BACKGROUND
Quality of life is increasingly recognized as an important measure in dermatology. The Skindex-29 is a self-administered questionnaire recently developed to measure comprehensively the complex effects of skin diseases on patients' quality of life.
OBJECTIVE
We aimed to provide further evidence of the reliability and validity of the Skindex-29 in a large sample of patients affected by a wide variety of skin diseases.
METHODS
An Italian version of the Skindex-29 was produced following accepted guidelines for the cross-cultural adaptation of questionnaires. All adult outpatients attending a dermatological hospital on predetermined days were given the Skindex-29 and the 12-item General Health Questionnaire (GHQ-12).
RESULTS
A total of 2,242 complete questionnaires were analyzed. The internal consistency and test-retest reliability of each scale were high. The factor structure of the Skindex-29 was strikingly similar to the one originally observed in American patients. The pattern of correlation with the GHQ-12 provided evidence of convergent validity of the Skindex-29.
CONCLUSION
The instrument seems to measure three fundamental dimensions of skin health-related quality of life.
背景
生活质量在皮肤病学中日益被视为一项重要指标。Skindex-29是最近开发的一份自我管理问卷，用于全面衡量皮肤病对患者生活质量的复杂影响。
目的
我们旨在为Skindex-29在大量受多种皮肤病影响的患者样本中的可靠性和有效性提供进一步证据。
方法
按照公认的问卷跨文化改编指南制作了意大利语版的Skindex-29。在预定日期到皮肤科医院就诊的所有成年门诊患者均接受了Skindex-29和12项一般健康问卷（GHQ-12）。
结果
共分析了2242份完整问卷。每个量表的内部一致性和重测信度都很高。Skindex-29的因子结构与最初在美国患者中观察到的结构惊人地相似。与GHQ-12的相关模式为Skindex-29的收敛效度提供了证据。
结论
该工具似乎能够衡量皮肤健康相关生活质量的三个基本维度。
