慢性病患者生命质量测定量表共性模块的二次评价研究

Evaluation of the General Module of Quality of Life Instruments for Chronic Disease

目的采用大样本评价慢性病患者生命质量测定量表的共性模块(QLICD-GM)的信度、效度和反应度。方法应用QLICD-GM量表对8种慢性病1 024例患者进行测试,采用经典测量理论(CTT)对QLICD-GM的信度、效度和反应度进行评价。结果 QLICD-GM各个领域及侧面的重测相关系数均大于0.8;克朗巴赫α系数除了生理功能领域得分(0.35)较低以外,其他领域得分均大于0.6。各条目与所属侧面相关性均较大,而与非所属侧面相关性均较小。比较得分的均数,发现除心理功能领域、认知、社会支持、社会影响侧面的差异无统计学意义(P>0.05)外,其余差异均有统计学意义(P<0.05)。结论 QLICD-GM具有较好的信度、效度及反应度,能够作为我国慢性病患者生命质量的测评工具。

Objective To evaluate the credibility,validity and responsiveness of the General Module of the Quality of Life Instruments for Chronic Disease（QLICD-GM）.Methods Totally 1 024 patients with chronic diseases were evaluated with QLICD-GM.Classical Test Theory（CTT） was used to evaluate the credibility,validity and responsiveness of QLICD-GM.Results The test-retest correlation coefficient of each dimension and facet of QLICD-GM were all higher than 0.8.The Cronbach′s α coefficients of all items exceeded 0.6 except the dimension of physiological function（0.35）.The items had a relatively high correlation with their corresponding facets,and a relatively low correlation with other facets.The mean scores of most facets（except psychological function,cognition,social support,and social influence） showed significant differences before and after treatment（P〈0.05）.Conclusion QLICD-GM has relatively high credibility,validity,and responsiveness in measuring the quality of 1ife among patients with chronic diseases.
