To evaluate the validity and reliability of the Thai version of Children Dermatology Life Quality Index (CDLQI).
CDLQI was translated to Thai and approved by Lewis-Jones MS and Finlay AY The patients, 4- to 15-year-old, with skin diseases and with problems unrelated to the skin were included to complete this questionnaire. Some patients with skin diseases were randomly selected to complete the CDLQI again seven days later to test the reliability. The time to complete the questionnaire was recorded.
Two hundred six children, which consisted of 113 patients with skin diseases (26 of this group answered the questionnaire twice) and 93 patients without skin diseases, were enrolled in the study. The mean age and sex distribution of the two groups were not statistically different (p 0.84, p 0.60, respectively). The mean CDLQI score of the patients with skin diseases was 7.5 ± 6.1. The validity of the CDLQI Thai version was p < 0.001 by comparing the scores from a variety of skin diseases with controls. Good reliability was demonstrated by assessing repeatability, which showed strong correlation coefficient of test-retest data with Spearman rank correlation coefficient r(s) 0.94 (p < 0.001). The Cronbach's coefficient alphas showed high internal consistency of the individual item (0.87). The average time to complete all questions was 4.5 ± 2.5 minutes. The younger age group spent longer time than the older age group (p < 0.001).
The Thai version of CDLQI has good validity and reliability. It should be used to measure quality of life in the management of skin diseases in Thai pediatric patients.
评估泰语版儿童皮肤病生活质量指数（CDLQI）的有效性和可靠性。
CDLQI被翻译成泰语，并经Lewis-Jones MS和Finlay AY批准。纳入4至15岁患有皮肤病以及患有与皮肤无关问题的患者来完成这份问卷。一些患有皮肤病的患者被随机挑选在七天后再次完成CDLQI以测试可靠性。记录完成问卷的时间。
206名儿童参与了该研究，其中包括113名患有皮肤病的患者（该组中有26名回答了两次问卷）和93名无皮肤病的患者。两组的平均年龄和性别分布无统计学差异（分别为p = 0.84，p = 0.60）。患有皮肤病的患者CDLQI平均得分为7.5±6.1。通过将各种皮肤病的得分与对照组进行比较，泰语版CDLQI的有效性为p < 0.001。通过评估重复性证明了良好的可靠性，重测数据的斯皮尔曼等级相关系数r(s)为0.94（p < 0.001），显示出强相关性。克朗巴哈系数阿尔法显示各个项目具有高内部一致性（0.87）。完成所有问题的平均时间为4.5±2.5分钟。较年轻年龄组比年长年龄组花费的时间更长（p < 0.001）。
泰语版CDLQI具有良好的有效性和可靠性。它应用于测量泰国儿科患者皮肤病管理中的生活质量。
