Abstract

Objectives To evaluate the correlation between the questionnaire of impact of Rheumatoid Arthritis (RAID: Rheumatoid Arthritis Impact Disease) and questionnaires for assessing disease activity judged by patient (RAPID-3: Routine Assessment of Patient Index Data 3, and RADAI-5: Rheumatoid Arthritis Disease Activity Index5) and composite indicesfor assessment of disease activity (DAS28-ESR: activity score of 28 joint disease activity index CDAI and clinical disease) in daily practice.

Methods A cross sectional study in patients with rheumatoid arthritis according to the2010 ACR/EULAR criteria was conducted. All patients completed the following questionnaires RAID, RADAI 5and RAPID-3. The DAS28-ESR and the CDAI were measured simultaneously. The reliabilitywas calculated by Cronbach's alpha and factorial analysis was performed. The correlation coefficient “tau” of Kendall was used to analyze the correlation between different instruments.

Results Thirty patients with RA were included. The mean age was51±11 years with a female predominance (80%). Time to complete the questionnaires was 30 seconds. The median for RADAI-5 was 3.9 (1.7 to 4.9), 4.05 for the RAPID-3 (1.91 to 5.13), 4.47 for the RAID (2.31 to 5.78).Cronbach's alpha was excellent for RADAI-5 (α=0.99), RAPID-3 (α=0.99) and RAID (α=0.99).

The “tau” concordance was 0.78, 0.76, 0.74, and 0.82 between RAID and respectively RAPID3, RADAI5, DAS28ESR, CDAI. (p<0.001 was highly significant for all variables).

Conclusions The reliability of the questionnaire RAID is as good ascomposite indices.The questionnaires showed a good agreement with each other and indices.
