开发了一种羊的四点运动评分工具，并在10名全科兽医和10名羊农身上进行了测试。记录了34个不同运动得分的羊的视频片段，并随机分类。经过一段时间的训练，参与者使用了四个典型的运动分数的视频片段，然后对34个测试片段进行了评分。一个月后，参与者重复了训练和练习。观察者内部的可重复性很高：VS的加权kappa（kappa(W)）为0.81，农民为0.83。兽医和农民在观察者内的重复性没有差异（Wilcoxon sign rank P = 0.8）。当考虑视频包内得分的总体分布时，观察者之间的可重复性很高：VS的平均kappa(W)为0.73，农民的平均kappa(W)为0.72。然而，个体运动得分的可重复性仅为一般到中等。因此，建议在不同场合重复观察时，由同一观察者进行。
A four-point locomotion scoring tool for sheep was developed and tested on 10 general practice veterinary surgeons (VS) and 10 sheep farmers. Thirty-four video clips of sheep displaying different locomotion scores were recorded and randomly assorted. Following a set period of training using four other video clips typical of the four locomotion scores, participants then scored the 34 test clips. The participants repeated the training and the exercise one month later. There were high levels of intraobserver repeatability: weighted kappa (kappa(W)) 0.81 for VS and 0.83 for farmers. There was no difference in intraobserver repeatability between vets and farmers (Wilcoxon signed rank P = 0.8). When considering the overall distribution of scores within the video package, there were high levels of interobserver repeatability: mean kappa(W) 0.73 for VS and 0.72 for farmers. However, the repeatability for the individual locomotion scores was only fair to moderate. It is therefore recommended that when observations are repeated on different occasions they are made by the same observer.
