Translation and validation of Neck Bournemouth Questionnaire to Brazilian Portuguese.
OBJECTIVE
To translate the Neck Bournemouth Questionnaire to Brazilian Portuguese, cross-culturally adapt, and to verify its validity and its reliability.


METHODS
The development of the Brazilian version of Neck Bournemouth Questionnaire (Brazil-NBQ) was based on the guideline proposed by Guillemin. The applied process consisted of translation, back-translation, committee review and pre-test. Sixty-one volunteers presenting neck pain participated in this study. Thirty-five of them participated during pre-testing phase to verify the instrument comprehension, and the remaining 26 took part during psychometric analysis. Psychometric evaluation included interrater and intrarater reliability and construct validity (correlation among Brazil-NBQ, SF-36, Numerical rating score and Neck Disability Index).


RESULTS
Some terms and expressions were changed to obtain cultural equivalence for Brazil-NBQ during the translation phase. The NBQ showed an intrarater ICC of 0.96 and interrater ICC of 0.87. Construct validity analysis showed moderate correlations with SF-36 and strong correlation with Numerical rating score and Neck Disability Index.


CONCLUSIONS
Neck Bournemouth Questionnaire was translated and culturally adapted to Portuguese language, and it demonstrated to be valid and reliable to evaluate patients' neck pain.
