A Development and Validation Process for a Disease-Specific Quality of Life Instrument

Abstract: A heartburn-specific quality of life instrument was developed using an approach which involves several steps: generating and selecting items, pretesting, reproducibility testing, and validity testing. These last two steps were performed in a randomized, double blind, placebo-controlled, six-week clinical trial evaluating ranitidine 150 mg twice daily on the clinical, economic, and humanistic outcomes of patients witqgastroesophageal reflux disease. Reliability, content validity, and construct validity were ass… Show more

“…The internal consistency of the ACT, in terms of Cronbach's alpha coefficients, was for the most part consistent with usual practice for measures intended to be used at the level of the group , or in our case, the resident care unit [46,52]. Only two concepts had unacceptably low reliabilities: organizational slack-space and formal interactions.…”

“…Levantamento recente do grau de escolaridade dos pacientes atendidos no Setor de Ambulatório do Hospital São Paulo (UNIFESP) revelou ser a distribuição do nível de escolaridade semelhante à da população brasileira * . Tendo em vista a heterogeneidade desses questionários e a inexistência de instrumento único que conciliasse avaliação ampla da qualidade de vida com a pesquisa das manifestações típicas e atípicas da DRGE, optou-se por traduzir simultaneamente três destes questionários GSAS (31) , GERD-HRQL (43,44) e HBQOL (47) , de forma a disponibilizar em nosso meio três opções distintas, cada qual com as suas peculiaridades, de forma a dar maleabilidade a pesquisadores e médicos em geral, na seleção o questionário mais apropriado para analisar qualidade de vida na DRGE de acordo com os objetivos de seu trabalho.…”

“…O método de aplicação, originalmente testado para os instrumentos selecionados, é o de auto-aplicação, não havendo referência ao método de entrevista com observador treinado ou a outros métodos de aplicação (43,44,47) . Tendo em vista as características sócio-culturais da nossa população (19) , mormente aos elevados índices de analfabetismo, os dois instrumentos estudados, assim como os questionários ESDRGE e SF-36, quando apropriados, foram aplicados através de entrevista realizada pela pesquisadora principal e por dois observadores II treinados para atuar na UNIFESP e FAMERP.…”
