Long-term follow-up of schizophrenia in 16 countries. A description of the International Study of Schizophrenia conducted by the World Health Organization.

An unexpected finding of the International Pilot Study of Schizophrenia, launched by the World Health Organization (WHO) in 1967, was that patients in countries outside Europe and the United States have a more favourable short- and medium-term course of the disease than those seen in developed countries. Since then, WHO has intensified its schizophrenia research programme and has initiated a set of international studies that have confirmed these initial findings and explored possible reasons for such differences in the course and outcome of schizophrenia. While such work has provided important findings and has generated additional pertinent hypotheses, it did not explain the differences in outcome. The present paper describes a new initiative in which approximately 2500 subjects involved in previous WHO multicentre schizophrenia studies are being followed up for between 15 and 25 years after initial examination. Nineteen research centres in 16 countries are taking part in this work. The research methodology is described.

Progress toward achieving a common language in psychiatry. Results from the field trial of the clinical guidelines accompanying the WHO classification of mental and behavioral disorders in ICD-10.

In preparing for the 10th revision of the International Classification of Diseases (ICD-10), the Division of Mental Health of the World Health Organization organized an international field trial to help evaluate draft clinical descriptions and diagnostic guidelines that were produced to facilitate use of the chapter dealing with mental and behavioral disorders. These clinical guidelines were prepared in equivalent versions in most of the world's widely spoken languages. The field trial aimed to obtain data that would help in assessing whether the classification fits the diagnoses made in different countries, whether it is easy to use, and whether psychiatrists after a short period of familiarization with the classification can reach agreement about their diagnoses and classification. The field trial was carried out at 112 clinical centers in 39 countries by 711 clinicians who conducted 15,302 individual assessments. The trial included joint clinical assessments of patients and case history exercises. The results of the joint assessment part of the trial are reported here. Most clinicians reported that the draft document was easy to use and that the classification provided a good fit for the vast majority of the clinical conditions encountered. While interrater reliability was satisfactory for most categories, some (for example, those dealing with personality disorders) were somewhat difficult to use, and reliability of assignment for those was lower. The trial demonstrated that the ICD-10 chapter dealing with mental and behavioral disorders is on the whole suitable for general use. It provided valuable indications about changes needed for subsequent versions and demonstrated the feasibility of large-scale international research on classification and diagnosis in psychiatry.

The epidemiology of suicidal behaviour: a review of three continents.

Suicidal behaviour includes suicidal ideation, parasuicide or attempted suicide, and completed suicide. Assessment and recording of suicidal ideation and parasuicide is most difficult, and the first internationally comparable data on parasuicide are expected from an ongoing WHO-coordinated study in 15 European centres. On the other hand, about 50% of WHO's 186 Member States report suicide as part of their mortality statistics. Although there is no uniformity in definitions of suicidal acts nor in recording procedures, certain patterns of suicidal behaviour emerge across countries. The incidence of parasuicide is 10 to 20 times higher than that of completed suicide; the male/female ratios for suicide and attempted suicide are reciprocal: 3 times more women then men commit parasuicide, while in most countries about 3 times more men than women commit suicide. From a public health point of view, suicide in adolescents and young adults is particularly important: suicide in adolescence and young adulthood ranks among the 5 leading causes of death in many countries. There have been clear and dramatic increases in suicide rates in most WHO Member States which report mortality statistics to the Organization, especially among young men. Suicide in old age, particularly among men, is about 2 to 3 times more frequent than in younger age groups. Although it is not surprising that mortality increases with age, death by suicide is considered in most cultures and by most people as particularly deplorable and unnecessary. The epidemiological analysis of suicidal behaviour globally does not identify clear-cut risk factors amenable to preventive programmes. It does, however, pinpoint countries with "unusual" suicide patterns which, it is hoped, will initiate country-specific research into causes of such behaviour. Particularly promising, from the perspective of suicide prevention, seems to be research into the methods of suicide, and the impact of publicity of suicidal acts, as it has been shown repeatedly that restricting access to the prevailing method of suicide in a country will decrease suicide rates, while wide publicity about suicidal acts will increase them.

A triaxial classification of health problems presenting in primary health care. A World Health Organization multi-centre study.

Over the past two decades, research in a variety of countries and settings has revealed the extent to which psychological morbidity and social problems constitute an important proportion of primary health care contacts, either in their own right or in association with physical ill-health. The development of appropriate responses, medical and non-medical, to such problems is, in part, hindered by the relatively low level of awareness concerning the significance of such problems and by currently inappropriate methods of describing and classifying health care problems in the primary care setting. There is a pressing need for an appropriate, relatively simple and flexible classification or list of problems presenting in primary care. This study describes the development, under WHO auspices and in an international setting, of a triaxial classification of health problems and the testing and modification of the classification by means of an international case vignette rating exercise. A psychological problem list and a social problem list, together with detailed glossaries, suitably modified in the light of experience derived from the study, are described, and proposals enumerated of possible ways in which these lists might be further developed and used in research and clinical undertakings in primary care.

Characteristics of depressive patients contacting psychiatric services in four cultures. A report from the who collaborative study on the assessment of depressive disorders.

The paper is a report on results obtained in the course of a multi-centre international study on depressive disorders in four countries, which was sponsored and co-ordinated by the World Health Organization. A screen form was developed and tested in order to select depressive patients among psychiatric in-patient and out-patient populations. The patients selected in this way were assessed clinically by experienced investigators using the WHO schedule for Standardized Assessment of Depressive Disorders (SADD). A total of 53 patients were evaluated in the five research centres, and the data were utilized in uni- and multivariate statistical analyses aiming to establish whether similar cases of depression could be found in different cultures, to describe their characteristics and to ascertain the extent to which diagnostic concepts and classification categories could be applied in different settings. The results point to a considerable degree of similarity in depressive symptomatology across the cultures if particular selection criteria are applied, and suggest that broad diagnostic groupings such as 'endogenous' and 'psychogenic' depressions could be used consistently by clinicians working in different cultures.

WHO collaborative study: assessment of depressive disorders.

In the context of an ongoing WHO research programme in depression, a total of 573 patients consulting psychiatrists in Canada, Iran, Japan and Switzerland were assessed with the WHO/SADD schedule which proved to be a simple and reliable instrument for standardized recording of clinical data. The results indicated that the "average" depressive patients seeking care in culturally different settings have many clinical features in common. A screening instrument, developed in the same study, has been shown to be effective in selecting depressive patients among in- and out-patient populations.

Reliability of the AMDP-system. A preliminary report on a multicentre exercise on the reliability of psychopathological assessment.

The AMDP-System is a documentation system for psychiatric data widely in use in the German-speaking countries. A summary of results of a multicentered study of interrater agreement of the Psychopathology Scale is presented. A new index of rater agreement was tested and the notion is discussed that the judgement of the presence and the absence of a symptom are two different processes with different reliability.
