不孕症女性生育动机量表的编制及信效度检验

Development of reproductive motivation scale for infertile women and its reliability and validity

目的初步编制适用于不孕症女性群体的生育动机量表(fertility motivation scale for infertile women,FMS-IW),并检验其信效度。方法基于自我决定理论和需要层次理论编制量表,在临床心理咨询实践经验基础上,结合文献阅读、咨询临床心理治疗专家、对不孕症女性进行的访谈和开放式问卷等资料,建立量表条目池,选取257名被试进行项目分析和探索性因子分析形成初始版量表;采用德尔菲法建立FMS-IW正式版;选取392名被试正式施测,进行验证性因子分析及信度检验;间隔2周随机抽取56名被试进行重测。利用SPSS 25.0和Amos 24.0进行Spearman相关分析、探索性因素分析和验证性因素分析。结果探索性因素分析显示,FMS-IW由控制型生育动机和自主型生育动机2个因子共16个条目组成,累计方差贡献率为64.18%;验证性因素分析显示模型拟合良好(χ^(2)/df=3.292,RMSEA=0.077,SRMR=0.055,GFI=0.902,AGFI=0.871,IFI=0.938,CFI=0.938,TLI=0.928);FMS-IW的Cronbach'sα系数为0.908,控制型生育动机和自主型生育动机的Cronbach'sα系数分别为0.911和0.928。FMS-IW Spearman-Brown折半系数为0.870,重测信度Cronbach'sα系数为0.823。结论FMS-IW信度和效度较好,可作为测量不孕症女性生育动机的有效工具。

Objective To preliminarily develop a fertility motivation scale for infertile women(FMS-IW)and test its reliability and validity.Methods The FMS-IW was developed according to the theory of self-determination and Maslow's hierarchy of needs,and the original item pool was established through clinical psychological counseling practice experience,literature review,consulting clinical psychotherapists,interviewing with infertile women and open-ended questionnaires.The original scale was constructed on item analysis and exploratory factor analysis in 257 infertile women.The formal version of FMS-IW was further adapted by Delphi method and tested in another 392 women to conduct confirmatory factor analysis and reliability test.Furthermore,56 participants of 392 women were randomly retested with FMS-IW after two weeks.SPSS 25.0 and Amos 24.0 software were used for Spearman analysis,exploratory factor analysis and confirmatory factor analysis.Results Exploratory factor analysis showed that the FMS-IW was composed of 16 items consisting of two factors:autonomous fertility motivation and controlled fertility motivation.The cumulative variance contribution rate was 64.18%.Confirmatory factor analysis showed that the model fitted well(χ^(2)/df=3.292,RMSEA=0.077,SRMR=0.055,GFI=0.902,AGFI=0.871,IFI=0.938,CFI=0.938,TLI=0.928).The Cronbach'sαcoefficient of the FMS-IW was 0.908.The Cronbach'sαcoefficient for autonomous and controlled fertility motivation was 0.911 and 0.928,respectively.The parity split-half coefficient of the formal version of FMS-IW was 0.870.The test-retest reliability of the formal version of FMS-IW was 0.823.Conclusion The FMS-IW has good reliability and validity,and can be used as an effective tool to measure fertility motivation in infertile women.
