摘　　要：背景与目的:我们已经开发了癌症患者生命质量测定量表体系共性模块(quality of life instruments for cancer patients-general module,QLICP-GM),但其心理测量学特性有待考评。本研究拟考评QLICP-GM的信度与效度。方法:用QLICP-GM对600例肺癌、乳腺癌、大肠癌、胃癌和头颈癌患者的生命质量进行测定和评价,用相关分析、配对t检验、等效检验、结构方程模型等统计学方法分析QLICP-GM的信度和效度;同时与FACT-G量表测定和评价结果比较,分析QLICP-GM的效标效度。结果:QLICP-GM各领域及总量表的重测信度均在0.85以上,除社会功能外各领域内部一致性信度α值均在0.70以上,总量表的α值和分半信度分别为0.88和0.93;相关分析与结构方程模型分析显示量表有较好的结构效度;与FACT-G的相关分析显示有较好的效标关联效度。结论:QLICP-GM具有较好的信度和效度,可用于癌症患者生命质量测定。BACKGROUND ＆ OBJECTIVE： The general module of the system of quality of life instruments for cancer patients （QLICP-GM） has been developed by us, but its psychologic properties need to be evaluated. This study was to evaluate the reliability and validity of QLICP-GM. METHODS： The QOL data of 600 patients with lung cancer, breast cancer, colorectal cancer, gastric cancer, and head and neck cancer were analyzed by paired t-tests, correlation analysis, equivalence tests, and structural equation models to evaluate QLICP-GM. RESULTS, The test-retest reliability for all domains and the overall scale was above 0.85. Internal consistency α values for all domains except social function domain were above 0.70. The α value and split-half reliability of the overall scale were 0.88 and 0.93, respectively. Correlation analyses and structural equation models displayed good construction validity of the scale. It also showed good criterion-related validity when FACT-G was used as the criterion. CONCLUSION： QLICP-GM can be used to measure QOL for cancer patients with good reliability and validity.
