NCT ID NCT07617558
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study checks whether two short questionnaires can accurately measure physical fitness in children aged 10–18 with juvenile idiopathic arthritis or familial Mediterranean fever. Researchers will compare the questionnaire results with standard fitness tests. If the questionnaires work well, doctors could quickly assess fitness without special equipment, helping to create early exercise plans.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
It is generally recommended that the sample size for validity and reliability studies be 5 to 10 times the total number of items (30). In light of this information in the literature, and given that the International Physical Fitness Questionnaire (IPFQ) and the Self-Perceived Health-Related Physical Fitness Questionnaire for Children (SPFQ-C) have a total of 14 items, the sample size for our study was determined to be 98 participants. Consequently, we plan to include a minimum of 100 patients diagnosed with JIA or FMF in our study. Participants will be recruited from individuals who are being followed up at the Pediatric Rheumatology Subdivision of the Department of Internal Medical Sciences at Istanbul University Faculty of Medicine and who meet the inclusion criteria.
