Abstract
Methods
After having translated LEIPAD in accordance with guidelines, we studied psychometric properties: reliability and construct
validity—factor analysis, relationships between items and scales, internal consistency, concurrent validity with the Medical
Outcome Study Short-Form 36 and known-groups validity.
validity—factor analysis, relationships between items and scales, internal consistency, concurrent validity with the Medical
Outcome Study Short-Form 36 and known-groups validity.
Results
The results obtained in a sample of 195 elderly from the general population showed very good acceptability, with response
rates superior to 93 %. Exploratory factor analysis extracted eight factors providing a multidimensionality structure with
five misclassifications of items in the seven theoretical scales. Good internal consistency (Cronbach’s alpha ranging from
0.73 and 0.86) and strong test–retest reliability (ICCs higher than 0.80 for six scales and 0.70 for one) were demonstrated.
Concurrent validity with the SF-36 showed small to strong expected correlations.

Conclusion
This first evaluation of the French version of LEIPAD’s psychometric properties provides evidence in construct validity and
reliability. It would allow HRQoL assessment in clinical and common practice, and investigators would be able to take part
in national and international research projects.
