Developed	1970s–1990s
Developer	World Health Organization; US National Institute of Mental Health; WHO Collaborating Centres
Type	Structured diagnostic interview
Purpose	Psychiatric diagnosis for research and epidemiology

Composite International Diagnostic Interview is a structured diagnostic interview designed for assessing mental disorders across diverse populations. It was created to enable standardized diagnosis in epidemiological studies and clinical research, aiming to generate comparable data across countries and settings. The instrument links to major multinational initiatives, psychiatric research centers, public health agencies, and global health surveys.

History

The instrument originated from collaborations among the World Health Organization, the United States National Institute of Mental Health, and academic centers such as the Johns Hopkins University, the Harvard Medical School, the University of Michigan, and the University College London. Early field use occurred in multicenter projects including the WHO World Mental Health Survey Initiative, the Epidemiologic Catchment Area Study, and large cohort efforts like the National Comorbidity Survey. Influential contributors and working groups included researchers affiliated with the Columbia University, the University of California, Los Angeles, the McGill University, the Karolinska Institute, and the Australian National University. Funding and dissemination involved agencies such as the National Institutes of Health, the Wellcome Trust, and the European Commission research programs.

Structure and Modules

The interview is organized into modules covering diagnostic categories derived from classifications such as the International Classification of Diseases and the Diagnostic and Statistical Manual of Mental Disorders. Modules align with conditions studied in projects like the Global Burden of Disease analyses and instruments used by institutions including the Centers for Disease Control and Prevention, the NIMH Genetics Initiative, and the European Study of the Epidemiology of Mental Disorders. Content development drew on expertise from departments at the University of Oxford, the Imperial College London, the Karolinska Institutet, and the University of Toronto. The modular format facilitated comparison with other assessment tools used by groups such as the American Psychiatric Association, the Royal College of Psychiatrists, the Canadian Psychiatric Association, and the National Health Service research units.

Administration and Scoring

Administration methods include interviewer-led, computer-assisted, and self-report formats, employed in studies run by organizations like the World Bank, the Pan American Health Organization, and the United Nations Children's Fund. Training programs were developed with academic partners such as the London School of Hygiene & Tropical Medicine, the Yale School of Medicine, and the Massachusetts General Hospital. Scoring algorithms and diagnostic outputs were compared to clinical assessments used at centers like the Mayo Clinic, the Cleveland Clinic, the Mount Sinai Hospital, and the Karolinska University Hospital; statistical analysis frameworks referenced work from the Institute for Health Metrics and Evaluation and the RAND Corporation.

Validity and Reliability

Psychometric evaluations referenced validation studies conducted at institutions including the University of California, San Diego, the University of Pittsburgh, the University of Melbourne, and the National Institute of Mental Health (USA). Cross-cultural reliability was examined in multinational samples from countries represented by the Ministry of Health (Brazil), the Ministry of Health (India), the Chinese Center for Disease Control and Prevention, and the South African Medical Research Council. Comparative validity work involved collaborations with specialty centers such as the Institute of Psychiatry, Psychology and Neuroscience, the Stanford University School of Medicine, and the Max Planck Institute for Psychiatry.

Versions and Translations

Multiple editions and revisions were produced in concert with bodies like the World Health Organization Regional Office for Europe, the World Health Organization Regional Office for the Western Pacific, and national research councils including the National Health and Medical Research Council (Australia). Translations and cultural adaptations were carried out for use in languages and contexts represented by partners from the Universidad Nacional Autónoma de México, the Peking University, the University of Cape Town, the University of Tokyo, and the Universidade de São Paulo. Comparative projects included teams from the European Union research networks, the African Mental Health Research Initiative, and the Latin American Epidemiological Consortium.

Uses and Applications

The instrument has been employed in large-scale epidemiological surveys such as the World Mental Health Survey Initiative, population cohort studies like the UK Biobank, and national surveys commissioned by the National Center for Health Statistics, the Australian Bureau of Statistics, and the Statistics Canada. Clinical research applications occurred at specialty centers including the Addiction Research Center, the Mood Disorders Program at Columbia University, the Anxiety Disorders Clinic at McLean Hospital, and veterans' health research at the United States Department of Veterans Affairs. Policy and burden estimates have informed reports produced by the World Health Organization, the Global Fund, and the Organisation for Economic Co-operation and Development.

Criticisms and Limitations

Critiques have arisen from researchers at institutions such as the London School of Economics, the University of California, Berkeley, the University of Maastricht, and the University of Edinburgh regarding cultural equivalence and diagnostic thresholds. Limitations noted in methodological reviews by groups like the Cochrane Collaboration, the National Institute for Health and Care Excellence, and the Agency for Healthcare Research and Quality include concerns about interviewer effects, translation fidelity, and applicability in clinical versus community settings. Debates involving scholars from the Harvard School of Public Health, the Yale School of Public Health, and the Johns Hopkins Bloomberg School of Public Health focus on comparability with other structured interviews used by the American Psychiatric Association and international diagnostic committees.
