The development of a Health Promotion Literacy Scale within the USR Curriculum is crucial for addressing the existing gap in measuring the impact of USR on students' citizenship and social engagement. This study aimed to develop and assess the psychometric properties of the Health Promotion Literacy-based Scale in USR (HPLS-USR) scale on medical university students through confirmatory factor analysis (CFA) in Taiwan.
We conducted a cross-sectional study and recruited a convenience sample of 405 students in central Taiwan. The HPLS-USR scale, developed by Hung et al. in 2022, comprises four factors-personal growth, responsibility of citizenship, social interaction, and intellectual development-that together accounted for 61.83% of the total variance. Data analysis was performed using SPSS version 26 and AMOS (version 22.0) to perform a CFA to verify the model's goodness of fit.
The modified model derived 17 items in 3 factors, with 51.02% of the total variance explained. The structural equation model displayed a good fit, suggesting that personal growth, responsibility for citizenship, and social interaction were latent variables of the Health Promotion Literacy-based Scale on a USR curriculum. The Cronbach's alphas for the overall scale and the three subscales ranged from 0.82 to 0.93. The psychometric properties of the scale demonstrated good to excellent model fit in the CMIN/DF (χ2/df) = 3.149, GFI = 0.91, AGFI = 0.88, SRMR = 0.04, RMSEA = 0.07, NFI = 0.90, NNFI = 0.92, RFI = 0.89, IFI = 0.93, CFI = 0.93, PNFI = 0.78, and PCFI = 0.81. The Cronbach's alphas ranged between.81 and.89; the composite alphas ranged between.87 and.94.
This study provides preliminary construct validity evidence for the HPLS-USR scale, a robust and psychometrically sound instrument for assessing health promotion literacy among USR students.
在美国研究型大学（USR）课程中开发健康促进素养量表对于弥补目前在衡量USR对学生公民意识和社会参与度影响方面存在的差距至关重要。本研究旨在通过台湾地区的验证性因素分析（CFA），开发并评估基于健康促进素养的美国研究型大学量表（HPLS-USR）对医科大学生的心理测量特性。
我们进行了一项横断面研究，在台湾中部便利抽样招募了405名学生。Hung等人于2022年开发的HPLS-USR量表包含四个因素——个人成长、公民责任、社会互动和智力发展，这四个因素共同解释了总方差的61.83%。使用SPSS 26版和AMOS（22.0版）进行数据分析，以执行CFA来验证模型的拟合优度。
修改后的模型有3个因素共17个项目，解释了总方差的51.02%。结构方程模型显示拟合良好，表明个人成长、公民责任和社会互动是基于健康促进素养的美国研究型大学课程量表的潜在变量。总量表及三个子量表的克朗巴哈系数在0.82至0.93之间。该量表的心理测量特性在CMIN/DF（χ2/df）=3.149、GFI = 0.91、AGFI = 0.88、SRMR = 0.04、RMSEA = 0.07、NFI = 0.90、NNFI = 0.92、RFI = 0.89、IFI = 0.93、CFI = 0.93、PNFI = 0.78和PCFI = 0.81方面显示出良好至优秀的模型拟合。克朗巴哈系数在0.81至0.89之间；组合系数在0.87至0.94之间。
本研究为HPLS-USR量表提供了初步的结构效度证据，该量表是一种用于评估美国研究型大学学生健康促进素养的强大且心理测量健全的工具。
