- | The Type-D questionnaire used in Lifelines contains 14 items from the DS14((Denollet, J. (2005) DS14: Standard Assessment of Negative Affectivity, Social Inhibition, and Type D Personality. Psychosomatic Medicine 67: 89-97)), which includes seven items that refer to negative affectivity (items 2, 4, 5, 7, 9, 12, 13), and seven items that refer to social inhibition (items 1 (reversed), 3 (reversed), 6, 8, 10, 11, 14).\\ | + | The Type-D questionnaire used in Lifelines contains 14 items from the DS14 (1-14), and 6 additional items (15-21).\\ |
- | The Type-D questionnaire in Lifelines contains 6 additional items (15-21).\\ | + | Participants were asked to rate how well the statements describe their personality on a 5-point [[https://en.wikipedia.org/wiki/Likert_scale|Likert scale]] which correspond to 0 (false) to 4 (true) points (note that Lifelines enumerates the options from 1 to 5 rather than 0 to 4).\\ |
- | Participants were asked to rate how well the statements describe their personality on a 5-point [[https://en.wikipedia.org/wiki/Likert_scale|Likert scale]] which correspond to 0 (false) to 4 (true) points (except the reversed items!). | + | |
- | People who score 10 points or more **both** scales of the DS14 are classified as Type D.\\ | + | The Negative Affectivity and Social Inhibition scales van be used as continuous variables to assess each of these two personality traits in their own right. Scores on both scales range from 0-28, and can be calculated as follows: |
+ | * **Negative Affectivity** = sum of scores on items 2 + 4 + 5 + 7 + 9 + 12+ 13 | ||
+ | * **Social inhibition** = sum of scores on items 1 [//reversed//] + 3 [//reversed//] + 6 + 8 + 10 + 11 + 14 | ||
+ | |||
+ | Participants are classified as Type D if both Negative Affectivity is greater or equal than to 10 and Social Inhibition is greater than or equal to 10.\\ | ||
+ | |||
+ | The following table from (1) can be used for the interpretation of the raw scores on both scales. The interpretation differs for men and women regarding Negative Affectivity, but not Social Inhibition.\\ | ||
