Age-of-onset and cumulative risk of mental disorders: A cross-national analysis of population surveys data based on 156,331 respondents from 29 countries

Information on frequency and timing of mental disorder onsets across the lifespan is of fundamental importance for public health planning.

Patterns and correlates of patient-reported helpfulness of treatment for common mental and substance use disorders in the WHO World Mental Health Surveys

Patient-reported helpfulness of treatment is an important indicator of quality in patient-centered care. We examined its pathways and predictors among respondents to household surveys who reported ever receiving treatment.

The associations between traumatic experiences and subsequent onset of a substance use disorder: Findings from the World Health Organization World Mental Health surveys

Exposure to traumatic events (TEs) is linked to substance use disorders (SUDs). Most studies focus on single TEs and countries. We used cross-national data to examine diverse TEs' associations with SUD onset and their variation over time.

Age of onset and cumulative risk of mental disorders: a cross-national analysis of population surveys from 29 countries

Updated data on the timing and frequency of mental disorder onsets is crucial for public health planning. This study updates and improves estimates of age-of-onset distributions, lifetime prevalence, and morbid risk from the 2007 cross-national surveys.

Development and evaluation of a risk algorithm predicting alcohol dependence after early onset of regular alcohol use

Early alcohol involvement increases the likelihood of alcohol dependence (AD). Early interventions can reduce this risk but may be costly. Developing a prediction model to target interventions at high-risk youth could enhance cost-effectiveness.

Findings From the World Mental Health Surveys of Civil Violence Exposure and Its Association With Subsequent Onset and Persistence of Mental Disorders

Understanding the association of civil violence with mental disorders is important for developing effective post conflict recovery policies.

Patterns, predictors, and patient-reported reasons for antidepressant discontinuation in the WHO World Mental Health Surveys

Despite their efficacy, many patients stop antidepressant medication (ADM) without a doctor's advice. This report examines patient-reported reasons, patterns, and predictors of ADM discontinuation.

Factors associated with satisfaction and perceived helpfulness of mental healthcare: a World Mental Health Surveys report

Mental health service providers are interested in patient perspectives. We examined rates and predictors of patient-reported satisfaction and perceived helpfulness in a cross-national survey of adults with DSM-IV disorders who sought mental health care.

Proof‐of‐concept of a data‐driven approach to estimate the associations of comorbid mental and physical disorders with global health‐related disability

The standard method of generating disorder‐specific disability scores has lay raters make rankings between pairs of disorders based on brief disorder vignettes.
