BACKGROUND: The aim of the study was the cross-cultural adaptation and validation of the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians.
MATERIAL AND METHODS: The process consisted of the following stages: forward translation, backward translation, analysis by committee of experts, pretest of Polish-language version of questionnaire, and cross-cultural validation: psychometric evaluation. In the last step, a convenience sample of 31 professional orchestra musicians (professional experience 16.7±9.5 years) was used to validate the new tool. The primary study outcome measurements were construct validity and internal consistency as measured by exploratory factor analysis (EFA) and Cronbach’s alpha, respectively.
RESULTS: A final Polish version of the questionnaire was developed. Using EFA, the 2-factor structure (pain intensity and pain interference) was obtained, taking into account all 9 items, explaining about 76% of the total variance. The pain interference and pain intensity factors were characterized by high internal consistency (Cronbach’s alpha 0.923 and 0.784, respectively). The lifetime prevalence of playing-related musculoskeletal disorders was 87%.
CONCLUSIONS: Translation and a cross-cultural adaptation of the Polish version of the questionnaire was successfully completed. The results obtained show a correctly carried-out validation process, but further testing of the tool is suggested. The Polish-language version of the validated tool can be used in scientific and clinical practice. The next step would be to estimate cutoff values for severity of health status in orchestra musicians.
