To investigate the reliability and validity of Healthy Fitness Measurement Scale Version 1.0 (HFMS V1.0) for different population cohorts in the city of Guangzhou, Guangdong, China and to provide evidence and tools for further evaluation of healthy fitness of Chinese population and related factors.
Cross-sectional study.
Urban neighbourhood and Medical University.
Elderly people (n=393; mean age 68.27±6.38 years; 53.18% male), university students (n=390; mean age 19.29±1.29 years; 38.21% male) and urban residents (n=393; mean age 32.23±9.41 years; 44.78% male).
The primary outcomes were evaluated the reliability and validity of HFMS V1.0 by internal consistency evaluation, split-half reliability, test-retest reliability, convergent and discriminant construct validity, and factor analysis.
The Cronbach's α coefficients for HFMS V1.0 were all greater than 0.85 for overall scale of total samples and three individual groups, and the split-half reliability and intragroup correlation coefficients were both greater than 0.70 (p<0.01). The correlation of each item, dimension and subscales ranged from 0.52 to 0.91 ( < 0.01). A total of 10 factors were screened by exploratory factor analysis with the cumulative contribution rate of 61.40%, basically consistent with the theoretical structure of scale. The confirmatory factor analysis indicated good fit: CMIN/DF=3.45, root mean square error of approximation=0.05, GFI=0.91, AGFI=0.90, IFI=0.90, comparative fit index=0.90.
HFMS V1.0 showed acceptable reliability and validity in the test of healthy fitness of general population in Guangzhou. This scale could be a reliable measurement tool for evaluation of healthy fitness and potential risk factors.
调查中国广州市不同人群队列中健康健身测量量表 1.0 版（HFMS V1.0）的可靠性和有效性，并为进一步评估中国人群的健康健身状况及相关因素提供证据和工具。
横断面研究。
城市社区和医科大学。
老年人（n=393；平均年龄 68.27±6.38 岁；53.18%为男性）、大学生（n=390；平均年龄 19.29±1.29 岁；38.21%为男性）和城市居民（n=393；平均年龄 32.23±9.41 岁；44.78%为男性）。
主要结果是通过内部一致性评估、半分可靠性、重测信度、聚合和区分性结构有效性以及因子分析来评估 HFMS V1.0 的可靠性和有效性。
HFMS V1.0 的总体量表和三个单独组的克朗巴赫's α 系数均大于 0.85，半分可靠性和组内相关系数均大于 0.70（p<0.01）。每个项目、维度和子量表的相关性均在 0.52 到 0.91 之间（<0.01）。探索性因子分析共筛选出 10 个因子，累计贡献率为 61.40%，基本符合量表的理论结构。验证性因子分析表明拟合良好：CMIN/DF=3.45，近似均方根误差=0.05，GFI=0.91，AGFI=0.90，IFI=0.90，比较拟合指数=0.90。
HFMS V1.0 在广州普通人群健康健身测试中表现出良好的信度和效度。该量表可作为评估健康健身状况和潜在危险因素的可靠测量工具。
