Population norms are available for several generic health-related quality of life questionnaires, but rarely for disease- or specialty-specific questionnaires. The aim of our study was to calculate population norms for the Dermatology Life Quality Index (DLQI) score..
We conducted an online self-completed questionnaire survey on a large sample of the general Hungarian adult population. Respondents' socio-demographic characteristics and dermatology-related quality of life aspects were recorded. A total of 2,001 participants completed the questionnaire, with the average age of 48.2 (SD = 16.6) years, half of the respondents in our sample (n = 981) reported long-standing health problems. The average DLQI score was 1.9 (SD = 4.0) with women having a higher average (2.0, SD = 3.9) than men (1.8, SD = 4.0; p = <0.001). The DLQI score differed among age-groups with younger people having relatively higher DLQI averages. When the multivariate linear regression model was applied, it showed that young age, lower income and unemployment status were associated with higher DLQI scores, while controlling for the existence of skin disease (p < 0.05).
This study established DLQI population norms among the general population, which may provide a reference point in health-policy and financing decision-making.
有几种通用的与健康相关的生活质量问卷的人群正常值，但很少有针对特定疾病或专科的问卷。我们的研究目的是计算皮肤病生活质量指数（DLQI）评分的人群正常值。
我们对大量的匈牙利成年普通人群进行了在线自填式问卷调查。记录了受访者的社会人口统计学特征和皮肤科相关生活质量方面的情况。共有 2001 名参与者完成了问卷调查，平均年龄为 48.2（标准差=16.6）岁，我们样本中的一半（n=981）报告有长期健康问题。平均 DLQI 得分为 1.9（标准差=4.0），女性的平均得分（2.0，标准差=3.9）高于男性（1.8，标准差=4.0；p<0.001）。DLQI 得分在不同年龄组之间存在差异，年轻人的 DLQI 平均值相对较高。当应用多元线性回归模型时，结果表明年轻、低收入和失业与较高的 DLQI 得分相关，同时控制了皮肤疾病的存在（p<0.05）。
本研究确立了普通人群中的 DLQI 人群正常值，这可能为卫生政策和融资决策提供参考依据。
