Patterns and predictors of the transition between minimally adequate treatment and effective treatment coverage for mental disorders
BACKGROUND: The quality of mental disorder treatment varies widely, with many patients not receiving treatments based on evidence-based guidelines. We examine data from the World Mental Health (WMH) surveys to investigate prevalence and correlates of receiving effective treatment coverage (ETC) among patients receiving minimally adequate treatment (MAT) in the 12 months before interview. METHODS: Data come from 25 WMH surveys carried out in 21 co…

Occupational violence toward mental health professionals during the Covid-19 pandemic
Approximately one in ten MHCP experienced OV during the COVID-19 pandemic. This figure is consistent with the range of OV against MHCPs reported prior to the pandemic and indicates that efforts are needed to prevent and manage OV and its negative emotional consequences among MHCP, particularly in aforementioned high-risk groups during health emergencies, and addressing both proximal and distal environmental factors related to OV toward MHCPs
Current Status of Mental Health in Mexico City
There is limited information on the prevalence of mental health symptoms among the population of Mexico City. To provide an update and determine the prevalence of symptoms associated with various disorders in the city, a modified version of the "Screener Questionnaire" was used, the same instrument employed in the National Survey on Drug, Alcohol, and Tobacco Use (ENCODAT) 2016-2017. Data were collected at PILARES centers in different boroughs of…
HIV-Related Stigma and Treatment Adherence Among Gay, Bisexual, and Other Men Who Have Sex with Men Who Use Crystal Meth in the Metropolitan Area of Mexico City
Internationally, HIV-related stigma and crystal methamphetamine (meth) use have been described as barriers to treatment adherence among gay, bisexual, and other men who have sex with men (gbMSM). Crystal meth use has been increasing among gbMSM in the Metropolitan Area of Mexico City (MAMC). Therefore, this study aimed to determine the association between HIV-related stigma and HIV treatment adherence among gbMSM who use crystal meth in the MAMC.…
Age of onset and cumulative risk of mental disorders
BACKGROUND: Information on the frequency and timing of mental disorder onsets across the lifespan is of fundamental importance for public health planning. Broad, cross-national estimates of this information from coordinated general population surveys were last updated in 2007. We aimed to provide updated and improved estimates of age-of-onset distributions, lifetime prevalence, and morbid risk. METHODS: In this cross-national analysis, we analyse…
Dating Violence among Undergraduate Medical Students at a Public University in Mexico City
Gender-based violence (GBV) and cyber-aggression are growing problems in Mexico, but there is a dearth of information on their associated risks. We aimed to determine the prevalence of dating violence (DV) and cyber-aggression in a public campus and compared students' acceptability of abusive DV based on their sex and sexual orientation. We employed a cross-sectional design to survey 964 first-year medical students attending a public university. …
Anxiety among Central American Migrants in Mexico
Migration exposes Central American migrants, particularly those who migrate without documents, to a range of incidents, dangers, and risks that increase their vulnerability to anxiety symptoms. In most cases, the poverty, conflict, and violence they experience in their countries of origin are compounded by the unpredictable conditions of their journey through Mexico. The objective of this study was to explore the association between the presence …
Changes in Attitudes toward People with Substance Use Disorder
These results suggest that it may not be recognized that PWSUD may have a health problem and that this helps to increase stigmatization towards this population
Lower-Risk Cannabis Use Guidelines (LRCUG) for reducing health harms from non-medical cannabis use
BACKGROUND: Cannabis use is common, especially among young people, and is associated with risks for various health harms. Some jurisdictions have recently moved to legalization/regulation pursuing public health goals. Evidence-based 'Lower Risk Cannabis Use Guidelines' (LRCUG) and recommendations were previously developed to reduce modifiable risk factors of cannabis-related adverse health outcomes; related evidence has evolved substantially sinc…

Covid ‐19 and alcohol in Mexico
The present text comments on Stockwell and colleagues' paper documenting the high burden of alcohol use in COVID‐19 related mortality in the USA and Canada in North America and the absence of a control policy in several countries of the world. This comment adds information about the third country in North America, Mexico. It describes alcohol use during the COVID lockdown and its consequences, highlighting the control efforts through public healt…
Diagnostic classification of irritability and oppositionality in youth
BACKGROUND: Severe irritability has become an important topic in child and adolescent mental health. Based on the available evidence and on public health considerations, WHO classified chronic irritability within oppositional defiant disorder (ODD) in ICD-11, a solution markedly different from DSM-5's (i.e. the new childhood mood diagnosis, disruptive mood dysregulation disorder [DMDD]) and from ICD-10's (i.e. ODD as one of several conduct disord…
Cannabis Use in People With Obsessive-Compulsive Symptomatology
Recent studies suggest that the endocannabinoid system could play an important role in the physiopathology of obsessive-compulsive disorder (OCD). There are reports of effective treatment with derivatives of tetrahydrocannabinol (THC). The study of the genetic factor associated with psychiatric disorders has made possible an exploration of its contribution to the pharmacological response. However, very little is known about the genetic factor or …
Mental Health Problems among Covid-19 Frontline Healthcare Workers and the Other Country-Level Epidemics
COVID-19 frontline healthcare workers (FHCW) are struggling to cope with challenges that threaten their wellbeing. We examine the frequency and predictors of the most frequent mental health problems (MHP) among FHCW during the first COVID-19 peak in Mexico, one of the most severely affected countries in terms of FHCW's COVID-19 mortality. A cross-sectional survey was conducted between May 8 and August 18, 2020. A total of 47.5% of the sample ( n …
Testing the Synergistic Effects of Depression, Anxiety, and Substance Use in Unsafe Sex
Somebody Is Gonna Be Hurt
Involuntary drug treatment (IDT) is ineffective in decreasing drug use, yet it is a common practice. In Mexico, there are not enough professional residential drug treatment programs, and both voluntary and involuntary drug treatment is often provided by non-evidence based, non-professional programs. We studied the experiences of people who inject drugs (PWID) in Tijuana who were taken involuntarily to drug centers under the auspices of a federall…
Psychopathic Disorder Subtypes Based on Temperament and Character Differences
The concept of psychopathy has shifted from people who commit crimes to those with a particular personality and deviant behaviors. Although antisocial personality disorder is associated with psychopathy, it also seems common in individuals with narcissistic personality traits. Psychopathy may be the expression of earlier, persistent patterns of individual characteristics as personality. The psychobiological model of personality can be useful for …

Where Is the Opioid Use Epidemic in Mexico? A Cautionary Tale for Policymakers South of the US–Mexico Border
In North America, opioid use and its harms have increased in the United States and Canada over the past 2 decades. However, Mexico has yet to document patterns suggesting a higher level of opioid use or attendant harms. Historically, Mexico has been a country with low-level use of opioids, although heroin use has been documented. Low-level opioid use is likely attributable to structural, cultural, and individual factors. However, a range of dynam…
Supply control for illegal markets
Supply control approaches to drug problems focus on the production, distribution, and sale of illicit psychoactive substances, and include alternative development programmes in producer nations, control of precursor chemicals used to produce certain drugs (e.g. methamphetamines) interdiction at national borders, and the incarceration of drug dealers at all levels. There is no evidence that promoting alternative development as part of global drug …
Criminalization and decriminalization of drug possession
Research suggests that punishing drug users has some limitations as a major component of drug policy. An increasing number of countries and sub-national jurisdictions have therefore been reducing or eliminating criminal penalties for possession of small amounts of drugs for personal use, on grounds both of proportionality and effectiveness-oriented policy. Most decriminalization or depenalization programmes involve the substitution of civil penal…
Illegal markets
Illegal drugs are commodities that are bought and sold in markets. Many farmers are engaged in small amounts of drug growing in the producing countries, but there are comparatively small numbers of refiners, smugglers, and top-level importers. Compared to most legal markets, there are many sellers relative to the number of buyers in drug markets. One consequence of the network character of drug distribution is its resilience. Eliminating individu…
The Effect of Migration to the United States on Substance Use Disorders Among Returned Mexican Migrants and Families of Migrants
Objectives. We examined the association between substance use disorders and migration to the United States in a nationally representative sample of the Mexican population. Methods. We used the World Mental Health version of the Composite International Diagnostic Interview to conduct structured, computer-assisted, face-to-face interviews with a cross-sectional sample of household residents aged 18 to 65 years who lived in Mexico in cities with a p…

Delay of First Treatment of Mental and Substance Use Disorders in Mexico
Objectives. We studied failure and delay in making initial treatment contact after the first onset of a mental or substance use disorder in Mexico as a first step to understanding barriers to providing effective treatment in Mexico. Methods. Data were from the Mexican National Comorbidity Survey (2001–2002), a representative, face-to-face household survey of urban residents aged 18 to 65 years. The age of onset for disorders was compared with the…
Substance Use and Cumulative Exposure to American Society
Objectives. We investigated whether Mexican immigration to the United States exerts transnational effects on substance use in Mexico and the United States. Methods. We performed a cross-sectional survey of 2336 Mexican Americans and 2460 Mexicans in 3 Texas border metropolitan areas and their sister cities in Mexico (the US–Mexico Study on Alcohol and Related Conditions, 2011–2013). We collected prevalence and risk factors for alcohol and drug us…
A Cross-National Study on Prevalence of Mental Disorders, Service Use, and Adequacy of Treatment Among Mexican and Mexican American Populations
Objectives. We examined differences in the use of mental health services, conditional on the presence of psychiatric disorders, across groups of Mexico’s population with different US migration exposure and in successive generations of Mexican Americans in the United States. Methods. We merged surveys conducted in Mexico (Mexican National Comorbidity Survey, 2001–2002) and the United States (Collaborative Psychiatric Epidemiology Surveys, 2001–200…
Immigration and Suicidal Behavior Among Mexicans and Mexican Americans
Objectives. We examined migration to the United States as a risk factor for suicidal behavior among people of Mexican origin. Methods. We pooled data from 2 nationally representative surveys in the United States (2001–2003; n = 1284) and Mexico (2001–2002; n = 5782). We used discrete time survival models to account for time-varying and time-invariant characteristics, including psychiatric disorders. Results. Risk for suicidal ideation was higher …
Alcohol Use Disorders in National Samples of Mexicans and Mexican-Americans
The authors show associations between immigration and alcohol disorders using data from the 1995 and 2000 U.S. National Alcohol Surveys and the 1998 Mexico National Household Survey on Addictions. The prevalence of alcohol dependence was 4.8% for the Mexicans, 4.2% for the Mexico-born immigrants, and 6.6% for the U.S.-born Mexican Americans. They found a general lack of significance for the immigration variables with few consistent dose-response …
Adolescent drug use in Mexico and among Mexican American adolescents in the United States
The authors compared high school students in Baja California Norte (BCN), Mexico (n = 775), with Mexican American students in Los Angeles (LA), California (n = 516). The students' use of cigarettes, alcohol, marijuana, cocaine, inhalants, and other illicit drugs were compared, because these vary by gender, country, and their age of first drug use and are influenced by demographic variables, individual characteristics, and environmental influences…
How Mental Health Interviews Conducted Alone, in the Presence of an Adult, a Child or Both Affects Adolescents’ Reporting of Psychological Symptoms and Risky Behaviors
A Transnational Study of Migration and Smoking Behavior in the Mexican-Origin Population
Objectives. We examined migration-related changes in smoking behavior in the transnational Mexican-origin population. Methods. We combined epidemiological surveys from Mexico (Mexican National Comorbidity Survey) and the United States (Collaborative Psychiatric Epidemiology Surveys). We compared 4 groups with increasing US contact with respect to smoking initiation, persistence, and daily cigarette consumption: Mexicans with no migrant in their f…

Alcohol consumption and pregnancy in the Mexican national addiction survey
In 1988, the General Directorate of Epidemiology and the Mexican Institute of Psychiatry conducted the first National Addiction Survey (ENA), providing regional and national data on alcohol, tobacco, and drug use. The ENA providing a subsample of women who have been pregnant at some time in their lives. There were 5,234 affirmative responses. Women were asked if they had suffered any of three adverse outcomes during their last pregnancy: spontane…
Screening for Alcohol Problems
Relatively little is known about the performance of screening instruments for alcohol use disorders in the general population compared to clinical populations, or among Mexicans or Mexican Americans. The sensitivity and specificity of three screening measures: CAGE, TWEAK, and holding five or more drinks (HOLD), for alcohol dependence, are compared between ER and general population samples in the U.S. (Santa Clara, County, California) and in Mexi…
Adolescent drug use in Mexico and among Mexican American adolescents in the United States

Psychometric Properties and Construct Validity of a Spanish Language Scale for Screening Antisocial Personality
The psychometric properties and construct validity of a Spanish self-report scale for screening antisocial personality (ASP) are evaluated. Evidence for validity was sought by comparing a household and an emergency room (ER) sample. Nine hundred and twenty men and women were part of a multistage, stratified, probability sample drawn from all 18–65 year olds in a city in Mexico. ER participants were 1511 patients 18–65 years of age sampled from th…
Prevalence and correlates of drug use disorders in Mexico
A noticeable number of Mexicans have a drug use disorder, but demand for treatment is limited, in part due to stigma. Our results indicate that there is an urgent need to organize the specialized services for persons with a substance abuse disorder according to the prevalence of dependence on different substances and the variation in prevalence in the different regions of the country
Alcohol Use Disorders in National Samples of Mexicans and Mexican-Americans
The authors show associations between immigration and alcohol disorders using data from the 1995 and 2000 U.S. National Alcohol Surveys and the 1998 Mexico National Household Survey on Addictions.

Cross-national prevalence and risk factors for suicidal ideation, plans and attempts
BACKGROUND: Suicide is a leading cause of death worldwide; however, the prevalence and risk factors for the immediate precursors to suicide - suicidal ideation, plans and attempts - are not wellknown, especially in low- and middle-income countries. AIMS: To report on the prevalence and risk factors for suicidal behaviours across 17 countries. METHOD: A total of 84 850 adults were interviewed regarding suicidal behaviours and socio-demographic and…
The Meanings of Emotional Ailments in a Marginalized Community in Mexico City
The population's conceptions about health are crucial to the development of any intervention strategy in the field of public health. We are interested in describing the sense adult inhabitants confer on emotional ailments in daily life. We used the Theory of Social Representations as a framework of reference and a multimethod perspective, which will enable us to recover the subjective experience of participants in the study, not only regarding em…
Prevalence of codependence in young women seeking primary health care and associated risk factors
Codependence as a relational problem that often, but not necessarily always, occurs in conjunction with familial alcoholism. Previous research has shown that various etiological factors resulting from recurring stressful circumstances experienced in childhood or adulthood may contribute to this relation. Another factor arises out of the "submission script" that may be assumed by women living within a culture that typically promotes unequal power …

Twelve-Month Prevalence of and Risk Factors for Suicide Attempts in the World Health Organization World Mental Health Surveys
OBJECTIVE: Although suicide is a leading cause of death worldwide, clinicians and researchers lack a data-driven method to assess the risk of suicide attempts. This study reports the results of an analysis of a large cross-national epidemiologic survey database that estimates the 12-month prevalence of suicidal behaviors, identifies risk factors for suicide attempts, and combines these factors to create a risk index for 12-month suicide attempts …
Cross-national differences in clinically significant cannabis problems
This study's most remarkable finding may be the similarity in occurrence of cannabis-related problems in this cross-national comparison within the Americas. Wide cross-national variations in estimated population-level cumulative incidence of cannabis use disorders may be traced to large differences in cannabis smoking prevalence, rather than qualitative differences in cannabis experiences. More research is needed to identify conditions that might…

Institutional stakeholder perceptions of barriers to addiction treatment under Mexico's drug policy reform
Mexico has experienced disproportionate drug-related harms given its role as a production and transit zone for illegal drugs destined primarily for the USA. In response, in 2009, the Mexican federal government passed legislation mandating pre-arrest diversion of drug-dependent individuals towards addiction treatment. However, this federal law was not specific about how the scale-up of the addiction treatment sector was to be operationalised. We t…
Association of Mental Disorders With Subsequent Chronic Physical Conditions
These findings suggest that mental disorders of all kinds are associated with an increased risk of onset of a wide range of chronic physical conditions. Current efforts to improve the physical health of individuals with mental disorders may be too narrowly focused on the small group with the most severe mental disorders. Interventions aimed at the primary prevention of chronic physical diseases should optimally be integrated into treatment of all…
The epidemiology of traumatic event exposure worldwide
Background Considerable research has documented that exposure to traumatic events has negative effects on physical and mental health. Much less research has examined the predictors of traumatic event exposure. Increased understanding of risk factors for exposure to traumatic events could be of considerable value in targeting preventive interventions and anticipating service needs. Method General population surveys in 24 countries with a combined …
