French cross-cultural adaptation of the Health Utilities Indexes XXXX (HUI2) and 3 (HUI3) classification systems. Clinical and Economic Working Groups.

@entity1 @entity26646
The McMaster Health Utilities Indexes @entity26646 (HUI2) and 3 (HUI3) are multiattribute health classification systems, for which multiattribute preference functions have been developed in Canada. They provide a comprehensive instrument for use in economic evaluations and population health survey studies. This paper reports on the first results on the adaptation of the HUI2 and HUI3 systems cross-culturally and the assessment of the validity and reliability of the French self-report questionnaire in different @entity1 populations. The cross-cultural adaptation included translation, backtranslations, an expert consensus meeting and pre-test with a few @entity1 and healthy subjects in order to produce a conceptually equivalent French version of the 15 question self-report questionnaire and the HUI2 and HUI3 classification systems. Different groups of @entity1 attending specialized clinics (n = 709) completed the questionnaire and another generic questionnaire (the Sickness Impact Profile (SIP)) for validity assessment. Physicians and @entity1 were also asked for a global subjective assessment of the @entity1 's health status. The French questionnaire was well received by the @entity1 . The criterion and convergent validities of both classification systems (correlations with the @entity1 ' and physicians' assessments and with the responses to the SIP questionnaire) were satisfactory. The internal consistency was acceptable too (Cronbach's alpha = 0.81), as was the 3 day test-retest reproducibility. These first results authorize careful use of the 15 question self-report questionnaire in French. An assessment of the multiattribute preference function for the HUI3 system in France will be the study's next objective.
