胃癌患者生活质量问卷(QLQ-STO22)中文版的制定

目的:将QLQ-STO22引入国内,并评价其可行性、信度和效度。方法:以2003年6月1日至12 月31日在某市三家医院入院治疗的胃癌患者为研究对象。调查内容主要包括一般状况、简明病情调查表及QLQ-STO22。结果:重复测量前后比较,STO22量表各个维度的ICC 值均大于0.75;Cronbaeh'a 系数为0.80; 量表的分半信度系数分别为0.78。表明量表的重测信度、分半信度和内部一致性良好。对STO22量表的各个维度做因子分析,得到3个因子,它们分别能解释总体方差的72.8%,各公共因子在相应项目上的因子载荷均>0. 5,表明该量表具有较满意的结构效度。结论:QLQ-STO22中文版具有较好的信度和效度。

Development of Chinese Version of QLQ-STO22

Objectives:To translate the English version of Quality of Life Questionnaire of Stomach 22 into Chinese,and to test the reliability and validity of the Chinese Version of QLQ-STO22.Methods:From 1st June to 31st December,2003,140 patients with gastric cancer were sampled as study participants in three hospitals using cluster sampling method.All participants were interviewed with QLQ-STO22 Chinese version by the investigators who were trained in advance.Results:Nearly all ICCs of scales of STO22 were above 0.75;the split-half reliability coefficient is 0.78 and the Cronbach'a coefficient is 0.80.These results proved that the questionnaires had good test-retest reliability,split-half reliability and internal consistency.Three common factors were extracted by factor analysis,which ccould account for more than 60% of total variance and factor loads of the three common factors were above 0.5 in related items.Conclusion:QLQ-STO22 has good reliability and validity,which is available for the study of life quality among Chinese gastric cancer patients.
