Translation, cross-cultural adaptation, and validation of the 10-item spine functional index (SFI-10) in the Brazilians with musculoskeletal spine disorders.

ABSTRACT:

Purpose

To translate and cross-culturally adapt the Spine Functional Index (SFI) into Brazilian Portuguese (SFI-Br) in individuals with musculoskeletal spine disorders.

Methods

Participants (n=194) answered the Numerical Pain Rating Scale (NPRS), 36-item Short-Form Health Survey (SF-36), Roland-Morris Disability Questionnaire for General Pain (RMDQ-g), and SFI-25 incorporating the SFI-10. Structural validity, from confirmatory factor analysis (CFA), used comparative fit index (CFI), Tucker-Lewis index (TLI), root mean square error of approximation (RMSEA), and chi-square/degrees of freedom (DF). The best structure was considered from the lower values of the Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC). Construct and criterion validity used Spea
