The Major Depression Inventory for diagnosing according to DSM-5 and ICD-11: Psychometric properties and validity in a Swedish general population.

Hopelessness and the MDI items had good psychometrics. MDI for DSM-5 and ICD-11 had similar validity as for DSM-IV and ICD-10. We recommend that MDI is updated to DSM-5 and ICD-11 by adding a hopelessness item.
