Research into the Dutch questionnaire for measuring inflammatory activity in patients with rheumatoid arthritis
- Period:
- July 2024
- Research domain:
- Clinical domain-specific and cross-domain research

Why do we do this?
Ninety per cent of people with rheumatoid arthritis (RA) experience foot problems as a result of inflammation in the foot joints and surrounding tissue. Early detection of inflammatory activity in the feet is essential, as prolonged inflammatory activity can lead to unnecessary and permanent deterioration of foot condition. The Rheumatoid Arthritis Disease Activity Index-5 (RADAI-F5) is an English-language questionnaire that measures inflammatory activity in the feet. This English-language questionnaire consists of five items that enable inflammatory activity in the feet in RA to be assessed reliably and quickly. The questionnaire has been translated into Dutch and optimised with the help of 11 RA patients and several experts. Its applicability in the Dutch context appears highly feasible, but this must first be tested amongst RA patients. That is why this study has been set up.
How should we handle this?
This study was carried out by researchers from the podiatry research group. Within Rondom, several patients with RA were invited to take part in this study.
What have we found?
The English-language RADAI-F5 questionnaire has been translated into Dutch and assessed for internal consistency and retest reliability. These were found to be good. The researchers are currently submitting a report on this study for publication. The conclusion is that the Dutch RADAI-F5 can now be put into use.
Impact and follow-up actions
The Dutch RADAI-5 can be used in podiatry practice to measure inflammatory activity in patients with RA
