In 2005 the Spoken Knowledge in Low Literacy in Diabetes scale (SKILLD) was introduced as a diabetes knowledge test. The SKILLD has not been validated since its introduction.
To perform a validation analysis on the SKILLD.
Cross-sectional observational study of 240 patients with diabetes at an academic family practice center.
SKILLD's correlation with an oral form of the Diabetes Knowledge Test (DKT) was used to assess criterion validity. A regression model tested construct validity, hypothesizing that SKILLD score was independently related to health literacy and education level. Content validity was tested using Cronbach's Alpha for inter-item relatedness and by comparing SKILLD items with the content of a National Institutes of Health (NIH) diabetes education website. We assessed inter-rater reliability and bias using Spearman correlation coefficients and sign-rank tests between interviewers scoring the same interview.
The SKILLD demonstrated fair correlation with the DKT (Pearson's coefficient 0.54, 95% CI=0.49 to 0.66, p<0.001). Health literacy, education level, male gender, household income, and years with diabetes were independent predictors of SKILLD score in the regression model. Cronbach's Alpha for inter-item relatedness was 0.54. There were some topics on the NIH website not addressed by the SKILLD. The inter-rater correlation coefficient was 0.79 (95% CI 0.56 to 0.91, p<0.001).
The SKILLD is an adequate diabetes knowledge test and is appropriate for people of all literacy levels. However, it should be expanded to more completely evaluate diabetes knowledge.
2005 年，引入了口语知识在低文化程度的糖尿病量表（SKILLD）作为糖尿病知识测试。自引入以来，SKILLD 尚未经过验证。
对 SKILLD 进行验证分析。
在学术家庭实践中心对 240 名糖尿病患者进行横断面观察性研究。
SKILLD 与口头形式的糖尿病知识测试（DKT）的相关性用于评估标准效度。回归模型测试结构效度，假设 SKILLD 分数与健康素养和教育水平独立相关。使用 Cronbach's Alpha 测试项目之间的内容有效性，并通过将 SKILLD 项目与美国国立卫生研究院（NIH）糖尿病教育网站的内容进行比较来测试内容有效性。我们评估了评分相同的访谈者之间的评分者间信度和偏差，使用 Spearman 相关系数和符号秩检验。
SKILLD 与 DKT 具有良好的相关性（Pearson 系数为 0.54，95%CI=0.49 至 0.66，p<0.001）。健康素养、教育水平、男性、家庭收入和糖尿病患病年限是回归模型中 SKILLD 评分的独立预测因子。项目之间的 Cronbach's Alpha 为 0.54。NIH 网站上有一些 SKILLD 未涉及的主题。评分者间的相关系数为 0.79（95%CI 0.56 至 0.91，p<0.001）。
SKILLD 是一种足够的糖尿病知识测试，适用于所有文化程度的人群。然而，它应该扩展以更全面地评估糖尿病知识。
