Aplicabilidade do questionário de qualidade de vida relacionada à saúde - the 12-Item Short-Form Health Survey - em pacientes portadores de esclerose sistêmica progressiva

Abstract: 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 we… Show more

“…Ware and colleagues [39], however, reported higher ICC (0.89) for the PCS-12 but slightly lower (0.75) for MCS-12 when compared to our findings. In contrast, lower ICC values for the PCS-12 (0.47) and MCS-12 (0.72) were reported for the Brazilian version in patients with progressive systemic sclerosis [66]. The variations in the values of ICC across studies can be a result of variations in the population sampled, methods of assessments and intervals between assessments.…”

“…Quality of life was verified by the Medical Outcome Study Short Form12-Item (SF-12) 15 ; the handgrip strength was measured using the Jamar dynamometer (measured in kg); and to assess wrist and hand pain, the Visual Analogue Scale was used. In the assessment of grip strength and hand mobility, data from the dominant hand were considered.…”

“…The sample size calculation was based on other studies conducted in Brazil and investigating the cultural adaptation and (9) the Airways Questionnaire 20, (10) and the Medical Outcomes Study 12-item Short-form Health Survey. (11) The sample size calculation was also based on recommendations for obtaining a lower margin of error. (12) Continuous variables are expressed as means and standard deviations.…”
