RESUMEN
ABSTRACT The objective of this study was to obtain reliability and validity evidence for the questionnaire of illness representation, the impact of epilepsy, and stigma (QIRIS) for use with adolescents and adults in Brazil. QIRIS consists of 14 questions grouped in three domains (attribution of meaning, impact of disease, and stigma) and was applied to 57 adults with epilepsy. QIRIS internal consistency was satisfactory (Cronbach’s α = 0. 866). Significant and strong correlation was found between issues belonging to the same domain, as expected. Three domains have highly significant and positive correlations with the instrument’s total score, indicating evidence of content validity. We conclude that QIRIS has psychometric properties and can facilitate a systematic evaluation of the patient’s representation according to a biopsychosocial approach that may contribute to clinical practice based on scientific evidence.
RESUMO Este estudo buscou evidências de confiabilidade e validade para o questionário de representação da doença, impacto da epilepsia e estigma (QIRIS), para uso em adolescentes e adultos no Brasil. O QIRIS consiste de 14 questões agrupadas em 3 domínios (atribuição de significados, impacto da doença e estigma) e foi aplicado em 57 adultos com epilepsia. A consistência interna do QIRIS foi satisfatória (α de Cronbach = 0,866). Foi encontrada forte e significante correlação entre as questões com o mesmo domínio.Os três domínios têm correlações altamente significativas e positivas com a pontuação total do instrumento, indicando evidências de validade de conteúdo. Concluímos que o QIRIS tem propriedades psicométricas que facilitam uma avaliação sistemática de representação do paciente de acordo com uma abordagem biopsicossocial, além de contribuir para uma prática clínica baseada em evidências científicas.
