Abstract:

Objective To develop a blood glucose management protection motivation questionnaire for patients with gestational diabetes mellitus（GDM） and to test its reliability and validity. Methods Based on Protection Motivation Theory and according to the "Clinical Nursing Practice Guideline for Gestational Diabetes Mellitus",the primary questionnaire was formulated through literature review,patient semi-structured interviews and expert consultations. 7 experts and 408 patients with GDM were selected to test the reliability and validity. Results The protection motivation questionnaire contains 35 items in 7 dimensions. The content validity index of the questionnaire was 0.976. Cronbach’s α coefficients of the questionnaire was 0.901 and split-half reliability of the questionnaire was 0.965;Cronbach’s α coefficients of 7 dimensions ranged from 0.850 to 0.953 and split-half reliability of 7 dimensions ranged from 0.905 to 0.961. Exploratory factor analysis identified 7 principal factors,which accumulatively explained 75.32% of total variance. Confirmatory factor analysis indicated good model fit. Conclusion Blood glucose management protection motivation questionnaire has good reliability and validity,which can be used to evaluate GDM pregnant women’s blood glucose management protection motivation,and to analyze and predict their blood glucose management behavior.

摘要：

目的 编制妊娠期糖尿病孕妇血糖管理保护动机问卷并检验其信效度。 方法 以保护动机理论为基础,根据《妊娠期糖尿病临床护理实践指南》,通过文献回顾、患者半结构式访谈、专家咨询编制问卷初稿。通过咨询7名专家及调查408例妊娠期糖尿病孕妇对问卷信效度进行检验。 结果 妊娠期糖尿病孕妇血糖管理保护动机问卷包含7个维度,共35个条目,问卷内容效度指数为0.976,Cronbach’s α系数为0.901,折半信度为0.965;各维度的Cron-bach’s α系数为0.850~0.953,折半信度为0.905~0.961。探索性因子分析共提取7个公因子,累计方差贡献率为75.32%。验证性因子分析显示,模型拟合度良好。 结论 妊娠期糖尿病孕妇血糖管理保护动机问卷具有良好的信效度,可用于妊娠期糖尿病孕妇血糖管理保护动机的评估及血糖管理行为的分析和预测。
