VALIDACIÓN TRANSCULTURAL DE UN CUESTIONARIO PARA EVALUAR EL DOLOR DE ESPALDA EN NIÑOS

ABSTRACT

Objective:

To validate the cross-cultural adaptation of the English version of theYoung Spine Questionnaire (YSQ) to Portuguese. The questionnaire enables the evaluation, in children, of back pain prevalence and frequency, restrictions on activity, care-seeking behavior, and the influence that the parents’ manifestations of back pain can have.

Method:

The research was conducted in a school setting, with a sample of 128 children aged 9 to 12 years (63 males and 65 females). The questionnaire was completed at two different moments. Test-retest reliability was used to evaluate the degree of reproducibility, and the intraclass correlation coefficient (ICC) between the two sets of observed values was estimated for p<0.05. Cronbach’s alpha coefficient was used to assess the degree of reliability (internal consistency) of the questionnaire.

Results:

For most of questions, the ICC ranged between 0.527 and 0.870, with reasonable to excellent correlation to the reproducibility index. The exceptions were foritem c) in two of the first three questions, where the ICC values (0.149 and 0.277) were lower. The value of Cronbach’s alpha calculation was 0.8, indicating high internal consistency.

Conclusion:

It was demonstrated that the cross-cultural adaptation of the YSQ had content validity, was well-understood, and suitable for use in studies with Portuguese children between 9 and 12 years of age. Level of evidence II; Development of diagnostic criteria.
