RESUMO
BACKGROUND: The aim of this study is to translate, culturally adapt, and validate a Spanish version of the Nordic Musculoskeletal Questionnaire for a sample of nursing assistant aides. METHODS: The questionnaire was translated and culturally adapted. Next, it was included in a battery of tests that was completed by 526 nursing assistants working in residential care homes in the Principality of Asturias (Spain). To assess its validity, the Exploratory Factor Analysis and the Confirmatory Factor Analysis were used. The internal consistency was estimated with McDonald's Omega coefficient (?), complemented by the test-retest reliability analysis through the intraclass correlation coefficient. The validity of the criteria was established by the correlation between total score on the test and quality of life measures, job insecurity and psychological demand, and social support at work. RESULTS: The Exploratory Factor Analysis and Confirmatory Factor Analysis adjustment indices confirmed it is a unidimensional test. The internal consistency values indicated very high reliability (? = 0.81). Similarly, the intraclass correlation coefficient showed statistically significant values and an excellent correlation coefficient (r = 0.95). The validity of the criteria showed a statistically significant correlation with all the constructs studied, particularly with quality of life. CONCLUSIONS: This Spanish version of the Nordic Musculoskeletal Questionnaire has good psychometric qualities for a population of nursing aides and therefore may be a valid and reliable tool for assessing musculoskeletal disorders.

Fundamento. El objetivo de este trabajo es traducir, adaptar culturalmente y validar una versión española del Nordic Musculoskeletal Questionnaire (NMQ) en una muestra de personal auxiliar de enfermería. Metodología. Se realizó la traducción y adaptación cultural del cuestionario y se incluyó dentro de una batería de escalas, cumplimentada por 526 auxiliares de enfermería de centros residenciales para personas mayores del Principado de Asturias. Se analizó la validación de la escala a través de la sucesión del análisis factorial exploratorio (AFE) y el análisis factorial confirmatorio (AFC). La consistencia interna se estimó con el coeficiente ordinal ω de McDonald, complementándose con el análisis de fiabilidad test-retest por medio del coeficiente de correlación intraclase (ICC). La validez de criterio se estimó a través de la correlación de la puntuación total de la prueba con las medidas de calidad de vida, incertidumbre laboral, demanda psicológica y apoyo social en el trabajo. Resultados. Los índices de ajuste de AFE y AFC mostraron que se trata de una prueba unidimensional. Los valores de consistencia interna señalaron una fiabilidad muy alta (ω= 0,81) y el ICC fue excelente (r= 0,95). La validez de criterio mostró una correlación estadísticamente significativa con todos los constructos estudiados, especialmente con la calidad de vida. Conclusiones. La presente versión española del NMQ presenta unas buenas cualidades psicométricas en la población de personal auxiliar de enfermería por lo que podría ser una herramienta válida y fiable en la evaluación de los trastornos musculoesqueléticos.

Work-related musculoskeletal disorders are some of the most prevalent diseases in the world. They have a multifactorial aetiology encompassing ergonomic and psychosocial risk factors. The aim of this study is to analyse the way job insecurity and physical workload are linked to musculoskeletal disorders, as well as the mediating role other psychosocial work risks can have on this potential relationship. A parallel mediation path regression analysis was designed using a sample of 457 nursing aides. The influence job insecurity and physical workload has on the onset of musculoskeletal symptoms together with the variables which mediate this relationship were examined. The results prove that both independent variables explain the onset of musculoskeletal symptoms in these professionals. The influence exerted by job insecurity is mediated by the social support received at work and the demands of the job. However, when analysing the physical workload, the social support received at work is not relevant as a mediator in this relationship. Job insecurity and physical workload are significant variables on the occurrence of musculoskeletal symptoms. The data obtained supports the need to focus on physical and psychosocial factors in order to prevent these disorders.
