二胎高龄妇女妊娠期需求量表的编制及信效度检验研究

Development,Validity and Reliability of Demands Scale of Women of Advanced Maternal Age during Their Second Pregnancy

目的编制二胎高龄妇女妊娠期需求量表,并对其信效度进行检验。方法采用便利抽样法,选取2016年7—12月盐城市某三级甲等医院门诊产检的孕妇260名。基于马斯洛需求理论,通过孕妇访谈、德尔菲专家咨询,形成初始问卷。采用决断值法和相关系数法筛选条目,并采用内在一致性系数检验量表的信度,内容效度指数和探索性因子分析检验量表的效度。结果初始形成7个维度57个条目量表,经德尔菲专家咨询删除9个条目,删除相关系数<0.400的3个条目,形成由7个维度45个条目组成的二胎高龄妇女妊娠期需求量表。总量表Cronbach'sα系数为0.933,各维度Cronbach'sα系数为0.799~0.937;7个公因子累积方差贡献率为64.08%,各条目因子载荷均>0.400;内容效度指数为0.866。结论二胎高龄妇女妊娠期需求量表具有较高的可靠性,该量表可作为二胎高龄妇女妊娠期需求的评估工具。

Objective To develop and evaluate the validity and reliability of the Demands Scale of Women of Advanced Maternal Age during Their Second Pregnancy（DSWAMATSP）.Methods From July to December 2016,convenience sampling was employed to recruit 260 women of advanced maternal age during their second pregnancy who underwent antenatal examination at the outpatient department of a tertiary grade A hospital in Yancheng,China.Based on Maslow＇s hierarchy of needs,results of the interviews of these women and Delphi expert consultation,we developed the initial DSWAMATSP.Critical value and correlation coefficient were adopted to choose suited items.Cronbach＇s α was adopted to evaluate the reliability of the scale,and content validity and exploratory factor analysis were conducted to evaluate the validity of the scale.Results The initial scale consisted of 7 dimensions and 57 items.Nine items were deleted based on the results of Delphi expert consultation and 3 items whose item-to-dimension correlation coefficients were less than 0.400 were excluded.The final scale contains 45 items in 7 fields.The Cronbach＇s α was 0.933 for the total scale and 0.799 to 0.937 for its subscales.Factor analysis revealed 7 common factors,accounting for 64.08% of the total variance,loading for each factor was over 0.400.The content validity index was 0.866 for the total scale.Conclusion The DSWAMATSP is reliable and can be used as a tool for evaluating the needs of women of advanced maternal age during their second pregnancy.
