Resumo

CONTEXTO E OBJETIVO: O Beliefs about Medicines Questionnaire (BMQ-Específico) tem se mostrado útil na mensuração sobre as crenças dos pacientes e associando-os à não adesão ao tratamento em vários grupos de doença. O objetivo foi realizar a adaptação transcultural do BMQ-Específico em Português para a população geral de usuários de medicamentos. TIPO DE ESTUDO E LOCAL: Estudo transversal conduzido com usuários de hospitais públicos e clínicas ambulatoriais em Guarda e Covilhã, Portugal. MÉTODOS: O BMQ-Específico foi traduzido utilizando-se recomendações internacionais para realizar a adaptação transcultural e foi administrado a 300 pacientes. Uma primeira análise de componentes principais (ACP) com critério de extração eigenvalue > 1.0 foi realizada, seguida de uma segunda ACP com restrição para dois componentes. A confiabilidade foi avaliada calculando-se o coeficiente alfa de Cronbach. RESULTADOS: Os escores médios obtidos para as subescalas de Necessidade e Preocupação do BMQ-específico em Português foram de 19,9 (desvio padrão, DP = 2,8; intervalo 10 a 25) e 1,7 (DP = 3,9; intervalo 6 a 30), respectivamente. A primeira ACP produziu estrutura instável de três componentes para o BMQ-específico em português. A solução final de ACP produziu estrutura de dois componentes idênticos à versão original em inglês (subescala de Necessidade de 5 itens e subescala de Preocupação de 6 itens), explicando 44% da variância. Alfa de Cronbach para o BMQ-Específico em Português completo foi de 0,70, sendo 0,76 e 0,67 para as subescalas de Necessidade e Preocupação, respectivamente. CONCLUSÃO: A versão adaptada do questionário BMQ-Específico em português para ser utilizada na população em geral dos usuários de medicamentos foi obtida, apresentando boa consistência interna e estrutura do componente idêntica à versão original em inglês.
