| Abstract | |
Musculoskeletal disorders represent a serious problem in public health, resulting in absenteeism, loss of work and disabilities. Questionnaires have been considered useful to identify musculoskeletal symptoms and to investigate correlated factors in workplace. The study objectives were to translate and adapt the Work Role Functioning Questionnaire into the Brazilian Portuguese language and evaluate its reliability in patients suffering from musculoskeletal disorders. The cross-cultural adaptation was performed according to the internationally recommended methodology, using the following guidelines: translation, back-translation, revision by a committee and pretest. The pretest was carried out with 30 patients suffering from musculoskeletal disorders. Psychometric properties were evaluated by administering the questionnaire to 105 subjects with musculoskeletal disorders and receiving physical therapy treatment. The reliability was estimated through stability and homogeneity assessment. The construct validity was tested comparing the 105 subjects suffering from musculoskeletal disorders to 105 healthy workers. The results indicated good content validity and internal consistency (Cronbach alpha= 0,95). Cronbach alpha for each scale was > 0,85, except for the social demand scale. The Intraclass Correlation Coefficient for the test-retest reliability was satisfactory for mental demands (ICC= 0,68) and excellent for the others (0,82 ¿ 0,91). In relation to the construct validity, the mean score obtained for each scale was lower for physical, work scheduling, and output demands in the subjects with musculoskeletal disorders. There was a significant difference (p<0,001) between the groups in comparison to work scheduling, physical and output demands. The data showed that the cross-cultural adaptation process was successful and the adapted instrument demonstrated psychometric properties making it reliable to use in the Brazilian culture.
