背景和设计。 - 对于大多数没有丰富经验或求助于高质量、标准化基线照片的从业者来说，评估皮肤光损伤的严重程度及其对治疗的反应是不切实际的考虑。 为了解决这个问题，一个九点的光致发光标准量表开发使用的照片的主题代表等级的光损伤从无到严重。 该量表在与传统的和广泛使用的书面描述性量表进行并排比较中进行了正式测试。 一个由7名评分员组成的小组使用两种量表对两组25张光损伤个体的照片进行评分，并计算量表的一致性和重复性。 - 与描述性量表相比，光数值量表在评分者之间表现出更高的一致性（机会校正一致性分别为0.31和0.11，P <0.0001），两种方法之间的重复性无显著差异。 - 本研究表明，光数值标准量表在准确评估皮肤光损伤方面上级现有方法，并将有助于辅助研究皮肤修复剂对该适应症的疗效。
Background and Design. -The assessment of the severity of cutaneous photodamage and its response to treatment is an impractical consideration for most practitioners without extensive experience or recourse to high-quality, standardized, baseline photographs. To address this problem, a nine-point photonumeric standard scale was developed using photographs of subjects representing grades of photodamage from none to severe. This scale was formally tested in a side-by-side comparison with a conventional and widely used written descriptive scale. A panel of seven graders used both scales to score two sets of 25 photographs of photodamaged individuals, and the intergrader agreement and repeatability for the scales were calculated.Results. -The photonumeric scale demonstrated significantly greater agreement between graders than did the descriptive scale (chance-corrected agreements of 0.31 and 0.11, respectively, P < .0001) with no significant difference in repeatability between the two methods.Conclusions. -This study demonstrates that the photonumeric standard scale is superior to existing methodology in the accurate assessment of cutaneous photodamage and would be useful adjunct to studies of the efficacy of skin repair agents for this indication.
