The Mental Health of Adult Irregular Migrants to Europe: A Systematic Review

The aim of this systematic review is to summarise the existing evidence on the mental health outcomes of adult irregular immigrants (IMs) to Europe. Database (MEDLINE, EMBASE, CINAHL, PsychINFO) searches were conducted according to PRISMA. The risk of bias was assessed using the Appraisal tool for Cross-Sectional Studies. The database searches yielded 2982 results. Eight cross-sectional studies from Western Europe were included, with 1201 participants. The prevalence of mental disorders varied between studies: depression from 8 to 86%; anxiety from 3.1 to 81%; and post-traumatic stress disorder (PTSD) from 3.4 to 57.6%. The studies had methodological flaws; in particular a risk of unrepresentative samples. There was methodological heterogeneity, therefore pooling of data, and direct comparisons were not possible. The majority of studies found higher rates of depression, anxiety and PTSD than previous estimates for the general population, and higher rates of depression and anxiety than previous estimates for other migrant groups.

Social Vulnerability and Mental Health Inequalities in the "Syndemic": Call for Action

Covid-19 is referred to as a "syndemic," i.e., the consequences of the disease are exacerbated by social and economic disparity. Poor housing, unstable work conditions, caste, class, race and gender based inequities and low incomes have a profound effect on mental health and wellbeing. Such disparities are increasing between, among and within countries and are exacerbated by human rights violations, in institution and in society, stigma and discrimination. Social capital can mediate health outcomes, through trust and reciprocity, political participation, and by mental health service systems, which can be coercive or more open to demand of emancipation and freedom. Societal inequalities affect especially vulnerable groups, and Covid itself had a wider impact on the most socially vulnerable and marginalized populations, suffering for structural discrimination and violence. There are complex relations among these social processes and domains, and mental health inequalities and disparity. Participation and engagement of citizens and community organizations is now required in order to achieve a radical transformation in mental health. A Local and Global Action Plan has been launched recently, by a coalition of organizations representing people with lived experience of mental health care; who use services; family members, mental health professionals, policy makers and researchers, such as the International Mental Health Collaborating Network, the World Federation for Mental Health, the World Association for Psychosocial Rehabilitation, the Global Alliance of Mental Illness Advocacy Networks (GAMIAN), The Mental Health Resource Hub in Chennai, India, The Movement for Global Mental Health (MGMH) and others. The Action Plan addresses the need for fundamental change by focusing on social determinants and achieving equity in mental health care. Equally the need for the politics of wellbeing has to be embedded in a system that places mental health within development and social justice paradigm, enhancing core human capabilities and contrasting discriminatory practices. These targets are for people and organizations to adopt locally within their communities and services, and also to indicate possible innovative solutions to Politics. This global endeavor may represent an alternative to the global mental discourse inspired by the traditional biomedical model.

Why Trieste matters

Trieste mental health service is considered as one of the best mental healthcare systems in the world. This service is now under threat from right-wing politicians in the local region. We argue that this is a threat to progressive community psychiatry beyond Trieste and Italy. It is important for us to join forces with international colleagues and organisations in the campaign to defend and preserve the current service model in Trieste.

Reducing coercion in mental healthcare

AIMS

To examine the extent and nature of coercive practices in mental healthcare and to consider the ethical, human rights challenges facing the current clinical practices in this area. We consider the epidemiology of coercion in mental health and appraise the efficacy of attempts to reduce coercion and make specific recommendations for making mental healthcare less coercive and more consensual.

METHODS

We identified references through searches of MEDLINE, EMBASE, PsycINFO and CINAHL Plus. Search was limited to articles published from January 1980 to May 2018. Searches were carried out using the terms mental health (admission or detain* or detention or coercion) and treatment (forcible or involuntary or seclusion or restraint). Articles published during this period were further identified through searches in the authors' personal files and Google Scholar. Articles resulting from searches and relevant references cited in those articles were reviewed. Articles and reviews of non-psychiatric population, children under 16 years, and those pertaining exclusively to people with dementia were excluded.

RESULTS

Coercion in its various guises is embedded in mental healthcare. There is very little research in this area and the absence of systematic and routinely collected data is a major barrier to research as well as understanding the nature of coercion and attempts to address this problem. Examples of good practice in this area are limited and there is hardly any evidence pertaining to the generalisability or sustainability of individual programmes. Based on the review, we make specific recommendations to reduce coercive care. Our contention is that this will require more than legislative tinkering and will necessitate a fundamental change in the culture of psychiatry. In particular, we must ensure that clinical practice never compromises people's human rights. It is ethically, clinically and legally necessary to address the problem of coercion and make mental healthcare more consensual.

CONCLUSION

All forms of coercive practices are inconsistent with human rights-based mental healthcare. This is global challenge that requires urgent action.

Mental Health Review Tribunals

Following the 1983 Mental Health Act, Mental Health Review Tribunals (MHRT) now provide the opportunity for patients to have their detention reviewed and give a right of appeal against compulsory hospital detention or guardianship (Bluglass, 1983).

Black people and psychiatry in the UK

Our aim in this paper is to examine the current practice of psychiatry in relation to race or ethnicity in England. The problems that European psychiatry has in relation to black people in a white and predominantly racist society and the responses to these from within the professional sphere are only one aspect of our current topic. We merely mention these to contextualise the problems black people experience as a result of institutional psychiatry. Our main aim in this paper is to articulate the oppression black people experience in relation to conventional psychiatry and to seek ways of confronting and changing this, very much as part of the larger, black struggle in the UK. We believe that the alternative that we propose, based on black experience of psychiatry, is equally valid in other contexts where questions of disadvantage and discrimination are the overriding themes. Although the theoretical basis of our work is grounded on issues such as inequality and structural oppression and the need to confront and change them, a detailed analysis of these topics is beyond the scope of this paper. Instead, we examine the practice of professional psychiatry in relation to black people in the UK and argue that the model that is imposed on us is antithetical to the interests of black minority groups. We also look at practical ways in which our community is beginning to organise in challenging such professional orthodoxy.

Institutional racism in British psychiatry

How racist is British psychiatry? Why does psychiatric practice in this country continue to discriminate against Irish, Black and Asian people? How do we, as a profession, respond to the charge of institutional racism, increasingly accepted as a major problem within British psychiatry?

Availability and acceptability of home treatment for acute psychiatric disorders

Aims and Methods

To ascertain current levels of access to home treatment for those with acute mental illness and future plans of trusts and purchasing authorities to provide such services. Also, to assess the attitudes of these organisations towards this form of treatment. A postal survey of all mental health trusts and purchasing authorities within the UK was carried out.

Results

One hundred and seventy-two trusts and 82 health authorities returned questionnaires, representing a response rate of 75% and 67% respectively. Only 27 (16%) of trusts provided home treatment but 58 (40%) had plans to do so. All health authorities and 97% of trusts were in favour of the principle of providing home treatment.

Clinical Implications

Despite the low levels of provision of home treatment trusts and health authorities were strongly in favourof it. There is likely to be a large increase in its availability over the next 12 months.

Global mental health in high-income countries

Over the past decade there have been significant efforts to scale-up mental health services in resource-poor countries. A number of cost-effective innovations have emerged as a result. At the same time, there is increasing concern in resource-rich countries about efficacy, efficiency and acceptability of mental health services. We consider two specific innovations used widely in low- and middle-income countries, task-sharing and a development model of mental healthcare, that we believe have the potential to address some of the current challenges facing mental health services in high-income countries.

Towards a more nuanced global mental health

The World Health Organization has made concerted efforts to scale up mental health services in low- and middle-income countries through the Mental Health Gap Action Programme (mhGAP) initiative. However, an overreliance on scaling up services based on those used in high-income countries may risk causing more harm than good.

Experiences of acute mental health care in an ethnically diverse inner city: qualitative interview study

PURPOSE

Ethnic inequalities in experiences of mental health care persist in the UK, although most evidence derives from in-patient settings. We aimed to explore service users' and carers' accounts of recent episodes of severe mental illness and of the care received in a multi-cultural inner city. We sought to examine factors impacting on these experiences, including whether and how users and carers felt that their experiences were mediated by ethnicity.

METHODS

Forty service users and thirteen carers were recruited following an acute psychotic episode using typical case sampling. In-depth interviews explored illness and treatment experiences. Ethnicity was allowed to emerge in participants' narratives and was prompted if necessary.

RESULTS

Ethnicity was not perceived to impact significantly on therapeutic relationships, and nor were there ethnic differences in care pathways, or in the roles of families and friends. Ethnic diversity was commonplace among both service users and mental health professionals. This was tolerated in community settings if efforts were made to ensure high-quality care. Home Treatment was rated highly, irrespective of service users' ethnicity. In-patient care was equally unpopular and was the one setting where ethnicity appeared to mediate unsatisfactory care experiences. These findings highlight the risks of generalising from reports of (dis)satisfaction with care based predominantly on in-patient experiences.

CONCLUSIONS

Home treatment was popular but hard to deliver in deprived surroundings and placed a strain on carers. Interventions to enhance community treatments in deprived areas are needed, along with remedial interventions to improve therapeutic relationships in hospital settings.

Care pathways for south Asian and white people with depressive and anxiety disorders in the community

BACKGROUND

South Asian people with common mental disorders are less likely to have their problems recognised by their general practitioner and have lower rates of uptake of psychiatric services compared to native born white people. Less consideration has been given to their understanding of their mental health problems, their use of alternative supports and the treatment they receive in primary care.

METHODS

A general population sample identified, using a semi-structured diagnostic interview, as having DSM-IIIR depressive or anxiety disorders was obtained. South Asian and white participants' appraisal of their mental health problems and their use of informal and formal assistance during the period they were unwell in the previous 6 months were compared.

RESULTS

There was no difference between south Asian and white people, either in what they understood to be the matter with them or in what they perceived to be the cause of their problems. No south Asian participants reported seeking help from lay or traditional healers, while white people more often discussed their problems with a relative or friend. Most south Asian people consulted their GP and this was significantly higher than for whites. However, only around half the people in both groups reported disclosing their problem to a GP and only one in ten received psychiatric medication or was referred to specialist psychiatric services.

CONCLUSIONS

Along with public education and GP training, the availability of appropriate and acceptable interventions for south Asian, and indeed white people, with common mental disorders consulting in primary care is key to ensuring that they gain access to necessary mental health care.

Characteristics of patients and patterns of psychiatric service use in ethnic minorities

BACKGROUND

The differential uptake of psychiatric services by ethnic minorities has been widely reported. Less attention has been given to comparisons of these patients and variations in the types of interventions they receive.

AIMS

To assess whether for people accessing psychiatric services in the UK, differences exist across ethnic groups both in their sociodemographic characteristics and patterns of mental health care utilisation.

METHODS

All adults resident in an inner city health district and using psychiatric services during a six-month period were identified. Demographic, clinical and service use data were collected from staff and records. These were compared across black Caribbean, Indian, Pakistani, Irish and white ethnic groups for two broad diagnostic categories: psychotic/bipolar and depressive/neurotic disorders.

RESULTS

There were significant differences between ethnic groups on most demographic variables in each of the diagnostic categories. There were variations in the level of contact with different mental health professionals. The only significant difference in the use of specific services was for those with psychotic/bipolar disorders, black Caribbean patients being more likely to be detained in hospital compulsorily.

CONCLUSIONS

Ethnic diversity both in the characteristics of patients and their patterns of psychiatric care should be addressed when planning and developing services.

Psychiatric morbidity in people born in Ireland

BACKGROUND

Irish immigrants are reported to be over-represented in psychiatric admission statistics for England when compared to native whites. This study examines whether this finding is sustained for users of psychiatric services as a whole and explicates the reasons for any differential uptake of mental health care by comparison with community morbidity rates in the same population.

METHODS

Demographic and clinical data were collected from staff concerning all adults living in a multiethnic inner-city health district and using mental health services during a 6-month period. A separate interview-based survey of private household residents in the same area was undertaken to ascertain the prevalence of psychiatric disorder in the community.

RESULTS

Psychiatric service use was found to be greater for Irish-born people compared to the remainder of the white population. However, this finding only persisted for alcohol use disorders, the rates for schizophrenic and affective disorders being comparable in the two groups. Access to psychiatric care was also similar both with respect to overall morbidity as well as for affective and alcohol use disorders, levels of service use being attributable to patterns of morbidity in the population rather than nosocomial factors.

CONCLUSIONS

The excess morbidity for alcohol use disorders reported in people born in Ireland is affirmed and the need for longitudinal and ethnographic research into this important public health issue emphasised.

Mental health care for Asian, black and white patients with non-affective psychoses: pathways to the psychiatric hospital, in-patient and after-care

BACKGROUND

This UK-based study compares the pathways to the psychiatric hospital and the provision of in-patient and after-care for Asian, black and white patients with non-affective psychoses.

METHODS

Two overlapping samples of 120 patients, 40 from each ethnic group, were drawn; one on admission and the other at discharge. In addition to socio-demographic data, details were obtained on the pathways to care and the in-patient episode. An assessment of needs and service provision was undertaken 3 months post-discharge. Patient satisfaction was ascertained at each stage.

RESULTS

Asian and especially black patients experienced more complex pathways and had higher levels of both involvement with the police and compulsory detention than their white counterparts. They were less likely to perceive themselves as having a psychiatric problem or as needing to go into hospital and expressed less satisfaction with the admission process. Black patients, as compared to Asian but especially white patients, were more often detained in hospital against their will, confined to the ward and treated within a secure environment. However, there were few differences in satisfaction with hospital care. Likewise, perceptions of unmet need, provision of after-care and satisfaction with services were similar across the ethnic groups.

CONCLUSIONS

The implications of these findings are discussed. The potential of early intervention programmes and home treatment services to address the ethnic differentials identified in this study merit consideration.

Pathways to care for alcohol use disorders

BACKGROUND

The aim of the present study was to examine access to care for people with alcohol use disorders.

METHOD

An alcohol screening questionnaire was completed by 444 respondents in a community survey. During a designated week, 1009 patients presenting in primary care were assessed by their doctor and 773 of these completed the same questionnaire. Over a six month period 223 people with alcohol use disorders were identified using specialist addiction and psychiatric services, of whom 58 were admitted to hospital. One month prevalence rates of alcohol morbidity were determined for people aged between 16 and 64 years at all five levels in the pathways to care model.

RESULTS

Around half the people with alcohol morbidity in the community never consulted their general practitioner and of those who did only half had their problem identified. Case recognition was particularly poor for women, young people and Asians. The main filter to people accessing specialist services came at the point of referral from primary care. This was especially marked for young people and for ethnic minorities.

CONCLUSIONS

Strategies are required to improve the identification and treatment of alcohol morbidity in primary care. Deficits in access to specialist services for women, young people and ethnic minorities need to be addressed.

Determinants of general practitioner recognition of psychological problems in a multi-ethnic inner-city health district

BACKGROUND

With few exceptions, evaluation of the capacity of general practitioners (GPs) to recognise psychiatric disorder in their patients has failed to consider the role of ethnic diversity in the consultation process and whether such knowledge can improve understanding of the degree to which psychiatric morbidity is recognised within GP settings.

METHODS

This research was completed in five general practices representative of all those within an inner-city health district. Psychiatric morbidity in patients consecutively attending the practices was then assessed using the General Health Questionnaire; in addition, GPs were asked to complete a checklist of current problems identified during each consultation.

RESULTS

Analysis suggested that Asian and Black patients were less likely than White patients to have psychological problems identified; that social problems and a psychiatric history facilitated recognition; and that current physical illness hindered recognition.

CONCLUSIONS

GP recognition of psychological problems varies according to patient ethnicity but can be substantially masked by both the physical and social circumstances of patients at consultation.

A comparison of the socio-demographic and clinical characteristics of private household and communal establishment residents in a multi-ethnic inner-city area

This study compares the socio-demographic, physical and psychiatric profiles of representative samples of adults resident in communal establishments (n = 170) with those living in private households (n = 544) in a deprived multi-ethnic inner-city health district. Respondents were interviewed about their psychiatric and physical health as well as their early life experiences, close personal relationships, experiences of police contact and episodes of deliberate self-harm. Communal establishment residents were more likely to be single, white men and to be out of work than those in the private household sample. They typically left school at an earlier age, had a more disrupted upbringing, were less likely to have close personal relationships and reported more contact with the police. Both physical and psychiatric morbidity were substantially higher in the communal establishment residents than among those living in private households (especially for psychotic disorders). In contrast to these findings, comparisons between communal establishment residents with and without mental health problems revealed few differences. Our data highlight the extensive needs of those living in communal establishments and the need for a wide range of agencies to co-ordinate their efforts effectively if services to this population are to be effective.

Affective disorders among women in the general population and among those referred to psychiatrists. Clinical features and demographic correlates

In a study comparing depressive disorders detected in a field survey (n = 90) with patients referred to a specialist treatment setting (n = 63), the clinical features and demographic correlates of 'cases' of affective disorders proved to be similar. However, those in treatment settings appeared to have more people achieving definite case status. Hospital-referred cases were also more likely than community cases to be older and single, and this difference persisted even after controlling for chronicity of symptoms.

Self-esteem, life stress and psychiatric disorder

Using a special subsample from a survey of women in Edinburgh investigations were carried out into (a) which types of life event are associated with lowered self-esteem; (b) the role of life events and self-esteem in onset of psychiatric disorder; and (c) the additional significance of prior psychiatric consultation in determining onset. Stressors involving impaired relationships with others were the only ones clearly associated with lowered self-esteem. Minor psychiatric illness was predicted by stress of uncertain outcome, and, to a lesser extent, by impaired relationship stress. Onset of major depression was best predicted by an interaction between total stress experienced and low self-esteem. There was evidence that such onset involves a pre-existing low level of self-esteem on which life stress impinges, rather than life stress generating low self-esteem and then onset. A small group of subjects characterised by low self-esteem, prior psychiatric consultation and maladaptive coping seemed to be fluctuating in and out of psychiatric illness irrespective of stress.

Specificity of the salivary cortisol dexamethasone suppression test across psychiatric diagnoses

One hundred forty-eight psychiatric inpatients, 12 outpatients, and 17 normal controls were given the 1.0-mg overnight Dexamethasone Suppression Test (DST), with salivary cortisol concentrations being measured as the dependent variable. Based on the Structured Clinical Interview for DSM-III, the patients were diagnosed as having major depression with melancholia (n = 21), nonmelancholic major depression (n = 50), mania (n = 15), schizophrenia (n = 32), dementia (n = 6), substance dependence/abuse n = 18), and miscellaneous (n = 18). Neither the melancholic major depressives nor the entire group of major depressives had significantly higher salivary cortisol pre- or postdexamethasone as compared with all the other patients combined, nor did the melancholic patients have significantly higher cortisol than the nonmelancholic depressives. The inpatients as a group had significantly higher pre- and postdexamethasone cortisol values than the normal controls; cortisol values for the outpatients were intermediate between these two groups. Illness severity (in the depressives), length of time in hospital before the DST, and medication regimen were all unrelated to DST outcome. Thus, in this study, the salivary cortisol DST showed little clinical utility in discriminating major depressives with and without melancholia from other patients with a broad range of psychiatric diagnoses. The test did distinguish between hospitalized psychiatric patients and normal control subjects and between depressed inpatients and depressed outpatients, indicating that hospitalization-related variables contributed to DST outcome.

Hospital-treated and general-population morbidity from affective disorders. Comparison of prevalence and inception rates

In this study, we compare the rates of psychiatric disorders found among women in a random sample of the general population with those of patients referred to specialist services. Both these groups were drawn from the same geographical area. The ratio of prevalence rates is less than the ratio between inception rates in the two groups. When only those with affective disorders were considered, the results revealed that the point prevalence in the treated-disorders group was only 1% of the community-group prevalence, while the inception into care in the former group was nearly 6% of that in the latter. Single women and older women were over-represented in the hospital sample.

Self-appraisal, anxiety and depression in women. A prospective enquiry

Depressive illness is known to be associated with low self-evaluation, but it has been suggested that there may be a reciprocal connection as well, such that low self-appraisal (in the absence of illness) makes the subsequent onset of depression more likely. A prospective study, using a community sample of 376 women, provided data about clinical state over a period of 18 months, and self-appraisal questionnaire scores were determined on two occasions separated by 6 months. There was no evidence that low self-evaluation predicted future episodes of depressive illness, except in women who reported previous psychological episodes for which they had sought medical help, and, even for those with previous episodes, much of the predictive power of low self-esteem was accounted for by individuals who were subsequently recognised to have been in the early stages of illness. Conversely, there was little evidence that prior episodes predicted future illness in people with high self-esteem. One explanation of the findings is that recurrent episodes of illness cause progressive impairment of self-appraisal, but other possibilities are also considered. Women who had recovered from illnesses detected at the first interview still had significantly less self-confidence 6 months later than those who were well throughout.

Life events and other factors implicated in onset and in remission of psychiatric illness in women

Life stressors for 574 Edinburgh women were assessed for uncertain outcome, impaired relationships and other characteristics. Thirteen weeks were covered either with no illness present or before a transient episode of Research Diagnostic Criteria (RDC)-defined anxiety/depression (duration less than 13 weeks) or before a longer episode or before illness remission or during continuing illness. Exploratory analysis suggested that stressors of uncertain outcome preceded longer illness onset. Impaired relationships went with continuing illness. Stressors with neither of these, and with fewer than two other characteristics, preceded transient illness. Remaining stressors predicted remission, as did ending of long-term difficulties. Self-esteem, support, coping, previous illness and marital status also discriminated between the groups.

The epidemiology of life events and long-term difficulties, with some reflections on the concept of independence

A total of 576 women aged 18-65, drawn from an area in Edinburgh, were interviewed. Data on life events and long-term difficulties over a six-month period prior to interview were gathered and classified according to area of life, the Bedford system, the Edinburgh system, and the independence of the event or difficulty from the subject's own actions. The highest rates of Bedford system 'provoking' situations were found in the working class, among those not employed, among women with three or more children under 14, and in the separated, divorced, widowed or cohabitating group. Similar findings emerged for hopeless situations involving choice or loss. Dependent situations were four times more common in the youngest group than the oldest, and showed a high rate among those divorced, separated, widowed, or cohabiting. It is suggested that both dependent and independent life situations should be studied.

DSM-III melancholia: do the criteria accurately and reliably distinguish endogenous pattern depression?

The Structured Clinical Interview for DSM-III (SCID), Newcastle Endogenous/Reactive Index, Feinberg-Carroll Discriminant Index, and Hamilton Depression Scale were used to assess 70 depressed patients in order to determine similarities and differences in symptom structure and severity in those patients with and without endogenous/melancholic depression. All patients with melancholia according to DSM-III had definite endogenous major depression by the Research Diagnostic Criteria (RDC), but only 20 out of 35 patients with RDC definite endogenous depression were DSM-III melancholic. There was a greater difference in symptom pattern between those patients with definite endogenous depression and those with probable or non-endogenous depression than there was between the melancholic and non-melancholic definite endogenous depressives. A prerequisite for the valid delineation of a nosological category is the establishment of good reliability for diagnostic criteria. Using SCID ratings of audiotaped interviews of 9 patients (5 with major depression), the 8 raters in this study achieved a kappa coefficient of 0.79, suggesting that the use of a structured interview can improve the reliability of DSM-III diagnoses. Interrater reliabilities for most of the individual DSM-III major depressive episode and melancholia items were reasonable, but some were low. The low reliabilities could be improved by redefinition of the items to reduce ambiguity and by development of a SCID glossary.

Self-esteem, vulnerability and psychiatric disorder in the community

One hypothesis concerning the nature of the link between negative self-appraisal and certain psychological disorders is that low self-esteem may be a consequence of both early and current experiences, and may predispose to breakdown. An alternative view is that the negative self-concept is only to be found in the presence of illness, which is the primary cause. Results are reported from a community survey, confirming the influence of certain biographical factors on self-esteem in the absence of illness, whereas other factors appear to operate only after the onset of illness. Anxiety as well as depression, has effects on self-esteem.

Psychiatric morbidity in two matched community samples: a comparison of rates and risks in Edinburgh and St. Louis

The use of different diagnostic classifications of psychiatric disorder in the United States and the United Kingdom, together with associated changes in the operational definitions of disorder, has placed additional barriers in the way of U.S./U.K. comparative studies. However, the parallel development of two general population studies, one in Edinburgh and one in St. Louis, MO, has enabled a comparative analysis with limited objectives, to be undertaken. This paper presents results based upon matched samples of women from these studies. The findings revealed current overall prevalence, and the socio-demographic determinants of prevalence, to be similar in the two city samples. The results additionally indicate the consequence of applying diagnostic criteria appropriate to different ranges of psychiatric syndromes for the estimation of prevalence in general population samples.

Affective disorder amongst women in the general population: a longitudinal study

This paper reports upon a longitudinal general population survey of psychiatric disorder among a sample of women in Edinburgh. The course and outcome of the identified disorders, defined according to the RDC, are described. In addition the report documents the consequence, for the description of episodes, of adopting a diagnostic scheme which embodies hierarchical and inter-episode interval rules. Estimates of disease rates per year revealed a period prevalence of RDC disorder of 25.2% (17.6% depressive and 7.6% anxiety disorder) and an RDC new episode inception rate of 12.6%. In spite of the evident nontrivial nature of these conditions, and of the extent to which they were found to endure, contact with the psychiatric services was found to be minimal.

Life events and the onset of affective disorder. A longitudinal general population study

This paper examines the relationship between life events (ascertained by the Bedford College method) and the onset of affective disorder (defined according to the RDC scheme) in a longitudinal general population survey of women. Fall-off in the reporting of minor events is examined and discussed. Event rates, proportions of women challenged by events, and measures of the risk of RDC disorder associated with the experience of particular events are reported. The results based upon data from an initial interview were largely consistent with those based upon follow-up data, and underpinned earlier work. For both data sets, major difficulties were associated with illness onset. Severe dependent events showed stronger effects than severe independent events but both categories were rare. New substantive findings arising from short-term general population event research are unlikely.

Maladaptive coping reactions to stress. A study of illness inception

Eleven ways in which people might react to life stress were studied in a sample of 576 Edinburgh women. For each item the subjects were asked whether they had reacted that way in general in the past 6 months and whether they had reacted in that way in response to any specific life stresses they had experienced. Being angry with oneself, being angry with others, rumination, use of alcohol, and use of tobacco all discriminated between those who were well and those who were psychiatrically ill at first interview and these items were formed into a 6-point scale of maladaptive reaction, based largely on specific response. The researchers conducted a follow-up analysis of 306 women who were well at first interview, 35 of whom suffered a psychiatric illness episode (23 depression, 12 anxiety) within the subsequent year. Maladaptive reaction at interview one predicted later illness inception, even after taking life stress into account. Several extraneous variables were considered, none of which could explain this effect. Maladaptive reaction seemed sometimes to lead to illness even when there was only minimal later life stress. Attempts to find coping reactions which afford protection against illness inception were unsuccessful.

Definitions of psychiatric syndromes--comparison in hospital patients and general population

Four sets of commonly used 'operational definitions' of psychiatric disorders were applied to clinical information, obtained on the basis of semi-structured interviews with samples of hospital in-patients, out-patients, and general population. The agreement among them in defining 'cases' and in assigning specific diagnostic categories was examined. There was considerable variation among the diagnostic systems in distinguishing between 'cases' and 'non-cases' and in identifying sub-groups of cases as having specific diagnoses. Comparison of operationally defined syndrome categories with diagnoses assigned by clinicians also showed much disagreement.

Pre- and post-dexamethasone salivary cortisol concentrations in major depression

Seventy patients fulfilling DSM-III criteria for major depression were given the 1.0 mg overnight dexamethasone suppression test, with salivary cortisol concentrations being measured as the dependent variable. Using both the DSM-III and the Research Diagnostic Criteria, we categorized the patients into four groups based on increasing frequency of endogenous symptomatology. Among these four groups there were no significant differences in salivary cortisol concentrations either before dexamethasone or eight, 16, and 24 h after dexamethasone. Similarly, there were no significant differences among the groups in either the ratios of post- to pre-dexamethasone salivary cortisol or the frequencies of positive tests based on several criterion levels of cortisol for the three post-dexamethasone samples. Multiple regression analyses indicated that the Hamilton depression rating scale item "somatic anxiety" was significantly negatively related to post-dexamethasone cortisol concentrations. We conclude that, for our sample of major depressives, the salivary cortisol dexamethasone suppression test showed no utility as a laboratory correlate of depressive episodes with endogenous features.

Dexamethasone suppression test in depression: association with duration of illness

Plasma cortisol response to 1 mg dexamethasone suppression test was investigated in 37 patients with primary major depressive illness. Non-suppression of plasma cortisol was found in 14 of 37 (38%) patients. Duration of the index episode of illness was significantly shorter in the non-suppressors (11.1 +/- 9.1 weeks) than in the suppressors (29.7 +/- 25.6 weeks). The two groups were not distinguished by age, sex, polarity or severity of depressive symptoms. Eighty per cent of the non-suppressors (4/5) and 57% of the suppressors (8/14) had severe life events or major difficulties in the 6 months preceding the onset of illness, but this difference failed to reach statistical significance.

Recurrence of affective illness after withdrawal of long-term lithium treatment

Clinical outcome following discontinuation of long-term maintenance therapy with lithium and manic-depressive patients was studied. Although the majority showed recurrence of affective episodes, the relapses tended to be spread over a period of months. There was no evidence of immediate and inevitable "rebound" of psychotic episodes following lithium withdrawal. This finding is discussed in the light of results from other lithium discontinuation studies.

Psychiatric disorder in women from an Edinburgh community: associations with demographic factors

The prevalence of psychiatric disorder was determined according to alternative diagnostic criteria in a random sample of 576 women from an Edinburgh community. Whichever diagnostic system was applied, significantly higher rates of disorder were found among the working class, the unemployed and women who were divorced, widowed, separated or cohabiting; in the subgroup of women who met all these conditions, up to half were found to satisfy the diagnostic criteria. The observed prevalence estimates can be explained as the effects of each demographic factor acting independently, no interaction effects being needed. Our results are discussed in relation to the findings of others, and in terms of the statistical issues involved.
