产前依恋问卷中文版的效度和信度

Validity and reliability of the Chinese version of the Prenatal Attachment Inventory

目的:检验产前依恋问卷中文版(CPAI)的效度和信度。方法:选取孕晚期孕妇共560例。其中280例(样本1)用于条目分析与探索性因子分析,280例(样本2)用于验证性因子分析;选取261例,施测母胎依恋关系量表(MAAS)检验效标关联效度,使用Delphi法检验内容效度。总样本用于测量内在一致性和分半信度。根据自愿原则在4周后选取67例进行重测。结果:量表水平内容效度为0.98。探索性因子分析抽取3因子,累积方差贡献率为52.62%。验证性因子分析显示3因子模型拟合良好(χ^(2)/df=1.89,CFI=0.922,TLI=0.912,RMSEA=0.056,P<0.001,SRMR=0.047);CPAI与MAAS为中度相关(r=0.554,P<0.001)。总量表及三因子内在一致性信度在0.72~0.92之间,重测信度为0.98,分半信度为0.87。结论:产前依恋问卷中文版具有较好的效度和信度。

Objective:To test the validity and reliability the Chinese version of the Prenatal Attachment Inventory(CPAI).Methods:A total of 560 pregnant women in the third trimester of pregnancy were selected.Among them,280 cases(sample 1)were used for item analysis and exploratory factor analysis,and 280 cases(sample 2)were used for confirmatory factor analysis.The Maternal Antenatal Attachment Scale(MAAS)was used to test the criterion-related validity,and the Delphi method was used to test the content validity.The total samples were used to measure the internal consistency and split half reliability.Sixty-seven cases were voluntarily selected and retested after 4 weeks.Results:The scale-level content validity index was 0.98.Three factors were selected by exploratory factor analysis,and the cumulative variance contribution rate was 52.62%.Confirmatory factor analysis showed that the three factors model fitted well(χ^(2)/df=1.89,CFI=0.922,TLI=0.912,RMSEA=0.056,P<0.001,SRMR=0.047).The CPAI scores were moderately correlated with the MAAS scores(r=0.554,P<0.001).The internal consistency reliabilities of the total scale and the three factors ranged from 0.72 to 0.92,and the test-retest reliability was 0.98,the split half reliability was 0.87.Conclusion:The Chinese version of the Prenatal Attachment Inventory has good validity and reliability.
