How to score it
The scoring of each answer is:
(a) 3
(b) 2
(c) 1
(d) 0
The score is calculated by summing the score of each question resulting in a possible maximum of 15 and a minimum of 0. The higher the score, the more the quality of life is impaired.
We would recommend that if one item is not answered, that item should be scored zero and the score for that completion would be the sum of the scores of the other four items (not adjusted).
If more than one item is not answered, the questionnaire cannot be scored.
