Resumo:
Resumo: Objetivo: Avaliar as propriedades psicométricas do 12-ITEM HEALTH SURVEY (SF-12).Métodos: Foram utilizados dados de um inquérido epidemiológico de saúde bucal realizado em 2008/2009 no município de Montes Claros, MG, constituído de 2157 indivíduos de ambos os sexos. A estrutura relacional do SF-12 foi avaliada pela Análise Fatorial Exploratória (AFE), a confiabilidade foi avaliada através do coeficiente alfa de Cronbach, o coeficiente de correlação de Pearson foi adotado para avaliar as correlações entre cada item do questionário e seus escores finais. A validade de constructo foi investigada através da comparação dos níveis dos escores dos componentes físico (PCS) e mental (MCS) do SF-12 entre subgrupos populacionais, utilizando-se os testes Mann-Whitney e Kruskal-Wallis. Resultados: Os domínios PCS e MCS apresentaram médias (desvio-padrão), respectivamente, iguais a 49,6(9,0) e 51,9(8,6). O coeficiente alfa de Cronbach (α= 0.836) apresentou alto grau de confiabilidade. A estrutura relacional foi explicada por dois fatores latentes, que explicaram 58,36% da variância total.Conclusão: As propriedades psicométricas do SF-12 sugerem que esse é um instrumento sensível para a avaliação de diferentes níveis de QV, é confiável, tem uma consistência interna satisfatória e possui uma rápida e fácil aplicação.

Abstract:
Abstract: Objective: To assess the psychometric properties of the SURVEY (SF-12). Methods: Data from an oral health epidemiological survey were used, conducted in 2008/2009 in the municipality of Montes Claros, MG, consisting of 2157 individuals of from both male and female sexes. The relational structure of the SF-12 was assessed through the Factor Exploratory Analysis (FEA), the reliability was assessed through the Cronbach’s alpha coefficient, Pearson’s correlation coefficient was adopted in order to assess the correlations between each questionnaire item and their final scores. The validity of the construct was investigated by comparing the physical (PCS) and mental (MCS) component scores level of the SF-12 among the population subgroups, using Mann-Whitney and Kruskal-Wallis tests. Results: The PCS and MCS domains presented means (standard deviation), respectively, equal to 49.6(9.0) and 51.9(8.6). The Cronbach’s alpha coefficient (α= 0.836) presented a high degree of reliability. The relational structure was explained by two latent factors, which explained the 58.36% of the total variance. Conclusion: The psychometric properties of the SF-12 suggest that this is a sensitive instrument to assess the different QL levels, is reliable, has satisfactory internal consistence and is fast and easy to use.
