(2) mental health (3): energy, depression, overall quality of life
(3) role functioning (4): seizure worry, work, driving, social limits
Points are assigned from 1 to 5 based on the frequency or severity during the previous 4 weeks.
QOLIE-10 score =
= SUM(points for all 10 questions)
subscore for epilepsy effects =
= SUM(points for items #4 + #7 + #8)
subscore for mental health =
= SUM(points for items #1 + #2 + #10)
subscore for role functioning =
= SUM(points for items #9 + #5 + #6 + #3)
Interpretation:
• minimum total score: 10
• maximum total score: 50
• The higher the score, the poorer the expressed quality of life.
