摘　　要：目的：对产后生存质量量表条目池（含101个条目）进行条目筛选,保留可以使整个量表更可靠、准确的条目,从而形成最后简化的产后生存质量量表。方法：请10名妇幼卫生领域专家对条目池中101个条目的重要性进行评分,并用条目池对200名产后0 -12个月妇女进行横断面调查,选取其中10%的调查对象在1个月内进行重测。在这些数据基础上,运用专家评分法、因子分析法、离散程度法、克龙巴赫系数（Cronbach Alpha）法、相关系数法（包括2种）和重测信度法分别进行条目筛选,然后汇总各方法的筛选结果,保留至少在5种方法的筛选下,都能入选的条目,组成最终的量表。结果：在7种筛选中,达到相应删除标准的条目数量分别为：主观评分法,删除39条;因子分析法,删除43条;离散程度法,删除49条;克龙巴赫系数法,删除50条;相关系数法1,删除26条;相关系数法2,删除9条;重测信度法,删除11条。结果有60个条目保留。为进一步精简条目数量,在每个方面只选择入选次数相对较多的两个条目,最后保留了40个条目组成量表。结论：精简后的量表距离推广运用还有一定差距,还需在其他人群中进行信度和效度检验。Objective：To select items to compose the final scale from 101-item pool for assessment of postnatal quality of life which was developed by the authors before. Methods： Ten experts in maternal and child health scored the importance of every item. A total of 200 women at 0 - 12 months after childbirth who took their babies for vaccination or clinic services were investigated by the item pool, and 10% of them were retested in one month. Based on these data, items in the item pool were screened by following principles respectively： score of item importance, factor loading, variation coefficient, Cronbaeh Alpha, correlation coefficient of item with domains （2 types） and test-retest correlation coefficient. Then we summarized the screening results of these methods, and retained the items which could be selected in at least five methods. Results： The numbers of items deleted in these seven screening methods respectively were： 39 items in experts scoring method; 43 items in factor analysis method; 49 items in variation analysis method; 50 items in Cronbaeh Alpha method; 26 items in correlation coefficient method 1; 9 items in correlation coefficient method 2; and 11 items in test-retest method. After summarizing these screening results, 60 items were selected. In order to simplify the scale,only kept 2 items in each aspect which had more frequency retained. Finally, 40 items remained in the postnatal quality of life scale. Conclusion： This is the first Chinese scale for evaluating postnatal quality of life of women. It needs to establish the validity and reliability in the future.
