慢性肝炎患者生命质量测定量表研制与考评

Development and Evaluation of Quality of Life Instruments for Chronic Diseases-Chronic Hepatitis

目的研制和评价慢性病患者生命质量测定量表体系中的慢性肝炎量表(QLICD-CH)。方法结合中国文化背景进行量表(QLICD-CH)研制,并用此量表调查108例慢性肝炎住院患者,对QLICD-CH的信度、效度和反应度进行评价。结果该量表各个领域克朗巴赫系数(Cronbach'sα)均>0.7,分半信度系数多数>0.6,重测相关系数均>0.9。共性模块提取9个公因子,特异模块提取4个公因子,涵盖大部分条目信息。以汉化版的医学结局调查表(SF-36)各个领域得分作为效标,QLICD-CH各个领域及量表总分与SF-36相应效标的相关程度较好。QLICD-CH第一次和第三次测定得分进行比较,除了心理功能领域、社会功能领域外,其他领域得分治疗前后比较,差异均有统计学意义(P<0.01)。结论 QLICD-CH具有较好的信度、效度、反应度,可作为中国慢性肝炎患者的生命质量测评工具。

Objective To develop and evaluate the quality of life instruments for chronic diseases-chronic hepatitis（QLICD-CH）. Methods The scale was developed in accordance with Chinese culture background and assessed by analyzing data from 108 inpatients in the aspects of validity,reliability and responsiveness. Results Cronbach＇s Alpha of each domain exceeded 0.7,the split-half was also above 0.6,test-retest reliability of the scale,as assessed with the correlation coefficient was above 0.9;nine principle components were extracted from the general module of instrument,four principle components were extracted from the specific module,which reflected contents of most items.The correlations between coefficients of each domain as well as total score of QLICD-CH and SF-36 were fairly high.Except from psychological domain,social domain,scores of the other domains showed statistically significant differences before and after treatment（P0.01）. Conclusion The QLICD-CH has good validity,reliability and responsiveness and can be used in the quality of life assessment of patients with chronic hepatitis.
