ABSTRACT
OBJECTIVE: to translate, adapt and test the psychometric properties of the Brazilian Nurse-Work Instability Scale. METHOD: this was a methodological study following the translation steps: synthesis, back-translation, specialist´s committee, semantics analysis, pretest, and psychometric tests. The committee was composed of 5 specialists. For the semantics analysis, 18 nursing workers evaluated the instrument and 30 pretested it. For the psychometric tests, the sample size was 214 nursing workers. The internal construct validity was analyzed by the Rasch model. Reliability was assessed using internal consistency, and concurrent validity with Pearson's correlation between the Nurse-Work Instability Scale, and the Work Ability Index, Job Stress Scale. RESULTS: a Nurse-Work Instability Scale in Brazilian Portuguese with 20 items showed an adequate reliability (0.831), stability (p <0.0001), and an expected correlation with Work Ability Index (r = -0.526; P<0.0001) and Job Stress Scale (r = 0.352; p <0.0001). CONCLUSION: the instrument is appropriated to detect work instability in Brazilian nursing workers with musculoskeletal disorders. Its application is fundamental to avoid long-term withdrawal from work by early identification of the work instability. Furthermore, the scale can assist the development of actions and strategies to prevent the abandonment of the profession of nursing workers affected by musculoskeletal disorders.

Objetivo traduzir, adaptar e testar as propriedades psicométricas da Nurse-Work Instability Scale (Escala de Instabilidade no Trabalho de Enfermagem) em português do Brasil. Método trata-se de um estudo metodológico seguindo os passos de tradução: síntese, retrotradução, comitê de especialistas, análise semântica, pré-teste e testes psicométricos. O comitê foi composto por 5 especialistas. Para a análise semântica, 18 profissionais de enfermagem avaliaram o instrumento e 30 fizeram o pré-teste. Para os testes psicométricos, o tamanho da amostra foi de 214 profissionais de enfermagem. A validade interna do construto foi analisada pelo modelo de Rasch. A confiabilidade foi avaliada usando consistência interna e validade concorrente com a correlação de Pearson entre a Nurse-Work Instability Scale, o Work Ability Index (Índice de Capacidade para o Trabalho) e a Job Stress Scale (Escala de Estresse no Trabalho). Resultados a Nurse-Work Instability Scale com 20 itens em português brasileiro apresentou confiabilidade (0,831), estabilidade (p <0,0001) e correlação esperada adequadas com o Work Ability Index (r = -0,526; P 0,0001) e a Job Stress Scale (r = 0,352; p 0,0001). Conclusão o instrumento é apropriado para detectar a instabilidade do trabalho em profissionais de enfermagem brasileiros com distúrbios osteomusculares. Sua aplicação é fundamental para evitar o afastamento do trabalho a longo prazo pela identificação precoce da instabilidade do trabalho. Além disso, a escala pode auxiliar no desenvolvimento de ações e estratégias para prevenir que profissionais de enfermagem acometidos por distúrbios osteomusculares abandonem a profissão.

Objetivo traducir, adaptar y probar las propiedades psicométricas del Escala Brasileña de Inestabilidad en el Trabajo de Enfermería. Método ha sido un estudio metodológico en la secuencia de las etapas de la traducción: la síntesis, la retrotraducción, el comité de expertos, el análisis semántico, la prueba previa y las pruebas psicométricas. El comité ha sido conformado por 5 expertos. Para el análisis semántico, 18 trabajadores han evaluado el instrumento y 30 han sido probados previamente. Para las pruebas psicométricas, el tamaño del muestreo ha sido de 214 trabajadores de enfermería. La validez del constructo interno ha sido analizada por el modelo de Rasch. La confiabilidad ha sido evaluada por medio de la consistencia interna, y la validez competente con la correlación de Pearson entre la Escala de Inestabilidad en el Trabajo de Enfermería, y el Índice de Capacidad de Trabajo, Escala de Estrés en el Trabajo. Resultados una Escala de Inestabilidad en el Trabajo de Enfermería Portugués con 20 ítems ha mostrado una confiabilidad adecuada (0.831), estabilidad (p <0.0001), y una correlación que ha sido esperada con el Índice de Capacidad de Trabajo (r = -0.526; P<0.0001) y la Escala de Estrés en el Trabajo (r = 0.352; p <0.0001). Conclusión el instrumento es apropiado para detectar la instabilidad del trabajo en trabajadores Brasileños con disturbios musculo esqueléticos. Su aplicación es fundamental para evitar el abandono de largo plazo del trabajo por la identificación temprana de la instabilidad del trabajo. Además de eso, la escala puede ayudar en el desarrollo de acciones y estrategias para prevenir el abandono de la profesión de trabajadores de enfermería que han sido afectados por el disturbio musculo esquelético.

This article aims to present the main characteristics of Rasch analysis in the context of patient reported outcomes in Psychiatry. We present an overview of the main features of the Rasch analysis, using as an example the latent variable of depressive symptoms, with illustrations using the Beck Depression Inventory. We will show that with fitting data to the Rasch model, we can confirm the structural validity of the scale, including key attributes such as invariance, local dependency and unidimensionality. We also illustrate how the approach can inform on the meaning of the numbers attributed to scales, the amount of the latent traits that such numbers represent, and the consequent adequacy of statistical operations used to analyse them. We would argue that fitting data to the Rasch model has become the measurement standard for patient reported outcomes in general and, as a consequence will facilitate a quality improvement of outcome instruments in psychiatry. Recent advances in measurement technologies built upon the calibration of items derived from Rasch analysis in the form of computerized adaptive tests (CAT) open up further opportunities for reducing the burden of testing, and/or expanding the range of information that can be collected during a single session.
