METHODS: Forty-nine patients with RA were used to evaluate test-retest reliability, and 100 consecutive RA patients were used for construct validity. Twenty-five RA patients, commencing with treatment on tumour necrosis factor (TNF) inhibitors, were evaluated before the start and after three months of therapy, to test responsiveness. The most important leisure activity (as judged by the patients) was used when evaluating reliability and validity. The perceived difficulty with each activity was scored from 0 to 10 (0 = able to perform activity without difficulty, 10 = unable to perform activity). RESULTS: Test-retest reliability indicated a good agreement (0.62-0.87) using weighted kappa.
