Metric effects of taking tears out of the Wong-Baker faces pain scale
Metric effects of taking tears out of the Wong-Baker faces pain scale
[version 1; not peer reviewed]Children integrated the two pain informers through an averaging model, which allowed deriving functional scale values (interval level) and measures of relative importance (ratio level) for each face. The range of the WBFPRS without tears was reduced. The WBFPRS came slightly closer to the equal interval ideal. All its faces were evaluated as more intense than in the tears-in version, except for the last one. The relative importance of this face was sizeably diminished.
