摘要: 背景 健康素养与健康状况密切相关,目前国内研究多倾向于运用多维度、多条目的健康素养测评工具,尚缺少简便且有效的健康素养测评工具。 目的 简化健康素养量表并在中国人群中进行心理测量学检验。 方法 从"中国家庭健康指数调查(2021年)"数据中选择18岁及以上人群作为本研究的调查对象,依据纳入与排除标准,最终纳入7 449份数据,并随机分为2个样本集,其中样本集1共3 680份,样本集2共3 769份。对调查对象进行一般资料问卷、12条目健康素养量表(HLS-SF12)、领悟社会支持量表(PSSS)、家庭健康量表(FHS-SF)调查。应用经典测量理论以及项目反应理论中的Mokken模型对HLS-SF12原条目进行筛选,并对精简后的量表进行信效度等验证性分析。 结果 使用经典测量理论和Mokken模型分别简化出1个9条目版本的量表(HLS-SF9)和1个4条目版本的量表(HLS-SF4)。HLS-SF9与HLS-SF4均无天花板效应、地板效应,二者的Cronbach's α系数分别为0.913和0.842,折半信度分别为0.871和0.815。HLS-SF4经探索性因子分析提取出1个公因子,累积方差贡献率为67.813%,各条目的因子载荷量均>0.81。HLS-SF9经验证性因子分析结果显示χ2/df=10.844、拟合优度指数(GFI)=0.985、调整拟合优度指数(AGFI)=0.971、规范拟合指数(NFI)=0.986、比较拟合指数(CFI)=0.987和近似误差均方根(RMSEA)=0.051。相关性分析结果显示,HLS-SF9、HLS-SF4与PSSS呈正相关(r=0.367、0.292,P<0.001),与FHS-SF呈正相关(r=0.340、0.237,P<0.001)。HLS-SF9对HLS-SF12的效标效度的一致性水平(ICC)(95%CI)为0.989(0.988~0.999),HLS-SF4效标效度的ICC(95%CI)为0.892(0.886~0.899)。 结论 简化后的健康素养量表具有良好的信效度,是能够快速测评中国人群健康素养的有效工具,研究者可根据研究精度(HLS-SF9)或测评时间(HLS-SF4)的需求采取针对性选择。

Abstract:

Background

Health literacy is closely associated with health status, most domestic studies tend to use multidimensional and multi-item tools for assessing health literacy, lacking simple and effective assessment methods.

Objective

To simplify health literacy scale and conduct psychometric test within the Chinese population.

Methods

Adults aged 18 years and above were selected from the "China Family Health Index Survey (2021) " for this investigation. Based on inclusion and exclusion criteria, a total of 7 449 participants were selected and randomly divided into two sample sets, including 3 680 cases in sample set 1 and 3 769 cases in sample set 2. The general information questionnaire, Short-form Health Literacy Questionnaire (HLS-SF12), Perception Social Support Scale (PSSS), and Family Health Scale Short-form (FHS-SF) were administered to the respondents. Classical test theory (CTT) and the Mokken model in item response theory (IRT) were used to screen the original items, and validation analyses such as reliability and validity of the simplified scales were also conducted.

Results

A 9-item version (HLS-SF9) and a 4-item version (HLS-SF4) were simplified by using CTT and the Mokken model, respectively. Both the HLS-SF9 and the HLS-SF4 had no ceiling effect or floor effect, and the Cronbach's α coefficients for both were 0.913 and 0.842, with split-half reliabilities of 0.871 and 0.815, respectively. The exploratory factor analysis of HLS-SF4 revealed one common factor, accounting for 67.813% of the cumulative variance, with factor loadings exceeding 0.81 for each item. The confirmatory factor analysis of HLS-SF9 showed that χ2/df was 10.844, goodness of fit index (GFI) was 0.985, adjusted goodness of fit index (AGFI) was 0.971, normative fit index (NFI) was 0.986, comparative fit index (CFI) was 0.987, and root mean squared error of approximation (RMSEA) was 0.051. The correlation analysis demonstrated positive correlation of HLS-SF9 and HLS-SF4 with PSSS (r=0.367, 0.292, P<0.001), as well as FHS-SF (r=0.340, 0.237, P<0.001), respectively. The intraclass correlation coefficients (ICC) (95%CI) for the criterion validity of HLS-SF9 against HLS-SF12 was 0.989 (0.988-0.999), while for HLS-SF4 against HLS-SF12 was 0.892 (0.886-0.899) .

Conclusion

The simplified health literacy scales have good reliability and validity, which are reliable and effective tools for assessing the health literacy of the Chinese population. Researchers can choose the scale according to the needs of research precision (HLS-SF9) or assessment time (HLS-SF4) .
