Healthy lifestyle behaviors are at the core of maintaining health. This study analyzed the psychometric properties of the 16-item healthy lifestyle beliefs (HLB) scale that measures a person's beliefs about their ability to live a healthy lifestyle.
Descriptive statistics, exploratory factor analysis, confirmatory analysis, and measurement invariance were conducted for this study.
Cronbach alpha was 0.894. The Exploratory factor analysis scree plot identified two factors with eigenvalues greater than one. All factor loadings were greater than 0.40 and no items cross-loaded. A two-factor solution was retained for Confirmatory factor analysis. The measurement invariance results suggested that there was no gender difference in HLB regarding factor structure, factor loading, threshold, and residual variances.
The HLB scale was found to have adequate internal consistency and fit with the data. Findings show it is valid and acceptable for both boys and girls.
健康的生活方式行为是保持健康的核心。本研究分析了 16 项健康生活信念（HLB）量表的心理测量特性，该量表衡量一个人对自己能够过上健康生活方式的信念。
本研究进行了描述性统计、探索性因素分析、验证性分析和测量不变性分析。
克朗巴赫阿尔法系数为 0.894。探索性因素分析的陡坡图确定了两个特征值大于 1 的因素。所有因子负荷都大于 0.40，没有项目交叉加载。保留了验证性因素分析的两因素解决方案。测量不变性结果表明，HLB 在因子结构、因子负荷、阈值和残差方差方面不存在性别差异。
HLB 量表具有足够的内部一致性和对数据的拟合度。研究结果表明，该量表对男孩和女孩都是有效和可接受的。
