Dutch musculoskeletal questionnaire: description and basic qualities

The article describes the Dutch Musculoskeletal Questionnaire (DMQ) for the analysis of musculoskeletal workload and associated potential hazardous working conditions as well as musculoskeletal symptoms in worker populations. Its qualities are explored using a database of 1,575 workers in various occupations who completed the questionnaire. The DMQ-questions can be categorized into 7 indices (force, dynamic and static load, repetitive load, climatic factors, vibration and ergonomic environmental factors). Together with 4 separate questions on standing, sitting, walking and uncomfortable postures, the indices constitute a brief overview of the findings on musculoskeletal workload and related working conditions. Homogeneity of the indices is satisfactory. The divergent validity of the indices is fair when compared with an index of psychosocial working conditions and discomfort during exposure to physical loads. Furthermore it appears that most indices and factors show significant associations with low back and/or neck-shoulder symptoms. The DMQ can be used as a simple and quick check to identify worker groups that need thorough ergonomic control. ©Medlin
