To develop and validate a questionnaire to assess diabetes knowledge, attitudes, beliefs, and intent to change among middle school students.
A cross-sectional validation analysis.
Students in 3 urban middle schools in Utah participated in this study.
The 25-item questionnaire was validated in independent samples of 277 and 304 students in the seventh and eighth grades.
The questionnaire includes the following variables: diabetes knowledge, attitudes, beliefs, and intent to change dietary and physical activity behaviors.
Rigorous statistical approaches, including Cronbach's α (goodness of fit) calculation, test-retest reliability, and exploratory and confirmatory factor analyses, were employed to examine the reliability and construct validity.
The Cronbach's α coefficients were 0.7 for both subscales demonstrating acceptable internal consistency. All factor loadings were > 0.4, revealing close relations between factors and items. The confirmatory factor analysis model fit was 0.9 for the comparative fit index and Tucker-Lewis Index, indicating a reasonable model-data fit.
This study demonstrated the validity of a diabetes questionnaire for middle school students. Future work is needed to validate its use in a diabetes prevention program, given the growing need for diabetes education among young adolescents.
开发并验证一份评估中学生糖尿病知识、态度、信念和改变意愿的问卷。
横断面验证分析。
犹他州的 3 所城市中学的学生参与了这项研究。
七年级和八年级各有 277 名和 304 名学生独立参与了 25 项问卷的验证。
问卷包括以下变量：糖尿病知识、态度、信念和改变饮食及体力活动行为的意愿。
采用严格的统计方法，包括克朗巴赫 α（拟合优度）计算、重测信度以及探索性和验证性因素分析，以检验可靠性和结构有效性。
两个分量表的克朗巴赫 α 系数均为 0.7，表明具有可接受的内部一致性。所有因子负荷均>0.4，表明因子与项目之间存在密切关系。验证性因子分析模型的比较拟合指数和塔克-刘易斯指数拟合度为 0.9，表明模型与数据的拟合度合理。
本研究证明了中学生糖尿病问卷的有效性。鉴于青少年对糖尿病教育的需求不断增加，未来需要在糖尿病预防计划中验证其使用。
