PURPOSE The aim of this study was to develop and validate a scale to measure nursing students’ readiness for the flipped classroom in Sri Lanka. METHODS A literature review provided the theoretical framework for developing the Nursing Students’ Readiness for Flipped Classroom (NSR-FC) questionnaire. Five content experts evaluated the NSR-FC, and content validity indices (CVI) were calculated. Cross-sectional surveys among 355 undergraduate nursing students from 3 state universities in Sri Lanka were carried out to assess the psychometric properties of the NSR-FC. Principal component analysis (PCA, n=265), internal consistency (using the Cronbach α coefficient, n=265), and confirmatory factor analysis (CFA, n=90) were done to test construct validity and reliability. RESULTS Thirty-seven items were included in the NSR-FC for content validation, resulting in an average scale CVI of 0.94. Two items received item level CVI of less than 0.78. The factor structures of the 35 items were explored through PCA with orthogonal factor rotation, culminating in the identification of 5 factors. These factors were classified as technological readiness, environmental readiness, personal readiness, pedagogical readiness, and interpersonal readiness. The NSR-FC also showed an overall acceptable level of internal consistency (Cronbach α=0.9). CFA verified a 4-factor model (excluding the interpersonal readiness factor) and 20 items that achieved acceptable fit (standardized root mean square residual=0.08, root mean square error of approximation=0.08, comparative fit index=0.87, and χ2/degrees of freedom=1.57). CONCLUSION The NSR-FC, as a 4-factor model, is an acceptable measurement scale for assessing nursing students’ readiness for the flipped classroom in terms of its construct validity and reliability.

开发和验证测量量表以评估斯里兰卡护士学生对翻转课堂的准备情况

目的 本研究的目的是开发和验证一个量表，以衡量斯里兰卡护理学生对翻转课堂的准备情况。方法 文献综述为制定护理学生翻转课堂准备 (NSR-FC) 问卷提供了理论框架。五位内容专家对 NSR-FC 进行了评估，并计算了内容有效性指数 (CVI)。对来自斯里兰卡 3 所州立大学的 355 名护理本科生进行了横断面调查，以评估 NSR-FC 的心理测量特性。进行了主成分分析（PCA，n=265）、内部一致性（使用 Cronbach α 系数，n=265）和验证性因素分析（CFA，n=90）来测试结构的有效性和可靠性。结果 NSR-FC 中包含 37 个项目用于内容验证，导致平均规模 CVI 为 0.94。两个项目的项目级别 CVI 低于 0.78。35 个项目的因子结构通过 PCA 与正交因子旋转进行了探索，最终确定了 5 个因子。这些因素分为技术准备、环境准备、个人准备、教学准备和人际关系准备。NSR-FC 还显示了总体可接受的内部一致性水平（Cronbach α=0.9）。CFA 验证了一个 4 因子模型（不包括人际准备因子）和 20 个达到可接受拟合的项目（标准化均方根残差=0.08，近似均方根误差=0.08，比较拟合指数=0.87，χ2/度自由=1.57）。结论 NSR-FC 作为 4 因子模型，
