ObjectiveThe study aimed to translate, culturally adapt, and test the psychometric properties of the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians (MPIIQM) in an Italian population of professional and amateur musicians.MethodsThe translation and cultural adaptation process followed international guidelines, while the reliability and validity of the questionnaire were assessed against the COSMIN checklist. The internal consistency was calculated using Cronbach's alpha (a) coefficient. Construct validity was analyzed using exploratory factor analysis (EFA) with principal axis factoring (PAF) extraction. The sample adequacy and data suitability were assessed through the Kaiser-Meyer-Olkin (KMO) and Bartlett's sphericity tests, respectively. Concurrent validity was analyzed by assessing Pearson's correlation coefficient with the Italian version of the Musculoskeletal Health Questionnaire (MSK-HQ-I). Finally, the cross-cultural validity was investigated by analyzing score differences between amateur and professional musicians, and differences based on musical practice habits.ResultsThe tool was administered to 311 subjects recruited from across Italy. The MPIIQM-IT was found to have high levels of internal consistency for the entire tool and each of the two subscales (Cronbach's a = 0.875, 0.877, and 0.845, respectively). The recruited sample was found to be adequate (KMO = 0.810) and the data suitable (C2 = 341.040, p < 0.001) for factor analysis, which produced 9 items contained in two main factors. Pearson's correlation coefficients showed a positive, statistically significant correlation between the MSK-HQ-I and the two subscales of the MPIIQM-IT with p < 0.01. Analysis of Student's t-test for independent samples and the ANOVA test for continuous variables showed statistically significant differences between male and female, professional and non-professional musicians, and conservatory and non-conservatory students.ConclusionsThe MPIIQM-IT is a valid and reliable tool, useful for investigating the presence of pain and playing-related musculoskeletal disorders (PRMDs) in both professional and non-professional musicians.
