First Onset in Adulthood of Mental Disorders: Exposure to War . Non-war Childhood Adversities: A National Study.

Background: There is evidence that some childhood trauma increases the risk of the first onset of mental disorders and for the first time into adulthood. There are no studies that assessed whether exposure to war has this delayed long-term effect.

Objectives: To fill this gap by investigating the comparative roles of war and non-war trauma on the first onset of adulthood mood and anxiety disorders.

Inequality on the frontline: A multi-country study on gender differences in mental health among healthcare workers during the COVID-19 pandemic.

Healthcare workers (HCWs) were at increased risk for mental health problems during the COVID-19 pandemic, with prior data suggesting women may be particularly vulnerable. Our global mental health study aimed to examine factors associated with gender differences in psychological distress and depressive symptoms among HCWs during COVID-19. Across 22 countries in South America, Europe, Asia and Africa, 32,410 HCWs participated in the COVID-19 HEalth caRe wOrkErS (HEROES) study between March 2020 and February 2021.

Predictors and severity of probable acute stress disorder following the Beirut Port Blast.

Background: The Beirut Port Blast on August 4, 2020 is the largest (non-nuclear) explosion on record. St George Hospital University Medical Center (SGHUMC), a leading academic medical centre in Lebanon, adjacent to the Port, sustained a massive loss in lives and infrastructure.

Objective: The current study uses the baseline data of an ongoing longitudinal study to explore the prevalence, severity, and predictors of probable Acute Stress Disorder (ASD) among health workers at SGHUMC following the blast.

Association of Cohort and Individual Substance Use With Risk of Transitioning to Drug Use, Drug Use Disorder, and Remission From Disorder: Findings From the World Mental Health Surveys.

Importance: Limited empirical research has examined the extent to which cohort-level prevalence of substance use is associated with the onset of drug use and transitioning into greater involvement with drug use.

Objective: To use cross-national data to examine time-space variation in cohort-level drug use to assess its associations with onset and transitions across stages of drug use, abuse, dependence, and remission.

Design, Setting, And Participants: The World Health Organization World Mental Health Surveys carried out cross-sectional general population surveys in 25 countries using a consistent research protocol and assessment instrument.

Parent psychopathology and offspring mental disorders: results from the WHO World Mental Health Surveys.

Background: Associations between specific parent and offspring mental disorders are likely to have been overestimated in studies that have failed to control for parent comorbidity.

Aims: To examine the associations of parent with respondent disorders.

Method: Data come from the World Health Organization (WHO) World Mental Health Surveys (n = 51 507).

DSM-IV personality disorders in the WHO World Mental Health Surveys.

Background: Little is known about the cross-national population prevalence or correlates of personality disorders.

Aims: To estimate prevalence and correlates of DSM-IV personality disorder clusters in the World Health Organization World Mental Health (WMH) Surveys.

Method: International Personality Disorder Examination (IPDE) screening questions in 13 countries (n = 21 162) were calibrated to masked IPDE clinical diagnoses.

Effectiveness and specificity of a classroom-based group intervention in children and adolescents exposed to war in Lebanon.

The purpose of this study was to examine the effectiveness and specificity of a classroom-based psychosocial intervention after war. All students (n=2500) of six villages in Southern Lebanon designated as most heavily exposed to war received a classroom-based intervention delivered by teachers, consisting of cognitive-behavioural and stress inoculation training strategies. A random sample of treated students (n=101) and a matched control group (n=93) were assessed one month post-war and one year later.
