The MDI (Major Depression Inventory) helps those patients whom either see themselves or whom may be seen by others as being depressed, mapping the extent of their feelings of depression over a 6 point scale and across 10 questions (with questions 8 and 10 measured in subparts).

Self-reporting of depressive feelings from the patient over the previous 2 weeks. This inventory can be used as part of the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders), which can also be categorized by 9 of the diagnostic criteria for Major Depression, which constitutes a separate algorithm. Whilst such a scale is useful to aid obtaining a sense of severity of depression, all patients must be able to receive extra support and resources and referral if needed, especially in cases of suicidal or psychotic thoughts, which must be screened for. Considering severity as a measure, the MDI score spans from 0 to 50 as each of the 10 questions can obtain a 0 to 5 score (including the subparts of question 8 and 10). Questions 8 and 10 parts a and b are scored for the highest mark obtained between the 2 alternatives, a and b. The values of each score 0 to 5 is shown below: Point Values +5= All the time +4= Most of the time +3= Slightly more than half the time +2= Slightly less than half the time +1= Some of the time 0= At no time Score interpretations: 20-24 indicate mild depression. 25-29 indicate moderate depression. ≥30 indicate severe depression.. Scores ≥30 indicate severe depression.

Do not use in isolation of supporting psychiatric assessment and without the provision of other supporting resources as needed.
