慢性病生命质量量表中慢性胃炎量表研制

Development and reliability evaluation of the chronic gastritis scale quality of life instruments for chronic disease

目的研制慢性病患者生命质量测定量表体系之慢性胃炎量表(QLICD-CG),并对其信度进行考评。方法采用共性模块和特异模块相结合的方式,经过文献回顾、核心小组讨论、重要性评分、统计筛选等过程研制量表;通过124名慢性胃炎患者的测定计算内部一致性系数α、重测相关系数r来反映量表的信度。结果慢性病患者生命质量测定量表之慢性胃炎量表[QLICD-CG(V1.0)],其共性模块(QLICD-GM)含30个条目,慢性胃炎特异模块包含5个亚领域14个条目,总量表及各领域的内部一致性系数α、分半信度和重测相关系数分别为:总量表0.892,0.733,0.98;躯体功能0.784,0.851,0.958;心理功能0.878,0.891,0.99;社会功能0.686,0.678,0.955;慢性胃炎特异模块0.728,0.799,0.97。结论QLICD-CG(V1.0)具有较好的信度和可行性。

Objective To develop and evaluate the reliability of the chronic gastritis scale of the quality of life instruments for chronic diseases（QLICD-CG）. Methods Based on the strategy of combination of general model and specific ones, QLICD-CG was developed by the methods of literature review, individual interview and focus group discussion. The scale was used to 124 inpatients of chronic gastritis. The reliability of the instrument was assessed by Cronbach a and the test-retest correlation coefficients for each domain and facet. Results The QLICD-CG （V1.0） was developed with 30 items of general module and 16 items of specific module. The coefficients of internal consistency, split-half and the test-retest reliability of total scores and all domains are as follows： total scores 0. 892, 0. 733, 0.98, physical functioning domain （PHD） 0. 784, 0.851, 0.958, psychological functioning domain（PSD） 0. 878, 0. 891,0.99, social functioning domain （SOD） 0. 686, 0. 678, 0.955, the specific module of chronic gastritis（CGD） 0. 728, 0. 799, 0.97. Conclusion The QLICD-CG（V1.0） can be used to assess the quality of life for patients of chronic gastritis with good reliability and reasonable operation in clinical settings.
