Cross-cultural adaptation and validation of a French version of the Measure of Stroke Environment (MOSE) in stroke survivors in Sub-Saharan Africa.

PURPOSE To investigate the psychometric properties of the MOSE-Benin, a French-language version of the Measure of Stroke Environment (MOSE) for Sub-Saharan Africa. MATERIALS AND METHODS The original English version of the MOSE has been translated into French following the guidelines for cross-cultural adaptation. The resulting questionnaire (MOSE-Benin) was administered to a convenience sample of participants recruited in Benin, a French-speaking country. RESULTS Eighty-two stroke survivors (41 females; mean ± SD: 54.94 ± 11.6 years old) participated in the study. Internal consistency of each domain of the MOSE-Benin and the overall questionnaire was high (Cronbach's α: 0.78 to 0.92). Test-retest reliability was excellent (n = 31; ICC: 0.977 to 0.998). Overall, the standard error of measurement (SEM) and the minimum detectable change (MDC) showed very low values (SEM = 0.85; MDC = 2.35). Convergent validity demonstrated moderate correlations for the three domains in separate comparison respectively with the ACTIVLIM-Stroke questionnaire, the Participation Measurement Scale, and the communication domain of the Stroke Impact Scale (r or ρ: 0.42 to 0.54; p < 0.0001). CONCLUSION MOSE-Benin has good evidence regarding psychometric properties (i.e., content validity, convergent validity, internal consistency, and test-retest reliability) that can support its use for the assessment of perceived environmental barriers after stroke in a French-speaking Sub-Saharan African country, such as Benin.
