慢性病患者生命质量测定量表体系——系统性红斑狼疮量表的研制及信度与效度分析

目的研制慢性病患者生命质量测定量表体系中的系统性红斑狼疮量表QLICD—SLE（V2．0）,并对它的信度、效度进行分析。方法通过对143名系统性红斑狼疮病人的测量来考评该量表的信度和效度。结果系统性红斑狼疮量表QLICD—SLE（V2．0）,由29个条目的共性模块（QLmD—GM）和19个条目的特异模块构成。各领域及总量表的Cronbach＇s α系数、分半信度和重测信度分别为：生理功能领域：0．74,0．83,0．74;心理功能领域：0．87,0．91,0．81;社会功能领域：0．75,0．79,0．72;特异模块领域：0．84,0．86,0．88;总量表：0．69,0．96,0．67。量表各条目和本领域得分的相关系数除GPS10、SLE14、SLE17这3个条目外都在0．60以上,且明显大于各条目和其他领域的相关系数。特异模块、共性模块因子分析结构均与理论构想一致。量表各领域与效标各领域显著相关。结论QLICD—SLE（V2．0）具有较好的信度、效度和临床可行性。

Development and analysis on reliability and validity of the systemic lupus erythematosus scale of the system of quality of life instruments for patients with chronic disease

Objective To develop and analyze the systemic lupus erythematosus scale QLICD-SLE （ V2. 0） of the system of quality of life instruments for patients with chronic diseases. Methods The scale was used for 143 patients with systemic lupus erythematosus. The validity and reliability of the scale were evaluated. Results The QLICD-SLE （ V2. 0） consists of 29 items of general module（QLICD-GM） and 19 items of specific module. The coefficients of internal consisten- cy（ Cronbach＇s α, split-half and the test-retest reliability of all domains and total scores were as follows ： physical functio- ning domain（PHD） ： 0.74, 0. 83,0.74 ; psychological functioning domain（ PSD ） ： 0. 87,0.91,0. 81 ; social functioning domain （SOD） ： 0. 75,0. 79,0. 72 ; the specific module of systemic lupus erythematosus ： 0. 84,0. 86,0. 88 ; total scores 0. 69,0. 96,0. 67. All of the correlation coefficients between item and its domain were above 0. 60 except three items （GPS10 ,SLE14 and SLE17 ） , and all of those correlation coefficients were higher than the item with other domains. The factor analysis structure of the special module and general module was consistent with theoretical conceiving. Domains of QLICD-SLE（V2. 0） were correlated significantly with its criterion. Conclusions The QLICD-SLE（V2. 0） has high relia- bility, validity and clinical feasibility.
