SUMMARY Introduction. The Back Pain Functional Scale is a scale to assess disability in Low Back Pain patients. The purpose of this study was to translate, culturally adapt and validate the BPFS from the original English language into Italian. Materials and methods. Translation and cultural adaptation have been performed following international guidelines. 170 italian-speaking subjects with low back pain were recruited; 58 of them also performed the re-test. Internal consistency was assessed by calculating Cronbach’s Alpha and test-retest reliability was assessed by calculat ing the Intraclass Correlation Coefficient (ICC). Exploratory factor analysis and was performed to assess the construct validity and the correlation with other clinical scales was observed through Pearson’s correlation coefficients. Results. High internal consistency (Cronbach’s Alpha = 0.912) and very good test-re test reliability (ICC = 0.956) were found. Pearson’s correlation coefficient showed statistically significant correlations (p < 0.01) with the BPFS, FRI and ODI. Conclusions. The Italian version of the BPFS showed with good reliability and construct validity. This scale can be considered for the assessment of functional disabil ity in subjects with LBP: short, intuitive and easy to understand. It can certainly be used for both clinical practice and research.
