CONTEXT Little is known about the extent or severity of untreated mental disorders, especially in less-developed countries. [] Key MethodDESIGN, SETTING, AND PARTICIPANTS Face-to-face household surveys of 60 463 community adults conducted from 2001-2003 in 14 countries in the Americas, Europe, the Middle East, Africa, and Asia.

Tables from this paper

Twelve‐month prevalence, severity, and treatment of common mental disorders in communities in Japan: preliminary finding from the World Mental Health Japan Survey 2002–2003

The study confirmed that the prevalence of DSM‐IV mental disorders was equal to that observed in Asian countries but higher than that in Western countries and low even for those who suffered severe or moderate disorders.

Lifetime and 12-month prevalence, severity and unmet need for treatment of common mental disorders in Japan: results from the final dataset of World Mental Health Japan Survey

The results suggest lower prevalence of mental disorders in Japan than that in Western countries, although the general pattern of disorders, risk factors and unmet need for treatment were similar to those in other countries.

Lifetime prevalence and age-of-onset distributions of mental disorders in the World Health Organization's World Mental Health Survey Initiative.

As many mental disorders begin in childhood or adolescents, interventions aimed at early detection and treatment might help reduce the persistence or severity of primary disorders and prevent the subsequent onset of secondary disorders.

The prevalence and correlates of DSM-IV disorders in the Iraq Mental Health Survey (IMHS).

Data on the prevalence and correlates of anxiety, mood, behavioral, and substance disorders are presented from a 2007-8 national survey of the Iraq population, the Iraq Mental Health Survey (IMHS).

Proportion of patients without mental disorders being treated in mental health services worldwide.

Dose-response associations were found between number of indicators of need and treatment and the vast majority of treatment in the WMH countries goes to patients with mental disorders or other problems expected to benefit from treatment.

Prevalence, severity, and comorbidity of 12-month DSM-IV disorders in the National Comorbidity Survey Replication.

Although mental disorders are widespread, serious cases are concentrated among a relatively small proportion of cases with high comorbidity, as shown in the recently completed US National Comorbidities Survey Replication.

Twelve-month prevalence and treatment gap for common mental disorders: Findings from a large-scale epidemiological survey in India

The survey revealed a huge treatment gap of 95%, with only 5 out of 100 individuals with common mental disorders receiving any treatment over the past year, and these estimates are likely to be conservative due to under-reporting or inadequate detection due to cultural factors.



Cross-national comparisons of the prevalences and correlates of mental disorders. WHO International Consortium in Psychiatric Epidemiology.

It is shown that mental disorders were often chronic, although chronicity was consistently higher for anxiety disorders than for mood or substance-use disorders, and there is a need for demonstration projects of early outreach and intervention programmes for people with early-onset mental disorders, as well as quality assurance programmes to look into the widespread problem of inadequate treatment.

Prevalence of ICD-10 mental disorders in a catchment area in the city of São Paulo, Brazil

The presence of psychiatric diagnosis increased the use of services, with a low proportion of subjects seeking specialty mental care, similar to findings in other countries.

Lifetime and 12-month prevalence of DSM-III-R psychiatric disorders in the United States. Results from the National Comorbidity Survey.

The prevalence of psychiatric disorders is greater than previously thought to be the case, and morbidity is more highly concentrated than previously recognized in roughly one sixth of the population who have a history of three or more comorbid disorders.

Common mental disorders and disability across cultures. Results from the WHO Collaborative Study on Psychological Problems in General Health Care.

The consistent relationship of psychopathology and disability indicates the compelling personal and socioeconomic impact of common mental illnesses across cultures and suggests the importance of impairments of higher-order human capacities as determinants of functional disability.

The World Mental Health (WMH) Survey Initiative version of the World Health Organization (WHO) Composite International Diagnostic Interview (CIDI)

An overview of the World Mental Health Survey Initiative version of the WHO Composite International Diagnostic Interview (CIDI) is presented and a discussion of the methodological research on which the development of the instrument was based is discussed.

Revised prevalence estimates of mental disorders in the United States: using a clinical significance criterion to reconcile 2 surveys' estimates.

Establishing the clinical significance of disorders in the community is crucial for estimating treatment need and characterizing the utility of clinically significant symptoms in determining treatment need even when some criteria of the disorder are not met.

The Netherlands Mental Health Survey and Incidence Study (NEMESIS): objectives and design

The objectives and design of a prospective study of the prevalence, incidence and course of psychiatric disorders in a representative sample of non-institutionalized Dutch adults, which determines the lifetime occurrence of DSM-III-R disorders are described.

Limitations of diagnostic criteria and assessment instruments for mental disorders. Implications for research and policy.

The health policy implications of discrepant and/or high prevalence rates for determining treatment need in the context of managed care definitions of "medical necessity" are discussed.

Mild disorders should not be eliminated from the DSM-V.

It is demonstrated that the DSM-III-R disorders in the baseline National Comorbidity Survey (NCS) can be placed on a severity gradient that has a dose-response relationship with outcomes assessed a decade later in the NCS follow-up survey (NCS-2) and that no inflection point exists at the mild severity level.

Income differences in persons seeking outpatient treatment for mental disorders: a comparison of the United States with Ontario and The Netherlands.

There were significant differences among countries in the association between income and sector of mental health care treatment, and differential access to the specialty sector for low-income people in the United States is associated with worse mental health outcomes.
