OBJECTIVE: To adapt the SS-QoL into French and test its psychometric properties.
METHODS: Seventy-seven patients from a population-based registry were enrolled 3
months after their stroke. SS-QoL, NIHSS score, Barthel index, HAD, FSS, SF-36
scales, and MMSE were administered at enrolment. SS-QoL was re-administered at 15
days and 2 months. Internal consistency was assessed by Cronbach's alpha
coefficients, factorial validity by an exploratory factor analysis and external
validity by Mann-Whitney test and Spearman's correlations (rho), comparing SS-QoL
scores with those obtained from established scales. Reliability was assessed by
intra-class correlation coefficients (ICC) and responsiveness by standardized
effect sizes (ES). RESULTS: Test-retest and inter-observer reliabilities were
excellent (ICC> 0.88). Internal consistency was acceptable (alpha= 0.65-0.91),
except for the Personality domain (alpha= 0.58). Factor analysis individualized
eight homogenous axes. SS-QoL scores were different between groups opposed by
their modified Rankin score at enrolment or their overall quality of life
compared with pre-stroke status (p < 0.001). Ten of the twelve domains correlated
moderately (rho> 0.35) to strongly (rho> 0.5) with established measures. Nine
domains were mildly to moderately responsive to change (ES> 0.3). CONCLUSION: The
French version of the SS-QoL is a valid, reliable and moderately responsive
instrument.
