Abstract

Abstract:

Objective To develop a Behavioral Decision-making Scale for Glycemic Management in pregnant women with gestational diabetes and to test its reliability and validity. Methods Based on the trans-theoretical model and behavioral decision theory，the test version of the scale was formed through literature review，semi-structured interview，brainstorming，2 rounds of expert consultation and cognitive interview. A total of 560 pregnant women with gestational diabetes mellitus were recruited from 10 hospitals in Quanzhou，Fujian Province by convenience sampling method from 21 July to November 2023. The data were divided into 2 parts by random number method for exploratory factor analysis and confirmatory factor analysis. Results The scale included 4 dimensions of “behavioral decision-making motivation”“behavioral decision-making influencing factors”“behavioral decision-making intention” and “behavioral decision-making effectiveness” with 34 items. The Cronbach’s α coefficient of the total scale was 0.971；the split-half reliability was 0.919；the test-retest reliability was 0.863；the content validity index of the scale was 0.853. The exploratory factor analysis extracted 4 common factors，and the cumulative variance contribution rate was 78.28%. The confirmatory factor analysis showed that the factor structure of the scale was stable. Conclusion The scale has ideal reliability and validity，which can be used to measure the level of glycemic management behavior decision-making of pregnant women with gestational diabetes mellitus.

摘要：

目的编制妊娠期糖尿病（gestational diabetes mellitus，GDM）孕妇血糖管理行为决策量表，并检验其信效度。方法基于跨理论模型和行为决策理论，通过文献分析、半结构式访谈法、头脑风暴法、2轮专家咨询及认知性访谈法形成测试版量表。采用便利抽样法，于2023年7月21日—11月选取福建省泉州市10所医院的560例GDM孕妇进行调查，运用随机数字法将数据分为2个部分，进行探索性因子分析和验证性因子分析。结果 GDM孕妇血糖管理行为决策量表包括行为决策动机、行为决策影响因素、行为决策意向、行为决策有效性4个维度，34个条目。量表总的Cronbach’s α系数为0.971，折半信度为0.919，重测信度为0.863，内容效度指数为0.853。探索性因子分析提取4个公因子，累计方差贡献率为78.28%；验证性因子分析结果显示，量表因子结构稳定。结论 GDM孕妇血糖管理行为决策量表信效度良好，可用于对GDM孕妇血糖管理行为决策水平的评估。
