Influence of Rater Training on Inter- and Intrarater Reliability When Using the Rat Grimace Scale.

ABSTRACT: Rodent grimace scales facilitate assessment of ongoing pain. Reported rater training using these scales varies considerably and may contribute to the observed variability in interrater reliability. This study evaluated the effect of training on interrater reliability with the Rat Grimace Scale (RGS). Two training sets (42 and 150 images) were prepared from acute pain models. Four trainee raters progressed through 2 rounds of training, scoring 42 images (set 1) followed by 150 images (set 2a). After each round, trainees reviewed the RGS and any problematic images with an experienced rater. The 150 images were then rescored (set 2b). Four years later, trainees rescored the 150 images (set 2c). A second group of raters (no-training group) scored the same image sets without review with the exp
