Brazilian version of the OSTRC Questionnaire on health problems (OSTRC-BR): translation, cross-cultural adaptation and measurement properties.

ABSTRACT:

Background

The Oslo Sports Trauma Research Center - Questionnaire on Health Problems (OSTRC-QHP) has been shown to be a valid and reliable questionnaire for monitoring athletes with acute, overuse, and illness problems.

Objectives

To translate and cross-culturally adapt the OSTRC-QHP into Brazilian-Portuguese (OSTRC-BR), and investigate the measurement properties of this version.

Methods

The original (Norwegian) questionnaire was translated and culturally adapted following existing guidelines. Measurement properties of the OSTRC-BR were investigated in 134 athletes followed for 13 weeks. Reliability was analyzed via internal consistency and test-retest reliability. Responsiveness was assessed by effect size (ES) estimations, correlation of the OSTRC-BR severity score with the Global Perceived Effect scale (GPE) and the Numeric Pain Rating Scale (NPRS), and by the Receiver Operating Characteristic (ROC) Curve test based on the area under the curve (AUC).

Results

The OSTRC-QHP has been translated and cross-culturally adapted successfully. The Cronbach's alpha was 0.93 (95% CI: 0.92, 0.94). Intrarater reliability (ICC_2,1) of 0.96 (95% CI: 0.94, 0.98) was classified as excellent. ES estimation showed large effects (1.14 to 1.39). OSTRC-BR correlation was moderate (0.58 to 0.72) with the GPE and substantial (0.84 to 0.89) with the NPRS. The AUC values were above 0.70 when analysing all types of health problems.

Conclusions

The OSTRC-BR presented adequate measurement properties. The OSTRC-BR is a valid, reliable, responsive, and, therefore, an adequate tool for monitoring Brazilian athletes from different sports during training and competitions.
