There is currently a lack of valid instruments to measure adolescent diabetes numeracy. The Diabetes Numeracy Test (DNT) was adapted for type 1 diabetes and was administered to 2 samples of adolescents. Sample 1 was administered the 39-item version of the DNT (DNT-39) with measures of self-management, responsibility, reading, and glycemic control (A1C). Sample 2 was administered the 14-item version of the DNT (DNT-14) with measures of self-management, responsibility, problem solving, and A1C. Both versions of the DNT showed adequate internal reliability. In Sample 1, the DNT-39 and DNT-14 were related (r = .87, p = .001), and both DNT versions were related to parent education (for DNT-14, r = .31, p = .02; for DNT-39, r = .29, p = .03) and reading (for DNT-14, r = .36, p = .005; for DNT-39, r = .40, p = .001). In Sample 2, the DNT-14 was related to A1C (r = -.29, p = .001), reading skills (r = .36, p = .005), diabetes problem solving (r = .27, p = .02), adolescent age (r = .19, p = .03), and parent education (r = .31, p = .02). In combined analyses, 75% of items were answered correctly on the DNT-14 (range = 7-100), and performance was associated with age (r = .19, p = .03), pump use (r = .33 p = .001), and A1C (r = -.29, p = .001). The DNT-14 is a feasible, reliable, and valid numeracy assessment that indicated adolescents with type 1 diabetes have numeracy deficits that may affect their glycemic control.
目前缺乏有效的工具来衡量青少年的糖尿病算数能力。糖尿病算数测试（DNT）经过改编适用于 1 型糖尿病，对两个青少年样本进行了测试。样本 1 接受了 39 项 DNT 版本（DNT-39）的测试，同时还评估了自我管理、责任感、阅读和血糖控制（A1C）。样本 2 接受了 14 项 DNT 版本（DNT-14）的测试，同时评估了自我管理、责任感、解决问题和 A1C。DNT 的两个版本都表现出足够的内部可靠性。在样本 1 中，DNT-39 和 DNT-14 相关（r =.87，p =.001），并且两个 DNT 版本都与父母教育程度相关（对于 DNT-14，r =.31，p =.02；对于 DNT-39，r =.29，p =.03）和阅读能力（对于 DNT-14，r =.36，p =.005；对于 DNT-39，r =.40，p =.001）。在样本 2 中，DNT-14 与 A1C 相关（r = -.29，p =.001），与阅读技能相关（r =.36，p =.005），与糖尿病问题解决能力相关（r =.27，p =.02），与青少年年龄相关（r =.19，p =.03），与父母教育程度相关（r =.31，p =.02）。在综合分析中，DNT-14 有 75%的题目回答正确（范围为 7-100），且表现与年龄（r =.19，p =.03）、泵的使用（r =.33，p =.001）和 A1C（r = -.29，p =.001）相关。DNT-14 是一种可行、可靠和有效的算数能力评估工具，表明 1 型糖尿病青少年的算数能力存在缺陷，可能会影响他们的血糖控制。
