目的：美国糖尿病协会提倡针对青少年I型糖尿病患者的胰岛素治疗方案，包括根据碳水化合物摄入量和血糖水平调整胰岛素剂量。实施这些方案需要了解食物的碳水化合物含量和随后的胰岛素剂量计算，这些技能在实践中可能难以衡量。因此，我们试图开发和验证一份问卷，PedCarbQuiz (PCQ)，以评估青年I型糖尿病患者的碳水化合物和胰岛素剂量知识。研究设计和方法——经过专家小组的研究，对75名患有1型糖尿病的青少年或他们的父母进行了PCQ。信度采用Cronbach alpha和劈开半检验进行评估。为了评估效度，得分与糖化血红蛋白、专家评估、父母教育水平和胰岛素治疗方案的复杂性相关。结果：PCQ平均评分为87±9.7%（范围42-98%）。Cronbach alpha为0.88，两半的相关系数为0.59 （P < 0.0001）。较高的PCQ评分与较低的A1C （r = -0.29, P = 0.01）和专家评估（r = 0.56, P < 0.001）显著相关。父母有大学学历的人得分明显高于没有大学学历的人（P = 0.01），而使用更复杂胰岛素治疗方案的人得分明显高于没有大学学历的人（P = 0.003）。结论：PCQ是一种新颖、易于管理的工具，用于评估碳水化合物和胰岛素给药计算的知识。初步分析支持了PCQ的信度和效度。
OBJECTIVE - The American Diabetes Association advocates insulin regimens for youth with type I diabetes that involve adjusting insulin dose based on carbohydrate intake and blood glucose level. Implementing these regimens requires knowledge about carbohydrate content of foods and subsequent calculations of insulin dose, skills that may be difficult to gauge in practice. Therefore, we sought to develop and validate a questionnaire, the PedCarbQuiz (PCQ), to assess carbohydrate and insulin-dosing knowledge in youth with type I diabetes.RESEARCH DESIGN AND METHODS - After development by an expert panel, the PCQ was administered to 75 youth With type I diabetes or their parents. Reliability was assessed by Cronbach alpha and split-half testing. To assess validity, scores were correlated with A1C, expert assessments, parent educational level, and Complexity of insulin regimen.RESULTS - PCQ mean score was 87 +/- 9.7% (range 42-98%). Cronbach alpha was 0.88, and correlation of split halves was 0.59 (P < 0.0001). Higher PCQ scores correlated significantly with lower A1C (r = -0.29, P = 0.01) and expert assessments (r = 0.56, P < 0.001). Scores were significantly higher in parents With college degrees than in those without (P = 0.01) and in participants with more complex insulin regimens (P = 0.003).CONCLUSIONS - The PCQ is a novel, easily administered instrument to assess knowledge about carbohydrates and insulin dosing calculations. Initial analyses support the reliability and validity of the PCQ.
