Abstract

Background: Adequate health literacy can lead to self-care behaviors among patients with type 2 diabetes (T2D). Although there is an instrument for measuring the health literacy of patients with diabetes, there is no Persian version of the instrument in Iran.

Objectives: The aim of this study was to translate the Chinese Health Literacy Scale for Diabetes (CHLSD) and evaluate the psychometric parameters of the Iranian version.

Methods: In this methodological study, using a standard forward-backward translation procedure, the original English language version of the questionnaire was translated into Persian. Face and content validity steps were performed for psychometric measurements. To perform construct (convergent) validity, a cross-sectional study was carried out with the participation of T2D patients admitted to the diabetes clinic (aged over 25 years old). To test the reliability, internal consistency was assessed by Kuder-Richardson (K-R) coefficient, and a test-retest was performed by Spearman correlation coefficient.

Results: A total of 283 patients with T2D (mean age: 52.4 years and standard deviation: 11.5) were included in the study. The factor loadings of the variables were checked by calculating the correlation value of the characteristics of a construct with that construct, whose value was greater than 0.4. The K-R coefficients for the whole instrument and its four subscales (remembering, application, analysis, and comprehension) were 0.8, 0.71, 0.73, 0.87, and 0.89, respectively. Re-testing of the instrument with an interval of two weeks indicated the acceptable stability of the instrument (ICC ≥ 0.8).

Conclusions: Our findings showed that the Iranian version of CHLSD is a valid and reliable instrument for measuring the health literacy in patients with diabetes.

2型糖尿病健康素养评估工具:伊朗版的翻译和心理测量学评估

背景:充分的健康素养可以提高2型糖尿病患者的自我保健行为。虽然有一种测量糖尿病患者健康素养的工具，但伊朗没有波斯语版本的工具。目的:本研究的目的是翻译中国糖尿病健康素养量表(CHLSD)，并评估伊朗版本的心理测量参数。方法:在本方法学研究中，采用标准的前向后翻译程序，将问卷的原始英文版本翻译成波斯语。对心理测量进行了面部和内容效度步骤。为了执行结构(收敛)效度，我们对在糖尿病诊所就诊的T2D患者(年龄在25岁以上)进行了横断面研究。为检验信度，采用库德-理查德森(K-R)系数评估内部一致性，采用Spearman相关系数进行重测。结果:共纳入283例T2D患者，平均年龄52.4岁，标准差11.5。通过计算构念特征与构念的相关值来检验各变量的因子负荷，其相关值大于0.4。整个工具及其四个子量表(记忆、应用、分析和理解)的K-R系数分别为0.8、0.71、0.73、0.87和0.89。仪器每隔两周重新测试一次，表明仪器的稳定性可接受(ICC≥0.8)。结论:伊朗版CHLSD是一种有效、可靠的糖尿病患者健康素养测量工具。
