Abstract
OBJETIVO: desenvolvimento da versão em português brasileiro do Endometriosis Health Profile Questionnaire (EHP-30), adaptação transcultural ao Brasil e avaliação das medidas psicométricas do EHP-30 Português em amostra brasileira. MÉTODOS: o instrumento original em inglês foi vertido para o português, seguindo diretrizes internacionais, passando por todas as etapas de tradução, retrotradução e comparação das versões para adaptação transcultural, validade de face e de conteúdo. O EHP-30 Português foi aplicado a uma amostra de 54 pacientes com diagnóstico de endometriose para análise de consistência interna, usando o alfa de Cronbach. A fidedignidade teste-reteste foi avaliada pelo coeficiente de correlação intraclasse (ICC). Para a avaliação de validade de construto convergente foi testada correlação entre o EHP-30 Português, WHOQOL-Bref e o Inventário de Depressão de Beck (BDI). RESULTADOS: a avaliação da consistência interna apresentou valores de α=0,8 a 0,9, sugerindo homogeneidade entre as questões. A fidedignidade teste-reteste apresentou ICC de 0,8 a 0,9, demonstrando estabilidade do instrumento. Na validação de construto, demonstraram-se fortes correlações da escala de auto-imagem do EHP-30 com os domínios físico (-0,6) e psicológico (-0,6) do WHOQOL-Bref e da escala de suporte social com o BDI (0,5), evidenciando-se, assim, boa correlação com outros instrumentos de avaliação de qualidade de vida. CONCLUSÕES: o EHP-30 Português mostrou ser um instrumento de fácil e rápida aplicação e bem aceito pelas pacientes, apresentando bom desempenho psicométrico, com medidas de fidedignidade adequadas (consistência interna e fidedignidade teste-reteste) e validade de construto. Estes resultados demonstram que o EHP-30 Português é um instrumento adequado para avaliação de qualidade de vida em mulheres brasileiras com endometriose em ambiente clínico e de pesquisa.
PURPOSE: the objective of the present study was the development of the Brazilian Portuguese version of Endometriosis Health Profile Questionnaire (EHP-30), the cross-cultural adaptation to Brazil and the evaluation of EHP-30 Portuguese psychometric measures in a Brazilian sample. METHODS: the original instrument in English was translated into Portuguese following international guidelines, going through all stages of translation, back-translation and comparison of the versions for cross-cultural adaptation, face and content validity. A sample of 54 patients with endometriosis was used for internal consistency analyses using the Cronbach alpha. Test-retest reliability was evaluated through the intraclass correlation coefficient (ICC). In order to evaluate the convergent construct validity, the correlation between EHP-30 Portuguese and WHOQOL-Bref and Beck Depression Inventory (BDI) was tested. RESULTS: internal consistency presented alpha values of 0.8 to 0.9 suggesting homogeneity between questions. The test-retest reliability presented ICC of 0.8 to 0.9 showing instrument stability. In the construct validation, strong correlations were demonstrated of the EHP-30 Portuguese self-image scale with physical (-0.6) and psychological domains (-0.6) of WHOQOL-Bref, and EHP-30 Portuguese social support scale with BDI (0.5), confirming good correlation with other quality of life evaluation instruments. CONCLUSIONS: the EHP-30 Portuguese was found to be an easy, quickly applied instrument, and well-accepted by the patients. It presented good psychometric properties with appropriate reliability measures (internal consistency and test-retest reliability) and construct validity. These results show that EHP-30 Portuguese is an adequate instrument for quality of life evaluation in Brazilian women with endometriosis, both in clinical and research setting.
