“…The RMDQ is recommended to be used in combination with other measures when low back pain is associated with psychological or social problems. Compared with RMDQ, the BPFS has better internal consistency, test-retest reliability, and point estimate of susceptibility to change, suggesting its superiority over RMDQ (18,22,29). However, we did not use RMDQ for the assessment of convergent validity assuming a better correlation between BPFS and FRI.…”

“…In the Turkish version of the questionnaire Maras et al (18) recruited only patients with chronic low back pain in order to obtain a homogeneous group. Tests by Kaiser Meyer Olkin and Bartlett showed that the sample was suitable and adequate for factorial analysis, which revealed that the BPFS had a single factor structure.…”

“…naire takes less than 5 minutes for administration and less than 30 seconds for final scoring (16). This scale has been translated, validated and culturally adapted in Persian and Turkish (17,18). The purpose of this study is to translate and culturally adapt the BPFS for Italian-speaking subjects with LBP, and to assess the validity and reliability of the BPFS.…”

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 calculating 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-retest 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 disability in subjects with LBP: short, intuitive and easy to understand. It can certainly be used for both clinical practice and research.

“…This consequence is consistent with results of BPFS in other languages. [6][7][8] Several limitations of the study should be noted. First, although simplified Chinese is the official language of China, China is multi-ethnic, most of which have their own language.…”

Study Design. A cross-sectional study. Objective. To translate and cross-culturally adapt back pain function scale (BPFS) into a simplified Chinese version (SC-BPFS), and evaluate the reliability and validity of SC-BPFS in patients with low back pain. Summary of Background Data. The BPFS is a reliable and valid evaluation instrument for low back pain. However, simplified Chinese version of BPFS has not been validated. Methods. Cross-cultural adaptation was performed according to the internationally recognized guidelines of the American Academy of Orthopaedic Surgeons Outcome Committee. Onehundred and sixty-two participants with low back pain (LBP) were included in this study. Reliability was tested based on testretest reliability and internal consistency. We calculated Cronbach alpha and intra-class correlation coefficient (ICC). Construct validity was analyzed by evaluating the correlations between SC-BPFS and the Oswestry disability index (ODI), the visual analogue scale (VAS), and the short form (36) health survey (SF-36).Results. The original version of the BPFS was cross-culturally well adapted and translated into simplified Chinese. Each item of the SC-BPFS was properly responded and correlated with the total items. SC-BPFS had good reliability (Cronbach alpha ¼ 0.847, intra-class correlation coefficient [ICC] ¼ 0.891, 95% confidence interval [CI] 0.864-0.914). Elimination of any one item in all did not result in a value of Cronbach alpha of <0.80. SC-BPFS had a high correlation with ODI (0.712, P < 0.01) and a moderate correlation with VAS (0.484, P < 0.01). And it was also fairly to very well correlated with physical domains of SF-36 (0.334-0.632, P < 0.01), and not correlated with mental domains of SF-36 (0.022-0.119, P > 0.05). Conclusion. SC-BPFS demonstrated outstanding acceptability, internal consistency, reliability, and construct validity, and could be recommended for patients with LBP in Mainland China.

BACKGROUND: Translation and validation of important scales in other languages reduce bias in reporting the functional status of the patient. OBJECTIVE: To translate the Back Pain Functional Scale into Urdu (BPFSu), adapt it for use in other cultures, and evaluate its psychometric properties. METHOD: According to Beaton guidelines, translation and cultural adaption was carried out. On 100 Urdu-literate men and women aged 18–60 years with lower back pain, the final BPFSu was assessed for psychometric qualities. First at baseline and again after 7 days, participants completed the BPFSu, the Functional Rating Index (FRI), and the Numeric Pain Rating Scale (NPRS). RESULTS: Internal consistency of the BPFSu was excellent (Cronbach’s alpha: 0.937). No floor and ceiling effects were found Excellent test-retest reliability (ICC = 0.882, CI 95%; 0.830–0.919) was achieved. Spearman correlation coefficient showed criterion validity with the NPRS (rho =â⁢⁢0.701, p⩽ 0.001) and Pearson correlation coefficient showed construct validity with the FRI (r=â⁢⁢0.740, p⩽ 0.001). The minimum detectable changes were 9.96, while the standard error of measurement was 3.6. CONCLUSION: The BPFSu is a valid and reliable instrument for assessing physical function in individuals experiencing low back discomfort.
