Abstract BACKGROUND: Little is known about the epidemiology of adult attention-deficit hyperactivity disorder (ADHD). AIMS: To estimate the prevalence and correlates of DSM-IV adult ADHD in the World Health Organization World Mental Health Survey Initiative. METHOD: An ADHD screen was administered to respondents aged 18-44 years in ten countries in the Americas, Europe and the Middle East (n=11422). Masked clinical reappraisal interviews were administered to 154 US respondents to calibrate the screen. Multiple imputation was used to estimate prevalence and correlates based on the assumption of cross-national calibration comparability. RESULTS: Estimates of ADHD prevalence averaged 3.4\% (range 1.2-7.3\%), with lower prevalence in lower-income countries (1.9\%) compared with higher-income countries (4.2\%). Adult ADHD often co-occurs with other DSM-IV disorders and is associated with considerable role disability. Few cases are treated for ADHD, but in many cases treatment is given for comorbid disorders. CONCLUSIONS: Adult ADHD should be considered more seriously in future epidemiological and clinical studies than is currently the case.
