ABSTRACT
O objetivo deste estudo foi construir um instrumento que avalia a qualidade de vida no trabalho de forma global, seguindo os moldes dos instrumentos de avaliação da qualidade de vida da Organização Mundial da Saúde (WHOQOL) e alicerçado nos modelos teóricos clássicos de qualidade de vida no trabalho, com direcionamento para a sociedade contemporânea brasileira. Metodologia A validação de conteúdo foi realizada através da análise por pesquisadores da área da qualidade de vida no trabalho, enquanto a verificação da consistência interna ocorreu por meio da utilização do coeficiente alfa de Cronbach, em uma aplicação a 143 indivíduos. Resultados A versão final do instrumento é constituída de 47 questões, sendo cinco para conhecimento da amostra e 42 seccionadas em cinco esferas que contemplam as dimensões da qualidade de vida no trabalho. O alfa de Cronbach obtido a partir da aplicação do instrumento foi de 0,8568. Para o cálculo dos resultados do instrumento fora desenvolvida a sintaxe SPSS e uma ferramenta no software Microsoft Excel que realiza os cálculos forma automatizada após a tabulação dos dados. Conclusão Conclui-se que o objetivo de validar um instrumento global de avaliação da qualidade de vida no trabalho validado a partir da cultura hodierna brasileira, com características psicométricas satisfatórias foi atingido, podendo este ser aplicado sem a obrigatoriedade de utilização do software SPSS...
The objective of this study was to build an instrument that evaluates quality of working life (QW:) in a comprehensive way that is in line with the WHOQOL instruments and is based on QWL's classic theoretical models, directed toward contemporary Brazilian society. Methods The content validation was performed through analysis by researchers in the area of QWL, and the verification of internal consistency was performed with Cronbach's alpha. The instrument was administered to 143 individuals. Results The final version of the instrument consists of 47 questions, with five for sampling knowledge and the remaining 42 divided into five spheres that take into account the dimensions of QWL.. Cronbach's alpha obtained from the administration of the instrument was 0.8568. A SPSS syntax and a tool in Microsoft Excel that performs the automated calculation after data tabulation was developed to calculate the results. Conclusions We conclude that the goal of validating a comprehensive instrument with satisfactory psychometrical characteristics for the evaluation of QWL based on contemporary Brazilian culture was reached. This tool may be used without a need for SPSS utilization...

Detection of Coxiella burnetii, the etiologic agent of Q fever, is important for diagnosis of Q fever. PCR-based methods have been widely used for the detection mostly because isolation of C. bumetii is time-consuming. Recent reports showed that PCR-positive rates of Q fever infection widely differed. We have evaluated the PCR and nested PCR assays currently used in Japan. The nested PCR assay detected as few as 6 microorganisms and was 10 times more sensitive than the regular PCR assay. The nested PCR assay did not show any non-specific bands with 12 other bacteria, whereas the PCR assay showed some extra bands for 5 of the 12 bacteria. These results suggest that the nested PCR is more sensitive and specific than the PCR in the detection of C. burnetii. However, nested PCR generally has a risk of cross-contamination during preparation of the 2nd PCR. Using blood specimens serially collected from an acute Q fever patient, the PCR and the nested PCR assays gave very similar results, suggesting that sensitivity of the PCR assay is at an achieved level of the detection for clinical specimens although the nested PCR assay is more sensitive. It is recommended that both the PCR and nested PCR assays should be performed for the detection of C. burnetii to obtain reliable results.
