工作场所母乳喂养支持研究进展

目的 引进母乳喂养支持的员工感知问卷（EPBS-Q）进行翻译及修订，评价中文版问卷的信效度。 方法 汉化EPBS-Q，并通过专家评定、预调查和认知访谈对中文版问卷进行修订，在郑州市两所三甲医院儿童预防保健门诊，便利抽取产后返岗的346名职业母亲，发放中文版EPBS-Q，评价其信度和效度。 结果 中文版EPBS-Q共包含30个条目，5个维度，总的Cronbach′s α 系数为0.917，5个维度的Cronbach′s α 系数为0.817～0.946，组合信度为0.835～0.994。I-CVI均 > 0.80，S-CVI/Ave为0.99。每个维度的AVE值较高，AVE的算数平方根均大于每个维度之间的相关系数，收敛效度、区别效度和结构效度均较好。 结论 中文版母乳喂养支持的员工感知问卷适用于中国的文化背景，具有良好的信度和效度。

Employer-based programs to support breastfeeding among working mothers: a systematic review

Objective To translate and revise the Employees′ Perceptions of Breastfeeding Support Questionnaire (EPBS-Q) into Chinese, and to assess the reliability and validity of the Chinese version of the EPBS-Q (EPBS-Q-CV). Methods We conducted translation and back translation of EPBS-Q first. Then the developed EPBS-Q-CV was revised through expert assessment, pre-survey and cognitive interviews. Finally, a total of 346 working mothers returning to work at children′s preventive health clinics in two general grade A tertiary hospitals in Zhengzhou city were recruited with convenient sampling and were administered with the revised EPBS-Q-CV to evaluate its reliability and validity. Results The EPBS-Q-CV is composed of 30 items for 5 domains, with the overall Cronbach′s α coefficient of 0.917 and domains′ Cronbach′ s α coefficients ranging from 0.817 to 0.946. The composite reliability of the EPBS-Q-CV was 0.835-0.994 and its content validity index (I-CVI) for items were all > 0.80 and its scale-level content validity index (S-CVI) was 0.99. The values of average variance extracted (AVE) are relatively high for all the 5 domains of the EPBS-Q-CV and the square roots of the 5 domains′ AVE are all greater than the correlation coefficients between each domains, indicating good convergent, differential, and construct validity of the EPBS-Q-CV. Conclusion The developed EPBS-Q-CV is a reliable and valid instrument when applied among Chinese working mothers.
