读写能力和计算能力低下是很常见的。足够的计算能力对于糖尿病的治疗至关重要。糖尿病患者使用计算技能来解读血糖仪、服用药物、遵循饮食指南和其他任务。现有的识字量表可能不足以评估计算能力。本文介绍了糖尿病算术测试 (DNT) 的发展和心理测量特性，这是第一个专门测量糖尿病中使用的算术技能的量表。 DNT 的项目由专家小组制定，并通过对潜在受访者的认知反应访谈进行完善。 DNT 的最终版本（43 项）和其他相关措施对 398 名糖尿病患者进行了方便抽样。内部可靠性由 Kuder-Richardson 系数 (KR-20) 确定。开发了一个先验假设模型来确定构造有效性。通过分割样本分析创建了缩短的 15 项版本 DNT15。 DNT 具有出色的内部可靠性（KR-20 = 0.95）。 DNT 与教育、收入、识字和数学技能以及糖尿病知识显着相关（p < 0.05），支持出色的结构效度。 DNT 的平均得分为 61%，平均需要 33 分钟才能完成。 DNT15 还具有良好的内部可靠性（KR-20 = 0.90 和 0.89）。在分割样本分析中，两个子样本中 DNT-15 与完整 DNT 的相关性很高（rho 分别 = 0.96 和 0.97）。 DNT 是糖尿病相关计算技能的可靠且有效的衡量标准。 DNT15 是一个同样足够但更省时的 DNT 版本，可用于研究和临床目的，以评估与糖尿病相关的计算能力。
Low literacy and numeracy skills are common. Adequate numeracy skills are crucial in the management of diabetes. Diabetes patients use numeracy skills to interpret glucose meters, administer medications, follow dietary guidelines and other tasks. Existing literacy scales may not be adequate to assess numeracy skills. This paper describes the development and psychometric properties of the Diabetes Numeracy Test (DNT), the first scale to specifically measure numeracy skills used in diabetes. The items of the DNT were developed by an expert panel and refined using cognitive response interviews with potential respondents. The final version of the DNT (43 items) and other relevant measures were administered to a convenience sample of 398 patients with diabetes. Internal reliability was determined by the Kuder-Richardson coefficient (KR-20). An a priori hypothetical model was developed to determine construct validity. A shortened 15-item version, the DNT15, was created through split sample analysis. The DNT had excellent internal reliability (KR-20 = 0.95). The DNT was significantly correlated (p < 0.05) with education, income, literacy and math skills, and diabetes knowledge, supporting excellent construct validity. The mean score on the DNT was 61% and took an average of 33 minutes to complete. The DNT15 also had good internal reliability (KR-20 = 0.90 and 0.89). In split sample analysis, correlations of the DNT-15 with the full DNT in both sub-samples was high (rho = 0.96 and 0.97, respectively). The DNT is a reliable and valid measure of diabetes related numeracy skills. An equally adequate but more time-efficient version of the DNT, the DNT15, can be used for research and clinical purposes to evaluate diabetes related numeracy.
