  • Patterns and predictors of the transition between minimally adequate treatment and effective treatment coverage for mental disorders

    Open AccessAlan E Kazdin, Kazdin Ae et al.ARTICLEInternational Journal of Mental…2026

    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…

    Open AccessJohn J Mcgrath, Ali Al-Hamzawi et al.ARTICLEThe Lancet Psychiatry2023

    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…

  • Socio-economic variations in the mental health treatment gap for people with anxiety, mood, and substance use disorders

    Open AccessSara Evans-Lacko, Sergio Aguilar‐gaxiola et al.ARTICLEPsychological Medicine2018

We examine this gap by socio-economic status (SES; indicated by family income and respondent education) and service sector in a cross-national analysis of community epidemiological survey data. Methods Data come from 16 753 respondents with 12-month DSM-IV disorders from community surveys in 25 countri…

    Open AccessJordi Alonso, Zhaorui Liu et al.ARTICLEDepression and Anxiety2018

We estimated, among individuals with a 12-month DSM-IV (where DSM is Diagnostic Statistical Manual) anxiety disorder in 21 countries, the proportion who (i) perceived a need for treatment; (ii) received any treatment; and (iii) received possibly adequate treatment. METHODS: Data from 23 community surveys…

Method The World Health Organization World Mental Health Surveys were used to examine the associations of mental disorders with college entry and attrition by comparing college students ( n = 1572) and non-students…

    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 …
