摘　　要：目的考评慢性肾衰竭患者生命质量测定量表QLICD-CRF的信度。方法用QLICD-CRF量表调查164例慢性肾衰竭患者,采用相关性分析对两次数据进行重测信度评价,采用克朗巴赫α系数来评估内部一致信度;基于概化理论,计算各领域概化系数和可靠性系数。结果慢性肾衰竭患者生命质量测定量表不同领域和侧面重测信度系数均在0.8以上;总体内部一致信度为0.90,总体量表分半信度为0.76;QILCD-CRF量表四个领域概化系数和可靠性指数都比较好。结论 QILCD-CRF量表具有较好的信度。Objective To evaluate reliability of the quality of life（QOL） instrument for patients with chronic renal fail- ure（QLICD-CRF）. Methods The QLICD-CRF was used to measure QOL in 164 patients with chronic renal failure, and the data were used to assess the test-retest reliability by correlation analysis, to calculate internal consistent reliability in terms of Cronbach＇s alpha coefficients for each domain/facet, and to compute generalized coefficients and reliability coefficients based on generalizability theory. Results The test-retest reliability of each domain and facet was above 0. 8, the total internal consis- tency reliability was 0.90, total split-half reliability was 0. 76 ; generalized coefficients and reliability coefficients of the four domains were good. Conclusion The QILCD-CRF has a good reliability.
