Perceived helpfulness of treatment for social anxiety disorder: findings from the WHO World Mental Health Surveys.

Purpose: To investigate the prevalence and predictors of perceived helpfulness of treatment in persons with a history of DSM-IV social anxiety disorder (SAD), using a worldwide population-based sample.

Methods: The World Health Organization World Mental Health Surveys is a coordinated series of community epidemiological surveys of non-institutionalized adults; 27 surveys in 24 countries (16 in high-income; 11 in low/middle-income countries; N = 117,856) included people with a lifetime history of treated SAD.

Results: In respondents with lifetime SAD, approximately one in five ever obtained treatment.

Perceived helpfulness of bipolar disorder treatment: Findings from the World Health Organization World Mental Health Surveys.

Objectives: To examine patterns and predictors of perceived treatment helpfulness for mania/hypomania and associated depression in the WHO World Mental Health Surveys.

Methods: Face-to-face interviews with community samples across 15 countries found n = 2,178 who received lifetime mania/hypomania treatment and n = 624 with lifetime mania/hypomania who received lifetime major depression treatment. These respondents were asked whether treatment was ever helpful and, if so, the number of professionals seen before receiving helpful treatment.

Mental health of the old- and new-generation migrant workers in China: who are at greater risk for psychological distress?

Rural-to-urban migrant workers (MWs) are a large vulnerable population in China and, recently, the new-generation MWs (those born in 1980 or later) have become the majority of this population. Examining difference in the epidemiology of poor mental health between the new- and old-generation (those born before 1980) MWs would facilitate mental health promotion efforts. However, very few related studies are available and they produced conflicting findings.

Prevalence and correlates of major depressive disorder among rural-to-urban migrant workers in Shenzhen, China.

Background: In China, rural-to-urban migrant workers (MWs) are a large and vulnerable population that may be at high risk for depression, but previous studies focused on depressive symptoms of MWs and no study has investigated the epidemiology of major depressive disorder (MDD). The objective of this study was to determine the prevalence and correlates of one-month and lifetime MDD among MWs in Shenzhen, China, and mental health services utilization of MWs with lifetime MDD.

Methods: A total of 3031 MWs were recruited from 10 manufacturing factories and interviewed with the Chinese version of the Mini International Neuropsychiatric Interview.

Prevalence of psychological symptoms in contemporary Chinese rural-to-urban migrant workers: an exploratory meta-analysis of observational studies using the SCL-90-R.

Purpose: (1) To estimate the pooled prevalence of psychological symptoms in Chinese migrant workers (CMWs), as measured using the Symptom Checklist-90-R (SCL-90-R) in observational studies conducted in China, and (2) to explore the potential variables associated with the SCL-90-R Global Severity Index (GSI), the overall mental health indicator of CMWs.

Methods: We performed a comprehensive literature search of the major English and Chinese databases (to June 2012). Cross-sectional surveys and case-control studies of CMWs (and controls where appropriate) that reported at least one subscale score of the SCL-90-R were included.

Development of lifetime comorbidity in the World Health Organization world mental health surveys.

Context: Although numerous studies have examined the role of latent variables in the structure of comorbidity among mental disorders, none has examined their role in the development of comorbidity.

Objective: To study the role of latent variables in the development of comorbidity among 18 lifetime DSM-IV disorders in the World Health Organization World Mental Health Surveys.

Design: Nationally or regionally representative community surveys.

Childhood adversities and adult psychopathology in the WHO World Mental Health Surveys.

Background: Although significant associations of childhood adversities with adult mental disorders are widely documented, most studies focus on single childhood adversities predicting single disorders.

Aims: To examine joint associations of 12 childhood adversities with first onset of 20 DSM-IV disorders in World Mental Health (WMH) Surveys in 21 countries.

Method: Nationally or regionally representative surveys of 51 945 adults assessed childhood adversities and lifetime DSM-IV disorders with the WHO Composite International Diagnostic Interview (CIDI).

Screening for serious mental illness in the general population with the K6 screening scale: results from the WHO World Mental Health (WMH) survey initiative.

Data are reported on the background and performance of the K6 screening scale for serious mental illness (SMI) in the World Health Organization (WHO) World Mental Health (WMH) surveys. The K6 is a six-item scale developed to provide a brief valid screen for Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV) SMI based on the criteria in the US ADAMHA Reorganization Act. Although methodological studies have documented good K6 validity in a number of countries, optimal scoring rules have never been proposed.

[Survey on mental disorders among registered residents and non-registered residents in Shenzhen].

Objective: To study the prevalence and distribution of mental disorders among registered and non-registered residents in Shenzhen.

Methods: An epidemiological survey on mental disorders were carried out in Shenzhen by stratified multi-stage randomized sampling method; 7134 respondents were assessed through face-to-face interview, using the WHO standardized version on World Mental Health (WMH) Survey Initiative of the Composite International Diagnostic Interview (CIDI3.1).
