objective: to evaluate the applicability of the 12-item short-form health survey (sf-12) as an instrument to measure health-related quality of life in a sample of patients with progressive systemic sclerosis (pss) through the analysis of its reproducibility and its correlation with functional and clinical parameters. methods: a test-retest reproducibility study for the comparative analysis of the intraclass correlation coefficients (iccs) of the sf-12 and the sf-36. a total of 46 patients diagnosed with pss were studied, regardless of the presence of respiratory symptoms. results: the physical component summary 12 (pcs-12) score had an icc of 0.47 (95%ci: 0.05-0.71; p %26lt; 0.02), whereas the mental component summary (mcs-12) score had an icc of 0.72 (95%ci: 0.49-0.84; p %26lt; 0.001). the pcs-36 score had an icc of 0.88 (95%ci: 0.78-0.93; p %26lt; 0.001), and the mcs-36 score also had an icc of 0.88 (95%ci: 0.78-0.93; p %26lt; 0.001). conslusion: the sf-12 is a reliable instrument for measuring health-related quality of life in patients with pss, since it has been proven to be reproducible. however, this version of the sf-12 should only be used in clinical research settings.
