Each of the five items is rated on a 6-point Likert scale from 0 (= not present) to 5 (= constantly present). The theoretical raw score ranges from 0 to 25 and is transformed into a scale from 0 (worst thinkable well-being) to 100 (best thinkable well-being). Thus, higher scores mean better well-being.
The raw score is obtained by adding the figures in the boxes. The score range is from 0 to 25. It is recommended to administer the Major Depression (ICD-10) Inventory if the raw score is below 13 or if the patient has answered 0 to 1 to any of the five items. A score below 13 indicates poor well-being and is an indication for testing for depression under ICD-10.
In order to monitor possible changes in well-being, the percentage score is used. The percentage value is obtained by multiplying the score by 4. A 10% difference indicates a significant change.
