| 目的评价简体中文版皮肤病生活质量指标(DLQI)量表的信度和效度. 方法对就诊皮肤科门诊的236例患者进行DLQI量表的测量, 并计算其分值, 用可靠性分析和因子分析进行评估. 结果 DLQI量表克伦巴赫系数为0.87, 折半信度为0.85, 各维度之间相关性较高为0.4024～0.6569, 因子分析发现单因素能够代表DLQI量表的大多数因子. 结论 DLQI量表为简单有效的皮肤病生活质量测评工具, 且具有较好的信度和效度. |

| Objective Since the dermatology life quality index (DLQI), a self-administered general dermatology quality of life instrument, was originally developed and published in a dermatology clinic at University hospital of Wales, our goal was to popularize the disease-specific scale used in measuring the quality of life of patients with skin diseases and to assess the reliability and validity of its Chinese version. Methods We administered the DLQI to 236 out-patients attending our dermatology clinic and results that had been found by those who originated the DLQI，were examined. The reliability and validity of DLQI were assessed by means of reliability analysis and factor analysis. Results Overall, the DLQI seemed easy to administer and could be completed within 3 minutes. The internal consistency coefficient rates of this unidimensional measure were 0.87(Cronbach's alpha) and 0.85(Spearman-brown, s)with high inter-correlations found between the dimensions with a correlation coefficient ranging from 0.4024-0.6569. Factor analysis resulted in a unidimensional pattern, which supported the use of a total DLQI-C score. Conclusion DLQI was an easy and efficient instrument for assessing the quality of life in patients with dermatological problems and with better reliability and validity. Thus, it could be used in both research and clinical settings in China. |
