About

The Major Depression Inventory (MDI) is a self-report mood questionnaire developed by the World Health Organisation by Professor Per Bech, a psychiatrist based at Frederiksborg General Hospital in Denmark. The MDI differs from many other self-report questionnaires because it is free of charge, translated into seven languages, can use for a ICD-10 or DSM-IV diagnosis of clinical depression, and estimate symptom severity (mild, moderate, and severe).
