Scoring

To measure treatment outcome the sum of the ten items is used. A higher score signifies deeper depression. When using the scale to diagnose depression according to ICD-10, there are the following possibilities: * Mild depression: A score of 4 or 5 in two of the first three items. Plus a score of at least 3 on two or three of the last seven items. * Moderate depression: A score of 4 or 5 in two or three of the first three items. Plus a score of at least 3 on four of the last seven items. * Severe depression: A score of 4 or 5 in all of the first three items. Plus a score of at least 3 on five or more of the last seven items. * Major depression: The number of items is reduced to nine, as Item 4 is part of Item 5. Include whichever of the two items has the highest score (item 4 or 5). A score on at least five items is required, to be scored as follows: the score on the first three items must be at least 4, and on the other items at least 3. Either Item 1 or 2 must have a score of 4 or 5.
