妊娠期糖尿病孕妇社会资源支持量表的研制及信效度检验

目的 研制妊娠期糖尿病孕妇社会资源支持量表并检验其信效度。 方法 基于社会生态模型,通过文献分析、开放式专家咨询、2轮德尔菲函询及预调查形成初始量表;采用便利抽样法,于2021年1月—8月选取福建省3所三级甲等医院的301例妊娠期糖尿病孕妇作为调查对象,对量表进行条目筛选及信效度检验。 结果 妊娠期糖尿病社会资源支持量表包括7个维度、38个条目,加上各维度的重要性评价7个条目,共45个条目;2轮函询的专家积极系数为100%、85.71%,权威系数均为0.879,肯德尔和谐系数为0.218、0.298（均P<0.001）;探索性因子分析共提取7个公因子,累计方差贡献率为63.210%;该量表的Cronbach’s α系数为0.935,重测信度为0.724,内容效度指数为0.970。 结论 妊娠期糖尿病孕妇社会资源支持量表具有良好的科学性和信效度,可作为医护人员评估妊娠期糖尿病孕妇社会支持情况的工具。

Development of a social resource support scale for pregnant women with gestational diabetes and its test of validity and reliability

Objective To develop a social resource support scale of pregnant women with gestational diabetes and to test its reliability and validity. Methods Based on the social-ecological model,the initial scale was formed through literature analysis,open-model expert consultation,and 2 rounds of the Delphi method. The convenience sampling was adopted to select 301 pregnant women with gestational diabetes from January to August 2021 in 3 hospitals in Fujian Province of China. The items screening and the test of reliability and validity were carried out. Results The scale includes 7 dimensions,38 items,and 7 additional evaluation items of various dimensional importance,which come to 45 items in total. The positive coefficients of 2 rounds of letter consultations were 100% and 85.71%;the authority coefficient were all 0.879;the coordination coefficients were 0.218 and 0.298. The Cronbach’s α coefficient was 0.935;the test-retest reliability was 0.724;the content validity was 0.970. The exploratory factor analysis identified 7 principal factors,and the accumulative contribution of variance was 63.210%. Conclusion The social resource support scale of pregnant women with gestational diabetes has good reliability and validity. It can be used as a tool for medical staff to evaluate the social support of pregnant women with gestational diabetes.
