Validation of the Spanish Version: Expectations and Knowledge Received in the Hospitalized Patient ; Validación de la versión española: Expectativas y conocimiento recibido del paciente hospitalizado ; Validação da versão espanhola do instrumento Expectativa e Conhecimento Recebido do Paciente Hospitalizado

Objective: The objective of the study was to assess the validity and reliability of the Spanish version of Expectations and Received Knowledge in the Hospitalized Patient (ECPH / CRPH), specifically among patients with osteoarthritis who are undergoing total knee ar- throplasty. Material and methods: The validation process followed international recommendations in terms of content validity, construct validity, criterion validity and reliability. A total of 248 patients who were about to undergo total knee arthroplasty at five (5) Spanish public hospitals answered the ECPH before being hospitalized and 220 patients answered the CRPH when they were discharged. Results: Factor analysis confirmed the dimensions of the original scale for the knowledge received, but not with respect to the scale for expectations. The correlation of the ECPH dimensions with the Krantz Health Opinion Scale (KHOS) and the correlation of the CRPH dimensions with the Information Access Scale (AKS) indicated criterion validity, showing positive relationships. The results suggested good reliability with high Cronbach alpha values. Conclusion: The validation process showed the Spanish version of ECPH / CRPH is a valid and reliable instrument to measure the expectations and knowledge received in surgical patients in the Spanish context. ; Objetivo: evaluar la validez y la fiabilidad de la versión española del instrumento Expectativas y conocimiento recibido del paciente hospitalizado (ECPH/CRPH) en pacientes con osteoartritis intervenidos de artroplastia total de rodilla.
