中文版Braden QD压力性损伤风险评估量表在患儿中的信效度研究

Reliability and validity testing of the Chinese version Braden QD Scale in children

目的对Braden QD压力性损伤风险评估量表进行汉化并检验其信效度。方法在获得原量表作者授权后,对原量表进行翻译、回译、检译、跨文化调适以及预调查,形成中文版Braden QD量表;采用方便抽样法选取323例住院患儿进行问卷调查,以测量量表的信度和效度。结果量表的Cronbach′sα系数为0.760,折半信度为0.820,各条目删除后新的Cronbach′sα系数均较删除前的Cronbach′sα系数低,组内相关系数为0.991(P<0.01);量表水平内容效度指数和条目水平内容效度指数均为1.000,探索性因子分析共抽取2个公因子,累积方差贡献率为63.959%,验证性因子分析结果显示模型拟合良好。结论中文版Braden QD量表经验证后具有良好的信效度,可用于我国住院患儿压力性损伤风险评估。

Objective To make a Chinese version of the Braden QD Scale and test its reliability and validity.Methods After obtaining the permission from the author of the original Braden QD Scale,the scale was translated,back-translated,checked,cross-culturally adjusted and pilot tested to form the Chinese version.Convenient sampling method was used to select 323 hospitalized children to measure the reliability and validity of the Chinese version.Results The Cronbach′sαcoefficient of the scale was 0.760 and the split-half reliability was 0.820.The new Cronbach′sαcoefficients after the deletion of each item were lower than those before deletion,and the intra-group correlation coefficient was 0.991(P<0.01).Both scale-level and item-level content validity indexes were 1.000.Two common factors were extracted by exploratory factor analysis,and the cumulative variance contribution rate was 63.959%.The results of confirmatory factor analysis showed that the model fitted well.Conclusion The Chinese version of Braden QD Scale has good reliability and validity and can be used to evaluate the risk of pressure injury in hospitalized children in China.
