Many acne grading methods exist; however, there is no agreed-upon standard. Our objective was to create and validate a reproducible acne assessment scale for rating the severity of juvenile facial acne suitable for use in France and Europe.
The scale we created described the different types of acne lesions in a manner similar to global assessment scales used in clinical trials. The scale was then validated by seven expert dermatologists in the field of acne [the Global Evaluation Acne (GEA) group] first on 34 photographic cases of Caucasian acne patients and second by clinical examination of 22 acne patients.
There was good agreement in Investigators' assessments of acne both on photographs and patients (R = 0.8057; P < 0.0001, and R = 0.8437; P = 0.0015).
The GEA Scale is a global scale validated both on photographs and acne patients which can be used either in clinical research or by the dermatologist in his office.
存在许多痤疮分级方法，但尚无公认的标准。我们的目的是制定和验证一种可重现的青少年面部痤疮评估量表，用于评估法国和欧洲的痤疮严重程度，且适用于该地区。
我们制定的量表以类似于临床试验中使用的全球评估量表的方式描述了不同类型的痤疮病变。该量表随后由 7 位痤疮领域的专家皮肤科医生进行了验证[全球评估痤疮（GEA）小组]，首先对 34 例白种人痤疮患者的照片进行了评估，其次对 22 例痤疮患者进行了临床检查。
照片和患者的评估结果之间存在良好的一致性（R = 0.8057；P < 0.0001，和 R = 0.8437；P = 0.0015）。
GEA 量表是一种在照片和痤疮患者上均经过验证的全球量表，可用于临床研究或皮肤科医生的诊室中。
