Development of a Questionnaire Assessing Nurses' Situational Awareness to Missed Care.

This study aimed to develop and validate the Situational Nursing Awareness Probe-Missed Nursing Care Edition (SNAP-MNC) questionnaire, a novel tool designed to assess nurses' situational awareness in the context of missed nursing care. Data were collected from March to October 2022, following a rigorous five-phase questionnaire development process. The five-item questionnaire was developed through literature review and expert evaluation, establishing face and content validity. It was tested with 190 nurses across three shifts. Construct validity was assessed via confirmatory factor analysis, reliability via Cronbach's alpha, and criterion validity by correlating with the MISSCARE survey. The final five-item questionnaire demonstrated suitability for assessing personal situational awareness. The findings established content, construct, criterion validity, and good internal reliability. Confirmatory factor analysis displayed suitable loadings and an excellent fit to a one-dimensional model. Nurses received, on average, low situational awareness scores. The SNAP-MNC effectively assesses nurses' situational awareness, focusing on missed nursing care. This tool evaluates the identification of relevant clinical factors, understanding their implications, and projecting strategies to address challenges, offering actionable insights for improving nursing care quality and outcomes.
