Methods: The World Health Organization World Mental Health Surveys, 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 1 in 5 ever obtained treatment. Among these (n=1,322), cumulative probability of receiving treatment they regarded as helpful after seeing up to 7 professionals was 92.2%. However, only 30.2% persisted this long, resulting in 65.1% ever receiving treatment perceived as helpful. Perceiving treatment as helpful was more common in female respondents, those currently married, more highly educated, and treated in non-formal healthcare settings. Persistence in seeking treatment for SAD was higher among those with shorter delays in seeking treatment, in those receiving medication from a mental health specialist, and those with more than 2 lifetime anxiety disorders. Conclusions: The vast majority of individuals with SAD do not receive any treatment. Among those who do, the probability that people treated for SAD obtain treatment they consider helpful increases considerably if they persisted in help-seeking after earlier unhelpful treatments.

We aimed to identify groups of participants with differing vulnerabilities by examining the course of internalizing psychopathology up to age 45.MethodsWe used data from 24158 participants (aged 45+) in 23 population-based cross-sectional World Mental Health Surveys. Internalizing disorders were assessed with the Composite International Diagnostic Interview (CIDI). We applied latent class growth analysis (LCGA) and investigated the characteristics of identified classes using logistic or linear regression.ResultsThe best-fitting LCGA solution identified eight classes: a healthy class (81.9%), three childhood-onset classes with mild (3.7%), moderate (2.0%), or severe (1.1%) internalizing comorbidity, two puberty-onset classes with mild (4.0%) or moderate (1.4%) comorbidity, and two adult-onset classes with mild comorbidity (2.7% and 3.2%).

While online and offline gaming may produce undesired negative effects on players, we know little about the nosology of IGD and its prevalence, especially in countries with emerging economies. Methods A self-administered survey has been employed to estimate prevalence of DSM-5 IGD and study the structure and performance of an instrument in Spanish to measure DSM-5 IGD among 7,022 first-year students in 5 Mexican universities that participated in the University Project for Healthy Students (PUERTAS), part of the World Health Organization’s World Mental Health International College Student Initiative. Results The scale for IGD showed unidimensionality with factor loadings between 0.694 and 0.838 and a Cronbach’s α = .816. Items derived from gaming and from substance disorders symptoms mixed together. We found a 12-month prevalence of IGD of 5.2% in the total sample; prevalence was diffe...

Methods Data come from data collected from 6710 adults with 12 month mental disorder surveys across seven surveys in six countries in North (USA), Central (Mexico) and South (Argentina, Brazil, Colombia, Peru) America who were interviewed 2001–2015 as part of the World Health Organization (WHO) World Mental Health (WMH) Surveys. DSM-IV diagnoses were made with the WHO Composite International Diagnostic Interview (CIDI). Interviews also assessed service utilization by the treatment sector, adequacy of treatment received and socio-demographic correlates of treatment. Results Little over one in four of respondents with any 12 month DSM-IV/CIDI disorder received any treatment. Although the v...

Aunado a que cada vez más la cantidad y frecuencia de consumo de sustancias psicoactivas ha aumentado fundamentalmente en la población joven, tanto en aquéllos que trabajan, como en los que estudian, o realizan ambas o ninguna de las dos actividades, considerando un factor de riesgo no asistir a la escuela y el desempleo. El objetivo del presente trabajo es conocer los discursos de jóvenes que no estudian ni trabajan sobre su consumo de drogas. Se tomaron como base los relatos de 10 jóvenes que representan esta situación. Los métodos utilizados para la recolección y análisis de los datos son de corte cualitativo a través de entrevistas focalizadas. Los resultados forman parte de la investigación de tesis doctoral “La construcción social de la identidad en jóvenes que no estudian ni trabajan”, centrándose en los discursos de los jóvenes entrevistados que consumen drogas como una forma ...

In particular, the proportion of migrant, unemployed, and poorly educated residents in neighborhoods of these urban areas may characterize group contexts and shape residents' health. Cross-sectional household interviews of 7251 adults were completed across 83 neighborhoods of Buenos Aires, Argentina; Medellín, Colombia; São Paulo, Brazil; Lima, Peru; and Mexico City, Mexico as part of the World Mental Health Survey Initiative. Past-year internalizing and externalizing mental disorders were assessed, and multilevel models were used. Living in neighborhoods with either an above-average or below-average proportion of migrants and highly educated residents was associated with lower odds of any internalizing disorder (for proportion migrants: OR 0.75, 95% CI 0.62-0.91 for the bottom tertile and OR 0.79, 95% CI 0.67-0.94 for the top tertile compared...

The policy implications of these results for the necessary expansion of mental health services in Argentina are sufficiently great that more direct estimates of the population burdens of common mental disorders are needed. Therefore, the purpose is to present the first results regarding lifetime prevalence, projected lifetime risk up to age 75, age-of-onset, cohort effects and socio-demographic correlates of DSM-IV mental disorders among adults (18+) from the general population of urban areas of Argentina. A multistage clustered area probability household survey was administered to 3927 individuals using the World Mental Health Composite International Diagnostic Interview. Lifetime prevalence of any disorder was 29.1% and projected lifetime ...

Data were analyzed from 26 population surveys in the World Health Organization World Mental Health Surveys. A total of 71 083 respondents ages 18+ participated. The Composite International Diagnostic Interview assessed exposure to traumatic events as well as 30-day, 12-month, and lifetime PTSD. Respondents were also assessed for treatment in the 12 months preceding the survey. Age of onset distributions were examined by country income level. Associations of PTSD were examined with country income, world region, and respondent demographics. The cross-national lifetime prevalence of PTSD was 3.9% in the total sample and 5.6% among the trauma exposed. Half of respondents with PTSD reported persistent symptoms. Treatment seeking in high-income countries (53.5%) was rough...

Non-suicidal self-injuries (NSSI) are a worldwide health problem that affects principally young people, and can impact negatively the mental and physical health of those that self-injure. Objective. To examine the frequency of NSSI in 564 undergraduate students (132 male, 432 female) from Mexico City and the association of NSSI with depressive symptoms, anxiety, impulsivity, self-efficacy, and emotion regulation. Method. A convenience sample of 564 undergraduate students (aged 17-26 years) from eight universities in the Mexico City metropolitan area completed a survey in their classrooms. Results. Of the total sample, 30.9% had experimented at some point in their lifetime with NSSI on one to four occasions, while 26.9% had recurrent NSSI (i.e., five or more occasions). Nearly eleven percent self-injured in the prior 12 months. The NSSI most often reported among those who self-injured was cutting oneself (48.0%). Recurrent self-injurers reported higher levels of depress...

Objetivo: Entender, desde la perspectiva de los adolescentes, los aspectos de la enfermedad que afectan sus relaciones con padres y pares y su imagen corporal. Método: Este estudio, de tipo exploratorio, descriptivo y cualitativo, se realizó mediante entrevistas a profundidad. Participaron adolescentes de entre 12 y 20 años de edad con IRC, pacientes de un hospital de segundo nivel del estado de Aguascalientes (México). Con el software Atlas Ti, se elaboraron matrices para la codificación de categorías y subcategorías. Resultados: En cuanto a su imagen corporal, los adolescentes manifestaron tener preocupaciones por cuestiones propias de la enfermedad, como inflamación, pérdida de peso y cambio en la c...
