There are 4 subscales:
(1) breathlessness
(2) mood
(3) social
(4) concerns
The assignment of questions to the subscales is assumed to be the same as for the Sydney questionnaire.
(1) breathlessness (7) - questions 1 to 5, 15 and 16
(2) mood (5) - questions 6 to 10
(3) social (5) - questions 11 to 14 and 17
(4) concerns (5) - questions 11, 17 to 20
adjusted subscale =
= MEAN(score for questions in the subscale) * 2.5
adjusted total score =
= MEAN(score for all of the questions) * 2.5
Interpretation:
• minimum adjusted subscale or total score: 0
• maximum adjusted subscale or total score: 10
• The higher the score, the more severe the impact on the patient's quality of life.
