围生期产妇健康素养量表条目筛选

目的：对围生期产妇健康素养量表条目池进行条目筛选，形成条目更可靠、更准确的围生期产妇健康素养量表。方法：运用Delphi法，请14名妇幼专家对研究者自行编写的56个条目的需要性和重要性进行两轮函询，保留50个条目。用该条目池对350名产后1~3 d的产妇进行横断面调查，选取其中10%的调查对象1周后重测。在这些数据基础上，运用χ2检验法、相关系数法(2种)、因子分析法、Cronbach’s α系数法、重测信度法6种方法进行条目筛选，保留3种或3种以上方法均不需删除的条目，组成最终量表。结果：重测结果Person相关系数为0.507(P=0.004)。通过6种筛选方法删除的条目数量分别为：1)χ2检验法删除9条；2)相关系数法1删除25条；3)相关系数法2删除1条；4)Cronbach’s α系数法删除19条；5)因子分析法删除8条；6)重测信度法删除37条。最终由33个条目组成围生期产妇健康素养量表。结论：运用6种条目筛选方法获得了精简后的量表，但距离推广应用还有很大距离，需要在人群中进行大样本调查，进行信效度检验。

Item selection for perinatal maternal health literacy scale

Objective: To establish a more reliable and accurate scale of perinatal maternal health literacyduring perinatal period by selecting items form existing scale.Methods: Two rounds of inquiry were performed by 14 experts on mother and children to evaluatethe necessary and importance of 56 items by Delphi method, in which 50 items were retained. Th enwe proceeded a cross-sectional survey in 350 woman who just gave birth 1–3 days before. 10% ofthem were selected to retest aft er 1 week. Based on these data, we used 6 diff erent methods to selectitems and kept those that could pass by at least 3 different methods. The methods used in dataanalysis were Chi-square test, correlation coefficient method (2 kinds), factor analysis, Cronbach αcoefficient method and the retest reliability method.Results: The Person correlation coefficient was 0.507 (P=0.004). By using the 6 statistical methods,we deleted 9 items through Chi-square test, 25 items through correlation coefficient method 1, 1item through correlation coefficient method 2, 19 items through Cronbach α coefficient method, 8items through factor analysis and 37 items through retest reliability method. In the end, 33 items wereretained for the novel scale of maternal health literacy during perinatal period.Conclusion: Simplified novel scale is acquired, which need to do large efforts before extensive use,such as large sample survey, reliability and validity test.
