Prevalence of child and adolescent mental disorders in Chile: a community epidemiological study.

Background:  In Latin America, there is limited research on the prevalence of mental disorders in children and adolescents. This Chilean survey is the first national representative survey in the Latin American region to examine the prevalence of diagnostic and statistical manual-IV (DSM-IV) psychiatric disorders in the region in children and adolescents.

Methods:  Subjects aged 4-18 were selected using a stratified multistage design.

Prevalence of child and adolescent psychiatric disorders in Santiago, Chile: a community epidemiological study.

Purpose: To determine the prevalence of DSM-IV psychiatric disorders in a representative sample of children and adolescents living in Santiago, Chile, as part of a national sample.

Method: Subjects aged 4-18 were selected using a stratified multistage design. First, ten municipalities/comunas of Santiago were selected; then the blocks, homes, and child or adolescent to be interviewed were chosen.

[Prevalence of mental health disorders among children and adolescents living in southern Chile].

Aim: To determine the prevalence of DSM-IV psychiatric disorders in a representative sample of children and adolescents living in the province of Cautin, Chile.

Material And Methods: Subjects aged between 4 and 18 years were selected in an aleatory stratified multistage fashion.

SUMMARYIn the last decade, our understanding of posttraumatic stress disorder (PTSD) has progressed from studies of war veterans and specific disaster victims to studies that examine the epidemiology of PTSD in the United States (USA) population. Epidemiologic data on PTSD in developing countries is an understudied area with the majority of studies were developed in the USA and other developed countries. Of the few epidemiological surveys undertaken in other countries, most of them have focused its interest on the prevalence rates of PTSD and its risk factors for following specific traumatic events.

Psychiatric epidemiology of the elderly population in Chile.

Objectives: Little attention has been given to the prevalence rate of mental illness among elderly adults in Latin America. The prevalence rates for psychiatric disorders in Chile among those 65 and older compared with younger individuals, and the prevalence rate of psychiatric disorders among those age 75 and older are presented.

Design: A stratified random sample of 2,659 individuals.

Childhood trauma, trauma in adulthood, and psychiatric diagnoses: results from a community sample.

This study compared the prevalence rates of various psychiatric disorders in persons with first onset of a potentially traumatic event (PTE) in childhood, persons with first onset of a PTE in adulthood, and those with no history of a PTE in a representative sample of Chileans. The Diagnostic of Statistical Manual of Mental Disorders, Revised Third Edition (DSM-III-R), posttraumatic stress disorder, and antisocial personality disorder modules from the Diagnostic Interview Schedule and modules for a range of DSM-III-R diagnoses from the Composite International Diagnostic Interview were administered to 2390 Chileans. The study found that exposure to a lifetime PTE was associated with a higher probability of psychiatric morbidity than no PTE exposure.

Regional differences in psychiatric disorders in Chile.

Background: Psychiatric epidemiological surveys in developing countries are rare and are frequently conducted in regions that are not necessarily representative of the entire country. In addition, in large countries with dispersed populations national rates may have low value for estimating the need for mental health services and programs.

Methods: The Chile Psychiatric Prevalence Study using the Composite International Diagnostic Interview was conducted in four distinct regions of the country on a stratified random sample of 2,978 people.

Lifetime and 12-month prevalence of DSM-III-R disorders in the Chile psychiatric prevalence study.

Objective: Although several epidemiological studies of the prevalence of psychiatric disorders have been conducted in Latin America, few of them were national studies that could be used to develop region-wide estimates. Data are presented on the prevalence of DSM-III-R disorders, demographic correlates, comorbidity, and service utilization in a nationally representative adult sample from Chile.

Method: The Composite International Diagnostic Interview was administered to a stratified random sample of 2,978 individuals from four provinces representative of the country's population age 15 and older.

Epidemiology of trauma, post-traumatic stress disorder (PTSD) and co-morbid disorders in Chile.

Background: In this study we examined the prevalence rates of post-traumatic stress disorder (PTSD), types of trauma most often associated with PTSD, the co-morbidity of PTSD with other lifetime psychiatric disorders, which disorders preceded PTSD, and gender differences in PTSD and trauma exposure in a representative sample of Chileans.

Method: The DSM-III-R PTSD and antisocial personality disorder modules from the Diagnostic Interview Schedule (DIS) and modules for a range of DSM-III-R diagnoses from the Composite International Diagnostic Interview (CIDI) were administered to a representative sample of 2390 persons aged 15 to over 64 years in three cities in Chile.

Results: The lifetime prevalence of PTSD was 4.

Prediction of depression in European general practice attendees: the PREDICT study.

Background: Prevention of depression must address multiple risk factors. Estimating overall risk across a range of putative risk factors is fundamental to prevention of depression. However, we lack reliable and valid methods of risk estimation.

[Service use patterns among adults with mental health problems in Chile].

Objective: To describe the patterns in the use of general health services and specialized health services among adults with mental health problems in Chile, as well as those persons' level of satisfaction with the services. The overall objective was to optimize the use of the limited resources available for mental health care in the countries of the Americas, especially Chile.

Methods: The diagnoses and the patterns of use of mental health services were obtained from the Chilean Study of Psychiatric Prevalence (Estudio Chileno de Prevalencia Psiquiátrica).

Psychiatric disorders among the Mapuche in Chile.

Background: The Mapuche are the largest indigenous group in Chile; yet almost all data on the mental health of indigenous populations are from North America.

Aim: The study examines the differential DSM-III-R prevalence rates of psychiatric disorders and service utilization among indigenous and non-indigenous community residence.

Methods: The Composite International Diagnostic Interview (CIDI) was administered to a stratified random sample of 75 Mapuche and 434 non-Mapuche residents of the province of Cautín.

Population prevalence of psychiatric disorders in Chile: 6-month and 1-month rates.

Background: Few South American studies have examined current prevalence rates of psychiatric disorders.

Aims: To examine prevalence rates in a nationally representative adult population from Chile.

Method: The Composite International Diagnostic Interview was administered to a stratified random sample of 2978 individuals from four provinces representative of the country's population.

Use of mental health services in Chile.

Objective: S: To address the growing burden of mental illness in Latin America, a better understanding of mental health service use and barriers to care is needed. Although many Latin American countries have nationalized health care systems that could potentially improve access to care, significant barriers to care remain. The authors report the results of a study examining mental health service utilization in the general population of Chile.

[Chilean study on the prevalence of psychiatric disorders (DSM-III-R/CIDI) (ECPP)].

Background: The Diagnostic and Statistic Manual (DSM) solved the problem of diagnostic criteria for psychiatric diseases. Highly structured interviews such as Composite International Diagnostic Interview (CIDI) allow the evaluation of psychiatric disorders in large samples, with great accuracy.

Aim: To report the prevalence rates of psychiatric disorders in a representative sample of Chilean individuals.
