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 < 0.02), whereas the mental component summary (MCS-12) score had an ICC of 0.72 (95%CI: 0.49-0.84; p < 0.001). The PCS-36 score had an ICC of 0.88 (95%CI: 0.78-0.93; p < 0.001), and the MCS-36 score also had an ICC of 0.88 (95%CI: 0.78-0.93; p < 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.
