[Development of rheumatoid arthritis functional handicap assessment questionnaire: preliminary study]

To construct a handicap assessment questionnaire for rheumatoid arthritis and to determine if the concept of "participation" can replace the one of "handicap".

Selection of daily life domains and items was based on the International Classification of Impairment Disability and Handicap "ICIDH" and on some others handicap epidemiological studies. The questionnaire was tested among rheumatoid arthritis patients. The relation between handicap and participation was investigated. Statistics analysis was performed with Systat.9 program. Spearman's correlation coefficient between 2 quantitative variables was examined.

Six among the 7 "ICIDH" domains were included in the questionnaire. Each of them was explored with many items. Forty-six items were included; each item was explored in 4 chapters:participation assessment with VAS (Visual Analogical Scale) before rheumatoid arthritis and during the study; difficulties: need of help, environment accessibility, patient's satisfaction, feeling of devalorization; patient's propositions;handicap assessment with VAS; other questions were added in some particular items. Thirty patients were included in the study (23 women), the average age was 51 years. Five patients didn't understand the meaning of "Handicap".This study allows us to eliminate 2 items, to add 2 others and to ameliorate 1 of them. Correlation between handicap and participation was moderate to bad.

This questionnaire allows to explore rheumatoid arthritis handicap. Each domain of the daily life can be assessed separately. The main difficulties are the length and the impossibility to be self-administered. Handicap and participation probably assess different concepts or are differently understood by patients.
