Validação da versão Brasileira da Evidence-based Practice Knowledge Assessment in Nursing (EKAN)

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO

Objetivo

A Evidence-based Practice Knowledge Assessment in Nursing (EKAN) é uma medida objetiva do conhecimento sobre prática baseada em evidência (PBE). Os objetivos do projeto foram traduzir a EKAN para o português do Brasil, testar suas propriedades psicométricas e documentar avaliação de linha de base do conhecimento de estudantes sobre a PBE.

Método

A EKAN–Versão Brasileira foi aplicada a estudantes de dois programas de bacharelado em enfermagem e os dados foram submetidos a análise de Rasch.

Resultados

Participaram 123 estudantes (87%-idades entre 19-25 anos; 60%-primeiro ano; 38% sem exposição prévia a conteúdo de PBE). Índices de validade: dificuldade média = -2,48 a 2,07; Infit (WMS) médio = 0,985 (DP = 2,13); Outfit (UMS) médio = 0,975 (DP = 0,17). Índices de confiabilidade mostraram índice de separação suficiente (4,47); de separação de pessoa moderado (0,47); alta confiabilidade dos itens (0,95); baixa confiabilidade de pessoas (0,18). O escore médio na EKAN (máximo = 20) foi 7,6 (DP = 2,13).

Conclusão

Esse estudo produziu evidências de validade e confiabilidade da EKAN-Versão Brasileira; a confiabilidade de pessoas mostrou a necessidade de incorporar conceitos e conteúdos sobre a PBE nos programas de enfermagem.
