WOICE测量工具孕期问卷的汉化及信效度检验

Sinicization of maternal WOICE tool:antenatal women and the evaluation of reliability and validity

目的对WOICE测量工具孕期问卷进行汉化并信效度检验,为孕期健康水平评估提供科学的测量工具。方法采用Brislin经典回译模型进行问卷汉化,并选取2020年9月1日至2021年3月30日于复旦大学附属妇产科医院进行产检的孕妇进行问卷调查。根据调查结果进行汉化问卷的信效度检验,信度检验用Cronbach′sα系数、折半信度和重测信度进行评价,效度检验主要评价内容效度和效标效度。结果本次研究回收有效问卷609份(98.5%);总问卷Cronbach′sα系数、折半系数和重测系数分别为0.780、0.751和0.792,生活功能损伤自评量表(WHODAS 2.0)、广泛性焦虑障碍量表(GAD-7)、简单自测抑郁量表(PHQ-9)、孕产疾患生理症状自报表各部分的Cronbach′sα系数均>0.8;除孕产疾患生理症状自报表的折半系数为0.686外,其余折半系数和重测系数均>0.7;相关分析显示WHODAS 2.0、GAD-7、PHQ-9各量表总得分与内部各条目得分具有正相关性,且差异具有统计学意义(r值分别介于0.463~0.696、0.566~0.763、0.480~0.792之间,P<0.05);对"水肿"和"体重增长过快"分别检验效标效度,结果显示关联系数为0.532和0.472,具有良好的效度。结论中文版WOICE测量工具孕期问卷在我国人群应用上有良好的信效度,可用于评价孕期妇女的孕产健康水平。

Objective To sinicize maternal WOICE tool: antenatal care, and to evaluate its reliability and validity, so as to provide a set scientific measurement tool for evaluating maternal health during pregnancy.Methods The Brislin classic back-translation model was used to translate the questionnaire into Chinese, and the questionnaire survey was conducted on pregnant women who had undergone an obstetric check-up at the obstetrics & gynecology hospital of Fudan University from September 1,2020 to March 30,2021.The reliability and validity of the questionnaire were evaluated accoriding to the survey results, Cronbach′s α,split-half reliability and test-retest reliability were used to evaluate the reliability, and validity mainly evaluated content validity and criterion validity.Results 609 valid questionnaires were collected with an effective rate of 98.5%.The Cronbach′s α coefficient, split-half reliability and test-retest reliability of the total questionnaire were 0.780,0.751 and 0.792,respectively.The Cronbach′s α coefficients of WHO Disability Assessment Schedule 2.0(WHODAS 2.0),Generalized Anxiety Disorder 7-item(GAD-7),Patient Health Questionnaire 9-item(PHQ-9) and the self-report of physical symptoms of maternal morbidity were all greater than 0.8.Except for the split-half reliability of the self-report of physical symptoms of maternal morbidity, which was 0.686,the rest of the split-half reliability and test-retest reliability of each part were all greater than 0.7.The correlation analysis showed the total scores of WHODAS 2.0,GAD-7 and PHQ-9 were positively correlated with the internal items, and the differences were statistically significant(r=0.463-0.696,0.566-0.763,0.480-0.792,respectively P<0.05).For criterion-related validity of “odema” and “rapid weight gain”,the correlation coefficients were 0.532 and 0.472,showing good validity.Conclusion The Chinese version of the maternal WOICE tool: antenatal care has good reliability and validity in the application of the Chinese population, and can be used to evaluate maternal health of pregnant women.
