The major depression index (MDI) addresses the most common symptoms associated with depressive disorder. This is a screening tool for depression based on the most common clinical signs of depressive disorder.
The MDI evaluates four groups of day to day activities, feelings and reactions that are characteristic to depressive disorder.
When answering the questions, please consider your experiences from the past 2 weeks.
As a screening system, the MDI checks for the existence and severity of depression based on the symptoms the subject experiences and on their frequency.
The final score range between 0 and 50, where 0 indicates no depression and 50 indicates severe depression.
There are three cut off points at scores of 20, 25 and 30, that create four categories of screening outcomes:
MDI score
Depression severity 0 - 19 None • 20 - 24 Mild • 25 - 29 Moderate • ≥30 Severe
