| Abstract | |
The health care workers are a risk group for developing musculoskeletal disorders, especially nurses. The objectives of this research were to develop a questionnaire that evaluates the perception of nursing workers to job factors that may contribute to musculoskeletal symptoms, to evaluate its psychometric properties, and to analyze the instruments' results. The development of survey methodologies followed standards of construction and adaptation tools. Literature reviews, identification of measurement instruments and interviews with a sample of the survey's target population were performed. The development stages of domains, items and the instrument as a whole had its content assessed by two expert committees. After the content validity, a pre-test of the questionnaire was performed. Data were obtained through interviews with 370 nursing workers of two hospitals. Data collection was carried out in order to evaluate the psychometric qualities of the final version: "ErgoEnf - Questionnaire to evaluate ergonomic risk in nursing", which was composed by 32 items distributed in four domains. The construct validity was analyzed by the factorial analysis, the technique of the known groups (nursing workers and administrative workers) and by the convergent validity, comparing the results of the instrument with the answers to the Numeric pain scale the SF- 36, and the Work Role Functioning Questionnaire (WRFQ). Reliability was assessed through internal consistency and stability (test-retest). Different quantitative analysis were performed, i.e., descriptive analysis, technique of confirmatory factor analysis, the Mann- Whitney test to compare known groups, the Spearman correlation test to correlate the new questionnaire scores with other measurement instruments, Cronbach's alpha to study the internal consistency, and the Intra-class Correlation Coefficient (ICC) to investigate the stability. The confirmatory factor analysis indicated that the questionnaire indices are all tweaking satisfactory, confirming the pre-defined structure of the questionnaire. There was also a significant difference (p <0.01) between the responses of nursing staff and administrative area workers in all domains of ErgoEnf. The correlations between the new questionnaire and Numeric pain scale, SF-36 and WRFQ were all significant (p <0.01) and most of them of moderate magnitude. Cronbach's alpha calculated to verify the instrument's internal consistency ranged from 0.89 to 0.91. ICC values ranging from 0.64 to 0.76 indicated the stability of the questionnaire. The mean values of the ErgoEnf domains showed that nursing workers perceived biomechanical factors exerting a moderate influence to the development of musculoskeletal symptoms, whereas environmental, organizational and psychosocial factors showed a minimal influence related to the symptoms. Therefore, the process of development and validation of the "ErgoEnf - Questionnaire to evaluate ergonomic risk in nursing" was completed with results that indicate good psychometric properties for use in ergonomic studies with nursing workers (AU) | |
