total raw score =
= SUM(points for all 5 items)
adjusted total score to range from 0 to 100 =
= (total raw score) * 4
Interpretation:
• minimum score: 0
• maximum score: 25
• 0 represents the worst possible and 25 represents the best possible quality of life.
• The adjusted total score indicates the percentage of the best possible quality of life that the patient is experiencing.
• A score below 13 suggests poor well-being. The patient should be tested for depression under ICD-10.
• It is recommended to administer the Major Depression (ICD-10) Inventory if:
(1) the raw score is below 13, OR
(2) if the patient has answered 0 to 1 to any of the five items.
Modification:
(1) In the implementation an optional box has been added in which the pretest probability for depression in the tested person or tested population can be added. A post test probability is represented using the Likelihood ratio’s for this test
(Evidence-Based Medicine, 2003).
Limitation:
• I don't know many people who would score a 4 or 5 on the questions. In my experience many adults would have a total score in the 10 to 15 range.
• I personally would modify the wording of the fourth item from "some of the time" to "rarely" or "infrequently".
