Major Depression Inventory

 

NOTE: This content was prepared by J. de Waard (jdewaard@bart.nl).

 

Components: 10 questions, with responses on a 6-point Likert scale based on frequency of the past 14 days. Two (8 and 10) are subdivided into two subitems (a and b). Only the higher scores of the 2 subitems from 8 and 10 (either a or b) are included in the final analysis.

 

The instrument consists of 10 questions related to feelings over the past 2 weeks.

Response for the 10 Questions	Points
all of the time	5
most of the time	4
more than half of the time	3
less than half of the time	2
some of the time	1
at no time	0

 

For items 8 and 10, choose the subitem (a or b) with the highest score.

 

total score =

= SUM(points for all 10 items)

 

Interpretation:

• minimum total score: 0

• maximum total score: 50

• The higher the score, the greater the depression.

 

ICD-10 Criteria

 

Counting is based on the number of items with scores of 4 or 5 (frequencies "all of the time" or "most of the time").

 

Number of Items 1 to 3 with Score >= 4	Number of Items 4 to 10 with Score >= 4	Level of Depression
2	>= 2	mild
2	>= 4	moderate
3	>= 5	severe

 

DSM-IV Criteria

 

Counting is based on the number of items with scores of 4 or 5 (frequency all or most of the time).

 

The number of items is reduced from 10 to 9, since item 4 is considered a part of item 5. The higher score of the 2 (items 4 and 5) is used for the final score.

 

Number of Items 1 and 2 with Score >= 4	Number of All 9 Items with Score >= 4	Level of Depression
>= 1	>= 5	major
