父亲支持母乳喂养自我效能简式量表的汉化与信效度检验

The reliability and validity of the translated Chi nese version of the Father Support Breastfeeding Self-Efficacy Scale-Short Form

目的对父亲支持母乳喂养自我效能简式量表进行汉化,并检验其信效度。方法通过Brislin翻译模型汉化量表,经过文化调试,选取34名产妇配偶进行预测试修改部分条目,在210名产妇及其配偶中测试,检验该量表的信效度。结果中文版父亲支持母乳喂养自我效能简式量表共有14个条目,探索性因子分析提取出1个公因子,累积方差贡献率为55.038%。验证性因子分析显示,修正后的模型各项指标均达到标准,模型拟合度良好。总量表的Cronbach’sα系数为0.935,折半信度为0.930,重测信度为0.881。该量表各条目水平的内容效度指数为0.83~1.00,量表水平的内容效度指数为0.976,各条目间相关系数为0.389~0.643,各条目与量表总分间的相关系数为0.633~0.798,具有统计学意义(均P<0.01)。结论中文版父亲支持母乳喂养自我效能简式量表是评估新生儿父亲对母乳喂养信心的有效工具,量表得分可以预测产妇喂养方式,有助于临床护理人员通过干预新生儿父亲态度来改善产妇喂养信心。

Objective To translate and revise the Father Support Breastfeeding Self-Efficacy Scale-Short Form(BSES-SF),and to test its reliability and validity. Methods By using the Brislin translation model to interpret the scale into Chinese,the experts modified it based on Chinese culture and 34 maternal spouses were selected to preinvestigate and modify some items. Clinically,210 postnatal mothers and their spouses were selected to test the reliability and validity of the scale. Results There were 14 items in the Chinese FBSES-SF scale. One factor was extracted after the exploratory factor analysis,and the factor cumulative variance contribution rate was 55.038%. The result of confirmatory factor analysis has showed that the total scale and subscales fitted well with the structure model. The Cronbach’s α coefficient of the total scale was 0.935;the half-fold reliability of the total scale was0.930;the test-retest was 0.811. The Scale-Content Validity Index(S-CVI) was 0.976;the Item-Content Validity Index(I-CVI) ranged from 0.83 to 1.00;the correlation coefficient between each factor ranged from 0.389 to 0.643;the correlation coefficient between each factor and the total score of the scale ranged from 0.633 to 0.798. All of the analysis above showed statistical significance(P<0.01). Conclusion The Chinese version of FBSES-SF scale is an effective tool for assessing father’s self-confidence in maternal breastfeeding. The scale score can predict the maternal feeding pattern. The low score exhibits a dangerous signal to stop breastfeeding earlier in the postpartum period. It helps clinical experts to increase maternal feeding confidence by intervening the attitudes of new fathers.
