慢性乙型肝炎患者中医生存质量量表(测试版)的信效度检验

Reliability and Validity test about chronic hepatitis B patients quality of life scale of traditional Chinese medicine( Test Version)

目的：对慢性乙型肝炎（CHB）患者中医生存质量量表（测试版）行信效度检验。方法：400例CHB患者通过＂慢性乙型肝炎患者中医生存质量量表（测试版）＂的问卷调查。结果：1CHB患者中医生存质量量表（测试版）信度检验：全卷分半信度系数为0.997（P〈0.01）;内部一致性分析结果显示：量表总分、肝经领域、肝络领域、情志领域、部候领域得分的Cronbach alpha系数分别为0.958、0.874、0.887、0.918、0.856。2CHB患者中医生存质量量表（测试版）效度检验：维度相关性分析显示各条目得分与其所在维度得分之间相关性均较大。各维度与总量表分的P相关系数〉各维度之间的P相关系数,各维度得分与总分之间的P相关系数均在0.84以上（P均〈0.01）;各维度之间的P相关系数在0.580~0.781之间（P均〈0.01）,其中部候维度与情志维度相关性较大,肝经维度与肝络维度相关性较大（P均〈0.01）。3主成分因子分析：72条条目中,除条目50、57、69因子负荷〈0.4外,其余均〉0.4,每个因子的组成条目都能够被比较合理地解释。量表中的每个条目都在其所属的因子上有较高的负荷值,而在其他因子上的负荷值较低。结论：CHB患者中医生存质量量表（测试版）有较强的可行性;量表所测定的内容具有同源性,信度佳,各维度间有充分的内部一致性;该量表结构效度好,符合心理测量学的要求。

Objective：To evaluate the feasibility、reliability and validity of TCM Quality of Life Scale for CHB （Test Version）.Methods：TCM Quality of Life Primary Scale for CHB was conducted among 400 patients of CHB.Results：①Reliability-testing： Spearman-Brown split coefficient of total was 0.997（P 〈0.01）;Cronbach-αcoefficient of score of total, Liver Meridian Subscale,Liver-collaterals Subscale,Emotion Subscale and Buhou Scale were 0.958, 0.874, 0.887, 0.918, 0.856, respectively.②Validity-testing：Correlation analysis of four subscales showed that there were significant correlations between score of each item and total score of the subscale which item belonged to.Apart from I-tem 5 and Item 9,Pearson correlation coefficient between Liver Meridian Subscale and its remaining items were higher than 0.4（P 〈0.01）.A-part from Item 31,Pearson correlation coefficient between Liver-collaterals Subscale and its remaining items were higher than 0.4（P 〈0.01）. Pearson correlation coefficient between Emotion Subscale and its items were all higher than 0.4（P 〈0.01）.Apart from Item 67, Pearson corre-lation coefficient between Buhou Subscale and its remaining items were higher than 0.4（P 〈0.01）.Pearson correlation coefficient between total and each subscale were higher than them between each subscale.All Pearson correlation coefficient between total and four subscales were over 0. 84（P 〈0.01）.All pearson correlation coefficient between each subscale were 0.58 ~0.781（P 〈0.01）.There were siginificant correlations be-tween Buhou Subscale and Motion Subscale,Liver Meridian Subscale and Liver-collaterals Subscale（P 〈0.01）.③The principal component fac-tor analysis：The factors were rotated by Varimax ,then calculated the factor loading.The results showed：besides Item 50,Item 57 and Item 69, the factor loading of each remaining items was over 0.4.Conclusion：TCM Quality of Life Scale（Test Version） has been proved to have stronger feasibility and a a good overall internal consistency.It also has high reliability and fair validity.
