The Activities of Daily Living Scale of the Knee Outcome Survey
(KOS-ADLS) is a joint-specific questionnaire measuring functional limitation
experienced by individuals with knee disorders. The original English version of
the KOS-ADLS has been shown to be highly reliable and responsive to change. The
purpose of this study was to perform a translation and cross-cultural adaptation
of the original version of the KOS-ADLS questionnaire into French and to validate
this French version of the questionnaire. METHOD: In accordance with standard
procedure, the original version of the KOS-ADLS was translated and
cross-culturally adapted into French. Once the final French version of the
KOS-ADLS was developed, it was subjected to further psychometric evaluation with
76 individuals with knee disorders. Each participant completed the KOS-ADLS on
three occasions: at baseline, two days later to evaluate test-retest reliability,
and four weeks later to evaluate responsiveness. Symptoms and function-oriented
construct questions were also completed to evaluate construct-convergent and
known-group validity. RESULTS: The cross-cultural adaptation procedure revealed
no major problems with content or language. The French version of the KOS-ADLS
showed excellent test-retest reliability with low measurement error (intraclass
correlation coefficient = 0.92, minimal detectable change = 8.3), as well as high
responsiveness (standardized response mean = 1.41; clinically important
difference = 13.6). Further, it discriminates between different levels of
self-rated or clinician-rated knee function. CONCLUSIONS: The French version of
the KOS-ADLS is a reliable, valid and responsive questionnaire for the assessment
of functional limitation in individuals with musculoskeletal knee disorders.
