Resumo
Objetivo: Desenvolver um roteiro de entrevista sobre o conhecimento em Insuficiência Cardíaca (IC), crenças sobre Diretivas Antecipadas (DAs) e a intenção de preencher as DAs, bem como avaliar sua validade de conteúdo e de face. Métodos: Estudo de métodos mistos desenvolvido em três etapas: Etapa 1) Estudo metodológico de desenvolvimento do roteiro baseado nas diretrizes brasileiras de IC, no modelo brasileiro de DAs e na Teoria do Comportamento Planejado. Etapa 2) Avaliação da validade de conteúdo por seis especialistas, que avaliaram os itens quanto à relevância prática, clareza, relevância teórica e dimensionalidade. Todos os itens com valores de Índice de Validade de Conteúdo (IVC) < 80% foram revisados e reavaliados. Etapa 3) Avaliação da validade de face por meio de teste cognitivo (estudo-piloto) realizado com 20 pacientes com IC em acompanhamento ambulatorial. Resultados: O roteiro incluiu 11 itens sobre conhecimento em IC e 21 itens sobre crenças e intenção de preencher as DAs. Treze itens foram revisados na Etapa 2, alcançando IVC > 80% e AC2 de Gwet > 0,80. Os pacientes relataram dificuldades com itens sobre crenças comportamentais, normativas e de controle, sugerindo a necessidade de educação prévia sobre as DAs. Conclusões: O roteiro apresentou validade de conteúdo e de face satisfatórias. Ele pode auxiliar enfermeiros e outros profissionais de saúde a identificar lacunas de conhecimento e crenças que influenciam o preenchimento das DAs, apoiando a autonomia do paciente e a tomada de decisão informada nos cuidados de fim de vida.
