Abstract
Objective: The present study aimed to adapt and validate the self-report tool named Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians (MPIIQM-Br) into the Brazilian Portuguese language for professional orchestra musicians.
Methods: The cross-cultural adaptation process was divided into nine steps. Five experts evaluated the equivalences among versions and the content validity ratio (CVR). The structural validity was verified by exploratory factor analysis (EFA). Construct validity was checked by convergent/divergent validity by comparing the results obtained by the MPIIQM-Br, the Brief Pain Inventory (BPI), and Disabilities of the Arm, Shoulder, and Hand Questionnaire-optional module (DASH-PAM), and the Kenny Music Performance Anxiety Inventory (K-MPAI). Finally, reliability was tested with internal consistency and test-retest reliability.
Results: In total, 273 professional orchestra musicians (137 males) participated. The researchers found good equivalence among versions, and the CVR reached 0.99. EFA (n=212) showed that the MPIIQM-Br had two factors that explained 70% of the total variance. The convergent validity confirmed a strong positive correlation (r>0.7) and the divergent validity established a low correlation (r<0.4). Both internal consistency (Cronbach's a=0.90) and temporal stability (intraclass correlation coefficient=0.84) obtained high values.
Discussion: The psychometric evaluation showed a two-dimensional structure, internal consistency, and temporal stability similar to the original tool and the German and Polish versions of the MPIIQM. However, the pain prevalence rates among Brazilian musicians were higher. Extreme informality and the growing demotivation may explain these findings.
Conclusions: The MPIIQM-Br is a transcultural equivalent, reliable, and valid tool for the measurement and evaluation of pain and pain interference among professional orchestra musicians.
