OBJECTIVE
To describe the development and validation of the 5-grade photographic IBSA inner upper arm scale.
METHODS
From 2 real-life pictures, a scale made up of 5 morphed images showing increasing severity of inner upper arm laxity was created. For validation, a set of 50 images (half of which real and the other morphed) was developed and sent to 5 trained physicians in two rounds 30 days apart. Raters' task was to make a selection of each image according to the given scale. Inter-rater and intra-rater reliability were evaluated in both rounds.
RESULTS
As to intra-rater reliability, single-rater kappa scores between 0.74 and 1.00 and a global kappa score of 0.846 were observed, while inter-rater agreement was calculated with intra-class correlation coefficient reporting scores higher than 0.91, which indicate excellent reliability.
CONCLUSION
IBSA inner upper arm laxity scale proved to be a validated and reliable tool.
目的
描述5级IBSA上臂内侧照片量表的开发与验证过程。
方法
从2张真实生活照片中，创建了一个由5张变形图像组成的量表，这些图像显示上臂内侧松弛程度逐渐增加。为了进行验证，开发了一组50张图像（其中一半是真实图像，另一半是变形图像），并分两轮（间隔30天）发送给5名经过培训的医生。评分者的任务是根据给定的量表对每张图像进行选择。在两轮评估中均评估了评分者间和评分者内的信度。
结果
关于评分者内信度，观察到单评分者kappa分数在0.74至1.00之间，全局kappa分数为0.846，而评分者间一致性通过组内相关系数计算，报告分数高于0.91，这表明信度极佳。
结论
IBSA上臂内侧松弛量表被证明是一个经过验证且可靠的工具。
