OBJECTIVES
This study aimed to validate a new consolidated measure of health literacy and numeracy (health literacy scale [HLS] plus the subjective numeracy scale [SNS]) in patients with type 2 diabetes (T2DM).
METHODS
A convenience sample (N = 102) of patients with T2DM was recruited from an academic family medicine center in the southeastern US between September-December 2017. Participants completed a questionnaire that included the composite HLS/SNS (22 questions) and a commonly used objective measure of health literacy-S-TOFHLA (40 questions). Internal reliability of the HLS/SNS was assessed using Cronbach's alpha. Criterion and construct validity was assessed against the S-TOFHLA.
RESULTS
The composite HLS/SNS had good internal reliability (Cronbach's alpha = 0.83). A confirmatory factor analysis revealed there were four factors in the new instrument. Model fit indices showed good model-data fit (RMSEA = 0.08). The Spearman's rank order correlation coefficient between the HLS/SNS and the S-TOFHLA was 0.45 (p < 0.01).
CONCLUSIONS
Our study suggests that the composite HLS/SNS is a reliable, valid instrument.
目的
本研究旨在验证一种新的综合健康素养和算数能力测量工具（健康素养量表[HLS]加主观算数量表[SNS]）在 2 型糖尿病（T2DM）患者中的适用性。
方法
2017 年 9 月至 12 月，我们在美国东南部的一家学术家庭医学中心招募了 102 名 T2DM 患者作为便利样本。参与者完成了一份问卷，其中包括综合 HLS/SNS（22 个问题）和常用的健康素养客观测量工具-S-TOFHLA（40 个问题）。使用 Cronbach's alpha 评估 HLS/SNS 的内部可靠性。使用 S-TOFHLA 评估标准和结构有效性。
结果
综合 HLS/SNS 具有良好的内部可靠性（Cronbach's alpha=0.83）。验证性因子分析显示，新工具中有四个因素。模型拟合指数显示出良好的模型数据拟合（RMSEA=0.08）。HLS/SNS 与 S-TOFHLA 之间的 Spearman 秩相关系数为 0.45（p<0.01）。
结论
我们的研究表明，综合 HLS/SNS 是一种可靠、有效的工具。
