    Abstract:
    BACKGROUND: Disaster nursing education is a necessity for nurses and students to improve their disaster relief competencies. Determining undergraduate student nurses' learning perceived needs for disaster nursing can help improve curricula construction. In China there is currently no valid instrument available for the evaluation of influencing factors. A disaster nursing course content system was developed using the Delphi method in 2011. However, this system was unformed and lacked psychometric evaluation. OBJECTIVES: To adapt the disaster nursing course content system into an instrument, to evaluate its psychometric properties, and to investigate undergraduate student nurses' learning perceived needs for disaster nursing. DESIGN, SETTINGS AND PARTICIPANTS: Two cross-sectional studies were conducted in public higher education institutions in China. In the first study, a total of 1714 undergraduate student nurses were recruited in May to October 2016; in the second study, 68 were recruited in May 2019. METHODS: The instrument was adapted through literature review, face validity and pilot testing in preliminary studies. The construct validity and reliability of the instrument were tested using exploratory factor analysis, parallel analysis, confirmatory factor analysis, internal consistency reliability and test-retest reliability. RESULTS: The exploratory factor analysis and parallel analysis extracted a three-factor solution comprising 19 items that accounted for 71.69% of the total variance, including discipline introduction, skills and knowledge in disaster relief, and disaster management. The fit indices indicated a good fit. The internal consistency and test-retest reliability was good, as indicated by a Cronbach's alpha of 0.89 and an intraclass correlation coefficient of 0.87. CONCLUSION: The Learning Needs for Disaster Nursing questionnaire exhibited good psychometric properties, thereby proving itself a valuable instrument for evaluating learning perceived needs in undergraduate student nurses.
