Abstract: Objective: To develop a questionnaire to evaluate clinical nurses' knowledge, attitudes, and practices in recognizing and managing in-hospital stroke, providing a validated tool to assess their current competencies in stroke identification and emergency care. Methods: Based on the Knowledge-Attitude-Practice theory, the item pool of the questionnaire was established through a comprehensive approach, which encompassed an in-depth literature review, Delphi expert consultations, and pilot survey. Subsequently, a total of 448 clinical nurses were surveyed by using convenience sampling method in Ganzhou in October 2024 to conduct item analysis as well as reliability and validity tests on the questionnaire. Results: The final questionnaire consisted of 34 items in 3 dimensions. The content validity at the item level ranged from 0.830 to 1.000, and the average content validity of the questionnaire was 0.960. Exploratory factor analysis extracted a total of 6 common factors, with a cumulative variance contribution rate of 60.225%. Confirmatory factor analysis showed that the factor loading of each item ranged from 0.532 to 0.837, indicating a good model fit. The overall Cronbach's α coefficient of the questionnaire was 0.943, the test-retest reliability was 0.933, and the split-half reliability was 0.765. Conclusion: This questionnaire, which demonstrates good reliability and validity, can thus be employed as an instrument for comprehensively assessing the knowledge, attitude, and practice levels of clinical nurses in relation to in-hospital stroke recognition and management.
