.1]); affective disorders occurred equally in men and women (IRR, 1.0 [95% CI, 0.7-1.3]). All psychoses were more common in the black and minority ethnic group (crude IRR, 3.6 [95% CI, 3.0-4.2]). Differences in age, sex, and study center accounted for approximately a quarter of this effect (adjusted IRR, 2.9 [95% CI, 2.4-3.5]) in each psychosis outcome. The age-sex standardized incidence rate for all psychoses was higher in Southeast London (IRR, 49.4 [95% CI, 43.6-55.3]) than Nottingham (IRR, 23.9 [95% CI, 20.6-27.2]) or Bristol (IRR, 20.4 [95% CI, 15.1-25.7]). Rates of all outcomes except affective disorders remained significantly higher in Southeast London when the model was expanded to control for ethnicity. CONCLUSIONS: There is significant and independent variation of incidence of schizophrenia and other psychoses in terms of sex, age, ethnicity, and place. This confirms that environmental effects at the individual, and perhaps neighborhood level, may interact together and with genetic factors in the etiology of psychosis.

Grey matter abnormalities in first-episode schizophrenia and affective psychosis.

BACKGROUND: Grey matter and other structural brain abnormalities are consistently reported in first-onset schizophrenia, but less is known about the extent of neuroanatomical changes in first-onset affective psychosis. AIMS: To determine which brain abnormalities are specific to (a) schizophrenia and (b) affective psychosis. METHOD: We obtained dual-echo (proton density/T2-weighted) magnetic resonance images and carried out voxel-based analysis on the images of 73 patients with first-episode psychosis (schizophrenia n=44, affective psychosis n=29) and 58 healthy controls. RESULTS: Both patients with schizophrenia and patients with affective psychosis had enlarged lateral and third ventricle volumes. Regional cortical grey matter reductions (including bilateral anterior cingulate gyrus, left insula and left fusiform gyrus) were evident in affective psychosis but not in schizophrenia, although patients with schizophrenia displayed decreased hippocampal grey matter and increased striatal grey matter at a more liberal statistical threshold. CONCLUSIONS: Both schizophrenia and affective psychosis are associated with volumetric abnormalities at the onset of frank psychosis, with some of these evident in common brain areas.

Supernatural versus medical: Responses to mental illness from undergraduate university students in Trinidad.

Background/Introduction: Perceptions about the aetiology of mental illness are likely to influence help-seeking behaviour. Understanding help-seeking behaviour will improve service provision and access. Therefore, this is likely to improve treatment outcomes. METHODS: We assessed the perceptions and help-seeking behaviours surrounding mental illness in a Trinidadian population of 158 tertiary-level students (136 female, 22 male; mean age 30) by analysing their responses to a questionnaire which asked for responses regarding a case vignette of a 25-year-old young woman exhibiting symptoms suggestive of schizophrenia. RESULTS: Of the respondents, 32.3% attributed the symptoms to supernatural causes. Specifically, 27.8% to someone doing her bad and 24.1% to evil spirits. In all, 77.2% of respondents indicated that mental illness was caused by medical problems and 63.3% to work stress. A minimum of 9.5% of the students therefore have dual perceptions regarding causation (77.2 + 32.3 = 109.5) Those who perceived causation to be supernatural said they would seek help from both medical ( p = .000) and supernatural ( p = .000) modalities. This also applied significantly to those who said the causation was medical, that is, seeking both religious intervention ( p = .000) and medical intervention (.000) as the first path in the health-seeking pathway. CONCLUSION: Dual help-seeking behaviour seems to be the functional result of an integration of religious and medical models of mental illness causation even in respondents who clearly identified only one of these as the likely cause of the illness behaviour.
