中文版母婴依恋量表的信效度检验

Validity and Reliability of the Chinese Version of the Maternal Postnatal Attachment Scale

目的:引进母婴依恋量表(Maternal Postnatal Attachment Scale)并对其信、效度进行检验。方法:来自某妇幼保健院的524名产后六周的产妇自愿参与研究。采用项目分析、内容效度指数、结构效度分析、效标关联效度分析和内部一致性信度检验对中文版母婴依恋量表信、效度进行评价。结果:内容效度方面,基于6名专家组成的专业小组评定,内容效度指数为0.93,表明量表具有良好的内容效度。结构效度方面,对其两因子结构模型进行验证性因素分析,各拟合指数达到测量学可接受的范围(χ~2/df=2.85,GFI=0.92,AGFI=0.90,CFI=0.86,RMSEA=0.059,SRMR=0.043)。量表总分与母胎依恋量表和爱丁堡产后抑郁量表的相关分别为0.45和-0.47(均P<0.001)。信度方面,各题目与总分的相关系数为0.32-0.59,且具有显著差异(P<0.001),克朗巴赫α系数为0.73。结论:中文版母婴依恋量表是一个信、效度良好的测量母婴依恋的工具。

Objective： To adapt the Maternal Postnatal Attachment Scale（MPAS） to Chinese and to perform validity and reliability analyses. Methods： A total of 524 women agreed to participate in the study in a maternal and child health care hospital. The validity of content, construct and convergent were examined to evaluate the validity of the MPAS. Cronbach＇ s α was used to assess internal consistency reliability. Results： The consistency of specialist opinion on the scale was deter- mined（CVI=0.93）. The three-factor structure for the original version adapted to the Chinese version. The model fit data well （χ^2/df=-2.85, GFI=0.92, AGFI=0.90, CFI=0.86, RMSEA=O.059, SRMR=0.043）. The MPAS total scores were positively corre- lated with scores of MAAS （r=0.45, P〈0.001） and negatively correlated with EPDS total score （r=-0.47, P〈0.001）. Cron- bach＇s α value was 0.73, which demonstrated high reliability, and the correlation between each item and the composite score ranged from 0.32 to 0.59. Conclusion： The Chinese version of the Maternal Postnatal Attachment Scale is a valid and reliable tool for the evaluation of the early affectionate mother-infant relationship.
