The investigators will use the Short Form-12 Quality of Life Scale, which is an abbreviated version of the Medical Outcomes Study Short-Form General Health Survey, with only 12 of the 36 questions that can save a lot of time. It is a generic questionnaire that makes it possible to compare groups of subjects with different pathologies. It measures eight aspects of quality of life that reflect
World Health Organization (WHO) definition of quality of life: general and mental health, physical and social functioning, physical and emotional health, pain and vitality.
Compared to the Short Form-36, the Short Form-12 has the advantage of being shorter, less time-consuming, thus easier for the evaluator and better tolerated by patients. Its results are correlated with those of the Short Form-36.
The Short Form-12 allows to obtain two scores (between 0 and 100, calculated thanks to an algorithm):
- a score of quality of mental and social life
- and a physical quality of life score.
