Brazilian Version of the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians (MPIIQM-Br): Cross-Cultural Adaptation and Psychometric Properties

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.

Questionnaire for Orchestra Musicians: Validation of the Online Version of the Musculoskeletal Pain Intensity and Interference Questionnaire for Polish Musicians (MPIIQM-P)

“…The variable “Most severe pain” showed a strong correlation with each factor, although the highest one of 0.61 was demonstrated for pain interference, making it the variable part of that factor. The result is in opposition to previous studies in which the variable “Most severe pain” was consistent within the group with the pain intensity factor [ 8 , 9 , 10 , 11 ]. The correlations for other variables were consistent with previous validations conducted in other countries, excluding the validation conducted by Cygańska et al [ 10 ], in which the variable “Pain right now” explained the pain interference factor.…”

“…The factor loadings of the variables after EFA ranged from 0.61 to 0.87. In other studies in this field, the loadings ranged from 0.69 to 0.97 in the study by Berque et al [ 4 ], from 0.59 to 0.94 in the validation conducted by Möller et al [ 8 ], from 0.67 to 0.90 in a study by Zão et al [ 11 ], from 0.57 to 0.91 in validation by Kochem et al [ 9 ], from 0.68 to 0.96 in the validation of the MPIIQM questionnaire conducted by Cygańska et al [ 10 ], and from 0.59 to 0.94 in a validation of the French-language version of the questionnaire by Roos et al [ 13 ].…”

“…The group of respondents was 182 people, the second largest group in the research in this field. Only researchers conducting validation of the MPIIQM questionnaire in Brazil collected a larger group of 273 people [ 9 ]. During a validation study of the MPIIQM questionnaire, the response rate ranged from 33.8% [ 8 ] to 73.6% [ 11 ].…”

“…The MPIIQM questionnaire is a complete tool with specific psychometric properties, validated based on COSMIN standards [ 6 , 7 ]. Translation and cultural adaptation of the MPIIQM questionnaire has already been performed in German [ 8 ], Brazilian Portuguese [ 9 ], Polish [ 10 ], Portuguese [ 11 ], Turkish [ 12 ] and French [ 13 ].…”

Music Psychological Meta-Analysis and Real-Time Measurement Algorithm Based on Nonlinear Dynamic Incremental Internal Model Algorithm

“…Considering that the object may drift under complex working conditions, it is necessary to design the controller to realize the optimal control of the system within a certain allowable threshold of model adaptation [8]. For this reason, a set of adaptive-internal model control scheme is designed, that is, the model parameters gradually approach the parameters of the controlled object, and the updated model parameter values are used to correct the IMC parameters online, thereby improving the system's ability to resist disturbance and model adaptation [9]. rough mathematical transformation, the IMC controller can be equivalent to a feedback controller, and further transformed into a PID controller that is generally applicable in industrial fields.…”
