Abstract

Purpose ‐ To introduce a cognitive approach ‐ cognitive task analysis (CTA) ‐ for the usability evaluation of evidence-based nursing (EBN) websites. Design/methodology/approach ‐ With the justification of the need for new evaluation methodologies for the usability of EBN websites and the provision of the theoretical framework and implications of CTA, the author proposes detailed steps for the usability evaluation of EBN websites. Findings ‐ CTA is a new approach that can be used for the evaluation of the usability of EBN websites. It has the advantages that conventional evaluation methods lack in characterizing the aspects of websites useful to nurses in carrying out evidence-based practices. Originality/value ‐ This paper, with the introduction of a new cognitive approach, helps ensure the effective evaluation of the EBN websites, which can then be improved to adequately meet the requirements and information processing needs of the nurses practising evidence-based nursing.
