In China, diabetes has become a serious healthcare problem that plagues individuals and the government because of its high mortality rate and social burden, with type 2 diabetes mellitus (T2DM) accounting for the vast majority (about 90%) of cases. T2DM patients face a huge medication burden and it is imperative to find appropriate tools to assess the medication burden for patients. This study aimed to translate the original Diabetes Treatment Burden Questionnaire (DTBQ) into Chinese and assessed the reliability and validity of the DTBQ concerning the burden of medication treatment in patients with type 2 diabetes.
A total of 329 T2DM patients were recruited to participate in the survey. The original version scale was first translated into Chinese using the backward and forward translation procedures. The internal consistency reliability of the scale was measured by the Cronbach alpha coefficient, the test-retest reliability, and the item-total correlation. The validity of the scale was assessed by the content validity index, exploratory factor analysis and confirmatory factor analysis.
The content validity index of the scale was 0.920. Cronbach alpha coefficient for the scale was 0.831. Exploratory factor analysis (EFA) supported a 15-item and 3-factor structure of the translated questionnaire. Confirmatory factor analysis (CFA) showed in the model fitness index, the chi-square degree of freedom was 3.575, the incremental fit index (IFI) was 0.917, the comparative fit index(CFI) was 0.916, the Tucker Lewis Index(TLI) was 0.900, all within acceptable limits. The retest reliability was 0.892, and the corrected item-total correlations for the items ranged from 0.293 to 0.729.
Verification results showed that the Chinese version of the 15-item DTBQ had reliable reliability and validity. Therefore, it can be considered as an appropriate tool to assess the burden of drug treatment for patients with type 2 diabetes in China.
在中国，糖尿病因其高死亡率和社会负担已成为困扰个人和政府的严重医疗保健问题，其中2型糖尿病（T2DM）占绝大多数病例（约90%）。T2DM患者面临巨大的用药负担，因此必须找到合适的工具来评估患者的用药负担。本研究旨在将原始的糖尿病治疗负担问卷（DTBQ）翻译成中文，并评估DTBQ在2型糖尿病患者药物治疗负担方面的信效度。
共招募329例T2DM患者参与调查。原始版本量表首先采用回译和前译程序翻译成中文。量表的内部一致性信度通过克朗巴哈α系数、重测信度和项目-总分相关性进行测量。量表的效度通过内容效度指数、探索性因子分析和验证性因子分析进行评估。
量表的内容效度指数为0.920。量表的克朗巴哈α系数为0.831。探索性因子分析（EFA）支持翻译后问卷的15项3因子结构。验证性因子分析（CFA）显示，在模型拟合指数中，卡方自由度为3.575，增值拟合指数（IFI）为0.917，比较拟合指数（CFI）为0.916，塔克·刘易斯指数（TLI）为0.900，均在可接受范围内。重测信度为0.892，各项目的校正项目-总分相关性范围为0.293至0.729。
验证结果表明，15项中文版DTBQ具有可靠的信效度。因此，它可被视为评估中国2型糖尿病患者药物治疗负担的合适工具。
