慢性病生命质量量表体系中慢性胃炎量表测评

Evaluation on validity and responsivity of the chronic gastritis scale of systemic quality of life instrument for chronic diseases

目的分析慢性病患者生命质量测定量表体系之慢性胃炎量表(QLICD-CG)的效度和反应度。方法用QLICD-CG对124例慢性胃炎患者在住院治疗前后进行测试,从而对量表的效度和反应度进行评价。效度从内容效度、结构效度、效标效度3个方面反映,其中量表的结构效度用条目和亚领域及领域的相关情况、因子分析反映。反应度通过比较治疗前后各领域患者生命质量的得分均数,计算各领域得分变化的百分比和标准化反应均数(SMR)值来考评。结果量表各条目与所属亚领域或领域的相关均大于该条目与其他亚领域或领域的相关,且相关系数r>0.6;量表可以测出患者治疗前后各领域的生命质量变化,其中最显著的为特异模块领域(SRM=1.79)及其上腹不适亚领域(SRM=1.72)。结论慢性胃炎患者生命质量测定量表(QLICD-CG)具有较好的效度、反应度和临床可行性,可以作为我国慢性胃炎患者生命质量的测评工具。

Objective To analyze the validity and the responsivity of the chronic gastritis scale of the systemic quality of life instrument for chronic diseases （ QLICD - CG）. Methods 124 cases of chronic gastritis inpatients were measured by QLICD - CG before and after treatment. The validity of the instrument was evaluated by the content validity, constructive validity and criterion validity with item - facets and item - domain correlation analysis and factor analysis. Responsivity was evaluated by comparing the scores between the domains and facets before and after treatment with the change percentage in each facets score and the index of SRM. Results Almost all of the correlation coefficients between each item and it＇ s facet or domain were higher than the item with other facet or other domains, and most of those correlation coefficients were above 0.6. The clinical changes of the each domain due to the treatment can be detected by the scale,especially in the specific domain （ SRM = 1.79 ） and the facet of the unwell of upper abdomen （ SRM = 1.72）. Conclusion The QLICD - CG is valid sensitive and reasonable operation in clinical settings, and it can be used to assess quality of life for patients with chronic gastrifis.
