Multiple system atrophy (MSA)
has considerable impact on
health-related quality of life. The MSA health-related Quality of Life scale
(MSA-QoL) is a patient-reported questionnaire, which has been recently designed
to evaluate the quality of life in MSA. The objective of the present study was to
validate the French version of the MSA-QoL questionnaire. METHODS: One hundred
and thirty-six consecutive MSA patients were included in the study. Four patients
with more than 10% missing responses were excluded from the final analysis. Data
quality, scaling assumptions, acceptability, reliability and validity were
assessed similar to the original validation of the English version. RESULTS:
Missing responses were low, item and subscale scores were evenly distributed and
floor and ceiling effects were negligible. Item-total correlations were higher
than the recommended greater than 0.30 and internal consistency was high for all
subscales. Test-retest reliability was good for all subscales. Validity was
supported by moderate interscale correlations between the subscales and the
predicted correlations with other scales assessing motor disability, activities
of daily living, quality of life and mood. DISCUSSION: The French version of the
MSA-QoL displays robust psychometric properties similar to the English version.
CONCLUSION: The French version of MSA-QoL seems suitable for assessing quality of
life in French speaking MSA patients.
