儿童皮肤病生活质量指数中文版的信度、效度评价

Reliability and Validity of Chinese Revision of the Children's Dermatology Life Quality lndex

目的评估儿童皮肤病生活质量指数（CDLQI）中文版的信度和效度、方法对广东省中医院151名儿童皮肤病患者进行CDLQI中文版的测试、结果重测信度，计算组内相关系数（1CC）为0．820；Guttman分半信度为0．814；Cronbach’s α系数为0．816各条目得分与其维度得分之间相关系数r均在0．540以上；各维度间的相关系数波动在0．232～0．452；除日常生活领域，各维度与总分的相关系数均在0．60以上、以主成分分析法进行因素萃取．并以Varimax法进行因素转轴，共萃取累计解释变异量大于83．09％的因素。皮肤病患者与其他疾病及健康者CDLQI分值的分布差异有统计学意义（Z=-7．207．-7．164；P=0．000）、结论CDI，QI中文版具有比较好的信度和效度，可在临床研究中将其用于儿童皮肤病生活质量的评估。

Objective To assess the reliability and validity of the Chinese version of the Children＇s Dermatology Life Quality lndex（CDLQI）. Methods The Chinese version of CDLQI was administered to 151 disease patients in Guangdong Provincial Hospital of TCM. Results The intra class correlation between test and retest was 0. 820, Guttman was 0.814 ;The C ronbach＇s α coeficients of the index was 0.816. The correlation between items and factors were above 0.540. The correlation between the factors were 0. 232 - 0. 452. Except the factors of daily life, the correlation between the factors and the index were above 0.60. Principal axis factoring analysis yielded a six-factor solution which contributed to 83.09% of the cumulative variance. The difference of CDLQI scores between skin disease patients and other disease patients was statistically significant （Z = - 7. 207, P = 0. 000） , and same to skin disease patients and health child （ Z = - 7. 164, P = 0.000 ）. Conclusion The Chinese version of the Children’s Dermatology Life Quality lndex（CDLQl） has good reliability and validity,it can be applied in the clinical and scientific researches.
