Objective: To present the one-year prevalence of 14 psychiatric disorders in a community sample of Ontarians aged 15 to 64 years. Method: Data on psychiatric disorders were collected on 9953 respondents using the University of Michigan revision of the Composite International Diagnostic Interview (UM-CIDI). DSM-III-R criteria were used to define the psychiatric disorders. Results: Almost 1 in 5 Ontarians (18.6%) had one or more of the disorders measured in the survey. Among 15- to 24-year-olds, 1 in 4 was affected. The distribution of individual disorders varied by sex and age. Conclusion: Because of the immense burden of suffering associated with psychiatric disorders, clinical and research efforts in this area should receive high priority within the health budget.

This study examined the relationship between patterns of alcohol consumption, including problem drinking, and psychiatric disorders in the general population. The paper utilizes data on 8,116 adults age 15–64 living in households who were interviewed for the Ontario Health Survey and the Mental Health Supplement. The University of Michigan Composite International Diagnostic Interview (UM-CIDI) was administered by trained lay interviewers to generate lifetime DSM-III-R diagnoses. Unlike previous studies, the results of this study provided no evidence of a U-shaped or J-shaped curve or relationship between alcohol use and mental health. Lifetime abstainers had the lowest risks for all mental disorders examined, while former at-risk drinkers (those who had not had a drink in the previous year but at one time regularly drank more than 12 drinks a week) had the highest risks, even after adjustment for age and gender.

Objective: To describe the extent of psychiatric disorder and mental health service utilization in a representative outpatient alcohol and other drug (AOD) treatment sample in New Zealand. Method: A total of 105 patients were randomly recruited from two outpatient AOD treatment services in New Zealand and completed a diagnostic interview within the first 2 months of treatment. Axis I psychiatric diagnoses were made using the computerized Composite International Diagnostic Interview (CIDI-Auto), and were supplemented by the South Oaks Gambling Scale (SOGS) and the conduct disorder and antisocial personality disorder section of the Diagnostic Interview for Genetic Studies (DIGS). Results: Seventy-four per cent of the sample had a current non-substance or gambling axis I disorder, with a lifetime rate of 90%. The most commonly diagnosed of these coexisting psychiatric disorders were major depressive episode (34%), social phobia (31%) and posttraumatic stress disorder (31%). Past contact with mental health services was common, while contact at the time of baseline assessment was uncommon. Conclusions: Coexisting psychiatric disorder was the rule and not the exception in this sample. AOD patients are clearly part of the larger population of mental health patients. AOD services need to be capable of comprehensive assessment and treatment planning, which includes coexisting psychiatric disorders, and should work toward better integration with other mental health services.

BackgroundNo national data on lifetime prevalence and risk factors for DSM–IV psychiatric disorders are available in Mexico.AimsTo present data on lifetime prevalence and projected lifetime risk, age at onset and demographic correlates of DSM–IV psychiatric disorders assessed in the Mexican National Comorbidity Survey.MethodThe survey was based on a multistage area probability sample of non-institutionalised people aged 18–65 years in urban Mexico. The World Mental Health Survey version of the Composite International Diagnostic Interview was administered by lay interviewers.ResultsOf those surveyed, 26.1% had experienced at least one psychiatric disorder in their life and 36.4% of Mexicans will eventually experience one of these disorders. Half of the population who present with a psychiatric disorder do so by the age of 21 and younger cohorts are at greater risk for most disorders.ConclusionsOur results suggest an urgent need to re-evaluate the resources allocated for the detection and treatment of psychiatric illnesses in Mexico.

BackgroundFew South American studies have examined current prevalence rates of psychiatric disorders.AimsTo examine prevalence rates in a nationally representative adult population from Chile.MethodThe Composite International Diagnostic Interview was administered to a stratified random sample of 2978 individuals from four provinces representative of the country's population. Six-month and 1-month prevalence rates were estimated. Demographic correlates, comorbidity and service use were examined.ResultsNearly a fifth of the Chilean population had had a psychiatric disorder during the preceding 6 months. The 6-month and 1-month prevalence rates were 19.7% and 16.7% respectively. For the 6-month prevalence the five most common disorders were simple phobia, social phobia, agoraphobia, major depressive disorder and alcohol dependence. Less than 30% of those with any psychiatric diagnosis had a comorbid psychiatric disorder and the majority of them had sought treatment from mental health services.ConclusionsCurrent prevalence studies are useful indicators of service needs. People with comorbid psychiatric conditions have high rates of service use. The low rate of comorbidity in Chile merits further study.

Background.Population-based studies have identified that delusional-like experiences (DLEs) are common in the general population. While there is a large literature exploring the relationship between poor social support and risk of mental illness, there is a lack of empirical data examining the association of poor social support and DLEs. The aim of the study was to explore the association between social support and DLEs using a large, nationally representative community sample.Methods.Subjects were drawn from a national multistage probability survey of 8841 adults aged between 16 and 85 years. The Composite International Diagnostic Interview was used to identify DLEs, common psychiatric disorders and physical disorders. Eight questions assessed various aspects of social support with spouse/partners and other family and friends. We examined the relationship between DLEs and social support using logistic regression, adjusting for potential confounding factors.Results.Of the sample, 8.4% (n = 776) positively endorsed one or more DLEs. Individuals who (a) had the least contact with friends, or (b) could not rely on or confide in spouse/partner, family or friends were significantly more likely to endorse DLEs. The associations remained significant after adjusting for a range of potential confounding factors.Conclusions.DLEs are associated with impoverished social support in the general population. While we cannot exclude the possibility that the presence of isolated DLEs results in a reduction of social support, we speculate that poor social support may contribute in a causal fashion to the risk of DLEs.

This chapter recounts Julius Chambers's achievements during college, graduate school, and law school. After graduating summa cum laude from North Carolina College for Negroes and obtaining his masters degree in history at the University of Michigan, Chambers was admitted to the University of North Carolina School of Law, desegregated the prior decade by federal court order over the forceful objections of University and North Carolina officials. Chambers, despite being ranked 112th among the 114 students admitted to the Class of 1962 and notwithstanding a generally unwelcoming, often hostile atmosphere at the Law School and on campus, became editor-in-chief of the Law Review and graduated first in his class. This chapter also details Chambers's marriage to Vivian Giles and the couple's decision to move to New York City when, after no North Carolina law firm would grant Chambers a job interview, Columbia Law School quickly stepped forward with the offer of a one-year fellowship.

SummaryRecent studies have suggested that psychosocial factors play an important part in the prediction of the course of minor psychiatric disorders. Fifty-nine new psychiatric out-patients suffering from minor disorders were assessed, using standardized clinical and social interviews, and 52 were followed up after one year and the clinical assessment repeated. Social and clinical factors were equally important predictors of the number of months ill in the survey year, but social and constitutional variables were superior in the prediction of percentage change in symptoms over the year.The results of correlation, factor and multiple regression analyses suggest that the course of minor psychiatric disorder is best predicted by three sets of variables which are, in order of importance, the patient's material social circumstances, his clinical symptoms and his ‘genetic risk’ scores.

BackgroundSuicide is the 11th leading cause of death in the USA. Suicide rates vary across ethnic groups. Whether suicide behavior differs by ethnic groups in the USA in the same way as observed for suicide death is a matter of current discussion. The aim of this report was to compare the lifetime prevalence of suicide ideation and attempt among four main ethnic groups (Asians, Blacks, Hispanics, and Whites) in the USA.MethodSuicide ideation and attempts were assessed using the World Mental Health version of the Composite International Diagnostic Interview (WMH-CIDI). Discrete time survival analysis was used to examine risk for lifetime suicidality by ethnicity and immigration among 15 180 participants in the Collaborative Psychiatric Epidemiological Surveys (CPES), a group of cross-sectional surveys.ResultsSuicide ideation was most common among Non-Hispanic Whites (16.10%), least common among Asians (9.02%) and intermediate among Hispanics (11.35%) and Non-Hispanic Blacks (11.82%). Suicide attempts were equally common among Non-Hispanic Whites (4.69%), Hispanics (5.11%) and Non-Hispanic Blacks (4.15%) and less common among Asians (2.55%). These differences in the crude prevalence rates of suicide ideation decreased but persisted after control for psychiatric disorders, but disappeared for suicide attempt. Within ethnic groups, risk for suicidality was low among immigrants prior to migration compared to the US born, but equalized over time after migration.ConclusionsEthnic differences in suicidal behaviors are explained partly by differences in psychiatric disorders and low risk prior to arrival in the USA. These differences are likely to decrease as the US-born proportion of Hispanics and Asians increases.

The context for the present study is the one-year initial teacher education course for postgraduates specialising in physical education at the secondary level. The research focus is on the conflicts which pre service teachers experience during the school practice element of a University- School Partnership Scheme based on the new government criteria and procedures introduced in the DFE Circular No. 9/92 for England and Wales. Fifty-three postgraduate students completed report forms about their teaching concerns at the end of each week of a six-week and an eleven-week block practice, and, of the 1510 concerns reported, 257 (17.02%) were classed as conflicts. A content analysis of the 'conflict' concerns revealed four general categories of conflict, and these were related to school staff and peers, the school and university working procedures, the demands from the school and the university, and beliefs and values about the teaching profession. The paper argues that such conflicts are viewed with much apprehension by pre-service teachers because of the additional responsibilities and powers placed on school subject mentors and the more limited time available in the university to prepare for the practical activities. Therefore, it is suggested that University-School Partnership Schemes should build in arrangements that give pre service teachers the opportunity to resolve deep-seated problems by being able to approach neutral staff from either the university or the school.
