dc.description.abstractObjective: To evaluate the psychometric properties of the Brazilian version of health-related quality-of-life questionnaires of children with food allergy and their parents. Methods: The translation and cultural adaptation processes were previously performed, according to the method proposed by the World Health Organization. After this stage, the questionnaires were applied to 201 parents of children under 6 years of age with food allergy. The assessment of the psychometric properties included: evaluation of the internal consistency by Cronbach's alpha coefficient; of the reproducibility by the intraclass correlation coefficient between test and retest; and of the construct, using Spearman's correlation coefficient, comparing the obtained scores with those of generic questionnaires that evaluate health-related quality of life. Results: The means of the obtained scores were 2.44 and 3.35, for the children and their parents, respectively. Cronbach's alpha coefficients were 0.85 and 0.91, respectively, which showed good internal consistency of the tools. The intraclass correlation coefficients between test and retest were 0.87 and 0.84 for children and their parents, respectively, showing good reproducibility for both questionnaires. The correlation between the specific and the generic questionnaires was significant (−0.27 for the children, −0.64 for their parents, p<0.05). Conclusions: The specific questionnaires to evaluate the health-related quality of life of children with food allergy and of their parents were satisfactorily validated to be used in Brazil.en
dc.description.abstractObjetivo: Avaliar as propriedades psicométricas da versão brasileira dos questionários de qualidade de vida relacionada à saúde de crianças com alergia alimentar e de seus pais. Método: Os processos de tradução e adaptação cultural foram realizados previamente, de acordo com o método proposto pela Organização Mundial da Saúde. Após essa etapa, os questionários foram aplicados a 201 pais de crianças menores de 6 anos de idade com alergia alimentar. A avaliação das propriedades psicométricas incluiu: avaliação da consistência interna, pelo coeficiente alfa de Cronbach; da reprodutibilidade, pelo coeficiente de correlação intraclasse entre teste e reteste; e do constructo, empregando-se o coeficiente de Correlação de Spearman, comparando os escores obtidos com os de questionários genéricos que avaliam a qualidade de vida relacionada à saúde. Resultados: As médias dos escores obtidos foram 2,44 e 3,35, para as crianças e seus pais, respectivamente. Os Coeficientes alfa de Cronbach foram 0,85 e 0,91, respectivamente, o que demonstrou boa consistência interna dos instrumentos. Os coeficientes de correlação intraclasse entre os testes e os retestes foram 0,87 e 0,84, para crianças e seus pais, respectivamente, demonstrando boa reprodutibilidade para ambos os questionários. A correlação entre os questionários específicos e genéricos foi significante (−0,27 para as crianças; −0,64 para os pais; p < 0,05). Conclusões: Os questionários específicos para avaliar a qualidade de vida relacionada à saúde de crianças com alergia alimentar e de seus pais foram satisfatoriamente validados para uso no Brasil.pt
